UVI Hair Fiber Applicator is the perfect accessory to apply hair fiber perfectly. Designed for precision, this applicator is compatible with UVI HAIR bottles, allowing you to target specific areas where hair fibers are needed the most. Simply replace the original bottle cap with the UVI pump, and with a few presses, evenly distribute the fibers onto thinning or sparse areas. The result is a seamless blend with your existing hair, giving you a fuller, thicker appearance in seconds. For a long-lasting finish, secure your style with a hair spray or similar product.
