BENEFITS
BENEFITS
- Normal shampoos aren’t strong enough to fully break down product residue, excess oil and impurities. This clarifying formula resets hair and scalp when waves feel heavy or greasy.
- Unclogs hair follicles, allowing the scalp to breathe, which promotes healthier, more robust waves
- Lifts away weight and residue so your natural wave pattern looks more defined and lasts longer between washes.
- Formulated with powerhouse ingredients like cocamidopropyl betaine (a gentle cleanser derived from coconut oil creating a rich lather while gently cleansing without over-stripping), salicylic acid (an exfoliant that effectively removes scalp buildup, excess oil, and dead skin cells) and lauryl glucoside (a mild plant-derived surfactant that gently cleanses without stripping hair)
- Comes with a super fresh grapefruit scent
- Forever lightweight - all of Merwave’s products are specially formulated to ensure your waves won’t be weighed down
- Silicone, sulphate and paraban free.
- Safe for coloured or bleached hair

How to use the Clarifying Shampoo
“This is my go-to when my hair feels heavy, full of buildup, or when I need a proper deep clean to let my waves breathe again. I love using it as a full reset and always follow with a deep conditioning treatment so my waves drink up all that moisture and come back fresh, light and revived.”

I have chin-length fine grey hair(72yrs). It’s been crinkly when wet for years since menopause. My hairdresser has tried diffusing and other products when I wanted a change from heat straightened, but it always turned into a woolly mess when dry or later the same day.
Merwave really really works. I’m thrilled with my natural waves and with not having to wash and straighten every other day. I now can leave 5-7 days between washes. And it’s often gets better on the refresh days.
If you’re debating this (like I did for over a week!) stop now, and give it a go. I wish I’d found this technique decades ago!
Bought steps 1-3 lovectge shampoo and conditioner and learning less is more with the cream at step 3
Recently gotten clarifying shampoo OMG so good leaves hair feeling so clean
Love my waves more
Vegan friendly too hence my purchase just wish they did refills to use less packaging
fab product, but second day I look like I have been in a storm!
I am 65 years old with salt and pepper wavy hair. I’ve struggled with frizz all my life, and living by the coast doesn’t help. But no more! The Merwave system is a godsend! I now only need to wash my hair once a week, with just a little of the wave cream as a boost if “the gorilla” has visited in the night or the Cornish “moist” weather has descended. Brilliant stuff! And the travel set is ideal for trips in the campervan or to visit the kids
I’ve always blow dried and straightened my fine hair but was becoming increasingly frustrated at the frizz, kinks and limpness anytime there was moisture in the air. I’ve been using Merwave for 6 weeks now and am loving my waves, of which I have more than I thought!! Great products and I’m enjoying experimenting with the different steps!
I have been using the range of products for a few months and am very happy with the condition of my waves! Frizz free
