Apply the RADICAL trichological scalp exfoliator before your usual shampoo, directly to the scalp. It is intended for the skin at the roots, not for cleansing the hair lengths. Part the hair in a few places, distribute a small amount over the scalp, then massage with your fingertips using light circular movements.
The product works in two ways: fine granules help lift away dead skin cells, dried sebum and residue from styling products such as dry shampoo, while cosmetic active ingredients help soften the upper layer of the skin so the cleansing feels thorough without needing harsh pressure. Do not scratch with your nails, as this can irritate the scalp and make flaking or sensitivity worse.
After massaging, rinse well and follow with shampoo. This order matters: the scrub loosens build-up first, and shampoo then removes the loosened residue from the scalp and hair roots. If you use scalp serums, ampoules or masks as part of a hair-strengthening routine, apply them after washing, when the scalp is clean and free from product build-up.
Use it once or twice a week rather than daily. If your scalp feels sensitive, tight or unusually dry after use, reduce the frequency or pause until the skin feels comfortable again.
