How to Keep Hair from Curling with Humidity

You may feel that hot, humid weather is out to destroy your hair. For many, silky-smooth hairstyles are quickly destroyed when humidity is high because it tends to add unwanted and unruly curl to your locks.

Things You'll Need

• Deep and/or volumizing conditioner
• Antihumectant leave-in conditioner
• Antihumectant spray or serum
• Straightening iron

Instructions

1. Repair your hair, as dry, damaged hair soaks up humidity like a sponge, adding not only curl but also frizz. If you have thick, curly hair, use a deep conditioner every day to both moisturize and smooth unruly curls. For fine hair, volumizing lightweight conditioners are best, as they prevent your hair from looking flat.

2. Apply a leave-in conditioner with the words "antihumectant," "antihumidity," "smooth," or "shine." Make sure you work the conditioner into your damp hair from root to tip.

3. Allow your hair to air-dry, as a blow-dryer, while convenient, robs your hair of needed moisture. Blow-drying your hair only makes it curl more than ever when humidity hits.

4. Seal your hair, once it has dried, with an antihumectant spray or serum. For thick, coarse, curly hair, serum works best; for thin hair, use spray, which won't weight the hair down. After applying the serum on dry hair, you can use straightening irons to get a smooth, silky look that will withstand the humidity.

Tips & Warnings

• Never use a straightening iron on wet hair.

• Never use a straightening iron without first applying antihumectant spray or serum.
