After years of battling frizz and flat waves, I stumbled across the Merwave Wavy Hair Kit, which claims to define wavy hair without weighing it down. With promises of soft beachy waves, no nasties, and a simple routine, I decided to take the plunge and try it for a full wash day cycle.

What Is the Merwave Wavy Hair Kit?
The Merwave Wavy Hair Kit is a curated set of five lightweight, Curly Girl-approved products designed specifically for wavy hair. It includes: cleanse Shampoo & Repair Conditioner (jojoba oil, glycerin), feed Treatment (leave-in protein and moisture booster), cast Foam (polymer-enhanced, lightweight mousse), and protect Gel (flexible, non-crunchy hold)
The brand emphasizes breathable texture, frizz control, and long-lasting wave definition without heavy waxes or silicones.
Why I Tried It
I’ve tried curly-hair products before and ended up with limp, weighed-down strands. Merwave stood out because it’s formulated for fine, wavy hair that needs volume and moisture, not heavy curl creams. With so many positive reviews online, I figured it was worth a proper test.
My Experience Using It
I followed their 4-step routine… shampoo, conditioner, feed treatment, foam, and gel, on soaking-wet hair. The foam is impressively light and easy to scrunch up waves without making my hair crunchy. After air-drying, my waves felt soft and bouncy, and looked defined without stiffness.
By day two, I spritzed a little water and scrunched with their refresh spray, and my waves revived nicely without frizz. That’s a win, I’ve had routines where waves lose shape within hours.
Still, not everything was perfect. After sleeping on it once, knots formed at the back, and it was tough to detangle without ruining the wave pattern. Also, a Trustpilot reviewer mentioned breakage after months of use, especially along the hairline, so long-term protein impact might be a concern.
Overall, my hair felt healthier and looked more defined than usual, but it took a bit of trial and error to dial in the right amounts and styling order.
Pros
- Lightweight texture that doesn’t flatten fine waves
- Helps define wavy patterns without stiffness
- Reasonably short routine… about 15 minutes once you know the steps
- Positive feedback from users with thin, frizz-prone waves
Cons
- Can cause knotting overnight, especially without protective sleep styles
- May cause breakage or dryness with frequent use, especially around sensitive edges
- Pricey for a full kit (~£70–85 GBP / $85 USD)
- Some Reddit users found individual gels or mousses disappointing compared to lighter mousses from other brands
Is It a Scam?
No, it’s definitely real, and the community around it is vibrant and active. But not everyone loves it. Some reviewers call the ads misleading and say the products under-deliver for coarse or thick waves. The breakage feedback is enough to warrant caution, but there are genuinely happy users, too. It’s reliable, but not glamorous.
Where to Buy & Price Point
Available via Merwave’s official site or UK retailers, the kit typically sells for ~£70–85 GBP (about $85 USD) and includes a free deep mask. Over 120,000 kits sold, with about 4,700 five-star reviews.
Alternatives
- Only Curls Starter Kits
- Curlsmith Gel and Mousse
- Boucleme styling bundle
Conclusion: Would I Recommend It?
If you’ve fine or wavy hair and have felt frustrated with heavy curl products, the Merwave Wavy Hair Kit is worth testing. The shine, bounce, and control can be real, just use gentle habits like silk pillowcases or pineapple protection when sleeping.
But if your hair is coarse or prone to breakage, tread carefully or start with a single product. It’s not miracle-making, but with regular use and the right technique, it can elevate your waves in a fresh, low-fuss way.
