Restolin is a fairly well-studied supplement in accordance with its creator. William Anderson, the mind behind Restolin, told us that he had been actively looking for natural methods to support healthy hair growth for more than 30 years now. Being only 57 years of age, Anderson seems to have had hair loss problems since his 20’s. As such, most of the studies about Restolin came from the National Center for Biotechnology Information (NCBI), SAGE Publishing, medical articles, and many more. Therefore, Restolin is a well-researched supplement, and this is evident in how simple this product works in general. Therefore, we can all say it works like a charm and does not need any further explanation, for that matter.
