Frizzy hair: 6 tips for styling your hair when it’s very humid

Along with warmer temperatures and the possibility of getting a haircut for the first time in months, summer brings humidity and frizzy hair. For some people, humidity may not be a big deal. But for others, especially those with dry or damaged hair, that humidity causes enough frizz to ruin any plan you had for styling your hair.

Why does humidity make your hair so frizzy?

As anyone with just about any type of hair knows, humidity can be the arch-enemy of your hairstyle (and your skin). “When the weather is humid, the air has a high concentration of water molecules, which are rich in hydrogen atoms,” says Joshua Zeichner, MD, director of cosmetic and clinical research in dermatology at Mount Sinai Medical Center. , to SELF. “These water molecules bind to hair, increasing the number of hydrogen bonds,” which can cause hair to bind and fold in on itself or bind to other hair strands. The result? Straight hair becomes wavy, wavy hair becomes curly, and curly hair becomes even tighter curls.

Any hair type, including straight hair, can become frizzy under the right environmental conditions, but some types are more susceptible. For example, if your hair is already very dry or damaged from over styling, over processing, or using harsh products on your hair, you are more likely to end up with unwanted frizz. Those with curly or fine hair are also more likely to experience it intrinsically, Papri Sarkar, MD, dermatologist at Northeast Dermatology Associates in Boston, told SELF.

Also, if your hair is more porous, you are more likely to deal with frizz. What does this mean, exactly? Porosity describes the hair’s ability to absorb moisture, like the empty spaces in a sponge. If your hair has a high level of porosity, it can easily absorb moisture from the air, Eliut Rivera, founder of Eliut Salon in New York, tells SELF. If you have low or normal porosity, you are less likely to deal with frizz. To find out where your hair falls on the porosity spectrum, simply drop a strand of clean hair into a cup of water and watch what it does. If it sinks right away, you have high hair porosity, but if it seems to float in the middle, you have normal hair porosity, Rivera says.

The good news is that whether you deal with frizz on a daily basis or just once in a while, there are simple tips and tricks you can use to combat that frizz, even on the hottest, most humid days. Here, hairstylists share their best-kept secrets for styling frizzy hair in humidity.

1. Use the right shampoo and conditioner.

It is important to choose hair products that are suitable for your hair type. For example, if your hair is naturally frizzy, you use hot styling tools frequently, or your hair is chemically treated, you’ll need to use a moisturizing and hydrating shampoo and conditioner, New York-based hair colorist Lauren Paglionico and owner of LRN Beauty, says SELF. Her go-to for her clients with over-processed blonde hair is IGK Bad & Bougie Amla Oil Deep Repair Shampoo and Conditioner ($25, Ulta) ($25, Ulta). This duo is formulated with amla oil, which can help hydrate hair and add shine, she says.
