I'm going to be honest with you: I hate doing my hair. I love the way my hair looks when it's done nicely, but I don't like investing any effort into it. That's why most days my straight-to-wavy hair ends up in a ponytail or messy bun. Every so often I'll curl or straighten my hair, but that's pretty rare (especially now that I'm home all the time). Outside of my normal ponytail or bun, the only hairstyle I do regularly is two French braids — and the subsequent messy waves after I take the braids out. I always want my hair to look nicer, but I just don't do it.
The hack involves wrapping your hair around a bathrobe belt, sleeping on it, and waking up with gorgeous curls. I was skeptical — I've tried some similar hacks in the past (one with a headband, one with long socks, and one with curling rods), and they've never really worked for me. Sometimes they ended up way too curly, and sometimes, by the time I woke up, all my hair was flat again (I roll around a lot in my sleep).
The only bathrobe I have has a really thin, fabric belt, so I folded it in half to try to make it thicker. I wrapped my hair around the belt, adding more hair as I went, and tied off the bottoms with hair ties.
When I unwrapped a few pieces of hair, I knew it was going to be good. My hair was so curly! I kept carefully unwrapping my hair, being careful not to brush through any curls too early. Once the whole bathrobe belt was out, I ran my fingers through the curls to separate them.
I was obsessed. I added a little bit of hair oil to help with the frizz, then I shook out my hair. I honestly couldn't believe the curls worked. Not only did they work, but they were flattering and so fun!
