According to the product description, it's a straightening iron, so it does exactly the opposite: straightens frizzy, curly and wavy hair.
The only "wavy" thing I can achieve with it is to turn the iron 180° when pulling the last 10cm of hair through - this gives the ends of the hair a certain "bounce".
Otherwise, for me (natural curls) it's the best hair straightener I've ever had.
If I want a nice wavy hairstyle, I use my Auto Curler from Philips.
I don't know exactly whether it works, but if you fill the container with descaler and then let it run into the void until the descaling liquid has been used up?
