Could shampoo be a thing the past? Millions us spend a lot time and money it, but is it necessary? Shampoo sales have gone down a lot the UK recently as more people are changing their hair-washing habits. A recent study Nielsen, a consumer analyst company, said: "People are working home…and fewer people are smoking, so [they] are using less shampoo less frequently than before." The ecosalon.com website said shampooing regularly may be the reason hair gets so greasy. Shampoo makes the scalp dry, so the head produces more oil, which you then shampoo again to remove. The site said: " shampooing less often, your scalp naturally reduces its production [oil]."
However, many people say shampoo is good the hair. Mark Coray, a former president the National Hairdressers' Federation the UK, says there is no benefit to not washing your hair. He said: "Shampoo is not abrasive or harsh to the scalp….The ingredients shampoo help the hair to look so [glossy]….The hair's oil may build so it starts to look like it is shiny...but it will not self-clean." A hair loss clinic London, The Belgravia Centre, said: "Rinsing your hair is not going to be very effective certain activities that make the scalp sweaty, such as exercising or using a sauna." It added: "Rinsing will also not remove bacteria or clean the excess oil your scalp if you have greasy hair."
