But is it really that bad every time? I know a few girls who always curl damp hair and their hair seems fine. Yeah heat on wet hair isn't great, but a one time thing causing four inches of damage sounds extreme. Maybe it was already damaged or she cranked the heat way too high. Sometimes these warnings make it sound like you'll ruin your hair forever from one mistake, but in reality it's more about how often you do it.

My grandpa had this beat up mug with a faded fishing logo. The design wore off but that thing kept coffee hot for hours. New mugs are all looks, no staying power.
