There are thousands of shampoos on the market, many which are touted to combat hairloss. It is indeed difficult to sieve out the ones that would really work for you unless you try it on your own.
But this entails money like what I did, trying one brand of shampoo to the other, all those shampoos which are supposed to fix hair loss, but all to no success. Often, the branding agents tout the shampoo like though it is the best, but sad to say it is not.
For hair loss sufferers suffering from oily scalp too like me and trying to find a shampoo which could combat oily scalp, dandruff and promote hair loss, I feel that there is no such shampoo in the market which could have such dual functions. I want to cure my oily scalp but at the same time want to grow some hair.. but there is no such shampoo till now that I tried for 2 years which could do that. It is a matter of compromise, depends on what you want to deal: oily scalp or hair loss.
