ZIMASILK Mulberry silk hair bonnet, 21–23 in

If you want to reduce frizz and breakage overnight, a silk bonnet can make a noticeable difference to how your hair behaves in the morning. The ZIMASILK ZIMASILK 100% Mulberry Silk Bonnet is a double-layer silk night cap with elastic stay on comfort, made to help protect delicate strands while you sleep. It also aims to keep hair feeling smooth, by allowing it to glide over the fabric rather than snag.
