I've done a lot of research on who exactly invented shampoo for commercial use. I've found a lot of sources cite Kasey Hebert with Canthrox, but there's no definite evidence about who Kasey Hebert is exactly. Is there anyone who can provide information about this? [1] Edavid88 ( talk) 07:48, 9 January 2021 (UTC)
The article does not really give the history of shampoo in the sense of saying when it was discovered/invented in Bengal, how it was made or first used, etc. It simply states that Deen Mahomet introduced it to Britain. If the pre-British history of shampoo is not known, perhaps a statement to this effect should be made?
According to http://www.indianmuslims.info/book/export/html/183, by the time Deen Mahomet moved to London to market curry and shampoo, he had been a Christian for over 20 years. Although his parents were Muslims, the family lived Bihar, which was predominantly Hindu, and also had large Buddhist, Sikh and Jain minorities. It is therefore not correct to associate the invention of shampoo with Islam (or with any other single religion) unless the individual/community that first discovered it can be positively identified.

There are no references to claims that Sodium dodecyl sulfate is carcinogenic. Though the SDS page there is reference to the urban legend. I think that clean up crews have been overzealous in removing claims of this sort that are not well supported. People come to wikipedia for perspective, not just lists of links to what is elsewhere. Explaining the chemistry/toxicity issues or linking to where they are explained with links that someone who doesn't already know the connection... that is what this article needs to do better. The social context is erased when all we write about are scientific facts about materials instead of also including ideas that require more difficult referencing. Sorry to sound so negative here but I am seeing this issue in too many articles these days. Rusl 23:26, 2 August 2007 (UTC)
Is there anyone who knows about the basic chemical differences about shampoos that claim to be a volumizer, clarifying, dry vs oily, and about a million other types? In a side note, some shampoos have hair dyes and toners in them to subtly maintain or change the color of your hair. For example, some people use purple based shampoos to make their hair less brassy and yellow (many blondes use this to make the hair white). This is rumored to be where the term blue haired lady comes from when older women leave this in their hair to long to tone they're gray. Shouldn't this be written somewhere with a description?
Short answer: There is no real difference between those shampoos. Longer answer: Marketing claims and chemistry can be found at the sites of companies that sell shampoo ingredients. Try:( http://www.ispcorp.com/) Even longer answer: A book could be written on this subject. In fact, some have been written. The unfortunate problem is that much of this information isn't published anywhere on the web. Since it's not published, it can't be cited. If it can't be cited, it has no place in Wikipedia. Sorry, but that's the catch-22 here. Bobzchemist 16:30, 11 January 2007 (UTC)
The accurate answer: there are substantial differences chemically between soap, detergent and shampoo. Read any standard organic chemistry text for the details. pH plays a huge part. There are differences between people and species with respect to the chemistry of hair and skin. Whether or not a shampoo is antibacterial can also impact on the normal flora of the skin.
An organic chemist and a dermatologist can elucidate these factors here. — Preceding

Medium Answer, the basic ingredients are typically the same, however, the ratios and blends do vary within bands so that various characteristics are optimised. If you follow the ispcorp link, you'll find additives for volumising for instance.

