How does hair become damaged?
How does hair become damaged?
95% of hair is made up of protein bond structures that provide strength, stability and shape. Hair damage occurs when these are broken down, leaving strands spongy, weak and split – eventually breaking off. Moisture is hard to retain, and brittleness and frizz are common.
How does the plex treatment work?
How does the plex treatment work?
The formula is powered by two small-molecule ingredients (hydroxypropylgluconamide and hydroxypropylammonium gluconate) that penetrate deep into the cortex to create new hydrogen and ionic bonds – restoring and reconnecting fibres for up to 3 x stronger hair compared to untreated strands.
What results can I expect?
What results can I expect?
As the plex treatment rebuilds bonds, it strengthens the hair, making it more resistant to breakage and damage.Elasticity will improve, and strands are able to retain moisture and be more resilient to styling. Expect soft, shiny, frizz-free waves! Remember: Restoring damaged hair takes time and patience – you may need a few treatments before you see results.

How to use

Shampoo hair first, then apply enough plex treatment to fully saturate wet hair

Comb through the product to detangle and distribute

Leave on hair for at least 30 minutes – the longer it's left in the hair, the more time it has to repair (you can even leave it on overnight!)

Rinse off and style as usual

Abi's tip!

"Use whenever your hair feels dull and damaged, or after you've been on holiday and subjected it to sun, sea and chlorine."

WHY ABI MADE THIS

"Through years of colouring, heat and everyday life, my waves were damaged and crying out for some extra love. I created this because I needed a formula that could actually repair the damage from the inside out. I love how this plex treatment rebuilds the broken bonds, brings back strength and smoothness, and makes my hair feel like itself again – soft, healthy and full of life."
