Benefits of the Strategic Combination

Post Discoloration Repair
Collagen Mask replenishes weakened hair fiber, restoring elasticity and preventing breakage.

Accuracy Nuance
The Purple Mask uses high intensity violet pigments to neutralize yellow and copper highlights instantly.

Professional Format of 500ml
Two large bottles that ensure complete maintenance of your hair for months.

Hydration and Extreme Shine
While the collagen strengthens, the actives in both masks seal the cuticle for a mirror-like shine and silky softness.

Frequently Asked Questions
Can I mix both masks in one application?
Although you can do this, we recommend using them separately in different washes. This way you allow each formula to fulfill its specific function: one focused on protein nutrition and the other on color correction.
What type of hair is this pack for?
It is essential for bleached blondes, platinum, balayage or gray hair suffering from dryness and color loss.
How do I know if the masks are legitimate?
On our official website we guarantee the traceability of each product. The original Purple Mask has a deep violet color and the Collagen Mask has an unmistakable dense and creamy texture.
