Hot, humid days are perfect for hitting the beach—not so much for keeping your hair smooth. Here's how to maintain control, no matter the weather.
Only Lather Up a Few Times a Week
"The natural oils that accumulate are good frizz fighters," says hairstylist Nathaniel Hawkins. If your hair feels oily, use a dry shampoo, like Batiste Dry Shampoo Original, between washes.
Unless your hair is extremely fine, use a deep conditioner each time you wash, and be sure to leave it on for at least five minutes. Frizz happens when dry, porous hair sucks up moisture in the air, causing the shaft to swell. This heavy dose of conditioner coats the hair shaft, making it harder for moisture to sink in.
Don't Towel Dry
It roughs up the hair's cuticle so that it won't lie flat, which makes it look frizzy. Instead, use a superabsorbent microfiber towel to gently press the water out of your hair.
Buy a Souped Up Blow Dryer
Apply a Gel or Serum
We've all experienced that sensation when we step out into the humidity and our hair begins to grow and expand with frizz. This "smart" gel is formulated with heat-activated wheat protein that breathes in humidity, protects the hair shaft and prevents hair from expanding.

Use a Curling Iron
It may seem counterintuitive if you already have naturally curly or wavy hair, but wrapping a couple frizzy strands around the iron will help noticeably smooth and shape them. Air-dry first to "give your hair a little body, which is the perfect foundation," says hairstylist Adir Abergel.
Do a Weekly Hot-Oil Treatment
It's not as heavy as a mask, so it won't weigh hair down. Choose one with jojoba oil (such as Queen Helene Jojoba Hot Oil Treatment
to help strengthen the cuticle and further prevent frizz. Just be sure to apply it below your ears only so the crown doesn't get too flat.
Lightly mist a shine spray (such as Moroccanoil Glimmer Shine Spray)
onto a spooley or large toothbrush and lightly skim it over the hair to grab individual, untamed strands.
