Standard hair rings apply even pressure on the hair, leaving a noticeable mark; when this hair ring is wrapped around the hair, it applies uneven pressure around the ponytail's circumference. The invisibobbles' uneven pressure distribution makes it possible to securely hold hair in a ponytail without going overboard. As a result, the ponytail has more space between the individual hairs than it would with a typical hair band. Invisibobble Power was created especially for thick hair buns.
