Straightening your hair to achieve a sleek, smooth look is no easy task. With all the blow-drying, flat ironing, and fussing that goes into the process, every girl dreads the thought of her hair springing back overnight. From oiling and using the right hair products to sleeping in the most uncomfortable positions at night, you’ve probably tried and implemented different ways to keep your straightened tresses from getting into a tangled mess. 

But has any of you really discovered how to keep hair straight overnight with effective hacks that salvage your luscious locks for the next day? If you’re still struggling and searching, look no more! We’re gonna be sharing our favorite, super-fruitful, and tried-and-tested tips with you so that you can wake up with fresh and kink-free hair, too! Read on to learn more. 

Straighten Your Hair Before Going To Bed

Straightening your hair before bed instead of 2 hours before an occasion is the key to achieving a flawless look. This is because straightening before sleeping allows the style to set and shine compared to setting your hair in the morning when there’s a higher chance of experiencing a frizzy outbreak a few hours later. 

Pro Tip: Make sure to prep for straight hair in the shower, wait until your hair is dry, and use a good heat protectant to avoid damage and guarantee amazing results. 

Opt For A Lower Heat Setting When Straightening Your Hair 

Higher heat settings on blow-dryers and straighteners are for people with thick, coarse, and curly hair. Using an overheated straightener will absorb moisture from your hair, resulting in dry and damaged ends. So when you’re blow-drying, use the cool setting to close the cuticles of your hair and hold in the style for longer. Follow this with straightening your hair according to the temperature guide below: 

  • 148°C for damaged or fine hair 
  • 140°C to 190°C for normal hair
  • 176°C to 204°C for curly hair 

Try Dry Shampoo In Between Hair Washes 

Oily, greasy hair is one of the most common reasons why your straightened hair ends up looking like a messy nest. This is where dry shampoo kicks in as a lifesaver. It absorbs extra oil from your hair, makes it look fuller, and extends the lifespan of your hairstyle. 

We recommend using dry shampoo about one to two times a week. Excessive usage may result in hair loss and scalp issues like infections and acne. Pro Tip: Look for a good quality dry shampoo that doesn’t leave any white residue, so you don’t have to spend the morning brushing it out.

Apply A Small Amount of Hair Oil To Maintain Straightness Overnight 

While this might sound opposite to the advice given above, it is an amazing hack for ladies with dry and frizzy hair. Hydrating your hair with a small amount of good hair oil before straightening is an excellent way to keep your hair straight overnight. A couple of pumps of lightweight oil will help your hair hold its shape and give it a shiny, sleek look the next morning. 

Pro Tip: Avoid water-based products, like spray leave-ins, as they will instantly kink up your hair. 

Minimize Exposure To Humidity For Straight Hair 

Now that you’ve hydrated, straightened, and protected your hair, the question left is, how to sleep with straight hair? Besides using a silk pillowcase for sleeping, avoiding high-moisture environments is equally important. You can use an air conditioner or a fan to keep yourself cool while sleeping or spray your hair with an anti-humidity product. Keeping your hair up and moisturizing it with shea butter will also help. 

Avoid Over-Styling Your Hair 

While it might be tempting to straighten your hair every day, you must remember that just like everything else, your hair needs a break, too. Heating it excessively can cause moisture loss and breakage. So it is best to heat and style your hair only 2 to 3 times a week. Make sure to condition and heat protect your hair beforehand.


You’ve got an elaborate answer for how to protect straight hair while sleeping. Let’s now discover a few more interesting tips and tricks to keep your hair straight and shining! 

What hairstyle will keep my hair straight overnight?

A loose top bun will keep your hair straight overnight. All you have to do is wrap your hair on top of your head and use bobby pins or a claw clip to secure it in place. Unlike hair ties, this trick will prevent your hair from getting any kinks. 

How can I keep my hair straight overnight without heat? 

Since experts recommend straightening your hair only 2 to 3 times a week, styling your hair with other methods that don’t involve heat is a simple and safe way to look and feel your best without damaging your hair. For one, you can blow dry it with cold air — it’s just the heat we are skipping here. Alternatively, consider rolling it with plastic rollers, apply overnight straightening products, or brush and wrap your hair in a satin scarf after showering. Finally, you can also use a volumizing tonic right before bedtime.

Now You Can Keep That Hair Straight

Keeping your hair straight shouldn’t be as simple as tossing in some heat. If you’re after good hair health, begin with making changes in your haircare routine!
