Could shampoo be a thing of the [passed / past] ? Millions of us spend a lot of time and money [on / in] it, but is it necessary? Shampoo sales have [going / gone] down a lot in the UK [recent / recently] as more people are changing their hair-washing [habits / habitat] . A recent study by Nielsen, a consumer analyst company, said: "People are working [from / for] home…and fewer people are smoking, so [they] are using [less / fewer] shampoo less frequently than before."

However, many people say shampoo is good for [a / the] hair. Mark Coray, a former president of the National Hairdressers' Federation [in / at] the UK, says there is no benefit to [no / not] washing your hair. He said: "Shampoo is not abrasive [nor / or] harsh to the scalp….The ingredients in shampoo help the hair to look [such / so] glossy….The hair's oil may build [up / on] so it starts to look like it is [shiny / shine] ...but it will not self-clean." A hair loss clinic in London, The Belgravia Centre, said: "Rinsing your hair is not going to [be / do] very effective after certain activities that make the scalp sweaty, such [was / as] exercising or using a sauna." It added: "Rinsing will also not remove bacteria or clean the excess oil from your scalp if you have [grease / greasy] hair."
