Send frizz and flyaways on a permanent vacation

Beachy waves get all the love this time of year. They're effortless, universally flattering, and won't get disrupted by a little sweat. But what about the girls that aren't into this tousled style? Straight-haired Southerners need some love too—not to mention advice on how to keep their strands sleek and frizz-free. Before you run a flat iron through your hair and simply hope for the best, make sure you're also doing these things to ensure your hair stays silky smooth.

1. Prep Properly

Frizz is caused by a lack of moisture. "When hair isn't hydrated, it allows outside moisture to pass through strands causing them to swell and appear frizzy," explains Chaz Dean, CEO and founder of WEN by Chaz Dean. Because of this, nourishment is crucial. Try mixing a little cleansing conditioner, styling cream, and hair serum together and apply it to soaking wet hair. Doing this before you blow-dry coats each strand with serious moisture.

2. Protect Against Hot Tools

Down South we love our blow-dryers (I mean how else can you get big, bouncy hair when you want it?!), but we do know it's not the healthiest thing for our manes. Try to air-dry hair for as long as possible to cut back on dryer exposure and always use a heat protectant. Look for a formula that also speeds up the amount of time it takes to blow-dry hair (we like L'Oréal Paris's Advanced Hairstyle Blow Dry It Quick Dry Primer Spray).

3. Embrace Serum

"The WEN's Smoothing Glossing Serum is a great tool to keep hair soft and straight. The super concentrated formula is a blend of grapeseed oil for moisture and vitamin A and E to combat damage and frizz," says Dean. Added bonus: It can be used on wet or dry hair. Pack a little travel-sized bottle of serum in your bag to smooth out any flyaways that pop up during the day.

4. Brush With Boar Bristle

If you have naturally wavy or curly hair, but prefer to rock a straighter style, a boar bristle brush needs to be your best friend. Make sure you have a nozzle attachment on your dryer, and then use the brush to smooth out the hair's cuticle. "Keep the dryer moving and use the proper amount of tension [with the brush] to accomplish your desired style," advises Dean.

5. Deep Condition Weekly

"The healthier your hair is, the less frizz you have to deal with," says Dean. Keep your mane in tip top shape by applying a deep conditioning mask, like this one, once or twice a week. On days you don't use it, sleep with a hydrating treatment oil in hair for additional nourishment.
