Hair Cycling, Shaft Thickness, and Propecia

Hi, I am 21 yrs. old and for the past several months my hair has been thinning diffusely throughout the top part of my head, with no change to my hair line. I have recently been prescribed Propecia by my physician and am hoping to gain an idea of the type of results I can expect. According to your blog, Propecia works best in the crown area of the scalp; so does this mean that my hair which has thinned in the front will not likely see any results?? Also, as a general question, you have stated that it may take upwards of 6 months to see new hairs, due to the slowness of the hair cycle. However, could it take less time for hairs to increase their shaft thickness while taking Propecia? I understand that the hair regrowth is dependant on hair cycling, but is this the same for also reversing the miniaturization process? Thank you for answering my questions!

The published information on hair regrowth from Propecia is best documented in the crown. I am convinced that there are good results in the frontal area behind the hairline in people your age (under 26) with recent hair loss or hair thinning. You must stay the course. Yes, it can work earlier, but it will slow down or stop the hair loss in many young men your age. Be patient.
