Having super flat, non volymous hair, I have since somewhere in the middle of highschool almost constantly been curling my hair to get some texture into it. So much, that most people think I have curly hair while it's actually super flat. But of course, even after finding out about the wonders of heat protection, all that heatstyling damaged my hair baaadly.
So I found this about two years back, and I wanted to share it with you: sponge curlers.
I've bought mine for like 2
$ on ebay. I roll my hair up when it's slightly damp and wear them to bed, and I wake up to bouncy curls. Today I rolled them pretty hard, all the way down to my roots, which gave me this super fluffy curly mess á la the 80's, but you can allso roll them halfway to your roots, looser, or put more hair onto each roll for way softer, more controlled curls.
These have saved my hair from at least some of the heat styling I've put it trough so far, so if you want fluffy curls that stays all day without damaging your hair much at all: try them out, it's worth it. ♥
