Has anyone used them, or can recommend?
I have longish (bra strap length) hair. It's not thick as such but there's a lot of it. It has a definite wave snd I've recently discovered that if I let ot dry naturally and dont brush it, it's very definitely bordering on curly. I'm keen to try and embrace the wave but not sure if this sort of product is worth the investment especially given how expensive they are.
