How to Keep Hair from Curling with Humidity

Method 1 of 4: A Good Foundation

Regardless of your hair type, there are a few important steps to lay a solid foundation for styling your hair. These are all important for minimizing the negative effects of humidity.

1. 
   1
   Dry Completely: It is important that your hair be completely dry before entering a humid atmosphere. If you leave your house with damp hair, it will continue to absorb moisture from the air and become limp or frizzy. When your hair is totally dry, it acts as a barrier to keep from taking in unwanted moisture. 

2. 
   2
   Dry Naturally: Although blow-drying hair appeals for those of us in a hurry, the heat from the dryer fries the ends of hair. These cooked ends become kinky and frizzy in humidity, giving that unwanted "puffy" look. Instead, let hair air-dry naturally. Try showering at night and going to bed with your hair wet to help expedite your morning styling routine.
3.

   Avoid Excess Oil: Increased temperatures means that your body correspondingly increases the amount of oil it produces in your hair. When your hair is greasy, it takes longer to dry and attracts more moisture. To prevent this, wash your hair regularly and make sure it is adequately moisturized.

Method 2 of 4: Naturally Curly

1. 
   1
   Avoid brushing: Curly hair has more natural volume than straight hair, and brushing it can produce more lift than is wanted. Combined with humidity, it can get especially out of hand. Instead, break up knots and tame your mane by finger-brushing curly hair. This aids in avoiding both breakage and frizz.
2. 
   2
   Heat-Straightening: If you decide to use a flat iron to straighten your hair, be sure that it has cooled completely before you leave. When using a flat iron, your hair is still malleable from the heat for several minutes afterwards. During this time, if you enter a humid atmosphere, it will respond to the humidity more than if it were cooled. To avoid this, try straightening your hair as the first step in your morning routine, so that it has cooled completely before you leave your house.

   Layers: If you intend to keep your curls, consider cutting your hair in a style with many layers. They will help to enhance natural curls yet minimize frizz.

Method 3 of 4: Naturally Straight

1. 
   1
   Avoid Heat: Straight hair is easily damaged by heat, but hard to cover up. When possible, avoid straightening or blow drying your straight hair. This will help to keep the ends intact and kink-free.
2. 
   2
   Avoid Layers: Haircuts with layers enhance curls; not what you want. Instead, choose hair cuts that are blunt and long. The longer the hair, the heavier it is, making it less likely to curl in humidity.
3. 
   3
   Wash Regularly: Fine hair that is also straight is particularly prone to a limp, frizzy curl in humidity. This is a result of a faster build-up of natural oils, which responds to moisture more quickly than thick hair. To make sure your fine hair looks fresh, wash daily or once every two days.

Method 4 of 4: Helpful Products

Sometimes, more than just a good wash and dry is necessary for keeping hair beautiful in humidity. To aid in keeping your locks shining, try some of these helpful hair products.

1. 
   1
   Dry Shampoo: Dry shampoo can be a great investment for those who don't have much time to spend styling hair. Instead of washing hair daily, use dry shampoo to absorb excess grease and grime on the go. Tight budget? Baby powder works as a great substitute. Sprinkle a little along your scalp and massage into your hair to completely disperse the powder.
2. 
   2
   Deep Conditioner: Many times hair gets frizzy because it is not moisturized well enough. Try using a deep conditioner every day to assist in giving your hair all the moisture it needs, so it doesn't try to absorb more from the atmosphere.
3. 
   3
   Hair Spray: A classic go-to, hair spray is a great tool in blocking out humidity. Giving your hair a light coating acts as a shield to moisture, keeping your locks lovely. Concerned about looking stiff? There are many hair-sprays available that still allow for flexibility in your style.

   Straightening Serum: A light-weight serum can be used on dry hair to manage fly-aways and keep strands straight. It can also be used in damp hair to help it dry straight and frizz-free.
