Shampoo is a common hair care product used for the removal of oils, dirt, skin particles, dandruff, environmental pollutants and other contaminant particles that gradually build up in hair. The goal is to remove the unwanted build-up without stripping out so much as to make hair unmanageable. This page meets Wikipedias criteria for speedy deletion. ...

Shampoo, when lathered with water, is a surfactant, which, while cleaning the hair and scalp, can remove the natural oils (sebum) which lubricate the hair shaft. Surfactants are wetting agents that lower the surface tension of a liquid, allowing easier spreading, and lower the interfacial tension between two liquids. ... The sebaceous glands are glands found in the skin of mammals. ...

Shampooing is frequently followed by conditioners which increase the ease of combing and styling. Hair conditioners, sometimes called cream rinse, are often used in hair care alongside shampoo, to improve the texture and appearance of human hair. ...



The word shampoo in English usage dates back to 1762, with the meaning "to massage". The word was a loan from Anglo-Indian shampoo, in turn from Hindi chāmpo (चाँपो /tʃãːpoː/), imperative of chāmpnā (चाँपना /tʃãːpnaː/), "to smear, knead the muscles, massage". It itself comes from Sanskrit/Hindi word "champā" (चम्पा /tʃəmpaː/), the flowers of the plant Michelia champaca which have traditionally been used to make fragrant hair-oil.

The term and service was introduced by a Sake Dean Mahomed, who opened a shampooing bath known as Mahomed's Indian Vapour Baths in Brighton, England in 1759. His baths were like Turkish baths where clients received an Indian treatment of champi (shampooing) or therapeutic massage. His service was appreciated; he received the high accolade of being appointed ‘Shampooing Surgeon’ to both George IV and William IV.

How shampoo works

Shampoo cleans by stripping sebum from the hair. Sebum is an oil secreted by hair follicles that is readily absorbed by the strands of hair, and forms a protective layer. Sebum protects the protein structure of hair from damage, but this protection comes at a cost. It tends to collect dirt, styling products and scalp flakes. Surfactants strip the sebum from the hair shafts and thereby remove the dirt attached to it. The sebaceous glands are glands found in the skin of mammals. ... A hair follicle is part of the skin that grows hair by packing old cells together. ...

While both soaps and shampoos contain surfactants, soap bonds to oils with such affinity that it removes too much if used on hair. Shampoo uses a different class of surfactants balanced to avoid removing too much oil from the hair. Surfactants, also known as wetting agents, lower the surface tension of a liquid, allowing easier spreading. ...

The chemical mechanisms that underlie hair cleansing are similar to that of traditional soap. Undamaged hair has a hydrophobic surface to which skin lipids such as sebum stick, but water is initially repelled. The lipids do not come off easily when the hair is rinsed with plain water. Shampoo applied to wet hair is absorbed into the oil/hair interfaces. The anionic surfactants substantially reduce the interfacial surface tension and allow for the removal of the sebum from the hair shaft. The non-polar oily materials on the hair shaft are solubilised into the surfactant micelle structures of the shampoo and are removed during rinsing. There is also considerable removal through a surfactant and oil "roll up" effect. The foamy effect achieved by massaging shampoo into the hair is purely aesthetic. The foam itself does nothing to clean the hair and is a byproduct of the ingredients. In chemistry, hydrophobic or lipophilic species, or hydrophobes, tend to be electrically neutral and nonpolar, and thus prefer other neutral and nonpolar solvents or molecular environments. ... Figure 1: Basic lipid structure. ... In chemistry, an anionic species is one that contains a full negative charge. ... Surfactants, also known as wetting agents, lower the surface tension of a liquid, allowing easier spreading. ... Schematic of a micelle. ...


Shampoo formulations seek to maximize the following qualities:

Many shampoos are pearlescent. This effect is achieved by addition of tiny flakes of suitable materials, eg. glycol distearate, chemically derived from stearic acid, which may have either animal or vegetable origins.

