Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions. The hair of the leg is among the kinds of hair that the Lawmaker did not give a rule about. So, the person is free to remove it or leave it. As a result there is no objection to your removing the hair of your leg. For more details, please read Fatawa: 81968 and 81950. Allah knows best.
