I am planning to buy Kevis Hair Rejuvenation but I want to know that is it just a snake oil? I have read one of the reviews which stated that this product can even increase the hair fall. The product cost around $700 and it is not worth it. It was also written that no one is there to listen to your complains once the product is sold out. As I have not got good reviews about the product I donât think so that I should try it, but I also think that I should take last opinion. So I want to know what you think about kevis hair rejuvenation.
