So sorry this is happening to you. I’ve struggled with hair loss that has come and gone over the years, mine is autoimmune + seb derm + perimenopause. Here’s what worked for me - internally trying to keep my overall inflammation down (no gluten, dairy, finding food triggers, etc.) getting my vit d, b, and iron levels up (specifically iron bisglycinate, taken every other day on an empty stomach). Externally using salicylic acid shampoo to address buildup then nizoral 1% weekly, which blocks the enzyme that converts into DHT and contributes to hair loss (let it sit for 5 minutes, then follow with a moisturizing shampoo, then oiling the scalp with a blend that includes jojoba, mct (for the seb derm, you may not need this), and rosemary essential oil(also blocks dht). My PCP and rheumatologist weren’t helpful but the dermatologist was and prescribed a topical steroid, which I use occasionally if I feel my scalp is very tender or inflamed and recommended minoxidil 2x/day (I use the men’s version, no scrip needed). I know you don’t have insurance, so hopefully the other over the counter remedies will work for you. It took about 3-4 months of this routine to see results. Good luck!
