Review (5/5): ... have beach waves without using heat and fell in love with the concept
I preferred these after seeing a youtube vid on how to make your hair have beach waves without using heat and fell in love with the concept!
These work great! I lost one while traveling, so will be buying another set, but even in a tropical, humid climate, the waves in my hair held all day!! Super easy to use, just section off 4 swaths of hair (use more if you want tighter waves), roll each section of hair neatly around the sponge, then fold each end over so hair can't unravel. Depending on how it sits against your scalp will determine how comfy to sleep on- but since sponges, just play with the angle and you should be super comfy. I love (so does my bf) the beautiful waves it creates in my hair.
