it definitely can grow hairs on your temple. Scalp is scalp, afterall.
I think receding temples are a very difficult area to grow hair back though. People on this forum have discussed this ad nauseum.
While I have gotten surefire growth in my temples I can't seem to get the hair in that area to GROW out full length. It grows out to like... a 3 clipper guard length then falls out. It's like being attacked and destroyed even with the help of the increased blood flow minoxidil provides.
I'm on like 4 months so, I'll try minoxidil for a year and see what happens. Maybe they are cycling in thicker and longer each time.
