(a) The license shall be renewed on or before the thirtieth day of April, 1962, for a period of two years and biennially thereafter, and the holders of said licenses shall pay to the department a fee to be determined by regulation for renewal. Any holder of a license who shall fail to apply for a renewal of his or her license and who continues the practice of barbering or any of its branches, shall, on conviction thereof in a summary proceeding be subject to a fine not to exceed three hundred dollars to be collected by summary conviction as like fines are collected by law, or to undergo an imprisonment for a period of not more than ninety days, or both. Any such person shall have the right of appeal, as in other cases of summary conviction.

(b) A barber who is not engaged in the practice of barbering may request the board, in writing, to place his or her license in escrow and thus protect his or her right to obtain a license at such time within a five-year period as he or she may again become engaged in the practice of barbering.

(c) Any person who fails to renew his license or has escrowed his license for a period of five years without renewing his license shall, prior to receiving a license, submit to and pass an examination appropriate to the license being sought.
