i wouldnt. i feel like the polyester will still suck the moisture out. i went out and bought a half yard each of satin and silk; used the silk for a head scarf and the satin became two pillowcases.
thanks for all the responses... so yay or nay to sleeping without a head tye. I refuse to sleep with a head tie when my bf sleeps over but I also don't want to sacrifice my hair.
eta: also, I sometimes forget to tie my head especially when i'm feeling lazy.
This may sound stupid, but please humor me . I was wondering if wearing silk scarves on your hair would impart protein to your strands. I came up with this thought by thinking of a cast iron skillet. I know that when you cook with a cast iron skillet it imparts iron to your food, so I was wondering if silk did the same for your hair. TIA
