Yes, it is especially recommended for dyed, bleached or highlighted hair. Hydrolysed collagen and keratin work directly on the hair fiber damaged by chemical processes, restoring elasticity and strength without affecting the colour.

For very damaged hair, 2 times a week during the first 3-4 weeks. Once the hair recovers, 1 time a week is enough to maintain the result. For healthy hair seeking maintenance, 1 weekly application.

Conventional masks work on the hair surface with silicones that provide temporary softness. The Karseell Mask works with hydrolysed collagen and keratin that penetrate the hair structure and repair real damage. No aggressive silicones, no sulfates — ingredients that genuinely work.

From the first application you will notice softer, more manageable hair with less frizz. Deep repair of the hair fiber consolidates with continued use — after 3-4 weeks the change is clearly visible in shine, elasticity and resistance to breakage.

Yes, it works with any shampoo. To maximise the result, use the shampoo first, rinse well, and then apply the mask from mid-lengths to tips. If your shampoo contains aggressive sulfates, consider combining it with Karseell's Maca Care System Shampoo to enhance the repairing effect.
