I need to let my hair dry for about 15-20 minutes before using this. Even with towel dried hair my hair has too much moisture, but I had to do the same thing with the regular dryer too.
I have below the shoulder length hair- I find that by pinning my hair into sections (top/bottom layer) then drying works well. Very similar to what I did with a hair straightener- Make sure you use a heat protectant! I use pure energy leave in conditioner and Olaplex6 for smoothing (Used both of these when I used a brush and regular dryer)- I could see someone very easily damaging their hair if they overused the dryer or if they didn’t use it protectant
I still have to use my hairdryer for the roots at the top of my head. The brush on this is quite large and yes, it does lift under the root, but I don’t like to leave it there as it gets too hot. I finished drawing the sides in the back.
The whole process takes me About 10 to 15 minutes- With regular brush/ dryer, it took me about 25 to 35 minutes to dry my hair- ( if I wanted a decent style and finished look)
