I have patchy beards, I started derma rolling once a week since February and let just say beard got thicker but not growing much, patchy beard as before. Found out topical minoxidil has shown promising results but yes it's a long game, I understand that. I found 2 such topical solutions namely, Mintop 5% and Man Matters 5% Beardmax (almost half the of mintop). For whoever is reading this, I have 2 questions to ask--

1. Does minoxidil work on beards? If yes what's the routine one should follow?

2. Which topical solution should I buy? Mintop, man matters or something else?
