This is the method I use to stain the scalp on a silk closure. Most silk closures come with a scalp that is almost white. In order to make the closure look as natural and realistic as possible, the scalp color should match your natural scalp color or your forehead color. In order to get that color match, I stain the silk/lace on my closures. This method also works for lace closures, but the mixture should be much more diluted.
