I have used two bottles of regen and I havent seen any significant growth or thickness in my hair.
Regen can be used as normal hair product because it do help in reducing the dandruff but it cant grow hair.I think it is highly advertised product in internet.see their web page they are calming a lot of thing but I just surprised it is not certified by any agencies in India or aboard.Also price is very high but if this can grow hair then price is no matter.If anyone wants to use regen then my advice is just dont use it for hair loss.Also while going through other review in mouthshut I smell the cheap marketing for this useless product.
Finally its upto you if u really want to give regen a chance please go for it but this will only end up in waste of ur hard earned money.
