It's really not that bad at all as far as hairloss goes and compared to others on this site: but here's the mistake I made when I first noticed the same kind of slight thinning on top. First I asked everyone's opinion and they all told me I was crazy and paranoid about it and that there was nothing wrong with it. Obviously I could feel it getting thinner and they couldn't so they were not in the best position to give advice. You know your own hair better than anyone else, if you've felt a change enough to get on this site, make an account and post pics then that already is a good indicator that something's up with your crown. So at first I thought to myself: ''Even if I am thinning, it's not so bad, I mean people can barely notice any difference and I definitely do not look like a balding man so why worry?''. A year went by and it only got worse yet I naively thought :''Okay maybe it looks like I am a balding man but hell I still have a decent hairline, it could be worse AND I'm definitely not going to risk my sex life with propecia for such minor hair loss ''. So to recap I kept thinking I could deal with it as it progressively got worse and worse and now, three years later, it's as bad as it ever was and you would have to be blind to not notice I'm balding. Finally I realized that I couldn't even style it anymore and that it was no longer an unacceptable look but the joke's on me : if only I would have acted sooner and ignore everyone's advice I could have completely reversed it by nipping in the bud as early as possible and never worry about it again but fk no...people kept telling me it wasn't that bad until eventually it unavoidably got that bad. So my advice is do something now, and save you're hair for the next 10 years and never have to spend countless hours of your life worrying about it.
