Dandruff is made up of clusters of dead skin cells that cover the scalp.
On dry scalps, dandruff is made up of dry, small, fine white flakes that easily shed and are thus visible on dark clothing. On oilier scalps, the flakes are larger and thicker and tend to stick to the scalp at the base of the hair.
Many people consult their doctors for this frequent disorder, which is associated with scalp irritation and itchiness.
Ιt is essential to choose an effective anti-dandruff shampoo, which has good cosmetic qualities so that it doesn’t dry out the hair and is both gentle and effective. It must be specially formulated to prevent an increase in seborrhea, due to the elimination of sebum (reactive seborrhea).
An anti-dandruff shampoo must be left on the hair for at least 5 minutes for the active ingredients to optimally work. In all cases, a hair care maintenance treatment is necessary to prevent dandruff from coming back.
