Fairy LiceMothers' MagicWand (Nit Free Terminator Comb) is made of tempered steel. It's the #1 Nit Removal comb on the market. Long metal teeth help drag nits out of the hair using micro-grooving and rounded ends to protect the scalp. The "micro-grooving" on the teeth consist of microscopic cutting edges that are positioned in a tight spiral form. With thorough combing, these cutting edges along with the dragging action of the teeth remove even the tiniest nit. Also uses anti-slip bands to allow for better gripping and control. To aid in the nit removal process, Fairy LiceMothers' MagicMousse is highly recommended.
