Blink Black Diamond Sealant with mascara wand applicator:
Use after eye-shadow application to spruce up the extensions and return them to a thicker more vivid and luxurious look. Apply directly to the extension bonded area to help protect from oils that break down the bond and cause premature shedding of the extensions.
When used daily, it provides a hold similar to hairspray to help keep the extensions in place all day long.
