RADICAL Anti-Dandruff Shampoo is intended first of all for the scalp, where flakes, oil build-up and itching usually start. Wet the hair thoroughly, apply the shampoo to the roots, then massage the foam over the scalp with your fingertips. Focus on areas where flakes or oiliness are most visible, such as the hairline, crown or behind the ears, rather than scrubbing the hair lengths.
Let the lather work on the scalp briefly while you massage, then rinse well. The lengths do not usually need the same amount of direct shampoo: as the foam rinses down, it will cleanse them without unnecessary rubbing. This is helpful because anti-dandruff shampoos can feel more cleansing than everyday formulas, and over-washing the lengths may leave some hair types feeling dry.
The recommended routine from the product information is two or three times per week. If you wash your hair more often, you can alternate with a milder shampoo on the other wash days. For coloured, bleached or chemically treated hair, apply a nourishing conditioner mainly to the mid-lengths and ends after rinsing, while keeping heavier conditioners away from the scalp if your roots get oily quickly.
Avoid contact with the eyes and rinse immediately with water if it happens. Keep the bottle out of reach of children.