htf do youmake homemade shampoo. i wanna know cause i'm kinda poor. thanks to anyone who can help.
I, too, would like to know, if anyone has the answer. I think it's made from lye and fat or something though.
All shompoos are made from Synthetic Detergents, these days. Short Answer: Use bath soap. Longer answer: It is not possible to save money by making your own. You will pay more for the ingredients than you will for the finished shampoo. Buy the cheapest generic stuff you can find, it will work 90% as good as the most expensive shampoo on the market. Bobzchemist 20:29, 24 October 2005 (UTC)
There are brands of shampoo that are extremely inexpensive. Go to a dollar store. I do not believe you can purchase the necessary chemicals to make your own shampoo. If you have ever washed your hair with soap you'll understand why - they have to use cleaners that do not strip out the necessary oils. When this happens, your scalp produces oil faster, your hair becomes much more succeptible to breakage, splitting and fraying, and it is almost instantly unmanageable. The detergents used in shampoo have to balance things out, rather than stripping them out. I suppose an alternative is to go with dreads. JMPZ 05:17, 24 April 2006 (UTC) Using bar soap to wash hair is possible, but not desirable, mainly because the pH of an average soap bar made from saponification of fats/oils with lye (Sodium Hydroxide) is quite high at around pH 10 or therabouts. This causes the scales on the hair shaft to fluff out giving a higher risk of felting or interdigitation. If you rinse afterwards with something acidic like lemon juice or vinegar, you may well get away with it, but TBH with cheap own label shampoo available its not really worth it. Use a cheap shampoo or shower gel instead 20:31, 30 September 2007 (UTC)
First sentence is: "A shampoo is a traditional Indian and Persian body massage given after pouring warm water over the body and rubbing it with extracts from herbs. It can be used in conjunction with a conditioner for optimal results, but it is not a necessity."
Conditioners are relevant to Indian and Persian body massage? Otherwise we're getting confused here.
"Shampoo is also available in solid form, allowing it to be rubbed onto the hair. This has the advantage of having the shampoo easily carried, but also has the disadvantage of working less efficiently on longer hair."
What is "having the shampoo easily carried" intended to mean? That the shampoo can easily be carried when travelling? That it can easily be spread in the hair? -- Brolin Empey 23:55, 2005 August 2 (UTC)
I believe that the "solid" shampoo subcategory is actually a subtle advertisement. I was only able to find one company manufacturing it. I'm calling it non-notable, and I will delete it unless someone objects and can show a citation from more than one company. Bobzchemist 21:17, 9 February 2007 (UTC)
There have been various commercial solid shampoos going back at least to Neutrogena Solid Soap Shampoo ca. 1970. (That's not counting soaps which were labeled as for shampooing among other uses, e.g. "Lifebuoy Shower, Bath and Shampoo Soap", as it was called for a while.) There are also recipes for homemade shampoo bars at soapmaking sites. There was a brand of shampoo bar from Fla. a few years ago and since discontinued based on disodium lauryl sulfosuccinate. If somebody cited brands now, those would be advertisements. --robgood@bestweb.net 216.179.1.232 ( talk) 22:55, 24 March 2009 (UTC)
A lot of hair care products are adversted as containing 'Pro-Vitamins'. My understanding was that a pro-vitamin was something the body (usually the liver) could convert into a vitamin when required. For example, betacarotene would be considered 'pro- vitamin A.
Is there any benefit in adding 'pro-vitamins' to hair care products, or is this just impressive-sounding marketing hype? Are there any good refernces on this subject? -- PJF (talk) 04:23, 27 Feb 2005 (UTC)
Panthenol does have an ability to bind electrostatically to the hair shaft to give a conditioning effect that can be percieved by the user in the same way that quaternery based conditioners (The same as used in fabric softener)do. If anyone says that they are "Feeding the hair" this is guff, as the hair shaft is dead (Only the bulb under the skin is actually alive). Rememeber that this is a cosmetic product, so the only effects you will get are, by definition, cosmetic Valueaddedwater 20:35, 30 September 2007 (UTC)
Does anyone have any information about waterless shampoos? Like how they work and their main ingedients that make it so.
So-called "Waterless" or rinse-free shampoos are simply much more dilute versions of "regular" shampoos. They work exactly the same way as regular shampoos do. Bobzchemist 06:07, 18 February 2007 (UTC)
Another version of the waterless shampoo is an absorbent powder such as Talc or cornstarch, which is rubbed through to remove excess grease and oil. They're not popular as they are messy, don't always brush out clean, and are of limited effectiveness. Valueaddedwater 20:38, 30 September 2007 (UTC)
I marked this article for cleanup because it was generally terrible. There was much POV ranting about natural shampoos without the harmful detergents... you know, the ones that actually clean your hair in the first place :
so I rewrote a bit, commented out some crap, and am working on trying to add some more information
I cleaned up a lot of the ranting. The previous guy had a problem with the shampoo industry, I think this article should cover:

