Dandruff that keeps coming back and also falls on the chest and shoulders is usually a long-term scalp condition, often linked with excess oil and a mild fungal overgrowth on the skin. This is why K Shine shampoo helps while you are using it, but the flakes return when you stop completely. You don?t always need to use it daily, but stopping suddenly is usually the reason for relapse. Most people do better with a regular schedule for some time, like using it 2-3 times a week when the dandruff is active, then slowly reducing it to once a week or even once in 10-15 days as a maintenance routine. Also, try not to keep oil on the scalp for long hours, and wash off sweat after heat or exercise. Changing clothes often can help reduce flakes on the body. If itching is strong, redness is increasing, or the problem keeps repeating even with regular shampoo use, it?s better to get checked once so the treatment can be adjusted properly.
