I lost a lot of of my hair through chemo. My eyebrows too. I always had my hair cropped and spikey. Even though I have periods of losing it now when I am in a lupus flare that lasts for a while, I find it rather disconcerting even though I am sure it will come back in fullness before long.
As you know our hair often thins and can become somewhat patchy when lupus is active. Not all people go through this but those of us who do usually get the growth back when our flare is under control.
This doesn't happen unfortunately with people with discoid lupus, as the scars that are left by the rash leave permanenet bald areas.
Also some of the medications can make the baldness happen. Cytoxic drugs can cause it. The hair should regrow when the drug is discontinued.
Take care everyone.
