Streax Professional Vitariche Care Smooth and Shine Masque is a deep-hydrating hair mask that nourishes and revitalizes dry and frizzy hair. It contains Biovit-A-OX complex, a blend of biotin, vitamin B5, vitamin E, and hydrolyzed silk protein, that helps improve hair elasticity, smoothness, and shine. This masque also detangles hair and reduces split ends, leaving your hair soft, manageable, and glossy. Use it once or twice a week after shampooing for best results.
