How Often Should You Shampoo Your Hair ????

Although daily hair care implies daily shampooing, women who are lucky enough to have normal hair — that is, not too dry or too oily — achieve the best results when they wash their hair only every other day. 
Washing hair too often can over dry the hair from the astringents in most shampoos; it can also cause an overproduction of sebum, which makes hair extra oily. However, if your hair tends to be oily, you probably need to shampoo every day. On the other side of the spectrum, dry hair is often most manageable and soft when you wait at least two or three days between shampoos.
