Dear Dr. Rassman,
I have been diagnosed with seborrheic dermatitis on my eyebrow areas. My eyebrow hair are falling off all the time. They do grow back, but I notice that the texture of the hair is thinner than before I have got the problem. Does seborrheic dermatitis affect hair follicles in such a way as to cause the hair strands to get thinner?
Thank you very much for your time.
Anything is possible. If you scratch it, you may be pulling out hairs and eventually this will lead to permanent hair loss. You can treat it topically with a low dose steroid (1/2% hydrocortisone cream) about three applications a week, 12 hours apart. This can be purchased over the counter and is safe, unless you take too much of it. Try it for the short term. If it works, see a good dermatologist to consult on what is the best way to keep it under control.
