Customer Reviews
The products are great, really do what they say. I recently had a problem with the packaging and contacted customer service - they were prompt and very helpful, sorted it immediately. Excellent service!
Before menopause i had straight hair now im through the other side I've now got wavy / curly hair hadn't a clue how to look after it so tried a few other brands but didn't feel like I was getting the best out of my hair now after using Merwave I have lovey gorgeous curls and some wavy bits too ( think its called Irish hair??) Anyway Merwave is doing amazing things to my hair 🥰thankyou Merwave
Been strugging with my hair all of my life. This works!
My hair has always had a bit of a kink when air dried but post menopause the potential curl in my wet hair became fluff once dried. Usual
products for curly hair left my fine hair greasy and limp. With Merwaves I actually have wavy, in fact almost curly hair. It’s a game changer! My daughter is now also a convert, I would recommend to anyone
