My hair started thinning last year, i tried many products but without positive results. After try this product, my hair seems alive, more vibrant with less breakage now. I am on my third bottle now and I will buy more. For those of you out there looking for a full mane of hair after one week, I would say this: hair grows on an average of 1/2" or 1 cm per month... so don't expect miracles after 1 week or one month.
