It works. From the very first use that is. I have been using it for a month or more and I have noticed reduced hair fall with each use. I really don’t know how it is so effective to show results in one or two uses, but it does. There is less hair fall during the process of washing my hair too and I actually checked it by changing my shampoo with the usual one for my next wash and I could see a lot of hair in my bath tub. 😐 So, I have arrived at the conclusion that this shampoo is indeed miraculous for falling hair.
