1. Dry your hair with a diffuser. These cost $6 and up depending on the brand, and they conveniently attach to your hair dryer. Make sure to keep your dryer on a cool setting, because one of the easiest ways to allow humidity to wreak havoc on your hair is by applying too much heat. If you can, let your hair air-dry.

2. Apply styling cream immediately after washing hair. This is especially important for girls with curly or coarse hair. If you want to keep your natural texture, apply it right after you wash your hair and dry it with a diffuser. This creates a protective layer against frizz. Try a curl cream likeL'Oréal Paris Advanced Hair Curve It Curl Taming Cream.

3. Use a deep-conditioning treatment once a week. Heat mixed with humidity can severely dry out your hair, so deep conditioners and hair masks are a must. Anything that is oil-infused works wonders for eliminating frizz. Try Neutrogena Triple Moisture Deep Recovery Hair Mask.

4. Use a protein-infused conditioner. These types of conditioners help repair dry, damaged hair and protect it from humidity at the same time. Try Organix Smooth Hydration Argan Oil and Shea Butter Conditioner.

5. Don't wash your hair more than twice a week if you have thick, curly, or coarse hair. Too much washing strips the hair of its natural oils, which can make it dry and frizzy. If your hair gets too oily, you can substitute regular shampoo for a dry shampoo.

6. Don't go for blunt haircuts. When your hair is cut evenly all around, it creates too much volume at the bottom, especially when it comes to curly, thick, or coarse hair. Go for a medium to long cut with layers. Your layers should start around your lip and gradually angle back. Try long-layered cuts like Shakira's and J.Lo's.

7. Comb your hair while in the shower — never while it's dry. Applying a dry brush against dry hair can create fullness and puffiness that you wouldn't want in the summer. Brush your hair using a wide-toothed comb in the shower while it's conditioned, then rinse. If you need to untangle it a bit while it's dry, try combing through it with your fingers.

8. Don't towel-dry your hair. This actually causes more frizz. Instead, squeeze excess water out and allow it to air-dry or use a diffuser.

9. Apply a shine serum to the ends of your hair. Your ends tend to look drier in the summer months, so use a serum, like Biolage Smooth Proof Serum, while it's still wet.
