FOURTH STEP IN THE BIOPLEX ROUTINE. The Protective Hair Mask is the definitive solution to protect and revitalize hair after an intensive treatment. This mask is formulated to seal and protect disulfide bridges, providing an additional layer of protection that helps prevent future damage. In addition, its repairing action acts deeply, revitalizing the hair from the inside, providing stronger, more flexible and visibly healthier hair. PROTECTION AND SHINE. It not only protects, but also improves the texture and shine of hair, leaving it looking healthy and radiant. It is ideal for all hair types that need an extra dose of care and protection, especially after intensive treatments. BIOTECHNOLOGICAL FORMULA. It takes advantage of advanced biotechnology with low molecular weight yeast peptides to penetrate the hair fiber, where it acts by reinforcing damaged areas and protecting the hair structure. The result is hair that not only feels softer and more manageable, but is also more resistant to damage caused by external factors such as sun, heat or chemical treatments. USE ON ALL TYPES OF HAIR.
