Meet The K18 Hair Essentials Your Routine Needs
Powered by the patented K18PEPTIDE™ complex, each and every K18 product helps to repair bonds broken by excess heat styling, bleaching or environmental stresses. What’s K18PEPTIDE™ made up of? It’s a string of amino acids that mimic the structure of keratin, which is the protein that makes up your hair. By replicating keratin, K18PEPTIDE™ helps to repair and strengthen your hair.
What we love most about this haircare range is how straightforward it is. K18 is a brand that likes to keep it simple with fewer than 10 products. We’ve outlined a few of our favourites, including the new launch, Heatbounce, which we’re predicting will be huge!

K18 HAIR
PEPTIDE PREP™ detox shampoo, £39.00
The Nourishing Detox Shampoo
Detox shampoos have a place in almost every hair routine, but few of us use them because they have a reputation for rinsing away all the moisture with excess oil and product build-up. K18’s detox shampoo contains the all-important K18PEPTIDE™ to help keep your hair and scalp nourished. It’s also perfectly pH balanced to avoid drying out your scalp. Use it once a month, fortnightly or every week, depending on your hair type and product usage.
K18 HAIR
AirWash™ Dry Shampoo, £48.00
The Weightless Dry Shampoo
Unlike most of the dry shampoos on the market, K18’s is a non-aerosol spray formulated without starch. This lightweight spray uses translucent mineral microbeads to soak up excess oil and leaves your hair feeling and smelling fresh.
K18 HAIR
Molecular Repair Hair Oil, £27.00
The Game-Changing Hair Oil
If you’re looking to nourish dry, frazzled ends or smooth frizz, K18’s hair oil is a must-have. The lightweight formula helps to condition hair without leaving it feeling greasy or weighed down. We recommend warming a couple of drops up in the palms of your hands and combing through your hair.
K18 HAIR
HeatBounce Conditioning Heat Protectant, £48.00
The Shine-Boosting Heat Protective Spray
We saved the best until last. If you’re someone who can’t live without their curling tongs, this heat protection spray is essential. Providing a shield to heat up to 232C while also helping to condition hair and boost shine, this multitasking spray is an all-round hero.
