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.

Incredible products and great community

I’ve been trying to embrace my waves and tried many other products with little to no success. The 5 step Merwave process is easy to follow and works. I’ve posted questions on the FB group and received so much help/advice.

Amazing product

I had been looking at this product for a while before I bought it , as I must say I didn’t think it would actually work and is quite expensive , but I thought I’d give it a go and I have got to say it’s amazing , I had a bit of a wave and after using this product and let my hair dry naturally what a lovely curl that lasted for days ,might need to try refresh spray , I’ve had several comments on my hair to and have also been recommending product , well done merwave for creating such a great product,
