Why Does Hair Become Frizzy in Humid Weather?

A humid day can turn your hair into a frizzy disaster as quickly as it takes humid air to draw out all the moisture from your hair's structure. If you've experienced this, you are probably asking why it happened to you.

Why Does Humidity Cause Frizz?

Every person’s hair will absorb the moisture from the air (i.e., humidity). But, if they have a lot of moisture in their air, as in a very hot day; this moisture will act like a sponge and will be pulled upward into the hair shaft, thus increasing the amount of moisture that is in the hair shaft. This change in the amount of liquid in the hair acts as a ballast and thereby, alters – and therefore, the structure of the hair alters. Hair will then become frizzy.

Those who have dry, damaged, or naturally curly hair; will gain the most amount of moisture from humidity, because their hair shafts will absorb more moisture than others. Additionally, hair that has split ends and rough cuticles also makes it difficult for hair to maintain a smooth surface when there is a high level of humidity present.

How Can You Reduce Frizz?

Even though it might not be possible for you to control the weather; there are a number of ways that you can do to protect your hair from becoming damaged from either humidity or heat.

1. Use moisturizing shampoos and conditioners to keep your hair healthy and hydrated.

2. Dry your hair gently and carefully using a microfiber towel, rather than drying with a regular towel.

3. Apply an anti-frizz serum or a light weight leave-in conditioner to your hair before styling.

4. Avoid using heat styling tools, as hair can dry out from too much heat use or exposure.

5. Use a humidity resistant styling product to perform your finished hairstyles.

Regular trims also help reduce frizz by removing split ends that make hair appear rough and uneven. 

Moisturizing Your Hair Is The Best Way To Combat Humidity

One good way to counteract the negative influence of humidity is by introducing moisture back into your hair. Moisture keeps your hair from taking on too much water from the surrounding environment and enables you to maintain the proper moisture level in your hair. If you're able to maintain a good level of moisture in your hair, water from the environment will not have as much chance of entering the inside of your hair prior to being exposed to humid conditions. Therefore, if you continue to properly care for your hair, the amount of frizz that develops in your hair will be substantially reduced.

Conclusion

Humidity and frizz can cause a lot of problems for your hair, but by keeping your hair hydrated, minimizing damage to your hair, and using lightweight, anti-frizz products, you can still have smooth, manageable hair despite the high level of humidity.

FAQs

1. Why does my hair become frizzy only when it's humid?

Humidity adds moisture to the hair shaft, causing it to swell and lose its smooth shape.

2. Is frizz a sign of damaged hair?

Not always. However, dry or damaged hair tends to become frizzier because it absorbs moisture more easily.

3. Can hair oil help reduce frizz?

Yes. A lightweight hair oil can smooth the hair's surface and help lock in moisture, reducing frizz.

4. How often should I trim my hair to prevent frizz?

Trimming every 6 to 8 weeks helps remove split ends and keeps your hair looking healthier and smoother.
