Medrol will help with the daily pain. It's a non-steriod anti-inflamatory.
Methatrexate will help calm the disease.
My hair only thins during bad flares. I take biotin to help strengthen it and wash my hair in Organix Biotin and Colligen shampoo.
When my hair thins it always comes back curly. I've hadn't had curls since I was a baby.