I'm curious as to the source of saying the detergents/surfactants used in modern shampoo are considered to be synthetic? How do you define whether its a natural or synthetic surfactant? —Preceding unsigned comment added by Darconas ( talk • contribs)
All detergents are synthetic, but they are called synthetic to differentiate them from soaps, which are made from animal or vegetable fat. Bobzchemist 06:10, 18 February 2007 (UTC)
I agree with the unsigned poster above: the chemistry behind two-in-one shampoos (of which there seem to be more than one kind, see [1], [2]) should be covered here in detail. -- Karada 14:58, 31 March 2006 (UTC)
Isn't kind of strange that so far there has been no vandalism to the page 64.12.116.5
No I'm pretty Sure that's a good thing.
I remember learning that the purpose of shampoo was to clean the scalp, not hair. This is the reason why you are supposed to massage the shampoo into your head, to clean all the dead skin cells. 71.250.19.117 13:21, 14 April 2006 (UTC)
I removed the Dimethicone section from the Ingredients heading, as Dimethicone is used in conditioners and there is a separate article about that. Carax 04:51, 16 April 2006 (UTC)
I was watching the Channel 4/PBS documentary " 1900 House" DVD and they claim that shampoo as we know it was invented in 1950 (!) -- which seems incredibly late. As this Wiki entry states, shaved soap and hot water passed for hair washing for quite some time. The particpants in 1900 House made shampoo according to period recipes but complained it was nothing like what we know as shampoo (as it left quite a bit of residue and left the hair in terrible condition). (They later tried another period recipe containing only egg yolks and lemon! yuck!)
Does anyone have any history on modern shampoo? Certainly movie stars in the 1940s would not have used dissolved soap shavings, would they? Modern shampoo would have to be linked with the creation of sodium lauryl sulfate. Navstar 18:40, 8 June 2006 (UTC)
Synthetic detergents started to be commercially available in the 1930's. So a 1940's screen star would have had the luxury, a silent movie star wouldn't have been so lucky Valueaddedwater ( talk) 18:59, 29 April 2008 (UTC)
I agree amino acids and nucleic acis would provide very little benefit to hair. And whole protein molecules would be too large to enter the cuticle. But the section seems to want to argue about *permanently* bonding new amino acids to hair, which of course isn't going to happen in dead cells. But I haven't seen any conditioner or shampoo marketed as permanently improving hair. Adding hydrolized protein bits that are cationically charged will help temporarily improve the look of damaged or fine fine (until its washed again). -- 68.103.154.140 17:04, 27 June 2006 (UTC)
is it really good at all to use? has the details ... I would love to see this content cited, as well as rebutted in the content of this article.
I spotted 3 basic chemical errors in the first paragraph of that link. Its not, shall we say, wikipedia standard as regards a) accuracy, or b) POV Valueaddedwater ( talk) 19:06, 29 April 2008 (UTC)
can somebody put in a little snippet about natural vs. organic? to the best of my knowledge, organic is a term used by the FDA and hence, there is no such thing as an organic shampoo (or at least it is in washington state)
i dont want to do it at the risk of sounding like a 12 year old's run on sentence, but from working in a salon, i can give you this link that very breifly covers it [3]
ps, thanks to whoever deleted the whole section about different brands. considering theres thousands upon thousands, that wouldve been an effort in vain...
Hazzayoungn 10:05, 23 December 2006 (UTC)
I think this article lacks criticism. There are alot of shampoos which actually is hazardous to either/both the environment or/and humans in either small or big ways.
PS: This line sounds like commercial to me.
Feel free to write a section on the controversey. Personally, I feel that the above statement has no basis in fact. There are many people that make this claim - they all turn out to be selling something. Bobzchemist 03:58, 16 January 2007 (UTC)
The biodegradeability issue hasn't been relevant since the 60's when the use of phosphate based, non biodegradeable detergents was banned, due to the outflow of sewage works being a wall of foam. Microbial preservation of liquid detergent products is always an issue, so once it has been used by the consumer, and hits the sewers, its bug food Valueaddedwater 20:43, 30 September 2007 (UTC)
Shampoo formulations seek to maximize the following qualities:
- Easy rinsing
- Good finish after washing hair
- Minimal skin/ eye irritation
- No damage to hair
- Feels thick and/or creamy
- Smells good
- Low toxicity
- Good biodegradability
- slightly acidic pH, since a basic environment weakens the hair by breaking the disulfide bonds in hair keratin.
Many shampoos are pearlescent. This effect is achieved by addition of tiny flakes of suitable materials, eg. glycol distearate (a wax).

…like those used for pets. What exactly are these? — Nahum Reduta 12:00, 14 April 2007 (UTC)
This section seems pretty useless.
Hi:
I think the article could also address shampoo as a class of soap. My understanding is that shampoo is a soap with a different vehicle, but it's basically a soap. Ie washing your hair with a bar of soap is no different.
(Signed a man with a beard whose idiot friend gave him very expensive shaving soap for his birthday -- WTF?)
Both shampoo and a true soap are detergents, but thats where the similarity ends.
Using soap to shave with is not the same as washing hair with it, as it doesn't matter if the hair above the skin surface is damaged before shaving, as you're cutting it off anyway.
If you are into the yul brinner look, I suppose washing your scalp with a bar of soap would be similar Valueaddedwater 20:47, 30 September 2007 (UTC)

Homemade shampoos are better for your hair and much cheaper.

