4″ Cotton Lycra Headbands. Our soft knit headbands can be worn alone or under any of our hats and scarves. Many use it for Jogging, Yoga Gym etc. The generous size makes them perfect for under baseball caps, as they cover the back of the head! Very useful for Cancer Chemo and Alopecia patients. Those with thinning hair can use it to hold a wig in place. The Headband doesn’t slip from your head and hold the wig stable and secure. Although the skin might be oily and slippery from the hair/skin, our Headbands are the solution for stabilizing the wig on your head.
