John Frieda, who brought us the miracle of Frizz-Ease, takes one step closer to being a style saint by establishing HAIRraising, a campaign benefiting Children's Hospital Boston. A cut-a-thon kicks off the monthlong event on April 25, when top salons across the country discount their services, with proceeds going to CHB. Need style inspiration? Try sexy waves like the ones created by John Frieda's Luigi Murenu at Valentino (right). Visit hairraising4chb.org for a participating salon near you.
