Evolution Hair Salon
Evolution Hair Salon's beauty savants cut, coif, and color tresses at their Lincoln Park spot. Ornately framed mirrors cast back images of clients' newly titivated locks and occasionally reflect on whether it's time for any of the salon's other services, including hair extensions and makeup applications.
