Tame the frizzies. The difference between smooth locks and fuzzy ones is a matter of choosing the right products and knowing the best way to use your blow-dryer.
Add moisture. Your hair turns into a ball of frizz when parched tresses absorb moisture from the air, so deep condition weekly with an oil treatment such as Motions Marula Natural Therapy Strengthening Thermal oil treatment ($7; at mass retailers). Distribute it evenly into dry hair, put on a plastic shower cap and apply heat with a dryer to activate the conditioners.
Seal the cuticle. Stop humidity from penetrating locks with a frizz-fighting serum with silicone, such as Sebastian Professional Liquid Gloss ($17; sebastianprofessional.com). If you have fine, thin strands, use a lightweight cream like Suave Professionals Sleek Anti-Frizz cream ($3; at mass retailers).
Dry with care. How you handle wet hair plays a big role in how it looks when it’s dry. For sleek, straight strands, use a nozzle on your dryer and direct air down toward ends to help cuticles lay flat. To keep curls smooth, twist sections around fingers, then let them air-dry completely, says Pantene Pro-V celebrity stylist Hallie Bowman.
