The hardness of the Dandruff can be minimized by the following measures-

* Lifelong cleanliness and hygiene holds the key to controlling this condition
* Use an oil-balanced formula for an oily skin
* Diet: Eat a well balanced and healthy diet.
* Sunlight maybe good for dandruff as during summer season people suffer less from the condition.
* Avoid chemical treatments, using soaps or detergents in the affected area. They may cause drying and induce the condition to flare up.
* Avoid exposure to extreme weather.
* Shampoo: Keeping the scalp clean is important and for this using a shampoo regularly can help. Shampoos containing selenium sulfide, ketoconazole, tar, zinc or pyrithione are available without doctor's prescription.
