I'm 21, and I used to have extremely long and thick eyelashes. About 2 yrs. ago, I started having back problems, which became degenerative disk disorder, spinal stenosis, sciatica, etc. I now have extensive nerve damage. The point is that ever since this began, my eyelashes have been falling out. I'll admit I'v never been very nice to my lashes, with lots of mascara and probably not proper removal of it, but I've still never had a problem until this happened. Now, I wear mascara maybe 3 times a week and use the best makeup remover I can. Yet, they continuously get thinner and thinner, with gaps now in between. Another problem that started following the back problems, surgery, and added meds (Lyrica, Vicodin, Celebrex, Flexeril) is that my scalp and eyebrows have also gotten worse. I now have very severe dandruff, with scabs on my scalp, and my hair has begun to thin--my eyebrows are nearly as bad as my lashes. I don't know if any of this is related, but it has made me very self-conscious about it and everything I do does not help.
