Personally, when I want it, I like it a lot. I only straighten for trims, cuts, occasional boredom, or to see progress. And honestly, learning all about my hair in its natural state taught me how to do my hair in any state if that makes sense. Even flat ironed, my hair is rarely bone straight. I love volume!
But usually it only stays that way for a week max. Then it's back to my curls!
