The Hold On Headband features a velvet lining so hair stays in place without pain or pressure. Slide the fastener to tighten or loosen the elastic strap in the back. (Elastic colors may vary.) Each Hold On Headband is one-of-a-kind, repurposed from unwanted textiles. It measures approximately 1.5" (4 cm) wide and fits head circumferences ranging from approximately 21 to 24 inches (53-62 cm). Oh, and it's reversible so you get two different looks!