Solid shampoos or shampoo bars use as their surfactants soaps and/or other surfactants conveniently formulated as solids. They have the advantage of being spill-proof, and the disadvantage of being slowly applied, needing to be dissolved in use.
Does anyone know what the difference is, apart from scent, between these two types of shampoo? A friend asked me recently, and I was surprised that Wikipedia didn't mention it. TheDarkFlame ( talk) 01:53, 20 March 2009 (UTC)
I removed the section about animals skin being thinner than humans and thus requiring milder shampoos because while quite possibly true, it wasn't sourced.
This section is terribly organized and should be arranged into coherent paragraphs. —Preceding unsigned comment added by 67.243.140.144 ( talk) 06:21, 14 July 2010 (UTC)
The animal shampoo section claims that differences in skin structure require special shampoo formulations for animals. This seems unlikely to be true and requires a reference. DrPD ( talk) 01:55, 1 February 2010 (UTC)
I'm wondering if the shampoo free ("no poo") movement might not merit some inclusion in this article along with other criticisms of shampoo.
By way of proof of notability/verifiability, I offer the following: this from the Boston Phoenix and this article from Salon.com. There are more out there, but these seem to be the most Wikipedia ... friendly. 70.94.242.178 ( talk) 06:45, 27 February 2010 (UTC)

Fn28 links to ch10 of Packing for Mars. But the book in ch10 states:
> Once a set of clothes becomes saturated and oil starts to build up on the skin, what’s the end point? Does uncleansed skin grow ever greasier as the days pass? It does not. According to the Soviet research, the skin halts its production of sebum* after five to seven days of not bathing and not changing one’s increasingly well-greased clothing. Only when the person changes his shirt or takes a shower do the sebaceous glands get back to work. Skin seems happiest with a five-day buildup of oils. Listen to Professor Elaine Larson, editor of the American Journal of Infection Control, talking about the stratum corneum, the outermost layer of human skin: “This horny layer has been compared to a wall of bricks (corneocytes) and mortar (lipids)” and helps “maintain the hydration, pliability, and barrier effectiveness of the skin.”
This seems to say the exact opposite of what the article text is claiming Roach wrote in her book. Could someone clarify this? -- Gwern (contribs) 01:58 3 May 2013 (GMT)
This story got quite a lot of coverage: [4], [5], [6]. Article obviously needs a section on advertising. Martinevans123 ( talk) 22:30, 6 February 2015 (UTC)
To my knowledge there is no mechanism in the skin or sebaceous glands for identifying oil on the skin or the lack thereof and reacting to it by producing more oil. I have searched the internet for proof of these claims but cannot find any. The "nopoo" section claims that dermatologist Michelle Hanjani asserst that a reduction in shampoo use will cause sebaceous glands to produce at a slower rate but the provided citation is a story piece from NPR with no citations of its own.
Hi, According to the article, Josef Baumann-Widmer introduced the first liquid shampoo in 1900, but in this source: https://www.rausch.ch/ueber-uns/geschichte.html it says he was born in 1902. Moreover, the first person to develop a shampoo seems to be Schwarzkopf, who developed the first shampoo powder (around 1903) and started selling it abroad. — Preceding unsigned comment added by 2A02:A311:4349:2E00:886E:D9C0:97CB:2A7C ( talk) 19:01, 27 April 2022 (UTC)

