Use this shampoo mainly on the scalp, because dandruff forms at scalp level rather than on the hair lengths. Wet the hair and scalp well, apply a suitable amount of shampoo, then massage with the fingertips across the areas where flakes or oiliness are most noticeable. Avoid scratching with nails, as this can make an already uncomfortable scalp feel more irritated.
Because the formula contains cleansing surfactants and salicylic acid, give the product enough contact with the scalp during washing to help loosen sebum, impurities and dead skin cells. You do not need aggressive rubbing; a careful massage is usually more effective and gentler. Rinse thoroughly so that loosened flakes and cleanser residue are removed from the scalp and roots.
If your hair lengths or ends are dry, you can follow with conditioner on the mid-lengths and ends only, keeping heavy conditioners away from the scalp if oiliness and flakes are a concern. This helps maintain hair softness without counteracting the scalp-cleansing purpose of the shampoo.
How often to use it depends on your scalp and washing habits. Many people start by using an anti-dandruff shampoo regularly while flakes are visible, then adjust based on comfort and results. If you notice stinging, unusual redness or increased irritation, reduce frequency or stop using it. Avoid contact with the eyes; if it gets into the eyes, rinse well with water.
