I don't know whether I have a dry scalp or dandruff problem. Everytime I use some shampoo like Head & Shoulders, my hair and scalp remains normal and problem goes away for 2-3 days but then it resurfaces. Then have to use the shampoo again and this cycle repeats itself. I have used coconut oil, almond oil and Navratan but nothing works. Also my scalp is not that oily when I don't use any oil but it isn't too dry as well and hence I am confused. Please suggest me something because this has been happening to me since a long time and it is very irritating.
