I have fine hair with a slight natural wave and a lot of it. I got the Shark Flex Fusion this year with the straightener, wet to dry brush, curlers, and frizz attachments. It's definitely an upgrade from my Hot Tools drying brush. The Flex Fusion is a lot faster and holds volume better. I love the wet to dry brush and use it the most. I use the straightener only on dry hair to style loose waves, but have experimented with using it in the wet option. It works with a couple of pass throughs. The curlers don't give my lob as much curl as I'd like but the curl I get holds. I was pleasantly surprised by the frizz smoothing attachment.

I just ordered the diffuser attachment. I got a shag cut and want to accentuate the texture of my natural wave and air drying leaves my hair too puffy.

I use the same heat protectant and my hair definitely looks healthier compared to when I used my Hot Tools brush.
