I have something like dandruff on my head severely. It looks like skin flakes white and slightly yellowish. I tried many things like keto shampoo. Home remedies like curd. Lemon juice .bhringraj tail etc. But it comes back after 2 to 3 days. Its been many years I have this problem. Luckily I am not losing hairline nor losing hair. But my hair is not also dense my skin also flakes around nose and eyebrows sometimes .i regularly wash my hair 2-3 times a week with shampoo. I do not use any hair oil or product right now. But it is not leaving me. I don't know if is it really dandruff. Because keto shampoos did not work. I want to get rid of it. Whenever I touch my hair .the flakes fell off. On the scalp it is like scaled manner. I want to get rid of it and increase my hair density.
