Where science meets hair care, K18 believe that to truly care for our tresses, we must understand the biology behind it. Swapping out the lab coat and test tubes for a salon chair and hair tools, this brand is here to help you transform your locks from the comfort of your bathroom! Healthy hair all lies in the prep, so it’s time to welcome the Peptide Prep Detox Shampoo to your hair care regime — a weekly power cleanse to remove build-up and pave the way for your styling products to work even more effectively.
Next in line to K18’s groundbreaking product line-up is the Peptide Prep Detox Shampoo — formulated to nourish hair while removing build-up and grime to create a healthy hair canvas. Think: more vibrant colour, optimised performance of your styling products and nourished strands…
It all started with the Leave-In Molecular Repair Hair Mask — a unique leave-in formula that has shaken up the hair care industry and left the tresses of countless beauty mavens stronger, softer, smoother and bouncier than ever. Now it’s time to meet the Peptide Prep Detox Shampoo and extend your K18 collection for even better results. Engineered for less frequent, heavy duty washing, this colour-safe shampoo is microdosed with the patented ‘K18Peptide’ to reduce protein loss and leave your hair softer and healthier. A blend of salicylic acid and activated charcoal unite in this non-stripping lather to unclog hair follicles and banish oils, metals and dirt, leaving you with a clear path for your K18 Leave-In Molecular Repair Hair Mask to get to work. It’s not just your styling products that will benefit from this cleanser though — chemical treatments will perform better and hair colour will apply more vibrantly thanks to this clarifying shampoo. Inhale this clean citrus scent and get ready to welcome in a new era of even healthier swish-worthy tresses…

Bought for son
He uses a lot of gel ets and has dandruff which he keeps under wraps with a well known anti dandruff shampoo that’s very strong . Been trying to wean him off that. Have done that with this product . It works

Hair Detox
I use this two to three times a month just to get any extra build up of product that might be in my hair. It works really well without stripping my hair of any moisture

Nice
The shampoo is nice. It cleans out my scalp but im still seeing some hairfall. I guess its because of my scalp health. Its not too stripping though. I use it once a week.

Leaves my scalp feeling so clean

Absolutely essential
I wash my hair once or twice a week, so this is essential for ensuring my hair is clean and detoxed of any products. I find it really works well for my naturally wavy, thick hair and helps keep frizz to a minimum too.
