If you're taking any medications, check the side effects. My hair has started to thin on top (I'm 52) and I found out that it's a side effect of the cholesterol-lowering drug that I'm taking.
Mu husband uses Nioxin shampoo for his thinning hair and has noticed a difference. I might give it a try!
Read up about thyroid help & the symptoms of low thyroid. The adrenals have something to do with it. Also sea salt (celticseasalt.com) has sodium, which the adrenals need to make those hormones & many trace elements. It is not the same as table salt & works naturally. If you've been on a sodium reduced or free diet, this can be the problem. Kelp capsules will help, also get some iodine, too. I take iodoral. It's also on the net.
I've had this problem since I was 37, 20 years ago, so I've researched this subject in so many ways.
