Add-on services & treaments

How does K18 work with your hair?
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

K18 is perfect for any type of hair – coloured or not – that needs a hydration boost. We especially recommend K18 for coloured hair but there are plenty of other factors that can damage hair too, such as pollution, sun, and different styling products. Everyone can benefit from k18!

Yes – K18 is clinically proven to reverse damage at the molecular level, making it ideal for clients who regularly use heat tools. Whether it's daily blow dries or heat styling for events, this treatment helps restore smoothness, softness and shine from the inside out.
Unlike surface-level products, K18 uses a patented molecular breakthrough that works on a biomimetic level. Instead of just coating the hair, it reconnects broken keratin chains to truly repair damage. It's where biotech meets haircare – and the results speak for themselves.
To improve the effectiveness of K18, we often recommend using a detox shampoo first to remove product build-up. This creates a clean canvas for the leave-in molecular repair treatment, allowing it to penetrate deeply and deliver progressive results.
Absolutely. K18 is colour safe and actually helps protect hair during the colouring process. It restores hair strength and resilience, helping to maintain colour vibrancy and reduce frizz or dullness after your appointment.
K18 works on a progressive basis, meaning the results improve with continued use. While you’ll notice stronger, shinier hair after your first treatment, regular in-salon or at-home use builds long-term strength and smoothness.
