Pictures would be helpful here, seeing that seborrheic dermatitis rarely causes hair loss itself. There may be another reason you are losing hair. Despite that, I have my patients use Latisse (off-label) or Revitalash on their eyebrows to help with growth. It works great. If there is no benefit, I have them get hair transplant, unless the cause is autoimmune like alopecia areata and then injectable steroids may benefit. I wish you the best of luck, Dr. Emer.
