Shu Uemura Hair Mask has been specially designed to strengthen hair, delivering enhanced nourishment to the areas with the most damage. This effective formula aims to restore the health of the hair shaft, reducing breakage and leaving it healthier and stronger. Applying the mask is simple: after washing with lukewarm water, you can spread an amount equal to two walnuts on damp hair. It is recommended to concentrate from mid-length to ends, performing a light massage to ensure deep penetration of the product. Leave the mask on for at least 5 minutes, and for better results you can wrap your hair in a warm towel. Rinse with cold water to close the hair cuticles.Quantity: 75mlAction: Reinforcement
