Feisal shares that “washing with water alone is like taking a shower without soap—great as a quick refresh, but probably not ideal for most of us to do all of the time. Water will only help rinse the hair's surface of dust and debris, but will not do much else and especially won't 'wash' your hair.”

"For someone with healthy hair and low scalp-oil production, skipping shampoo is not really an issue. However, if you have an oily scalp, dandruff or psoriasis in the scalp, you may need to use shampoos to effectively remove oil and flakes," Zeichner says.
What Is the No-Poo Method? The no-poo method is a hair-cleansing technique that removes shampoo from the equation, says Geeta Yadav, MD, a dermatologist in Toronto.

"The average individual can typically go 2 to 3 days without shampooing their hair. However, if your hair is visibly oily, you may not want to wait that long," she says. "Usually, you can go longer without washing your hair when your hair is styled up, but no one should ever go more than 14 days."
Shampoo as we know it today has only existed for about 100 years. Prior to 1903, the act of hair washing ranged from a head massage with fragrant oils to boiling pieces of “shaved soap” bars in water. There are a range of early methods, however let's focus on the past hundred years or so.

The first signs of soap appeared in the 18th century
In Brighton, England, an Indian man, Sake Dean Mahomed, opened baths dedicated to shampoo. Everyone went there to get their hair washed and to have their hair massaged with vegetable oil. At the end of the 18th century, 'shampoo' arrived in Europe.
Originally, soap and shampoo were very similar products; both containing the same naturally derived surfactants, a type of detergent. Modern shampoo as it is known today was first introduced in the 1930s with Drene, the first shampoo using synthetic surfactants instead of soap.
With a hose connected to a gas stove's hot air outlet, a woman would attach the other end of the hose to a cap on her head, and the hot air heated and dried her hair. There was even an escape valve for steam, so the woman did not end up cooking her head!
