No poo
"No poo"〔 (no shampoo) is a collective term for methods of washing hair without commercial shampoo.〔 == Theory == The first synthetic shampoos were introduced in the 1930s,〔 with daily shampooing becoming the norm in the US by the 1970s and 1980s.〔 Proponents of "no poo"-practices believe that shampoo removes the natural oils (sebum) produced by the scalp—causing the scalp to produce more oil to compensate.〔〔 They also believe that regular shampooing causes a "vicious cycle" to develop as it becomes necessary to shampoo regularly to compensate for the excess oils produced by the scalp (which are produced in response to being stripped from the scalp by the previous shampooing).〔 According to some dermatologists, a gradual reduction in shampoo use will cause the sebaceous glands to produce at a slower rate, resulting in less oil on the scalp and hair.〔 In the 2010 book ''Packing for Mars'', Soviet research is quoted as "the skin halts its production of sebum—after five to seven days of not bathing...."〔 The time taken to break the cycle after adopting "no poo"-practices varies, however a "two- to six-week period" is typical.〔
