So to make a long story short about 1 month ago when I got a huge cystic breakout (it's over now... ) I got two really big pimples on each side of my hair sides, near my forehead. Dumb as I was I put BP and salicylic acid on it and they were gone in like 3 days. Now today when I was inspecting my hair I'm seeing that the hair around that area (1-2 cm in diameter) is really, really thin... You can't really see it and if I let my hair grow out me myself can't even see it but since I'm rocking a 5-10mm undercut it's pretty easy to notice for me. Will this hair ever grow out or has the BP practically destroyed the hair there? Can I put some Rogaine on it and hope the best? It's not really a big deal but it looks like I've just woke up from bed in that area...

By the way I'm only 15...
