Hello, I am 24 years old, I had a slight baldness top left and right, I lost a lot of hair. Then my hairdresser advised me this coupled with shampoo, after 6 months hair hush had worn off, and after a year the beginning of baldness begins to decline and reverse. I use it once a day in the morning after I wrung hair. So here it is not a magical product that arranges everything in 2 weeks, it does not exist if it was not, but at least here there is an effect that is certe in the long run, I put 3 stars because I think it is expensive anyway with the shampoo.