I'm calling it non-notable, and I will delete it unless someone objects and can show a citation from more than one company. Bobzchemist 21:17, 9 February 2007 (UTC)
There have been various commercial solid shampoos going back at least to Neutrogena Solid Soap Shampoo ca. 1970. (That's not counting soaps which were labeled as for shampooing among other uses, e.g. "Lifebuoy Shower, Bath and Shampoo Soap", as it was called for a while.) There are also recipes for homemade shampoo bars at soapmaking sites. There was a brand of shampoo bar from Fla. a few years ago and since discontinued based on disodium lauryl sulfosuccinate. If somebody cited brands now, those would be advertisements. --robgood@bestweb.net 216.179.1.232 ( talk) 22:55, 24 March 2009 (UTC)
A lot of hair care products are adversted as containing 'Pro-Vitamins'. My understanding was that a pro-vitamin was something the body (usually the liver) could convert into a vitamin when required. For example, betacarotene would be considered 'pro- vitamin A.
Is there any benefit in adding 'pro-vitamins' to hair care products, or is this just impressive-sounding marketing hype? Are there any good refernces on this subject? -- PJF (talk) 04:23, 27 Feb 2005 (UTC)
Panthenol does have an ability to bind electrostatically to the hair shaft to give a conditioning effect that can be percieved by the user in the same way that quaternery based conditioners (The same as used in fabric softener)do. If anyone says that they are "Feeding the hair" this is guff, as the hair shaft is dead (Only the bulb under the skin is actually alive). Rememeber that this is a cosmetic product, so the only effects you will get are, by definition, cosmetic Valueaddedwater 20:35, 30 September 2007 (UTC)
Does anyone have any information about waterless shampoos? Like how they work and their main ingedients that make it so.
So-called "Waterless" or rinse-free shampoos are simply much more dilute versions of "regular" shampoos. They work exactly the same way as regular shampoos do. Bobzchemist 06:07, 18 February 2007 (UTC)
Another version of the waterless shampoo is an absorbent powder such as Talc or cornstarch, which is rubbed through to remove excess grease and oil. They're not popular as they are messy, don't always brush out clean, and are of limited effectiveness. Valueaddedwater 20:38, 30 September 2007 (UTC)
I marked this article for cleanup because it was generally terrible. There was much POV ranting about natural shampoos without the harmful detergents... you know, the ones that actually clean your hair in the first place :
so I rewrote a bit, commented out some crap, and am working on trying to add some more information
I cleaned up a lot of the ranting. The previous guy had a problem with the shampoo industry, I think this article should cover:

I'm curious as to the source of saying the detergents/surfactants used in modern shampoo are considered to be synthetic? How do you define whether its a natural or synthetic surfactant? —Preceding unsigned comment added by Darconas ( talk • contribs)
All detergents are synthetic, but they are called synthetic to differentiate them from soaps, which are made from animal or vegetable fat. Bobzchemist 06:10, 18 February 2007 (UTC)
I agree with the unsigned poster above: the chemistry behind two-in-one shampoos (of which there seem to be more than one kind, see [1], [2]) should be covered here in detail. -- Karada 14:58, 31 March 2006 (UTC)
Isn't kind of strange that so far there has been no vandalism to the page 64.12.116.5
No I'm pretty Sure that's a good thing.
I remember learning that the purpose of shampoo was to clean the scalp, not hair. This is the reason why you are supposed to massage the shampoo into your head, to clean all the dead skin cells. 71.250.19.117 13:21, 14 April 2006 (UTC)
I removed the Dimethicone section from the Ingredients heading, as Dimethicone is used in conditioners and there is a separate article about that. Carax 04:51, 16 April 2006 (UTC)
I was watching the Channel 4/PBS documentary " 1900 House" DVD and they claim that shampoo as we know it was invented in 1950 (!) -- which seems incredibly late. As this Wiki entry states, shaved soap and hot water passed for hair washing for quite some time. The particpants in 1900 House made shampoo according to period recipes but complained it was nothing like what we know as shampoo (as it left quite a bit of residue and left the hair in terrible condition). (They later tried another period recipe containing only egg yolks and lemon! yuck!)
Does anyone have any history on modern shampoo? Certainly movie stars in the 1940s would not have used dissolved soap shavings, would they? Modern shampoo would have to be linked with the creation of sodium lauryl sulfate. Navstar 18:40, 8 June 2006 (UTC)
Synthetic detergents started to be commercially available in the 1930's. So a 1940's screen star would have had the luxury, a silent movie star wouldn't have been so lucky Valueaddedwater ( talk) 18:59, 29 April 2008 (UTC)
I agree amino acids and nucleic acis would provide very little benefit to hair. And whole protein molecules would be too large to enter the cuticle. But the section seems to want to argue about *permanently* bonding new amino acids to hair, which of course isn't going to happen in dead cells. But I haven't seen any conditioner or shampoo marketed as permanently improving hair. Adding hydrolized protein bits that are cationically charged will help temporarily improve the look of damaged or fine fine (until its washed again). -- 68.103.154.140 17:04, 27 June 2006 (UTC)
is it really good at all to use? has the details ... I would love to see this content cited, as well as rebutted in the content of this article.
I spotted 3 basic chemical errors in the first paragraph of that link. Its not, shall we say, wikipedia standard as regards a) accuracy, or b) POV Valueaddedwater ( talk) 19:06, 29 April 2008 (UTC)
can somebody put in a little snippet about natural vs. organic? to the best of my knowledge, organic is a term used by the FDA and hence, there is no such thing as an organic shampoo (or at least it is in washington state)
i dont want to do it at the risk of sounding like a 12 year old's run on sentence, but from working in a salon, i can give you this link that very breifly covers it [3]
ps, thanks to whoever deleted the whole section about different brands. considering theres thousands upon thousands, that wouldve been an effort in vain...

