Winter is the perfect time for straight styles since humidity is low in the cooler months, but as soon as the weather starts heating up and the humidity levels rise, your natural hair begins to revert.

Luckily, there are several ways to keep natural hair straight in humidity, and we’re here with the scoop!

Why Natural Hair Reverts in Humidity

Humidity has the potential to ruin your straight hair days every time – you’re probably aware of that. Have you ever wondered why?

Without getting too scientific, humidity adds hydrogen bonds to your hair, and when these hydrogen bonds break (as your hair dries), your hair’s structure changes. 

Your dry, straightened hair is very much like a sponge, ready to absorb moisture at any moment. So, when humidity comes in contact with your straight strands, the hair immediately starts to drink up the moisture and responds by returning to its natural state.

The more moisture your hair is exposed to, the curlier and frizzier it becomes. Now let’s discuss some basic natural hair rules that you can follow to keep your hair straight.

While moisture is generally good for the hair, especially if it’s been heat-treated, humidity can easily become your enemy. It’s for this reason that hair product manufacturers have developed products to help you combat humid weather.

With the right products and techniques, you can keep your natural hair smooth and straight no matter what climate you live in.

1. Set Yourself Up for Success by Following Best Practices

You can’t expect an inadequate hair straightening job to hold up in humidity. So it’s important to get your hair bone straight from the get-go. Here are some tips to help you do so: 

  • Blow-dry your hair until it’s almost straight.
  • Use the chase method when straightening to get the hair as sleek and straight as possible. 
  • Use a heat protectant to ward off heat-damaged hair. Damaged hair is much less likely to cooperate throughout the straightening process. 

If you’re going with a professional silk press, choose a professional who works with natural hair and knows how to tailor your treatment to your unique hair type. They can get your hair super straight without completely destroying it.

Many professionals who specialize in natural hair styling employ expert techniques and use quality tools and products to deliver long-lasting results. 

Although, it is important to understand that using heat on your hair (even if done by an expert) will significantly increase the likelihood that you’ll experience heat damage.

2. Implement Touch-ups With Your Flat Iron

There will be times when humidity does a number on your hair despite your best efforts – that’s when you should consider doing a touch-up with a flat iron.

Flat irons are generally frowned upon in the natural hair community, but if you straighten mindfully, you can keep your hair sleek in the presence of humidity.

The trick is to touch up only the areas that need it and use a heat protectant before using any heat on your hair. Again, the goal is to avoid heat damage, if possible.

It’s also essential to apply some form of hydration to your hair after using the flat iron. The hydration could come in the form of a styling oil, a hair spray, or an anti-frizz serum specifically formulated to tame flyaways and frizz.

Just make sure that the hydrator is not water-based, or it’ll cause your hair to revert to its natural texture.

Try not to touch up your hair more often than once a week. Even if you like to keep your hair styled all the time, remember to give your hair a break from time to time and put its health first.

Touching it up every day could quickly result in heat damage, extreme dryness, and eventually breakage. 

Pro Tip: Try to only straighten the areas around your part and hairline – let the other hair do its thing. The less heat you use overall, the lower your risk of hair damage.

3. Wear a Bun on Humid Days

On days when humidity is high and your hair is at high risk for frizz, put it up into a bun and go ahead with your day. The purpose of the bun is to shield the majority of your hair from the humidity, and it works really well in most cases.

Go for a loose bun that can easily transition from day to night and glam it up a bit with accessories. You can always unravel your bun and shake your hair out to wear it straight once you get to your destination.

You may live in an area where mornings are more humid than evenings, in which case you can tie your hair up in the morning and let it down in the afternoon. 

4. Be Realistic

Everyone wants their hair to look Insta-perfect at all times, but that’s impossible. We will all have our bad hair days. If you expect your hair to be bone straight for weeks in high humidity, you will likely be disappointed. Always be realistic and learn how to adapt to weather changes whenever possible.
