The cap of a wig is the base material to which the hair, whether real or synthetic, is attached. Applying silicone-based adhesives to the cap keeps the wig in place, holding your natural hair flat and making wig application that much easier, in addition to preventing embarrassing shifts and misalignment.
Skin and Hair Prep
To make your wig sit correctly on your head -- and stay there -- you'll need to prepare its environment first. First, pull your hair back as tightly as it will go. Secure it with bobby pins or a hair tie, depending on your wig and the look you want. Trim or shave away any baby hair near your hairline, since you don't want those showing against a wig of a potentially different color. Finally, wipe down your forehead with rubbing alcohol or astringent, clearing the way for the silicone adhesive to get a solid grip.
Apply a skin protectant -- available from the place you bought your wig or from most major drugstores -- along the area where you want the cap to sit. This is especially necessary if you happen to have sensitive skin. If you want to test the silicone adhesive first, apply a little on your bicep area, leaving it in place for at least a day. If no rash or red spot begins to form after 24 to 36 hours, you're probably in the clear.
Use a cotton ball to apply isopropyl alcohol to the area where the adhesive or tape will be placed. This removes excess dirt and oil from the area, ensuring proper adhesion. Use a makeup brush to apply the silicone adhesive around the area on the hairline where the cap will lay. Some adhesives need to get tacky first -- check out the directions on the back of the jar or bottle before application -- then pull on your wig. Make fine adjustments to the cap, placing the seam at the hairline and visually aligning it horizontally with your eyebrows, then press around the perimeter of the cap. You can also take extra security measures, such as applying wig tape in strategic locations as needed.
Silicone adhesives normally last about six weeks. When you want to remove the wig, you'll need to do so using a specialized adhesive remover. Apply the remover by spraying it liberally over the edge of the cap where it's attached to the glue and your head. Wait a few minutes for the glue to soften. Peel back the edge slightly, applying more remover directly to the joined area with cotton swabs. You only want glue to remain on you, not the cap itself. This applies equally when removing wigs. Snip out stitching if you did this as well. Pull off the cap, including any tape you may have also applied. If you're successful, no glue will remain in the cap's weave.
