This is 100% human hair and full lace so it's supposed to provide more styling versatility (we'll see). Because it's full lace, I can't really get away with no glue because it just kinda sits weird.
I don't have foundation so I rubbed tinted bb cream on the inside of the wig to match my skin tone, lined around my hairline with gel, stuck the wig on, and used a scarf to press the wig onto the gel. Slept.
Some of it didn't stick, enough of it did to look like a realistic hairline.
