K18

K18 hair treatment for damaged hair

K18 is a bond-repair haircare brand built around its patented K18PEPTIDE™. It's made for hair that's been through bleach, colour, chemical services or regular heat styling. The K18 Leave-In Molecular Repair Mask is the hero: a 4-minute, no-rinse treatment, with 5ml and 50ml sizes at glamaCo alongside the K18 Molecular Repair Mask 150ml.

To use the K18 mask, shampoo and skip the conditioner, then towel-dry until damp. Work 1 to 3 pumps through from the ends up, leave it for 4 minutes without rinsing, then comb and style as usual. K18 recommends using it for 4 to 6 washes after a colour, chemical or heat-damage event, then as needed. Browse more repair options in our hair masks, leave-in conditioners and treatments and hair and scalp treatments.

K18 oil and mist for shine and frizz control

K18 Molecular Repair Oil 30ml is a lightweight, weightless hair oil that strengthens and repairs damaged hair, reduces frizz and adds shine, with heat protection. Apply 1 to 2 drops to damp or dry hair, focusing on the mid-lengths and ends, then style as usual. The K18 Molecular Repair Mist 300ml is also in the range. For more finishing options, see our hair oils and hair serums.

K18 shampoos, dry shampoo and volume

K18 advises clarifying first so the peptide can reach the hair. The K18 Detox Shampoo (250ml and 930ml) is the clarifying step, and the K18 pH Damage Shield Shampoo 250ml and K18 pH Shampoo 930ml round out the wash range. Explore all our shampoos.

For between washes, K18 AirWash Dry Shampoo 118ml refreshes hair, and K18 AtroLift Volume Spray 118ml adds lift at the roots. See more dry shampoos.
