Hot, humid hair can make all kinds of hair frizz, but it's especially troublesome if you have curly hair. We asked experts from New York City's top salons to reveal their frizz-free secrets:

• Twist your curls. After using a moisturizing shampoo and deep conditioner, comb hair and towel dry. Apply a gel all over, then begin twisting hair by wrapping sections around your finger. You don't want a uniform look, so twist thick sections of hair and very small sections next to each other.

• Finger-comb hair. After applying moisturizing conditioner in the shower, comb it with a wide-tooth comb while sopping wet. Apply styling product (gel or mousse) and finger-comb hair. Don't brush it!

• Don't handle hair. Once your hair is dry, don't touch it. (Handling dry hair can create frizzies.) If you need to freshen up, arrange your curls carefully and lightly with your fingers. Or, apply hair spray and gently scrunch hair to invigorate curls.

• Keep moisture out. The reason hair goes crazy in humid weather is because the moisture in the air moves into the hair and expands the hair shaft. If your hair is full of conditioner it's more difficult for moisture to enter. Use a weekly hair treatment throughout the summer to keep hair well-conditioned. Always use a moisturizing shampoo and conditioner. If your hair is thick, try using a leave-in conditioner.
