5 lightweight products formulated for wavy hair
Cleanse Shampoo
Contains Jojoba oil and avocado extract. Vitamin and mineral rich ingredients that deeply cleans, revitalises, soothes and nourishes your hair. Free of harmful ingredients (silicones, sulphates, parabens) which strip away your natural oils. This helps prevent frizz.
Repair Conditioner
Wavy hair craves moisture. Packed with hydrating ingredients such as Glycerin and Jojoba oil this conditioner will nourish and detangle your hair before holding onto the vital moisture needed to prevent your hair from frizzing and breaking. Leaves your hair oozing with moisture.
Feed Treatment
Hair is made up of 90% protein. Over time your protein structure will deteriorate causing weakness and breakages. No.3 is a leave in treatment that feeds your hair with the vital nutrients and proteins required to stay elastic, strong and healthy. Split ends and breakages will be a distant memory.
Cast Foam
A lightweight foam that locks our waves into a cast, without weighing them down. Contains Polyquaternium-16, which enhances the shape and definition of our waves by creating space between the hair strands. This provides volume by adding lift at the roots.
Protect Gel
Lightweight enough not to weigh your waves down, yet strong enough to maintain a soft, flexible hold without stiffness. The combination of polymers, conditioning agents and natural extracts enhance wave definition, control frizz and keep hair hydrated by locking in moisture. The result are juicy, frizz-free waves without the crunchy, stringy look.
Wavy hair isn't curly
Its finer. More prone to frizz. Which means you need lightweight, hydrating products to awaken your waves.

Hi everyone,
I never knew my hair was wavy.
For 30 years, I thought it was straight, unmanageable and frizzy.
I was chasing those flawless, sleek locks promoted in glossy magazines and movies. Convinced that anything less was unacceptable.
I fought with my hair. Becoming a slave to straighteners. Throwing it up in a bun whenever it misbehaved.
Then one day, a friend told me that those “weird” kinks, frizz and flicked-out ends were secret signs my hair is wavy.
So began my journey to embrace my natural waves.
But there was a problem…
Most products were made for curly hair. Loaded with heavy butters and oils. Great for curls. Too heavy for waves.
My hair became weighed down. Waves fell flat within hours.
Frustrated, I decided to create a range of lightweight, nourishing products specifically formulated for wavy hair.
Over 120,000 women have since used Merwave’s Wavy Hair Kit to transform their hair into soft, defined waves.
Our mission is simple: to help women break free from society’s idea of perfection and embrace their natural wavy hair.
That effortless, imperfect look. Hair that gives you confidence. Hair unique to you.
Whatever your age. Whatever the occasion.
The Merwave range will do that for you.
