rizz is mostly caused by a lack of moisture in your hair, but humidity can also contribute to it. Your hair loses moisture throughout the day, so midday, the cuticle [the outermost layer on your strands] opens up and lets the outside air in, creating a frizzy mess.
Choose a sulfate-free, glycerin-packed shampoo.
Look for one with glycerin high up in the ingredient list (the closer ingredients are to the top of the list, the more concentrated they are), since it helps combat frizz by penetrating the hair shaft and hydrating it from the inside out. It also creates a protective coating over the outside of the hair shaft so it doesn’t break, says Townsend.
Don’t skip conditioner.
It’s all about depositing moisture in your hair, or else the cuticle will open up to let moisture in and turn your hair from smooth to frizzy. So, look for a conditioner that contains glycerin as well as other hydrating ingredients (like shea butter), and apply it from midshaft down to your ends, keeping it away from your roots if you’re worried about it weighing down your hair.
Twice a week, only use conditioner on your hair instead of shampooing it.
You might think your hair needs to be shampooed several times a week, but it doesn’t. Every two days, apply conditioner instead of shampoo and then rinse it out. Conditioner contains a small amount of surfactants (what shampoo uses to cleanse your hair), so it will clean it without stripping your hair of its natural oils.
Let your hair dry 90 percent of the way before you blow-dry.
Too much hot air focused directly on your strands dehydrates it, making it frizzy — especially during the winter months when the air is less humid. If you have straight to slightly wavy hair, let your hair air dry 90 percent of the way, Garrison says, and then use a dryer on it for the last 10 percent.
De-frizz wavy hair by putting it in a bun after it’s dry or defining your waves with a curling iron.
After you’ve shampooed, conditioned, and applied the dry oil from ends to midshaft, blow-dry your hair, and either put it in a bun if you want looser waves (the frizz-fighting happens as your hair cools, when your cuticle locks into place) or define your curls with a barrel iron. Townsend says the heat will keep the frizz at bay.
If you get caught in the rain and your hair poufs out, hair serum will be your BFF.
Apply to finer hair (or a cream or oil formula for textured hair) over your fuzzy trouble spots and secure it into a bun while it’s still damp to smooth it back down.
Use hand or body lotion to tame a frizzy ponytail.
If your hair is in a ponytail and the sides start to frizz up, smooth them down with hairspray. But if the back of your pony turns into a frizz ball, squeeze some lotion into your palms, rub them together, and gently run your fingers through your hair to make it look polished.
Sleep in a silk scarf if your hair is super textured.
To keep your cotton pillowcase from sucking up all the moisture in your hair, wrap it up at night in a bun, and then tie on a silk scarf, which will retain moisture, says Stephen.
