Keep styling products to a minimum on straight hair. You want maximum volume without the frizz.

Treatment: Spray Bumble and Bumble Hairdresser's Invisible Oil Primer, $27, onto damp hair and comb through. The primer conditions and protects, but is light enough that you can still build volume.

Styling: Once hair is dry, seal out frizz with a smoothing hairspray like Garnier Fructis Sleek & Shine Anti-Humidity Aerosol Hairspray, $4.29.

A few drops of anti-frizz oil on the ends of damp hair will help to smooth flyaways, and prep for styling.

Treatment: Try L'Oréal Professionnel Mythic Oil Nourishing Oil, $32, a lightweight oil with hydrating avocado and grape seed oils.

Styling: John Frieda Frizz Ease Dream Curls Air-Dry Waves Styling Foam, $8.99, adds hold to loose waves while eliminating frizz.

Look for styling products that enhance curls so you can skip the curling iron. Instead, dry your hair with a diffuser.

Treatment: Wash hair with Living Proof Curl Conditioning Wash and Curl Detangling Rinse, $26 each, specifically developed to treat frizz in curly hair.

Styling: Style with a curl-defining mousse or gel like Kérastase Couture Styling Curl Fever, $37, which will give curls shape and hold, while also smoothing frayed ends.

When straight hair gets frizzy it's a sure sign your hair is in need of major moisture. Use a conditioning product on wet hair, and look for a styling product specifically geared towards treating frizz.

Treatment: Swap out your regular conditioner for a conditioning treatment like Aussie Moist 3-Minute Miracle Deep Conditioner, $5.99, to smooth out damaged hair and re-hydrate.

Styling: Suave Professionals Sleek Anti-Frizz Smooth and Shine Cream, $2.88, can be used on dry hair to smooth frizz and add shine.

An anti-frizz cream that you can apply daily to damp hair will help cure frizz over time, while also treating the immediate problem.

Treatment: Prep hair with Redken Smooth Lock Stay Sleek Anti-Frizz Cream, $16.99, before styling. It's heat-activated and can minimize frizz even after the next time you wash your hair.

Styling: Use Devacurl Styling Cream, $25, which will give hair more curl and hydration with jojoba and wheat protein.
