perfect for my curly hair [SEP] a silk pillowcase is not enough when you live in a dry climate with curly hair that is prone to frizz it is exposed to the elements with minimal protection regardless of the product you use there are still a million other things a woman must contend with such as hormones aging etc that do not help i notice a huge difference with my hair when sleeping with a satin capi definitely recommend for medium thick mid length hair after trying several caps this is the best quality thus far i love the size and after several washes the material is intact and the caps still feel silky i wash these in either the hand wash or delicate cycle in cold water in my machine hang drywhat i do not like roll up the band once or twice this prevents lines from forming on my forehead and the cap stays in place much better
