Ducray Sabal Sebum Reducing Treatment Shampoo 200 ml is specially designed to clean oily hair. It delays re-greasing and keeps hair healthy and light. Sebum is produced in small quantities to coat and protect the scalp from external aggressions. This production can be stimulated in excess by hormonal imbalance, stress, pollution, etc. The hair becomes greasy, shiny and heavy. Ducray Sabal contains concentrated extract of Sabal Serrulata, an anti-seborrheic active ingredient that acts directly on the mechanisms responsible for sebum secretion. This action is reinforced by the specific pH, perfectly adapted to oily scalps. These combined actions normalize the production of sebum and delay re-greasing, thus making it possible to space out the frequency of shampoos. In addition, suitable volumizing agents make your hair light. This fresh, light feeling is enhanced by its delicately minty fragrance. Dermatologically tested.
