I think I've finally figured out how to incorporate diffusing to really increase the wave in my hair.
I co-washed with Tresemme Naturals Volume (Which, I actually like by the way, I think because it's less moisturizing I can go longer without a low-poo) and when I applied my hair products I flipped my hair completely to the right, then all the way to the left, then upside down. I plopped, and mostly diffused my hair upside-down.
Or, gathered the hair in the strainer as I was upside down, held it to my head, and held my head upright as I blow dried through the strainer. If that makes any sense.
And BAM! Good hair day.
And even though I haven't been getting the best 2nd day hair by putting my hair in a satin sleep cap at night, I'm still going to use it until my satin pillowcases I ordered get here. Just for the sake of keeping my hair healthier. It could be making a difference.
