Thinning hair at 47YO

[JNAPS]

I'm 49 now, but started to notice my hair loss two years ago. I have a very small spot at the back of my head and I have noticed the hairline is receding a little. I went to a dermatologist a year ago and he gave me a prescription shampoo. It didn't really help at all. I was actually counting the hairs in the shower and in my brush and was losing about 75 to 100+ during my showers. Yeah, I know, I'm crazy!! =) My head was becoming itchy and I was getting zits or ingrown hairs on my head also. Also getting a lot of body acne and some on my forehead and face. It has slowed some now. I'm losing about half of what I was 2 years ago. But I do see what looks like my whole head thinning. Right now as I type this, my head is VERY itchy.. I don't really notice dandruff and flakes, but when I itch my head I get a lot of crap under my nails. I asked a few people that have lost hair and they said they didn't have what I have. No real itchy scalp of zits.. I went to the dermatologist again a few months ago and he looked at my head and did a pull test and said it's not bad, but he thought it was MPB.. I want to go to another doctor and a ISHRS Physician next. At 49YO I still like to do the wild thing with the wife, so I don't want to take a chance on the Fin.. The dermatologist I went to was using it and he said the side effects are true for him. So, the wife still looks hot for her age (49) and still likes to have fun so I gotta stay away from the Fin.. Anyone else on here with hair loss have the same things as me?
