Hello. Thank you for writing to us at healthcaremagic Dandruff or seborrheic dermatitis is quite common and is a common cause of scalp itching. Since dandruff is bound to recur, therefore rather than using a regular shampoo, you should use an antidandruff shampoo to keep dandruff under check. My choice for an antidandruff shampoo is 2% ketoconazole shampoo, thrice weekly OR even daily, for 2-4 weeks. Nizoral is a ketoconazole based shampoo and is available OTC. It is marketed by Johnson & Johnson. However sometimes a shampoo alone is insufficient in taking complete control of dandruff. In such a case dermatologists may choose to prescribe a topical steroid lotion (Mometasone lotion 0.1%), to be applied once daily at night, at the scalp skin for 2 weeks. Seborrheic dermatitis is a steroid responsive condition. Topical steroid lotion is a prescription product and a dermatologist would normally prescribe it for difficult to treat dandruff. The topical steroid lotion may be stopped once the dandruff is well controlled and thereafter the improvement can be sustained with just an anti-dandruff lotion/shampoo, twice weekly. You may try the shampoo first, it that seems insufficient you may visit a dermatologist in your region for the needful. Hope this information helps Regards
