I've been able to grow a thick, full beard for as long as I can remember. My facial hair grows fast as well. However, in the last year, I've noticed the spot under my chin has slowed growth considerably. To the point where it looks like my beard is parted down the middle and I have weird jaw horns of beard. So I'm forced to trim the rest of my beard to keep it even with my under chin, and it saddens me.
tl;dr if anyone has any tips for growing hair faster in a single spot, send 'em my way, cause this old man misses his beard. Google basically told me that my options are either 1) do nothing, or 2) use rogain.
