K18 Pro - Leave-in Molecular Repair Hair Mask - 50ml

Most repair products sit on top of the damage. This one goes in after it. The patented K18PEPTIDE™ is a biomimetic molecule, small enough to travel deep into the hair fibre, where it reconnects the broken polypeptide chains and disulfide bonds that bleach, colour, chemical services and heat leave behind. Four minutes later hair is visibly stronger, softer, smoother and bouncier, and because the repair happens at a molecular level it holds through your next washes instead of rinsing back out.

It works the same way on every hair type, and it keeps improving over the first 4 to 6 uses.

• 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.
