Humidity equals frizz, and frizz can be the worst.
Just like skin, hair has a natural protective barrier that helps keep essential moisture inside and acts as a shields against the elements. Aggressive cleansers strip curly hair of this barrier, leading to dryness, breakage, and frizz. To keep your curls frizz-free, choose a sulfate-free shampoo and avoid washing your hair every day. Instead, co-wash or simply rinse your hair with water between shampoos, and only cleanse when your scalp is actually dirty.
Like a sponge, hair that’s thirsty will try to soak up moisture wherever it can find it. This means that the drier your hair, the more susceptible it is to absorbing frizz-causing humidity from the atmosphere. Keep your curls well-hydrated by using a hydrating conditioner made specifically for your curl type.
3. An Open Cuticle
Curly hair curving shape means its cuticle layer is naturally raised, with gaps in between the overlapping cells. These gaps allow moisture and nutrients to escape, and humidity to enter and frizz to begin.
To ward off frizz and help curls look healthy, hydrated and shiny, you need to seal the hair’s cuticle. Acid rinse, conditioners and daily moisturizers can help with this, including technology that helps to fill in gaps in the cuticle to defend against frizz.
Damage from environmental aggressors can compromise your hair also. Heat, UV rays, and even friction from combing and brushing also can make your hair weaker and more prone to becoming frizzy. To prevent damage, use a daily leave in moisturizer to protect your hair from sun, styling, and tangles.
Nothing makes curly hair turn frizzy faster than rainforest-like conditions. That’s because humidity disrupts the hair’s internal hydrogen bonds, causing curls to shrink, frizz, and lose their definition. Luckily, the right anti-frizz styling products can also give you great control of the frizz.
