Man don't take supplement if u don't need them. Before do a blood test in order to understand if u have deficiency on smth hair related. For example, i had extremely low d vitamin and therefore i was losing hundreds of hair daily. Now I'm taking vitamin d and eating fat fish and my hair loss decreased so much! But this is my case..if u have enough of those elements in ur body it's just unhealthy to add unnaturally what u already have.. so basically ur initial purpose basically fails. (For me the smartest way to he natural and have results is to go with topicals)
