K18 Hair Treatment

K18 hair treatment is a quick leave-in salon mask that repairs hair from the inside, undoing damage from bleach, colour and heat rather than just smoothing it over. It suits hair that tangles into knots after lightening, feels rough even after conditioner, or has lost its bounce from years of straightening.

What is a K18 Hair Treatment

K18 hair treatment is a professional salon procedure for deep restoration that works from within, reconnecting damaged keratin chains in your hair. Unlike surface conditioners, this product penetrates the hair cortex, rebuilding its structure at the molecular level. It is one of the bond-repair hair treatments available at PIED-DE-POULE.

This treatment is perfect for hair damaged by coloring, bleaching, chemical treatments, or heat styling. If your hair has become brittle, dry, or lost its elasticity, hair treatment K18 is designed specifically for you.

How It Works

This procedure uses patented K18Peptide™ technology, which precisely replicates the amino acid sequence in hair keratin. This formula penetrates to the hair’s core and reconnects broken chains, restoring its natural structure in just 4 minutes.

K18 works as a “reset” for your hair, returning it to its pre-damage condition. This isn’t temporary problem masking, but genuine restoration at the molecular level.

Where Olaplex focuses on rebuilding disulfide bonds, K18 works on the keratin chains themselves, which is why it acts in a single short step.

What to Combine K18 With

A K18 salon treatment fits easily into a longer visit, because the mask takes just 4 minutes and stays in the hair. Clients often book it:

straight after bleaching or hair colouring, to start repairing the hair the same day;
before a haircut, so the stylist works with stronger, smoother ends;
with a blow-dry, as the leave-in formula doesn’t get in the way of styling.

How the Procedure Is Performed

Consultation

Your specialist checks the level of damage and how your hair has been coloured or styled. Together you confirm that K18 is the right fit.

Deep Cleansing

Hair is thoroughly washed with a specialized shampoo that opens the cuticle for deep penetration of active ingredients.

Precise Application

The K18 mask is applied to towel-dried hair, distributed evenly throughout the length. The stylist concentrates on the most damaged mid-lengths and ends.

4-Minute Activation

The formula stays on hair for just 4 minutes, during which peptides penetrate the structure and reconnect broken bonds.

Leave-In Finish and Styling

The treatment is completed without rinsing, allowing active components to continue working even after you leave the salon. Hair is then dried and styled as usual.

Home Care Advice

The specialist explains how to maintain the result at home. You also get a recommendation for when to book your next session.

Benefits of K18 Hair Treatment

RESTORED STRENGTH
The peptide reconnects broken keratin chains, so strength and resilience return straight after the treatment.
HEALTHIER MOVEMENT
A repaired internal structure brings back elasticity, so hair stretches and springs back instead of snapping.
NATURAL SHINE
A rebuilt hair core reflects light more evenly, so natural shine returns without silicone coating.
RESULTS ON SEVERE DAMAGE
The formula works deep in the cortex, so even heavily bleached or over-processed hair responds.
CUMULATIVE EFFECT
Each session builds on the last, so hair gets stronger with every treatment.
NO WEIGHT, ANY TEXTURE
The leave-in formula is lightweight, so it suits all hair types from straight to curly without weighing them down.
