K18 Deep Clean Shampoo

K18 Peptide prep detox shampoo 250ml is perfect for prepping the hair for maximum repair results with K18 Molecular repair treatment.

Clean hair is a perfect base for a colour service to achieve great vibrancy for treatments to work more effectively and for styling products to work better. Please note that if you are having a scalp bleach service do not wash your hair for at least 48 hours before the service.

Having the correct pH level, as in K18 detox shampoo results in minimal cuticle swelling or lifting to protect your colour and maintain natural moisture levels.

Some products such as those for volumising or curl enhancing can build up in your hair and a good clarifying shampoo is the best way to remove them.

Unlike some other brands K18 uses only 17 ingredients (with no unnecessary fillers) plus K18’s peptide, these ingredients are skin-care inspired, so you can feel good about what’s in it and what’s not!

What is K18peptide?

Your hair can suffer from damage from bleach, hair colour, chemical services, heat styling and sun damage. This damage can go below the top layer of your hair and into the lower levels, the deepest of these are made up of polypeptide chains.

K18 Scientists spent a decade researching the keratin chains in the inner hair shaft and found one unique sequence that was just the right size and molecular structure to reconnect broken polypeptide chains. This patented K18peptide brings hair back a like-new, youthful state.

K18 reconnects broken polypeptide chains, it restores the hairs core structure, renewing hairs strength and elasticity. This treatment goes deep into the hairs structure repairing your hair at a molecular level so it is long lasting, as it remains in the hair even after being exposed to water and shampoo.

K18 will help your hair colour last longer and over a period of use and strengthening of your hair, this will allow your hair colourist and hair stylist to really create some fantastic and lasting results!

Key ingredients:

Activated charcoal, salicylic acid and a patented oligopeptide called K18peptide. This replaces lost amino acids to repair the hairs keratin structure.

    I have tried lots of clarifying shampoos and they can often make your hair feel dry after but this has left my hair feeling lovely and smooth. I really recommend it
