Vidal Sassoon shampoo comes in 3 categories :1) Fine or thin
2) Normal 3) Dry or colour treated hair.It is advisable to choose the shampoo depending on the type of your hair.This brand in particular has not only helped me but also helped my patients in maintaining a smooth & silky hair texture with practically no hair damage.It has a well balanced ph which is important for better quality hair.I have been using Vidal Sassoon for 4 yrs now & have never had complaints such as hair fall, split ends or thinning of hair.However, it is advisable to use this shampoo not more than 3 times a week.Any shampoo if used everyday is likely to be harsh on the hair unless it is a very mild one like baby shampoos.The bottom line remains- V.S. has remained my favourite shampoo & given a chance I would recommend it to everybody.
