Regaine is worth a try. It didn't work for me but may for you. I have alopecia - no hair at all now. There are a few threads on here re hair loss which may help you.
I haven't any advice in products, I'd just like to say I hope you find something to help. I have lost my hair has twice in recent years with it returning when my health improved, so I know how it can get you down. I live in fear of it happening again.
My hair loss improved when I stopped using dye and anything with chemicals on my hair. I use organic shampoo/conditioner and Argan oil, seems to have stopped hair fall out and encouraged growth. If you’re used to colouring you might have to go cold turkey.
Have any of you used Regaine foam for woman to help with thinning hair? I can now see my scalp through my hair on top of my head and my hair is noticeably thinner, just hoping there is something I can do to stop it getting any worse. Any advice would be welcome.
