I have hair fall problem, and I use Nizoral shampoo, and it is just fine for me. Nonetheless, my mom bought a bottle of revita shampoo this time, saying its quite effective for hair fall. As per the ingredients mentioned on the bottle of revita shampoo, I am quite contended about its effectiveness, however, I would like to know about its directions to use, by someone, who has already used this product before. Would it be just fine if I use this shampoo twice a day? Thanks.
