Hello. Thank you for writing to us at healthcaremagic I will keep a possibility of seborrheic dermatitis. Itching and scab/ scaling being suggestive of seborrheic dermatitis. If I was the treating doctor I would suggest you to use a ketoconazole based antidandruff shampoo, every alternate days. Ketoconazole is antiseborrheic and antifungal and brings about rapid relief in mild to moderate seborrheic dermatitis. In some cases, a shampoo alone seems insufficient and providing complete relief, therefore, in such cases, I usually ask my patients to use a topical potent steroid, twice daily at the scalp skin. Seborrheic dermatitis is a steroid responsive dermatoses and topical steroids bring about rapid improvement in this condition. Once remarkable improvement has been achieved with topical steroids, usually within 2 -4 weeks, they can be discontinued. Seborrheic dermatitis is a recurrent skin condition, therefore regular use of an antidandruff shampoo is important to prevent a recurrence. Regards
