K18 Salon Treatment

Undo hair damage with unique peptide technology

Repair damaged hair and make your hair feel like new

What is K18 hair?

K18 is a haircare product we use in the salon with patented ingredients clinically proven to reverse hair damage caused by chemical services, over-styling, heat and environmental damage.

Someone described it to us like this: “K18 can be seen as the upgraded version of Olaplex. It’s like having a new iPhone compared to an old phone”.

It repairs your hair by reconnecting the damaged keratin chains that are the building blocks of hair, restoring its strength, softness, smoothness and bounce. Essentially, it makes damaged hair feel like new.

How does it work?

The inner structure of hair is made up of polypeptide chains (also known as keratin chains). When these structures get damaged, keratin chains break.

Unlike traditional hair treatments and conditioners that coat the hair, K18 works to penetrate the hair’s inner layer and reconnect broken chains, reversing the signs of damage.

K18 is perfect for strengthening hair before chemical treatment or helping to repair damaged hair. Damaged hair is dry, brittle, dull and can lose its shine and elasticity.

It is an ideal hair treatment for:

  • Bleached or coloured hair
  • Heat styling and heat-damaged hair
  • Hair that has undergone any kind of chemical service such as permanent waves
  • Hair suffering as a result of environmental stressors such as dry winter air, strong sun or pollution

Why you'll love it

K18 repairs hair by restoring its core structure to renew strength and elasticity.

  • Strengthens hair
  • Restores smoothness and softness
  • Restores bounce and flexibility
  • Promotes manageable hair with fewer tangles
  • Suitable for all hair types

K18 can also be used as an at-home treatment to restore hair, reverse damage and leave you with that salon-fresh feeling at home!
