Since it gives individual hairs space there is no tugging on the skull and subsequently - no headaches! Invisibobble has no metal seal that would cause breakage, instead the ends a soldered together smoothly to protect your mane.Invisibobble can be used with all hair types, no matter if curly, straight, thick or thin. It is water repellent and great for sports or a day at the beach. If not worn in the hair, Invisibobbles make great bracelets!
