A single 5ml dose of K18's leave-in molecular repair treatment — the smallest way to try the formula the brand is known for. It is a four-minute, no-rinse step used after shampooing in place of conditioner, aimed at hair left porous and rough by bleaching, colouring or heat.

What's in it

  • K18PEPTIDE (sh-oligopeptide-78) — a patented bioactive peptide, formulated to act on the keratin chains inside the strand.
  • Hydrolysed wheat protein and wheat starch — conditioning proteins that smooth the surface of the hair.
  • Cetearyl alcohol and behentrimonium chloride — the conditioning base that carries it evenly through the hair.

How to use it

Shampoo and skip the conditioner, then towel-dry thoroughly. Both matter: conditioner film and excess water each get in the way. Work the dose through from the ends upwards, leave it four minutes, and do not rinse. Comb through and style as normal.

Worth knowing

This is a trial or top-up size, not a course of treatment. K18's own protocol runs four to six consecutive washes after a salon service, which needs one of the larger bottles. Use this to find out whether the formula suits your hair first.

Shampoo hair and do not condition. Towel-dry thoroughly.
Apply 1–3 pumps depending on hair length and density, starting at the ends and working upwards.
Leave on for 4 minutes. Do not rinse.
Comb through, then apply styling products as desired.

Use for 4–6 consecutive washes after a salon service, then as needed for maintenance.

Frequently Asked Questions

Q. How does K18 Leave-In Molecular Repair Mask repair damaged hair?

A. K18 is powered by a patented peptide (K18PEPTIDE™) that works at a molecular level to reconnect broken keratin chains inside the hair. This helps restore strength, elasticity and smoothness rather than simply coating the surface, delivering deeper and longer-lasting repair.

Q. Should I skip conditioner when using the K18 repair mask?

A. Yes. For best results, apply K18 on clean, towel-dried hair after shampooing and before any conditioner. Conditioner can leave a film on the hair that may inhibit the K18PEPTIDE™ from penetrating the hair shaft and working at a molecular level, so it’s recommended to use the mask first and then style or condition if desired afterwards.

Q. Do I need to rinse out K18 after applying it?

A. No. K18 is a leave-in treatment. After applying to towel-dried hair, allow it to sit for 4 minutes to activate. Do not rinse. You can then layer styling products on top and style as usual.
