How dry should hair be before blowing it out?

My natural hair type is wavy/curly. It’s fine, type 2B/2C. Straight hair helps me feel a bit more confident and is lower maintenance so I choose to blow it out once a week.

I use the Dyson airwrap large round brush and the smoothing brush to straighten my hair. I use both on high heat and high speed.

I just never know how dry my hair should be. Normally, I use it on hair that’s almost dry, so around 70-80% dry, since I’m afraid of heat damage. But, my blowout always turns out frizzy and it feels like I have to pull my hair harder.

A few days ago, I had to do my hair in a rush, so I did my blowout on mainly wet hair. I’d say it was around 50% dry, or maybe a little less. The blowout turned out so much better, required less tension, and went by quicker. I’m just afraid that doing it on wet hair increases heat damage.
