Hair Cleaning - Shampoo Prevent Hair Thinning
 To combat this appearance of “dirty” hair, and to remove actual dirt and other contaminants and external substances like sweat, the hair may be washed.

| Shampoo is helped by warm temperature water, which helps open the cuticle of the hair and release any oils or other substances beneath. Pure water has a pH of 7, and when shampoo has removed the slightly acidic sebum from the hair, the pH on the surface of the scalp is raised. Freshly shampooed hair can feel tangled or rough, and hair which is left to dry after a shampoo only can be excessively dry and coarse.

To smooth the hair, Conditioner is often used. Conditioners may employ ingredients of an acidic nature to balance the hair and scalp pH. Many modern conditioners also contain plant oils or synthetic ingredients such as plastics to coat the hair shaft and smooth it out. Acidic rinses or chemical conditioners can help with hair detangling and manageability, which helps prevent damage.
The sebaceous glands increase or reduce their secretions in order to maintain proper skin protection and pH. When the skin is regularly stripped of its natural sebum, the sebaceous glands respond with an overproduction. People observe that they “must” wash their hair, for example, once every other day, otherwise their hair becomes oily; however, their sebaceous glands have simply adapted to their hygienic cycle. Changes to the hygienic cycle result in changes to sebum secretion.
Modern shampoos and conditioners are not necessary to maintain clean and healthy hair, and indeed, many cultures do not have these products at all. Different methods are available for those people who wish to return to this “natural” hair state, where healthy hair can be maintained with scalp massage, water-only washes, or using cleaning agents very rarely.
Natural baseline sebum secretion varies by individual, and returning the scalp to this state takes time. This process may often include using cleaning agents, but is generally geared towards leaving the sebum on the scalp and hair for as long as possible to reacclimatize the scalp to producing less sebum. This process may not be for everyone, as some who try this method never reach a point where they feel their hair can be clean for any extended period of time without washing with conventional shampoo.
Using cold water as a final rinse can help close the scales of the cuticle, and can help constrict the openings of the sebaceous glands to help moderate sebum production.
There are various ways to shampoo hair, and selection of a method is determined by one's hair type and available resources.
The most common method of hair washing is shampooing followed by conditioning. If one is a daily hair washer, then a repeating of the hair shampoo application may not be necessary. However, if one waits a day or more between hair washings, then the first shampoo may only break up the surface tension of sebum, and a second shampoo application to the scalp hair may be necessary to thoroughly remove the sebum. The second application is not necessary to apply to any hair length.
To help lift any scaly skin, detritis, and sebum, especially for those who suffer from scalp skin ailments, very gently scratching the surface of the skin with a small fine toothed comb may help to loosen and lift grime and dead skin cells before a hair wash, helping to have a cleaner scalp skin after a hair wash.
Microfiber towels that help absorb the water from hair faster than conventional towels are available on the market. These are particularly helpful for those with very thick hair that may otherwise take a while to dry, especially if air drying.
Washing hair with shampoo and conditioner should used moderately. Washing with shampoo and conditioner more than 3 times a week may dry hair, making it "frizzy."
