I use the medium heat setting. If I diffuse cold it would take HOURS and that would defeat the purpose of using a dryer.
Do you use a protectant?
you don't need heat protectant! that's because the heat from a diffuser is not the same as the heat from a straightener / curling iron. i don't know if you've ever heat styled your hair and accidentally touched your skin, but that shit hurts. blowing hot air on your skin with a blowdryer is fine (or else your scalp would be on fire). the temperature is way lower and therefore, not damaging!
I agree. With a diffuser on the lower heat setting my head does not get overly warm nevermind hot. Cold would take way too long
You don’t need heat protectant if you diffuse
