Hi guys, so I'm 21 years old and have been experiencing hair loss for about a year and a half. I would probabaly say I have lost 50% of my hair on the top with minimal loss on the sides. I went to a dermo when I was 19 and he said it was probably due to my medication I am on for Crohn's disease due to it only being on the right side of my hairline. Right now I'm getting huge amount of hair loss on my head along with bad recession on the right side of my hairline but only small recession on my left side. My dermatologist took a scalp biopsy which diagnosed me with diffuse alopecia areata. I'm unconvinced, is this just male pattern baldness I am suffering? Could it be both AA and male pattern baldness? The only reason being that the hair loss has been insanely fast. I have used rogaine on hairline with no success but have used a topical steroid application prescribed by my dermo for the last week. I'm just looking for some advice, should I just try and give propecia a go? I'm just worried in case it has a bad effect along with my current medications for Crohn's disease. Thanks in advance.
