Here too a decreased curve index was observed in the finger subject to greater trauma [10]. Increased forces on a nail bed also likely change the rate of nail growth. The rate of growth on the nails of an individualâs nondominant hand is slower than the rate on the dominant hand, which is subject to more trauma [6]. Similarly, it has been noted that onchycophagia, a habit commonly known as nail biting and observed even in chimpanzees, increases the rate of nail growth [1,11].
