Glow Guide
  • Broken bonds inside the hair get reconnected, not just coated over.
  • Softness and shine build with every repeat treatment.
  • Colour and heat damage stop compounding wash after wash.
  • Elasticity returns so hair stops snapping and breaking.
  • One bottle lasts through months of consistent repair.
Who's It For

Anyone who colours, bleaches or heat styles regularly and wants an ongoing leave in repair step built into their routine.

Description

K18 Leave-In Molecular Repair Hair Mask is a 4 minute leave in treatment infused with the patented K18 peptide, which works to repair even the most extreme damage and renew hair to its most youthful, healthy state.

Travelling deeper into the inner layers of hair than traditional repair products, the K18 peptide is just the right size and makeup to fit in and reconnect broken keratin chains, renewing hair with strength, softness, smoothness and bounce. You can feel and see the difference from the first use.

How to Use

Shampoo and rinse as normal, skipping conditioner, then towel dry thoroughly. Apply the mask and leave for 4 minutes without rinsing out, then style as usual. For best results, use for the first 4 to 6 washes, then every 3 to 4 washes to maintain strength.

How We Use It: We recommend this size for anyone making it a regular part of their routine, since one bottle covers months of repair, not just a single trial.

Ingredients

K18Peptide: the patented molecule at the heart of every K18 formula, travelling into hair's inner layers to reconnect broken keratin chains and rebuild strength, softness and elasticity from within.

Please Note: For an accurate listing of ingredients in each product, please refer to your product packaging prior to use. SkinShop also recommend all products are patch-tested 24 hours before application.

Hair feels good

Hair feels nice after use, only on 3rd wash and it says to use it for 6 consecutively so not sure how well it will work. My hair is quite fine and does get greasy a lot quicker with this product. Skin shop service was great

Not worth the money

I must be the only one that has found this product terrible. I have tried Olaplex but thought I'd try this since it's so much easier with one product & all the good reviews. My god what a waste of money I've used it five times so far & seen absolutely no difference. Never again.

Amazing

Omg this product is fantastic. I have dry, coloured - blonde hair. This has made my hair feel so soft.
I have shoulder length thick hair and find two pumps is enough.
