POWER hair ties are stronger and thicker hair ties than the ORIGINAL size, which are particularly suitable for thick hair and sports. invisibobble hair loops are best known for their gentleness. They have no metal parts or other joints that can damage the hair. invisibobbles are smooth all over and therefore do not stick to the hair and do not damage the surface of the hair. When the invisibobble is wrapped around the hair, it distributes the pressure on the hair so that it does not only apply to the outer layer of hair. In this way, the pressure on a single hair is significantly less than with a traditional hair tie, and at the same time clear depressions are avoided. Whether your hair is curly, straight, thick or thin - invisibobble is suitable for all hair types! invisibobbles are hygienic and easy to remove from hair
