The One Anti-Frizz Product You’ll Need All Summer Long

With chemically-treated hair that I iron straight daily, keeping it under control on humid days is an uphill battle. But rest assured, there is something to tame the puff and frizz whether you let your hair dry naturally or with a blow-dryer. Apply NuNaat Curly Hair Leave-On Treatment ($6.99) on wet hair before you style to keep hair frizz-free and silky soft all day without looking oily.

And it isn’t just for curly hair – this keratin-based Brazilian miracle in a bottle works on straight hair, too. If you do air dry, NuNaat will restore your hair’s natural texture (no matter how often you color or straighten it) and add the perfect amount of body. At under $10, stock up – get one in your beach bag, your bathroom cabinet etc. Then the next time the thermometer enters triple digits, you’ll at least be covered in the hair department.
