Banish frizz for pennies

When humidity threatens a good hair day, whip up this easy leave-in: Add 1⁄4 cup of conditioner and 1⁄4 cup of water into a small spray bottle; shake well and spritz onto damp hair from roots to ends. Conditioner moisturizes heat-parched hair and seals the cuticle so it won’t absorb frizz-causing moisture, nixing flyaways. MONEY SAVED: $20 on anti-frizz serum
