I have been on Xeljanz for 2 1/2 months 5 mg 2X daily and just last week I got about 7 white, baby fine "vellus" hairs right on top of my head and many, many of the same hairs on my face !! Like forehead, cheeks, etc. I never had hair on my face before just above my upper lip that I would pluck. Thankfully, it is light. There are no other hairs anywhere else right now but I am hoping for more. I just wonder if "vellus" hair always means you will get "terminal" hair with pigmentation? ..
