Usually I wear it straight...
First I apply CHI Silk Infusion, just a little bit to help protect it from the flatiron (plus it kind of adds a soften gloss to my hair).
Then, I use my CHI nano, and to add a little bit of volume I use a Matrix BIOLAGE bodifying cream gel underneath on my roots.
After that I spray a fine toothed comb with some volumizing herbal essence spray (cheap stuff, but it works and smells pretty) and go over my top strands lightly just to flatten out the frizz.
Ahhh that seems like a lot of steps, but it really only take about 4 to 5 minutes at the most. On other days I like to curl my hair, but that takes much longer.
