Topical applied vitamin B6 ointment improved adult seborrheic dermatitis in one study. However, oral vitamin B6 was ineffective. One physician reported that injections of B-complex vitamins were useful in the treatment of seborrheic dermatitis in infants.242 A preliminary trial found that 10 mg per day of folic acid was helpful in 17 of 20 cases of adult seborrheic dermatitis.243 However, this study also found that oral folic acid did not benefit infants with cradle cap. A preliminary study found that topical application of vitamin B6 ointment (containing 10 mg B6 per gram of ointment) to affected areas improved adult seborrheic dermatitis.244 However, oral vitamin B6 (up to 300 mg per day) was ineffective. Injections of vitamin B12 were reported to improve in 86% of adults with seborrheic dermatitis in a preliminary trial.245 Oral administration of vitamin B12 for seborrheic dermatitis has not been studied.