I think this article lacks criticism. There are alot of shampoos which actually is hazardous to either/both the environment or/and humans in either small or big ways.
PS: This line sounds like commercial to me.
Feel free to write a section on the controversey. Personally, I feel that the above statement has no basis in fact. There are many people that make this claim - they all turn out to be selling something. Bobzchemist 03:58, 16 January 2007 (UTC)
The biodegradeability issue hasn't been relevant since the 60's when the use of phosphate based, non biodegradeable detergents was banned, due to the outflow of sewage works being a wall of foam. Microbial preservation of liquid detergent products is always an issue, so once it has been used by the consumer, and hits the sewers, its bug food Valueaddedwater 20:43, 30 September 2007 (UTC)
Shampoo formulations seek to maximize the following qualities:
- Easy rinsing
- Good finish after washing hair
- Minimal skin/ eye irritation
- No damage to hair
- Feels thick and/or creamy
- Smells good
- Low toxicity
- Good biodegradability
- slightly acidic pH, since a basic environment weakens the hair by breaking the disulfide bonds in hair keratin.
Many shampoos are pearlescent. This effect is achieved by addition of tiny flakes of suitable materials, eg. glycol distearate (a wax).

…like those used for pets. What exactly are these? — Nahum Reduta 12:00, 14 April 2007 (UTC)
This section seems pretty useless.
Hi:
I think the article could also address shampoo as a class of soap. My understanding is that shampoo is a soap with a different vehicle, but it's basically a soap. Ie washing your hair with a bar of soap is no different.
(Signed a man with a beard whose idiot friend gave him very expensive shaving soap for his birthday -- WTF?)
Both shampoo and a true soap are detergents, but thats where the similarity ends.
Using soap to shave with is not the same as washing hair with it, as it doesn't matter if the hair above the skin surface is damaged before shaving, as you're cutting it off anyway.
If you are into the yul brinner look, I suppose washing your scalp with a bar of soap would be similar Valueaddedwater 20:47, 30 September 2007 (UTC)

Solid shampoos or shampoo bars use as their surfactants soaps and/or other surfactants conveniently formulated as solids. They have the advantage of being spill-proof, and the disadvantage of being slowly applied, needing to be dissolved in use.
Does anyone know what the difference is, apart from scent, between these two types of shampoo? A friend asked me recently, and I was surprised that Wikipedia didn't mention it. TheDarkFlame ( talk) 01:53, 20 March 2009 (UTC)

Fn28 links to ch10 of Packing for Mars. But the book in ch10 states:
> Once a set of clothes becomes saturated and oil starts to build up on the skin, what’s the end point? Does uncleansed skin grow ever greasier as the days pass? It does not. According to the Soviet research, the skin halts its production of sebum* after five to seven days of not bathing and not changing one’s increasingly well-greased clothing. Only when the person changes his shirt or takes a shower do the sebaceous glands get back to work. Skin seems happiest with a five-day buildup of oils. Listen to Professor Elaine Larson, editor of the American Journal of Infection Control, talking about the stratum corneum, the outermost layer of human skin: “This horny layer has been compared to a wall of bricks (corneocytes) and mortar (lipids)” and helps “maintain the hydration, pliability, and barrier effectiveness of the skin.”
This seems to say the exact opposite of what the article text is claiming Roach wrote in her book. Could someone clarify this? -- Gwern (contribs) 01:58 3 May 2013 (GMT)

To my knowledge there is no mechanism in the skin or sebaceous glands for identifying oil on the skin or the lack thereof and reacting to it by producing more oil. I have searched the internet for proof of these claims but cannot find any. The "nopoo" section claims that dermatologist Michelle Hanjani asserst that a reduction in shampoo use will cause sebaceous glands to produce at a slower rate but the provided citation is a story piece from NPR with no citations of its own.
Hi, According to the article, Josef Baumann-Widmer introduced the first liquid shampoo in 1900, but in this source: https://www.rausch.ch/ueber-uns/geschichte.html it says he was born in 1902. Moreover, the first person to develop a shampoo seems to be Schwarzkopf, who developed the first shampoo powder (around 1903) and started selling it abroad. — Preceding unsigned comment added by 2A02:A311:4349:2E00:886E:D9C0:97CB:2A7C ( talk) 19:01, 27 April 2022 (UTC)
