What's the difference between the NB1 shampoo and mask?

The shampoo gently cleanses without sulphates while preserving keratin, while the mask offers intense repair thanks to its higher concentration of nourishing active ingredients. Both products are formulated to work in synergy to optimise results.

How do I use the NB1 shampoo and mask duo correctly?

Start by applying the shampoo to wet hair, massage gently and then rinse. Squeeze out the water from the hair and then apply the mask from the lengths to the ends. Leave on for 5-10 minutes (up to 20 minutes for very damaged hair). Rinse thoroughly with lukewarm water.

How often should I use the duo?

For hair that has had Brazilian straightening, use the duo every time you wash (2-3 times a week maximum). For other hair types, the shampoo can be used with every wash and the mask 1-2 times a week.

Why are these products sulphate-free?

The absence of sulphates is essential as these agents can remove natural keratin and the keratin deposited during Brazilian straightening. Our gentle formula cleanses effectively while preserving the hair fibre and prolonging the effects of treatments.

Are the products suitable for all hair types?

Yes, the duo is suitable for all hair types, especially hair that has been treated, coloured or had Indian, tannin or Brazilian straightening. The balanced formula is suitable for both fine and thick hair.

What are the main active ingredients in the shampoo and mask duo?

Both products contain pure keratin to repair, precious oils (prickly pear, black cumin, olive) to nourish, and pomegranate extract to protect. This synergy of active ingredients ensures complete action: repair, nutrition and protection.

This duo is perfect for hair that is damaged, dry or weakened by chemical or heat treatments. It is also ideal for maintenance after Brazilian or tannin straightening.

Yes! It is formulated without sulphates, parabens or silicones, guaranteeing softness and safety for your hair and scalp.

Is it suitable for colour-treated hair?

Yes, this duo protects colour while providing moisture and shine.
