When you have curly, coily, or wavy strands, rocking straight hair usually means spending some quality time with your flat iron. While the results can certainly be worth it, frequent use of hot tools can take a toll on your strands and contribute to dryness, split ends, and breakage. Fortunately, ironing your mane isn’t the only way to get straight strands. In fact, there are plenty of straightening techniques that don’t involve subjecting your hair to high temperatures. While these approaches may be slightly more time-consuming than running over your tresses with a ceramic straightener, the payoff—sleek, shiny, and healthy-feeling hair—is well worth it.
If you’re ready to retire your flat iron (or at least give it a nice long break), keep reading. Ahead, we’ll explain how to straighten hair without heat and share tips on keeping your strands silky, smooth, and frizz-free.
What Causes Hair Damage When Straightening?
Any heat styling can damage your hair, but certain straightening habits can make it far more likely you’ll develop concerns like dryness, breakage, and loss of shine. Here are the most common mistakes that contribute to visible heat damage:
- Excessive heat exposure: Exposing your hair to high temperatures can cause cracks to develop in your hair’s cuticle (its outermost protective layer). The more cracks there are, the quicker your hair loses moisture, and the weaker it gets.
- Lack of heat protection: It’s always a good idea to apply a quality heat protectantbefore drying, curling, or flat ironing your hair. Skipping a heat protectant leaves your hair directly exposed to high temperatures with no buffer, increasing the likelihood of damage.
- Poor-quality tools: Low-quality flat irons often heat unevenly or lack accurate temperature controls, increasing the risk of hot spots that scorch sections of hair.
- Repeatedly straightening the same sections: Running the iron over the same section of hair multiple times can compound heat damage. Instead, set your iron to the lowest heat setting possible to get the results you want in one or two passes.
- Straightening damp or wet hair: Using a flat iron on hair that isn’t fully dry can cause the water inside the strand to heat rapidly and expand, leading to internal damage. Always make sure your hair is completely dry before ironing your strands.
Can You Straighten Hair Without a Flat Iron?
Right now, you’re probably skeptically wondering, “How do you straighten hair without heat?” We get it: Flat ironing is usually presented as the only way to achieve sleek, straight hair—but that’s not actually the case. There are plenty of ways to make your hair sleeker and smoother without relying on hot tools, and as with most things in haircare, the best approach depends on your hair type and texture.
For example, if frizz is what’s standing between you and straight strands, updating your routine with products to flatten hair can help keep your strands silky and sleek. Those with wavy or curly hair may see better results by wrapping their hair before bed. And nearly anyone can straighten their hair using a blow dryer set on cool or warm—though it may take a little elbow grease. Ultimately, when it comes to scoring straight hair, it’s all about finding the technique that works best for you.
How To Straighten Hair Without Heat
As mentioned, there are plenty of ways to straighten your hair without heat. Here are seven of our favorite time-tested methods that actually work.
1. Use smoothing haircare products
If your hair is already somewhat straight but tends to get frizzy or slightly wavy throughout the day, consider updating your haircare routine with smoothing haircare products. Using products designed to help combat frizz can help keep your mane looking sleek, shiny, and straight without the need for hot tools.
To start, we suggest swapping out your go-to shampoo and conditioner for a smoothing duo, such as the L’Oréal Paris EverPure Sulfate-Free Iron Sleek Smoothing Shampoo and the L’Oréal Paris EverPure Sulfate-Free Iron Sleek Smoothing Conditioner. The humidity-fighting formulas control frizz all day and help boost shine for glossy, healthy-looking strands. Then, once weekly—or as needed—tame your hair with the L’Oréal Paris EverPure Sulfate-Free Iron Sleek Coat Treatment. This unique, semi-permanent treatment coats the hair fibers to lock out frizz, with results lasting for up to five washes. To use it, spray the formula evenly onto clean, damp hair, then blow-dry with tension to activate the product. Keep damage to a minimum by setting your blow-dryer to cool or warm, instead of hot.
2. Wrap your hair overnight
One of the easiest ways to straighten hair without heat is to wrap your hair at night. This technique involves brushing your hair to remove tangles, then wrapping it tightly around your head, pinning it in place, covering it with a silk scarf to help ensure a smooth, sleek finish come sunrise. It’s easy to do and effective, particularly for those with wavy hair. Head on over to our article, How To Wrap Your Hair At Night, to learn the ins and outs of this simple straightening technique.
3. Wet wrap your hair
Wet wrapping is another effective way to straighten hair naturally, and unlike dry wrapping, wet wrapping works well for curlier textures. The process is similar to dry wrapping, except it (unsurprisingly) involves pinning your hair flat while it’s damp, then letting it dry in place. If your hair is prone to frizz or flyaways, apply a smoothing leave-in before wrapping your hair for a sleeker, shinier finish. We recommend the L’Oréal Paris Elvive Dream Lengths Frizz Killer Leave-In Serum, which helps tame frizz and static for smooth, silky-looking strands.
