The Mix: Heat Wave

Summer in Philly means three solid months of hair-wrecking humidity that requires more than a deep-­conditioning treatment to keep locks in line. We’ve found the latest in serious salon frizz-fighting techniques—for curls that need unwinding, to highlighted locks that need soothing—that make those harsh, body-zapping Japanese treatments seem so passé. Go ahead, spend summer outside.
