Product Details

Apply to soaking wet hair. This will evenly distribute the product.

Flip your head upside down. Take the Merwave Cast Foam and rake it through gently. Then take small sections of your hair and scrunch them up towards your scalp. Squeeze slightly to get rid of excess moisture to help the drying process.

You then scrunch in a small quantity of Protect Gel to hold that definition in place. This lightweight gel won’t weigh your waves down unlike heavier gels. Simply diffuse or air dry as normal.

Great Products

I’m fairly new to Merwave products. I love them. I’m still playing around with my “product recipe” and enjoying the results. Delivery time was good too.

Amazing wavy hair products

I've been using Merwave for a few years now and my waves continue to improve. The products are brilliant quality and reasonably priced. There is a great community of Merwavers who all offer tips and support to everyone on their wavy journey. I really rate the way the company constantly listens to their customers and continues to innovate and bring out new products. Their latest wave cream is now a firm part of my routine and I can go longer and longer between washes since this. Highly recommend.

Super products for wavy/ curly hair.

So glad I found Merwave. After years of straightening my hair, I have finally decided to embrace my natural wave/ curl. Merwave products have enhanced this transition and their advice is second to none. Very helpful customer service. Highly recommend these products and please support a small British company.
