How to use

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

1. Wash hair first

2. Apply plex treatment to wet hair

3. Leave on for at least 30 minutes (you can leave it on overnight). The longer it's left, the more time it has to repair your hair

4. Rinse off

5. Complete steps 1-5 of Merwave routine as normal

Restoring damaged hair takes time. There's no overnight miracle product. So you may need a few treatments before you see results.

Restore damaged hair from the inside out

How does your hair become damaged?

95% of our hair is made up of protein bond structures. These hold our hair shafts together, giving it its strength and stability. They keep the hair in the natural shape it was formed.

During heat styling, colouring and day to day life, these bond structures are broken down before being hardened into a new shape. This is referred to as ‘hair damage’.

This leads to spongy, weak hair strands and split ends that eventually break off. The hair is overly dry, rough and tangles easily. It loses its shine and looks dull.

The only effective long-term solution is to restore the internal structure of your hair.

How does this plex treatment work?

Using two small molecule ingredients (Hydroxypropylgluconamide and Hydroxypropylammonium Gluconate) Merwave’s Repair & Restore Plex Treatment restores and reconnects these damaged and broken bonds from the inside out.

Both molecules are designed to strengthen your hair from inside the fibre by penetrating deep into the cortex to create new hydrogen and ionic bonds.

This then supports the internal protein structure, providing up to 3X strength compared to untreated hair.

What results can I expect?

As the plex treatment re-builds your hair bonds, it strengthens the hair from within, making it more resistant to breakages and damage.

Damaged hair's more porous than healthy hair. Moisture cannot be retained, causing brittleness and frizz. This plex treatment will repair those damaged cuticles. Your hair will now retain the vital moisture required to stay soft and frizz free.

By restoring the bonds, your hair elasticity will be improved. Your hair will become more manageable and more resilient to styling. It'll be visibly shinier and healthier.

Merwave is the best!

I have been using merwave products since I started my wavy journey 15 months ago. I have tweaked it here and there and am now happy using steps 1, 2 and 3. I use a different mousse and gel which seem to suit my hair better. I also using the Merwave finishing oil, and the deep conditioner after using a clarifying shampoo. Very happy with my routine!! 😊
