I always wear my hair straight as my naturally wavy hair looks frizzy but not with Merwave. Using the 5 step process left me with frizz free curls. Don't be scared to try Merwave. It takes a couple of trys to work out whats best for your hair, e.g diffuse or dry naturally. The refresh spray is great to use after sleeping, quick spray, crunch, diffuse and you are done. I'm embracing my natural curls & if I do go straight at any time I have used Steps 1-3 so if you don't embrace your curls you can still use the products.
