A leave-in treatment mask for all hair types that repairs damaged hair in just four minutes. K18PEPTIDE™ restores hair damaged by bleaching, coloring, chemical treatments, and heat. It restores its strength, softness, and elasticity.

The leave-in mask is ideal for hair damaged by heat, lightening, coloring, or other chemical processes.

The mask contains the revolutionary patented K18Peptide™, which reaches the innermost layers of the hair, where polypeptide (keratin) chains are located in the core. It has the right size and structure to fit into them, reconnect disrupted chains, and repair broken disulfide bonds. At the same time, it restores the hair’s softness, elasticity, smoothness, and strength.

The mask is suitable for all hair types.

K18 products do not contain:
parabens, sulfates, silicones, phthalates, sodium chloride, artificial dyes, formaldehyde, or formaldehyde donors.

Before first use, wash your hair with K18 Detox Shampoo, a deep-cleansing shampoo that removes impurities, product buildup, and excess oil. This allows K18Peptide™ to penetrate the hair structure more effectively.

Wash your hair with shampoo, do not use conditioner, and then towel-dry it thoroughly. Start with one pump of the K18 mask, work it thoroughly between your palms, and apply it evenly from the ends to the roots. Depending on your hair’s length, thickness, and condition, add another pump as needed. The formula is highly concentrated, so use only 1–3 pumps and work in each dose of the mask separately.

The first time you use the mask, apply it as a treatment for 4–6 consecutive washes. After that, apply it as needed based on your hair’s current condition.

The K18 mask is neither a moisturizing nor a protein treatment, so if your hair is very dry, we recommend supplementing your routine with a suitable moisturizing or protein treatment as needed.

Follow the recommended dosage—do not use too much product.
