The K18 Leave-in Restorative Hair Mask is suitable for all hair types. Thanks to the unique K18 peptide, hair is intensely repaired, and its elasticity is strengthened and improved in just 4 minutes! This intensive leave-in treatment also softens and detangles the hair.

Permanently repairs damage - reconnects both polypeptide chains (and thus the disulfide bonds) for strength across the length and width of the hair - provides comprehensive, lasting damage repair.

Repairs hair from even the most extreme damage - by working on the inner layer of the hair, strength and elasticity are renewed for strong, smooth, and resilient hair.

Delivers immediate and long-lasting results - the hair is repaired from the first use and continues to benefit from the next wash, providing lasting restorative benefits.

Simplified recovery - the convenient leave-in formula works in just 4 minutes, without the need for additional rinsing.

Works on all hair types - as K18PEPTIDE™ operates at a molecular level (where all hair is the same), this product is effective on all hair types.

Important! Before using the K18 mask, your hair should be clean. If you use a lot of styling products and/or heavy products with oils or silicones, this may leave a residue on your hair, preventing the optimal absorption of the K18 mask. Therefore, it is recommended to use a detox shampoo and wash your hair possibly twice.

In the shower:

• Wash your hair with shampoo and avoid using conditioner.

Out of the shower:

• Pat your hair dry with a towel until it's damp.
• Start with 1 pump of the K18 mask and use more if needed. The amount depends on the length, thickness, and condition of your hair.
• Spread the mask evenly through your hair from the roots to the tips, one pump at a time. Remember, less is more!
• Let the mask sit for 4 minutes to allow the peptide to work its magic.
• Do NOT rinse out the K18 Mask.
• Style your hair as usual.
