I've been suffering from frontal thinning for around three years. I've used rogaine for around three years and this is the best that I've gotten. The front part of my hair refuses to grow so I leave it and shave everything else. I'm sick of looking in the mirror at it and it irks the hell out of me. Is smp an option? Would it allow me to grow my hair or would I have to keep it that same length that it already is?
