An attachment for an epilator or an epilator having at least a clamping unit for clamping and plucking hairs that is arranged for driven movement relative to a housing along a hair capture direction is disclosed. The clamping unit has a moveable clamping element having a clamping surface and a hair guiding surface and a fixed clamping element having a clamping surface and a hair guiding surfaced. The moveable clamping element and the fixed clamping element are arranged to be cyclically moveable between an open position in which the two clamping surfaces have a minimal distance such that a gap for receiving hairs is formed between them and a closed position in which the two clamping surfaces abut on each other. The two hair guiding surfaces form a funnel in front of the gap in the open position with respect to the hair capture direction.
