Ok I admit I'm not a veteran wig wearer, so I'll admit that I'm having difficulties keeping my wig cap in place. It ends up sliding off over the back of my head under my wig. is there ways to stick hair pins in it to keep it from sliding? any advice would be great!
Something I do to keep that from happening is to backcomb the hair along my hairline; my hair's really thick/slick, and it's the texture that makes the wig cap slip. Backcombing creates a texture the cap can cling to, and it helps hold the hairpins for the wig in better.
If you believe hard enough in imaginary things, that makes them slightly less fake!
I usually go with the two cap option. The first wig cap I use is one that has two openings, if that makes sense (kinda similar to putting on those sports sweatbands where you pull it down to your neck and draw your hair over it before you pull it back up). After putting that one on, I use a regular wig cap.
I had this problem because my hair is so thick it makes a big lump in the back that pulled the wig cap off. Now I take a whole bunch of bobby pins and pin up all my hair in pin curls. Then I put the wig cap over that to make a smooth surface. While this does take a little time it also is a lot more comfortable and stable. My wig is less apt to slide around than it did otherwise.
