They ALL say they know. Everyone I know who's been to cosmetology school says they barely cover it. I always ask them if they have anyone who specializes in curly hair, and ask them what type of continued education they've done that focuses on curls.

Sometimes they get annoyed - tough poop. If they don't have a good answer, I say thank you, hang up, and call somewhere else.

Though I have run into some good curly stylists bc they have curly hair themselves, or their daughter does, etc. so it's not always specialized education, but I find that's the best marker.

Hopefully this next one goes better!!
