I have lupus and I noticed major changes with my hair prior to my diagnosis. My hair got very dry and snapped off, when I got relaxers a lot of hair would wash down the sink.
Once I was diagnosed, I was placed on steroids, placquenil, mobic, and actonel. I also developed sores in my scalp that never healed from relaxers. But the steroids helped my hair grow long and strong. I grew hair everywhere. Thats when I discovered waxing
My Rheumatologist added chemo,(methrotrexate) while I was taking the steroids, and I was still okay. But as soon as I was winged off the steroids my hair thinned out every where, to where you can see my scalp very clear. That particular med had major side effects, and hair lost was one of them.
A white doctor told me to stop putting chemicals in my hair because my body is taking in meds and it is releasing chemicals in my hair. This made sense because my hair started to look like I was overprocessing it. ( I go to the salon and they put a mild relaxer on every 2 months)
If you think about it some jobs don't want a urine sample, they want to clip your hair strands to test for drugs. So our meds are in our hair.
Needless to say I have been natural for over 3 years now and get my hair press every 3 wks. My hair grew down my back. My edges are a little thin, but I am happy now.
This doesn't affect all Lupus patients, I have friends that dye their hair regualarly and relax with no problems.
