Although there have been many claims about the effectiveness of these types of products, there appears to be very little clinical data to back them up.
For my own education I tried two of these products mainly because they are the only methods I have found, that claim to permanently stop white hairs from growing on the face. As these are the only types of hair that I am currently concerned with having used other methods on the rest of them. My own results have been very disappointing, having seen no difference, between the state of hair growth now, compared to before I started treatment. I therefore recommend that you look elsewhere and save your money.
