My temples receded from my highest wrinkle brow to 1.75 inches. You said a mature hairline temples are up to 1.5 inches away from that wrinkle. So I’m slightly more which is fine by me. But around those corners there is a piece of short hairs, they seem to have the same thickness as a lot of my front hairs but they look like they will fall of since I assume they are miniaturized. After that my temples will be about 2-2.2 inches receded which will be too much. I just began Propecia and am almost 22 years old, can Propecia stop those hairs from falling out and even help them grow normal again? But I’m also taking Propecia because I have frontal and mid anterior probs as well but early stage.
Propecia will slow or stop the hair loss in most men of your age. Consider sending me photos (will be kept private) and I will give you an opinion, but you should consider getting your hair mapped out for miniaturization to determine if these hairs at that exact location are really miniaturizing.
