Humidity and Curly Hair: How To Prevent Frizzy Hair

Jan 1

Although curly hair is elegant and multipurpose, it may also be difficult to style, particularly in humid climates. Humidity can cause curly hair to lose its shape and definition and become frizzy, fluffy, and unmanageable. But why does humidity affect curly hair so much, and what can you do to prevent frizzy hair in humidity? This blog will explain the science behind humidity and frizz and share some tips and tricks on how to keep your curls smooth, shiny, and defined, even in the most humid conditions.


What is humidity, and how does it affect curly hair?

When humidity levels rise, they can significantly impact various hair types. This effect intensifies for those with curly hair, often causing increased frizz. That's where specialized  frizz control products can make a significant difference in managing and controlling unruly locks during high humidity conditions.


Curly hair is naturally dry and porous, which means it has gaps and holes in the hair cuticle (the outer layer) that allow moisture to enter and exit the hair shaft (the inner layer of the hair). When the air is dry, curly hair loses moisture and becomes brittle and dull.


This is because curly hair has a higher affinity for water than straight hair due to its shape and structure. The natural oils from the scalp find it challenging to coat the strands of hair with curly hair because of its bends and curves. Compared to straight hair, curly hair is more prone to dryness and damage. In addition to having an irregular protein distribution, curly hair is more elastic and weaker than straight hair. This means that curly hair can stretch and shrink more easily and snap and split more easily.


When curly hair absorbs moisture from the humid air, it causes the hair cuticle to open up and lift, exposing the hair's inner layer to more moisture. This causes the hair to swell and lose shape, resulting in a frizzy, fluffy, unmanageable appearance.


How to prevent frizzy hair in humidity?

Frizzy hair is not bad; you can embrace and celebrate your natural texture and volume. However, if you want to prevent or reduce frizz in humidity, there are some things you can do to protect and nourish your hair and keep your curls smooth, shiny, and defined. Here are some tips and tricks on how to prevent frizzy hair in humidity:


  • Use a moisturizing shampoo and conditioner. One of the most critical steps to prevent frizz is using a moisturizing shampoo and conditioner that can hydrate and nourish your hair. Look for products that are sulfate-free, silicone-free, and alcohol-free, as these ingredients can dry out your hair and cause buildup. Instead, opt for products that contain natural or essential oils, aloe vera, keratin, shea butter, hydrolyzed silk and animal proteins, panthenol and provitamins, and plant extracts. These ingredients can help restore the moisture balance in your hair, smooth the cuticles, and strengthen the hair shafts.


To use a moisturizing shampoo and conditioner:

Wet your hair, then lightly massage a little bit of shampoo into your scalp and hair.

  • Rinse it out thoroughly with lukewarm water.
  • Wet your hair and liberally apply conditioner, paying special attention to the mid-lengths and ends.
  • Leave it on for at least 5 minutes or longer for deeper conditioning.
  • To help seal the cuticles and keep the moisture in, rinse it with cold water.


  • Apply a leave-in conditioner or a serum. To add more hydration, protection, and definition to your damp hair after washing and conditioning it, use a leave-in conditioner or serum. A leave-in conditioner or a serum can also help detangle your hair, reduce frizz, and enhance shine. Look for products that are lightweight, creamy, and moisturizing and that are specially formulated for curly hair. Some examples of leave-in conditioners and serums for curly hair are Kerastase Curl Manifesto Leave-in Cream, Function of Beauty Wavy Hair Leave-in Treatment, and Ouai Hair Oil.


  • Apply a mask with deep conditioning once or twice a week. To infuse your hair with extra moisture and nourishment, consider including a deep conditioning mask in your routine once or twice a week, especially if you have curly hair. This specialized treatment can serve as a targeted curly hair moisturizer, revitalizing and hydrating your curls deeply. Especially for curly hair, this targeted treatment offers a surge of hydration, helping maintain its health and vibrancy. A deep conditioning mask can help repair damage, prevent breakage, and improve the health and appearance of your hair. Look for a deep conditioning mask that is thick, rich, moisturizing, and contains ingredients that can penetrate and strengthen your hair, such as proteins, oils, or vitamins.


To use a deep conditioning mask:

After shampooing and conditioning your hair, generously apply to the wet hair.

Use a towel or shower cap to cover your hair, and let it on for at least 20 minutes—longer for a more thorough treatment. After giving it a thorough rinse, style it as normal.


  • Use a curl-enhancing styling product. You can use a curl cream after moisturizing and protecting your hair to add more definition and shape and hold to your curls. In addition to adding volume and preventing frizz, a curl-enhancing style product helps shield your hair from environmental stressors. Look for a curl-enhancing styling product that is lightweight, alcohol-free, moisturizing, and specially formulated for curly hair. Some examples of curl-enhancing styling products for curly hair are Kerastase Curl Manifesto Gelée Curl Contour, Function of Beauty Wavy Hair Serum, and Ouai Wave Spray.


Apply a tiny quantity of a curl-enhancing styling product to your damp or dry hair, then twist or scrunch it into the desired curl pattern. Let your hair air dry or diffuse it on a low setting.


  • Avoid washing your hair too often. Eliminating frizz from your hair is as easy as not washing it too frequently. Your hair may become frizzy and dry from too much washing, which can strip it of its natural oils and moisture. You can wash your hair as little as once every two to three days, depending on the type and condition of your hair. To remove extra oil and revitalize your hair in between washes, use a dry shampoo like Ouai Super Dry Shampoo.


  • Avoid brushing your hair when it's dry. Another simple way to prevent and reduce frizz is to avoid touching your hair when it's dry. Brushing your hair when it's dry can cause friction and static, making it frizzy and fluffy. Instead, you should detangle your hair when wet, using a wide-tooth comb or fingers. Start from the ends and work to the roots, gently removing knots or tangles. 


  • Use a satin or silk pillowcase or a bonnet. Instead of using a cotton bonnet or pillowcase, use one made of satin or silk to shield your hair and stop it from losing moisture while you sleep. Frizz and friction can result from cotton absorbing moisture from your hair. Satin or silk can help your hair retain moisture and smoothness, reducing tangles and breakage. To keep your curls in place and stop them from getting dirty, you may also tie your hair up in a bun or a scarf made of satin or silk.


  • Use a curl refresher or water to mist your hair. To revie your curls and add some moisture in between washes, you can spritz your hair with water or a curl refresher product, such as Curls Blueberry Bliss Curl Control Jelly or Ouidad Advanced Climate Control Featherlight Styling Cream. This will help you refresh your curls and add some shine and bounce. You can also use your fingers or a comb gently reshape your curls and smooth out frizz.


  • Consume a healthy, balanced diet and plenty of water. You should have a balanced diet full of protein, vitamins, minerals, and healthy fats in order to keep your hair wet from the inside out. You should also drink a lot of water. Water may moisturize your body and hair while aiding in the removal pollutants. Protein can help build and repair your hair.



Humidity and curly hair can be tricky, but it doesn't have to be a nightmare. You can avoid and lessen frizzy hair in humid environments and maintain defined,  lossy, and silky curls by using these tips and techniques. Remember to choose the  right products, wash your hair less often, detangle your hair gently, style your hair with the proper techniques and tools, and maintain your hair with the right.
