Could shampoo be a thing of the past? Millions of us spend a lot of time and money on it, but is it necessary?
Shampoo sales have gone down a lot in the UK recently as more people are changing their hair-washing habits. A recent study by Nielsen, a consumer analyst company, said, “People are working at home, so they are using less shampoo less frequently than before.” The ecosalon.com website said shampooing regularly may be the reason why hair gets so greasy. Shampoo makes the skin of the head dry, so the head produces more oil, which you then shampoo again to remove. The site said, “By shampooing less often, your head skin naturally reduces its production of oil.”
However, many people say shampoo is good for the hair. Mark Coray, a former president of the National Hairdressers’ Federation in the UK, says there is no benefit to not washing your hair. He said, “Shampoo will not harm the head skin. The ingredients(成分) in shampoo help the hair to look so smooth. The oil may build up, so it starts to look like it is shiny, but it will not self-clean.” A hair loss clinic in London, the Belgravia Centre, said, “Washing your hair with clean water only is not going to be very effective after certain activities that make the head skin sweaty, such as exercising or using a sauna(桑拿浴).” It added, “Washing your hair with clean water only will also not remove bacteria(细菌) or clean the excess oil from your head skin if you have greasy hair.”
