Tame your tresses with Ouidad’s Climate Control Gel, a product that shields hair from humidity, leaving strands smooth, defined and controlled. Fans of the cult-favorite line swear by Climate Control to keep curls intact or prolong their blow-outs. To use, simply apply a dime-size amount to towel-dried hair, and style.
