I have tried several oils that didn't work, but Dr. Brooke's started to work after a short period of using it. Before I started to use Dr. Brooke's on my beard, I had a couple of spots that wouldn't really grow. After a few weeks, I started to see the difference, and now, after 3 months, the spots are filled in. The scent and how it hydrates my beard is AMAZING!
