I'm 18.
I had a slightly high hairline. That's natural for me.
I grew my hair long for a year. I also may not have had the best nutrition, and I had a lot of stress. Before it got real long I was channeling my stress into a disorder that involves pulling out hair. Ever since I was a little kid I used to twirl my finger in my hair and sometimes make knots, then undo the knots. I started doing this a lot.. thinned out a patch of my hair bad. Managed to quit through willpower. My hair got longer. It was also always frizzy and dry and kind of.. well, instead of being straight, being all frizzy looking, on top, this I attributed to abusing my hair before. When it was shoulder length, I started brushing regularly. I was getting a LOT of hair in my brush. In retrospect I don't see WHY I was so stupid as to not realize what was going on. I got my hair cut and the guy doing it told me my hair was really dry and said maybe I had a thyroid problem. My mom has one, so maybe I inherited one. Since I could tell my hair was looking a little thin once he had cut it down to normal length, I asked him to guess my age from my hair.
He said 'Oh, you haven't gone too far past 30 yet' or something to that effect. He barely believed me when I told him he was 18 until I pulled out some ID. His response was to tell me I was going bald.
I would note that over the year of growing my hair, I almost never washed it. Bleh. Big move, no shower at one end, no shower at the other. I kept it from getting stinky, no more. Never used any good shampoo or conditioner.
For a few months now I've been using 'damaged hair' shampoo and conditioner. I think my hair is improving a bit. I'm also taking a lot of silica supplement tablets with horsetail. But, my hair on top is still noticeably drier. I think the reason so much came out when it was long is the dry hair was easier to break when it was long. In the mirror, it looks thin on top in a pattern that looks like male pattern baldness. On the sides a little, too.
So. Any thoughts or ideas? As much as I like having everyone assume I'm much older than I am (mostly from my eyes and voice but now the hair too) I don't want to go through life losing my hair this early. Goddamit.
