I’ve shaved my head for the past 5 years since I was 29 because I was thinning on top…I starting using Procerin in conjuction with the Rogaine foam for 2months before I let it start growing in…It’s awesome. The areas that almost had no hair is now sprouting little baby hairs, and the rest is growing in thicker than before. So far so good. Its been four months and everyone at work keeps asking me why I shaved my head.
