Treatment & Masks

Hair treatments are the difference between hair that survives and hair that thrives. Intensive hair mask treatments, deep bond repair, protein masks, hydrating treatments, leave-ins, scalp tonics, and overnight serums for every hair need, all with salon-level performance.

Whether your hair needs deep conditioning, colour protection, moisture restoration, or scalp nourishment, a quality mask transforms your home care routine. Our Wellington stylists recommend weekly masks for colour-treated, damaged, or dry hair, and use intensive treatments in-salon during specialist services.

K18 Leave-In Mask: 4-minute molecular repair

The K18 Leave-In Mask is the flagship of the K18 range. Unlike most masks that coat the hair surface, the patented K18PEPTIDE penetrates the cortex and repairs the broken polypeptide chains responsible for damage from bleach, colour, heat and chemical services. It is a 4-minute leave-in (no rinsing) used after every 4 to 6 washes. For best results, clarify first with K18 Peptide Prep Detox Shampoo, apply on damp hair, then finish with K18 Repair Oil. Browse the full K18 collection.

Build your routine: Pair with our Shampoo and Conditioner for complete weekly treatment, or explore Scalp Care treatments and Hair Oils for targeted support. Compare intensive care: Try K18 for biotech molecular repair, Davines for natural-inspired restoration, Olaplex for bond-building repair, or Oribe for luxury treatment. Let our team recommend the perfect mask for your hair.

FAQ

How often should I treat my hair?
Once or twice a week is the sweet spot for most hair types. Heavily damaged hair may benefit from more frequent treatments to begin.

Do I rinse out hair treatments?
Most masks rinse out. Some treatments, like K18 leave-in or Epres mist, stay in the hair.

What is the best treatment for damage?
Bond builders like K18, Olaplex No.3, and Epres are the most effective for true molecular repair.

Can I use treatments on fine hair?
Yes. Choose lighter formulas and apply mid-length to ends rather than the scalp.

What is the difference between a treatment and a conditioner?
Treatments are more concentrated and active than everyday conditioners, with targeted ingredients for specific concerns.
