I was, and still am, losing my hair. It started about 10 years ago and I didn't know what to do. My hair dresser said if my parents had thinning hair, welcome to the club. Well, my dad lost his hair when stationed in New Guinea during WWII. They would have to get their head shaved every so often because of lice over there. My mom lost a lot of her hair when she worked at a shoe factory. The cause was supposedly leather dust. What's my excuse? I have none. I'm so bummed because my hair was my greatest asset. Same with mom.
Anyway, I developed a lump on the side of my neck so I went to the ENT I worked for and it was a cyst but it was't the cause. Then when I had radiation treatments, I really lost a lot of hair. (I call it male pattern baldness.) My doc sent me to another ENT because the first one died of brain tumor, and i was diagnosed with hypothyroidism, Hashimoto's disease, and something else. Hair loss is a symptom of hypothyroidism. He couldn't decide the true problem. He put me on Levothyroxine and I thought things would get better. It didn't. I started taking Hair, Skin and Nail vitamins because of problems with all 3 but they didn't help either. So I'm resigned to it now. Got my hair cut real short (not my idea) but it just made it worse. I have 2 wigs, one with too much hair and the other too small so I can't wear any. Had a 3rd one but it was too big! I'm in-between a petite and an average size. Mom had a couple nice wigs but when she died, I gave them to the American Cancer Society. Kick myself now.
Oh, I know. Yakking too much. Anyway, get your thyroid checked, too. That might be the problem. Today, my hair faills out a little slower but it still falls out. My next stop is the local "hair consultant" to see if there's anything I can do.
