Frontal hairs that don’t grow

Question for you. I am 41 years old. Been on Finasteride for four months. From the tip of my hairline to about 3 inches back has miniaturized slightly. I have noticed that it no longer grows in length. Is this common? I have to buzz cut the rest of my head to match that front part every few weeks. What could be the reason for this? Why don’t those follicles grow anymore…it is like they have paused the growth cycle at the front?!

Great question. When hairs are going to die, sometimes they just stop growing or the growing slows down almost to a crawl.  These hairs will eventually fall out and contribute to patterned balding. Drugs like minoxidil (topically) or finasteride can reverse this process.
