Hi, Your problem which is scientifically known as “pityriasis capitis” is highest in twenties and then recedes by itself in later part of life. It is due to the fact that the renewal of skin and the fatty acid secretion in scalp is highest at this part of life. So there is a tendency to grow fungus as well which makes the flaking more perceptible. There are no such important predisposing factors except for few which can make the situation worsened. For the remedy part follow the things below: Wash your scalp daily. You will say you are already doing it. But my way of application is- it is to be done twice in a single bath. It means when you are washing your scalp apply first time shampoo for washing the hair part only, then rinse it off immediately with water. Reapply the shampoo again immediately, leave it for around 5 minutes, do a good gentle massage by your fingers for around 2 minutes and then wash it off. By doing so for around 7 days you will get good benefit. All the best.
