Living Proof Straight ($29)

This straightening product harnesses the power of Living Proof’s patented molecule, OFPMA, to repel humidity, dirt and oil and prevent breakage. It’s also formulated without oils, resins or silicones, so you can actually reapply it over and over again without any product build-up. That means you can also use it as a heat protectant for touch-ups, or even as a dry shampoo.


Joico Humidity Blocker Finishing Spray ($18)

There’s nothing that will ruin a good blowout like a sticky, humid day, which is when this spray comes in handy. All you have to do is lightly spray it on your hair after you finish styling and it will create a physical shield against humidity and fight frizz. By also providing a light hold, this straight hair product will give your style some serious lasting power.


UNITE LAZER Straight Relaxing Fluid ($26)

Cut down your blow-dry time with this relaxing fluid. It works on fine, medium and thick hair, and can help make even the curliest hair sleek and straight. As an added bonus, it smells like sugar cookies!

Pureology Super Smooth Relaxing Serum ($24)

Sure, this serum helps cut down your blow-dry time, but what makes this one of the best products to keep hair straight is that it helps preserve your hair color. And, the fact that it’s lightweight, fights frizz and also adds shine, definitely makes it a worthy tool to add to your styling arsenal.

Fekkai Brilliant Glossing Crème ($20)

If your hair is especially frizzy, then this cream may be the answer to your prayers. It contains encapsulated olive oil spheres that keep out humidity, tame frizz and add lustrous shine that will last all day. Just remember, a little bit goes a long way.
