Whether it's to give your hair a break or because your blow-dryer is on the fritz, having to style your locks without the help of a heat styler can be done. Just try one of these hairdo ideas:

Sleek Ponytail

Great for naturally straight hair textures.

Katy Perry Long Straight Blue Updo with a high ponytail

Katy Perry looks radiant in this neon blue and purple high ponytail. Get the look by slicking down the hair on  your head and pulling the lengths into a ponytail. Unless your hair is really wavy, you should be able to get the slick appearance using hair products alone and without having to break out the blow-dryer or straightening iron to mimic straight strands throughout the look.

Rihanna Long Curly Black Updo with a high ponytail
Rihanna works the sleek ponytail look here with ease. Her curly locks have been pulled back tightly at the crown of her head, creating a voluminous cascade of hair at the top.

Charlize Theron Medium Straight Light Blonde Updo with Side Swept Bangs

If your hair isn't long, no worries, you can still rock a sleek ponytail but at the nape of the neck instead of at the crown. And, as Charlize Theron shows us here, it can be worn for both formal and casual occasions. To get this look just part the hair on the side and tie it in a low ponytail.

Taylor Swift Long Straight Updo with a low side ponytail

For a more girlie look, Taylor Swift's low side ponytail is a great option. To get this look, sweep the hair to one side and tie it behind the ear.

Kendall Jenner Long Straight Black Updo with a ponytail

For a cool twist on the sleek ponytail, add elastics to create bubbles in the hair like Kendall Jenner has done here. This works for both a low and high ponytails.

Natural Curls

Great for naturally curly and wavy hair textures.

Curly Shoulder Length Golden Blonde Hairstyle

When you have a natural curl or wave in your locks then it's easy to get a curly look without having to heat up the curling wand. Use curl enhancing styling products and your own hands to twist, curl or scrunch your strands into curls and waves. You can even try braiding your hair and sleeping in it overnight if your locks need more curl encouragement.

Kat Graham Short Curly Dark Blonde Bob

Natural curls on short and medium hair lengths looks great too! Check out Kat Graham's adorable bob here where her corkscrew curls are the main feature.

Medium Curly Dark Red Hairstyle

Have straight hair? Not a problem! You can create this wavy look heat-free by dampening your hair then sectioning it around the head and braiding it. Leave it to air dry (preferably overnight) and you'll have these gorgeous waves in the morning.

Jackie Cruz Short Curly Dark Brunette Shag Hairstyle with Layered Bangs

With the right haircut, curly hair will never require heat styling to perfect it. Jackie Cruz shows off a gorgeous shag cut that works with her curly hair texture flawlessly. This wash-and-go look is chic and easy to do.

Pretty Side Plait

Great for all hair textures.

Selena Gomez Curly Braided Updo with a Side Plait

This look works for any hair texture and all it requires is knowing how to plait or braid your locks. To keep the look fun and modern, side style the plait so it drapes over your shoulder (use hair pins to keep it in place if need be) and keep the finish loose and casual.

Brittany Snow Long Straight Half Up Hairstyle with a Side Plait

Brittany Snow goes for a loose and undone look here with fabulous results. To get this look, take the end of a comb and pull out different sections of your braid for this messy yet oh-so-cool finish.

Paola Andino Curly Half Up Braided Hairstyle with a Side Plait

Glam up your side braid with a bright red lip like Paolo Andino. Her glossy locks have been braided to one side while a few of the front sections have been left out for softness.

Undone Bun

Great for all hair textures.

Vanessa Lachey Long Straight Updo with an Undone Bun

This is another heat free style that can be achieved on naturally curly, straight or wavy hair. Just take your locks in their natural state and pin them into a loose bun at the back of your head. Up high, in the middle or at the nape are fabulous choices and will each create a different finish. You'll also get a different finish based on the texture of your hair. If your locks have a curl or wave to them then the finished look will be soft and romantic. If your strands are straight, you'll have a more structured and professional-looking finish.

Jessica Alba Long Straight Updo with an Undone Bun

For another variation, try a low side bun like Jessica Alba. This is especially good for shorter hair that can't be pulled into a high bun.

Darby Stanchfield Long Straight Updo with an Undone Bun

For ultra long locks, the undone top knot is the ideal option. Leave a few tendrils out to frame the face, and pull out the bun slightly with the tail end of a comb for this soft, undone look.

Katie Holmes Curly Updo with an Undone Bun

Katie Holmes shows us another variation of the undone bun. Take a leaf from her book and pull the hair out to 'bubble' it up at the crown for some gorgeous height. This 'do looks great with and without bangs.

As you can see, heat-free hairstyles look amazing without adding damage to your tresses. For even more heat free hairstyle ideas, check out these videos:
