It is easy-to-process and cost-effective while offering flexibility across end-products categories (shampoo, rinse-off conditioner, and leaveons).

When introduced into the lightening powder or post-added to the colour cream just before the application, it enables to significantly reduce the damage to the cuticles. It also provides visible anti-fading benefits.
