I used to have a polyester bonnet and it was one of the causes of my oily scalp. I was hesitant to buy this because it’s so expensive but I’m glad I did. It’s very thin and breathable, and can be adjusted. I hate having to hand wash it. Also can’t give 5 stars because it doesn’t seem like it would last a few years…
