Seborrheic dermatitis patients are suitable for a hair transplant. If the patient has scalp ringworm, then they should wait for at least 5 years after the start of their treatment. A patient with scalp ringworm should not have hair transplant 6 months after the diagnosis. Hair can grow back in people with scalp ringworm. If the hair does not grow back after 5 years, and the treatment is not working, the patient can consider having a hair transplant.
