K18 Pro - Leave-in Molecular Repair Hair Mask - 15ml

K18 Pro - Leave-in Molecular Repair Hair Mask - 15ml

The 15ml version of K18's leave-in molecular repair mask: the same patented K18PEPTIDE™, sized down for travel or for trying the 4-minute repair before committing to a full bottle.

Instead of coating the damage, the biomimetic peptide travels deep into the fibre and reconnects the broken polypeptide chains and disulfide bonds left by bleach, colour, chemical services and heat. Strength and elasticity come back from the inside, and the repair holds through your next washes.

• Reverses damage from bleach and colour, chemical services and heat.
• Visible results in 4 minutes; progressive results over the first 4–6 washes.
• Brings back strength, softness, smoothness and bounce instead of papering over the damage.
• pH 5.0–6.0 helps the cuticle close, sealing the peptide in so results last.
• Works on every hair type, because the repair happens at the molecular level.
• Vegan, colour-safe and cruelty-free.

How to use

• Wash with shampoo only: conditioning agents can block the peptide from reaching the fibre.
• Towel-dry until hair is thoroughly damp, not dripping.
• Start with 1 pump worked in from ends to roots, adding a pump at a time up to 3 pumps depending on length and thickness.
• Wait 4 minutes. Leave it in.
• Comb and style as usual (heat protectant and styling products are fine now).
• Use at every wash for the first 4–6, then as needed to maintain the repair.

Pro tip: buildup blocks the peptide's path. Washing with K18 PEPTIDE PREP™ Detox Shampoo first gives the mask a clean canvas to work on, especially in hard-water areas.
