Not for CPAP users! [SEP] I am a new CPAP wearer while sleeping. Sadly my head gear started breaking my hair off. I did some research and many women who use cpap’s suggested “silk” night cap or head wear. I thought I would try these because they have a silky material inside, and are adjustable. However, by headgear slips right off if I have this cap on. Plus they make my head too hot. Maybe they’ll be great to wear in the cold winter months.