4. Blow-dry with cool air
If you’re looking to get straight hair quickly, heatless blow-drying may be worth a try. As the name suggests, this involves blow-drying your hair with your dryer set to the cool (rather than warm or hot) setting. It’s a simple trick that helps reduce the risk of heat damage while leaving your hair shiny and smooth.
Start by detangling your hair with a wide-tooth comb to remove knots and minimize breakage. Next, work a leave-in conditioner through your strands to help lock in moisture and boost shine (we love the L’Oréal Paris EverPure Sulfate-Free Moisture 21-in-1 Leave-In Conditioner). Let your hair air-dry until it’s about halfway dry, then divide it into two to four sections, clipping the sections you’re not working on out of the way. With your dryer set to the cool setting, dry the first section, using a boar bristle brush to smooth from roots to ends as you go. Repeat on each section until your mane is completely dry and straight.
Editor’s note: Because it uses cool air, this method will likely take longer than a standard blowout. Factor in a few extra minutes before trying this hack on a busy morning.
5. Use extra-large rollers
When you’re thinking about how to straighten hair naturally, rollers probably aren’t top of mind. But when chosen correctly, this classic beauty tool can help you achieve sleek, straight strands with zero heat. The key is using very large rollers, so your hair isn’t wrapped around them multiple times—that repeated wrapping is what creates curl.
Start by shampooing and conditioning your hair as usual. Detangle your tresses, then spritz your strands with the L’Oréal Paris Elvive Glycolic + Gloss High-Shine Leave-In Serum to smooth your hair and boost shine. Create a one-inch section of hair and place an extra-large roller at the ends, rolling it up toward your roots. Secure it at the crown with a clip and repeat the process until all of your hair is rolled up and secured. Leave the rollers in overnight (or until your hair is completely dry), then unravel to reveal a bouncy, heat-free ‘90s blowout.
6. Try the banding method
Banding is a popular natural hair technique typically used to stretch tight coils and prevent shrinkage—but with a few tweaks, it can also be used to straighten hair without heat.
Start by parting your hair straight down the middle and clipping one side out of the way. Divide the loose side into three smaller sections. Beginning with one section, secure a hair elastic as close to the roots as possible. Continue placing elastics down the length of the hair, spacing them slightly apart, as if you were creating a tight bubble braid. Repeat on the remaining sections, then move on to the other side of your head and do the same. Leave the elastics in overnight. In the morning, gently remove them and comb through your hair with a wide-tooth comb to reveal straighter, elongated strands.
7. Do a slicked-back bun
If your hair falls somewhere between straight and wavy, wrapping it into a twisted bun can be an easy way to smooth out your natural wave pattern and achieve sleek hair without heat.
Start with damp (not dripping) hair and create a low ponytail at the nape of your neck. Twist the ponytail once or twice, then wrap the lengths around the base to form a tight low bun. Secure it with a silk or satin scrunchie to help prevent creases, and let your hair dry completely. Once dry, unwrap the bun and brush through your hair to reveal straighter, smoother-looking strands. If needed, apply a leave-in cream, such as the L’Oréal Paris Elnett Anti-Frizz Slick-Back Hair Styling Cream, to tame any errant frizz or flyaways.
How To Maintain Straight Hair
Once you’ve successfully straightened your hair without heat, you’ll probably want it to last as long as possible. A few tweaks to your routine can ensure that it does. To start, avoid getting your hair wet or subjecting it to high humidity—moisture can cause your hair to frizz or revert to its natural wave or curl pattern, even with a solid straightening technique. It’s also a good idea to avoid putting your hair up into tight ponytails or buns, as tight hair elastics can create a “dent” in straight strands and sabotage your sleek style. If you do need to put your hair up, twist your lengths and clip them up with a large claw clip.
Finally, if you want your straight hair to last overnight, you’ll need to take a close look at your bedtime routine. Consider swapping out your cotton pillowcases for a silk or satin alternative to minimize frizz-causing friction, and wrap your hair before hitting the sheets to keep your smooth, straight style intact.
How Often Can I Naturally Straighten My Hair?
If you’re not using heat, you can straighten your hair as often—or as infrequently—as you choose: Heat is the problem, not sporting straight strands. Still, it’s a good idea to give your hair a rest every now and then to avoid over-manipulating your strands. On rest days, embrace low-tension hairstyles like a loose ponytail, messy bun, or flowy braids to give your strands and scalp a break.
