Sir i need help for my dandruff. I try to wash my hair only twice a week but even without a day unwashed my scalp starts flaking & also it gets itchy. Few months back i used Nizral 2% Ketoconazole shampoo and i was dandruff free for almost 4 months but after that scalp started getting itchy again and when i went to purchase NIZRAL again the pharmacy had NIZORAL and since both are for dandruff i got NIZORAL shampoo since NIZRAL wasn’t available at that particular store. I found it less effective than NIZRAL. Should i go back to NIZRAL 2% KETOCANAZOLE? Please suggest a good hair oil too. I have both dandruff & hairfall problems though i don’t have any health problems.
