It works inside the hair fibre to help reduce breakage, improve elasticity and leave hair feeling smoother and easier to manage.

More information

What the K18 Repair Treatment delivers

This treatment focuses on internal repair, so hair feels stronger as well as softer.

  • Hair and damage assessment, focusing on areas prone to snapping, roughness or excessive tangling
  • A cleansing prep to remove build-up and help the K18 treatment absorb evenly
  • Section-by-section application of the K18 leave-in repair treatment with timed processing
  • A finished style to check the result through the lengths and ends (smoothness, movement and reduced frizz)
  • Simple aftercare guidance on washing, heat styling and when to repeat K18 for best ongoing strength

Hair concerns K18 repair is designed to target

K18 Repair Treatment is particularly helpful if you notice:

  • Hair snapping when brushing, especially around the front hairline and through the ends
  • A stretchy, weakened feel when hair is wet after lightening services
  • Rough, porous mid-lengths and ends that will not hold shine
  • Persistent frizz and flyaways that return soon after blow drying
  • Highlighted, bleached or colour-treated hair that feels “tired” between appointments

How the K18 Repair Treatment is carried out

Your stylist will start by checking the condition of your hair and talking through recent colour history, heat use and any chemical services. Hair is cleansed and prepped, then the K18 repair treatment is applied carefully through the most stressed areas.

After processing time, hair is finished and styled so you can feel the difference in softness, strength and manageability straight away. K18 can be booked as a standalone repair appointment or added to a colour service when hair needs extra support.

After your K18 Repair Treatment: keeping hair stronger between visits

To make the results last, keep heat gentler and consistent, and avoid overloading hair with heavy products that can cause build-up. Your stylist can recommend how often to repeat K18 based on how frequently you colour or use hot tools, and whether you are growing out lightening.

If you are aiming for longer, healthier hair, regular repair treatments alongside trims can help reduce the cycle of splitting and breakage.

Frequently Asked Questions

Is K18 Repair Treatment suitable for coloured or bleached hair?
Yes. It is often chosen after highlights, bleaching and colouring when hair feels weaker or more porous. Your stylist will assess condition first and advise whether K18 should be done as a standalone service or alongside colour.
Will K18 Repair Treatment make my hair feel heavy or greasy?
It is designed to repair without coating the hair, so it should feel light and clean. If your hair is very fine or prone to build-up, your stylist will focus application through the most stressed lengths and ends.
How long will the results of a K18 Repair Treatment last?
You should notice improved softness and manageability straight away, with strength benefits building over repeat sessions. How long it lasts depends on how often you colour, heat style and how you care for hair at home.
Can I book K18 Repair Treatment with my colour appointment?
Yes, it can be added to colour services when hair needs extra reinforcement. It is particularly useful after lightening, or if hair has started to feel stretchy, dry or prone to snapping. Your stylist will confirm the best timing within your appointment.
Is K18 the same as a keratin treatment or a smoothing service?
No. K18 is a repair treatment that focuses on rebuilding strength within the hair, rather than coating it for straightness. It can help reduce frizz by improving hair condition, but it will not permanently straighten hair.
