The heat setting for curly hair types really comes down to whether the strands of hair are thick or fine.
"Surprisingly, a lot of curly hair can actually be really fine," Polko says. "If that's the case, then you'll want to use a low heat setting. If the hair is very fine, you could also blow it out beforehand with a paddle brush to cut down on heat styling."
If you have curly hair that's a little thicker, you'll want to use a higher heat setting. Most straighteners go up to 450 degrees, but since curly hair is more susceptible to being damaged by heat — heat styling it too much can ruin your natural curl pattern — it's not entirely necessary to use a setting that high. If ever you're attempting to straighten or blow out your curly hair, try to use a very minimal temperature that doesn't go above 350 degrees.
