I'm not sure if this would help you but I take methotrexate(which causes the thinning) and my doctors have me take folic acid to help it.

I was diagnosed with alopecia areata earlier this year & have grown back my patch almost fully with women's rogaine serum (1 bottle) & then women's rogaine foam (1 can) + Vegamour GRO serum, The Ordinary serum for hair density, The Nue Co. Supa_Thick serum, and a few other things on a routine schedule consistently! You can DM me if you'd like more info on the exact products 👍 also scalp massage & special shampoo/conditioner for hair growth + a hair brush that's designed for thin hair so it's not pulling as much out while detangling (the one I use is from Wet Brush). I understand hair loss can be disheartening, but you can grow it back🫶 I believe in you

My dr has me taking and can help with hair loss over time twice a day hydroxychloroquin
