BaBylissPRO Expandable Sectioning Clips are hinged clips that open wide at the centre to grip thick or heavy sections of hair, built for keeping hair separated during cutting, colouring, or blow-drying. Unlike a standard flat duckbill clip, the expanding hinge lets each clip hold more hair without slipping down toward the ends, so sections stay put through longer services. The lightweight plastic housing won't weigh the hair down while it's clamped, and the clips are reusable. They're built for isolating larger sections on medium to long hair; very fine or short sections may hold better in a smaller clip instead.