Ingredient claims

In the USA, the Food and Drug Administration (FDA) mandates that shampoo containers accurately list ingredients. The government further regulates what shampoo manufacturers can and cannot claim as any associated benefit. Shampoo producers often use these regulations to challenge marketing claims made by competitors, helping to enforce these regulations. While the claims may be substantiated however, the testing methods and details of such claims are not as straightforward. For example, many products are purported to protect hair from damage due to ultraviolet radiation. While the ingredient responsible for this protection does block UV, it is not present in a high enough concentration to be effective. Shampoos made for treating medical conditions such as dandruff are regulated as OTC drugs.[2] FDA logo The Food and Drug Administration (FDA) is an agency of the United States Department of Health and Human Services and is responsible for regulating food, dietary supplements, drugs, biological medical products, blood products, medical devices, radiation-emitting devices, veterinary products, and cosmetics in the United States. ...

Vitamins and Amino Acids

The effectiveness of vitamins, amino acids and "pro-vitamins" to shampoo is also largely debatable. Vitamins and amino acids are the building blocks of proteins and enzymes within the body. While vitamins may be able to penetrate cells through the skin, amino acids and proteins are too large to enter a cell outside the bloodstream, and they can have no effect on dead tissue. Proteins are constructed from amino acids following an RNA blueprint inside the cell. A strand of hair is a long protein chain continually being added to at the root. The only way for an amino acid to be of any use is to be intentionally bound to other amino acids in a specific fashion by a living cell. Hair is not alive, and there is no possibility for an amino acid or protein to have any permanent effect on the health of the strand. Retinol (Vitamin A) For the record label, see Vitamin Records A vitamin is an organic compound required in tiny amounts for essential metabolic reactions in a living organism. ...

The case for vitamins is not as well understood. Some have demonstrated a moderate effectiveness in improving the health of skin,[3] but most likely the benefit is derived from the effect of vitamins on living cells below the epidermis. Extending this benefit to hair, the vitamins and minerals could improve the health of new hair growth, but the benefit to existing hair is unsubstantiated. However, the physical properties of some vitamins (like vitamin E oil or panthenol) would have a temporary cosmetic effect on the hair shaft while not having any bioactivity. Tocopherol, or Vitamin E, is a fat-soluble vitamin in eight forms that is an important antioxidant. ... Panthenol is the alcohol analog of pantothenic acid (vitamin B5), and is thus the provitamin of B5. ...

Shampoo for infants is formulated so that it is the same pH level as the eye, thus less irritating if it were to get into the eyes. Most contain sodium lauryl sulfate and/or sodium laureth sulfate, the mildest surfactant of the sulfate family. Alternatively, infant shampoos may be formulated using other classes of surfactants, most notably non-ionics which are much milder than any charged anionics used.

Shampoo for animals (such as for dogs or cats) should be formulated especially for them, as their skin has fewer cell layers than human skin. Cats' skin is 2-3 cell layers thick, while dogs' skin is 3-5 layers. Human skin, by contrast, is 10-15 cell layers thick. This is a clear example of why one should never use even something as mild as baby shampoo on a cat, dog, or other pet.

Shampoo intended for animals may contain insecticides or other medications for treatment of skin conditions or parasite infestations such as fleas or mange. These must never be used on humans! It is equally important to note that while some human shampoos may be harmless when used on animals, any haircare products that contain active ingredients/drugs (such as zinc in antidandruff shampoos) are potentially toxic when ingested by animals. Special care must be taken not to use those products on pets. Cats are at particular risk due to their instinctive method of grooming their fur with their tongues.

Traditional Shampoos


Early shampoos used in Indonesia were made from the husk and straw (merang) of rice. The husks and straws were burned into ash, and the ashes (which have alkaline properties) are mixed with water to form lather. The ashes and lather were scrubbed into the hair and rinsed out, leaving the hair clean, but very dry. After shampooing, Indonesians applied coconut oil to remoisten the hair.[4] The term husk is mostly used to refer to the leafy outer covering of an ear of maize (corn) as it grows on the plant. ...
