Since I quit smoking I noticed that my hairline changed and my forehead became smaller. Also the 'M' shaped hair of me with the 2 bald spots got smaller, but I also recently started sunbathing so i'm not sure if it's because of the sun or quitting smoking. In a certain light I can see tiny white and black hairs filling up my scalp and at the 2 bald 'M' spots I can see hairs coming again. Also if I pull back my hair I can see more and more hair popping out at the front of my scalp since I quit.
