The CRLab SEBUM REGULATOR SHOCK ACTION kit (also for oily dandruff) acts by purifying the scalp from an excessive presence of sebum which can also damage the metabolism of the hair bulbs. In the kit there is 1 complete set of pre-shampoo, shampoo and vials for more than a month of treatment (5 weeks). The line ensures a scalp without excess sebum for a long time, and strong and healthy hair. Excess sebum, which can have hormonal or stress or wrong diet causes, has a very negative impact on the quality of our hair which appears heavy, thin and brittle. To reinvigorate the hair we act at the scalp level thanks to specific active ingredients with an astringent and antioxidant function.
