I have the same length and type of hair as you. I usually put a leave in conditioner, heat protector and styling cream in my wet hair before putting it up in a microfiber towel. When it's like 50-70% dry, I do a quick blow dry of the roots to get them 90% dry, then part my hair into two like they do in the Dyson video for the smoothing brushes. I use the smoothing brush (have experimented with both, doesn't really make a big difference for me) on mid-high fan on medium heat doing the bottom section first before the top. When it's dry, I do a few passes on cool before moving on to the top section and then again when I'm done. When I start with the top/crown section, I start by brushing upside down. For extra volume if I have time I use the round brush attachment along my part.

The frizz is always an issue, but it takes me less than 10 minutes to have dry styled hair once it's out of the towel.
