Hey, INH babes 💕 It can be intimidating at first to curl or straighten synthetic hair, but fear not — it's not as complicated as you would think! Your INH Hair INFINI-FLEX™ hair is high heat resistant, so if you follow the steps below you can customize your wigs and extensions in no time.
We're answering your FAQs with the best tips for how to use heat on synthetic hair. Let's get into it...
Can you put heat on synthetic hair extensions?
Yes — but with caution.
When curling your INH synthetic hair pieces (synthetic wigs, clip-in ponytails, hair extensions, etc), we recommend you do not go above 320 degrees Fahrenheit to keep your synthetic strands looking healthy & luxurious.

Can you use heat protectants on synthetic hair?
Yes! And you absolutely should!
Just like with your own hair, it's super important to use heat protectants to create a barrier between the hair fibers and your hot tools to prevent heat damage.
We recommend using Flame Fighter heat protectant spray — she adds that extra barrier between the heat & your strands.. plus, she nourishes your hair & fights off frizz while she protects it from damage.
Use the Heat Heroes to extend the life of your hair and protect it from heat damage before and after styling.
How do I curl my synthetic hair?
If you are interested in curling your synthetic pieces, we recommend you curl them before applying to your head. Use the Claw Clip or Pins and attach to a towel rack or something stable to make the job a lot easier.
Curl your synthetic hair in uniform sections. If using a wand, gently wrap the hair around the wand and hold for a few seconds until warm. Then drop the curl into the palm of your hand & let sit in a coil to cool for a few seconds and set before dropping the curl, this allows the hair to set permanently. Repeat this step for each curl until complete. If you want to comb or brush out the curls for a voluminous blowout look, wait until the very end once your curls have fully set and cooled.
When curling heat-resistant synthetic hair with heat, just know the original pre-styled texture of your wig or hair extensions will be permanently erased. The hair will remain in the new curly, wavy, or straight style you have created with your hot tool.

Pro tip: Smooth down any frizz or flyaways with hair styling tools like Quick Slick & detangle and revive your synthetic hair in seconds with Emergency Revival Spray.
How long will my heat styles last on my synthetic hair?
The good news is once you curl or straighten your synthetic hair, it will last forever. It's essentially the ultimate lazy girl hack.
If you straighten or curl your hair pieces, our INFINI-FLEX™ technology will remember that new style. *Please use caution as this means the original style will be forgotten after hot tool use.
Can I heat my pre-styled synthetic pieces?
Technically, yes! But BE CAREFUL. If you heat style your curled or texturized hair pieces, the original style will not bounce back like it does when you spritz or wash her sans heat.
Each time you use heat on your synthetic hair it will erase the old style and hold on to the new style. We don’t recommend using heat on your hair pieces multiple times because it can be damaging to the quality of the hair (just like your own hair).
If you have not used heat on your hair pieces, you can revive the original texture by simply spritzing with water or Revival Spray and shake to snap her back to looking new.
If you want to limit the amount of times you wash your hair pieces (we recommend only doing so when absolutely needed) you can spray her with dry shampoo to deodorize, de-oil, and freshen her up.
Can I straighten my synthetic hair?
Yes, and we created the step-by-step to get a sleeker look here!

What Temperature Can You Use to Heat Style Synthetic Hair? (Safe Heat Settings Guide)
Synthetic hair reacts in its own way to styling tools. Safe heat settings make the difference between a style that lasts and one that falls flat fast.
Many users check the INFINI-FLEX synthetic hair guide for background on how different fibers behave under warmth. Start low and increase slowly. A quick test on a small hidden strand shows exactly how the piece handles the tool.
Lower levels often create smoother results that hold without extra stress on the fibers.

Watch how the strand feels as heat touches it
-
Adjust based on any changes in shine or softness
-
Let every section cool completely before the next step
The right choice keeps synthetic hair looking fresh and full of life wear after wear.
Step-by-Step Guide: How to Curl Synthetic Hair with Heat
Curling adds bounce and movement that turns a basic piece into something special. Clean dry hair gives the cleanest results from the start. Section off small parts so heat reaches every strand evenly. Hold the tool steady for just a few seconds until the fiber warms and takes shape. Release gently and let the curl sit undisturbed until it cools. This short cool down locks the pattern in place better than anything else.
Work from the lower layers upward for easier control. Thicker areas may need a bit more patience while finer strands curl quicker. Mix curl sizes for a natural look that moves with you. The synthetic ponytail extensions in the best-sellers collection often respond beautifully to these custom curls.
Latest News In 2026
New fiber blends hit the market this year and change how synthetic hair styles hold up under heat. These updates focus on softness paired with longer lasting shapes. Soft waves and lived-in textures lead the way for everyday wear. Many people reach for clip-in hair extensions that transform fast and stay put through busy schedules.
Precise temperature controls on newer tools help create consistent looks without guesswork. The best-sellers collection highlights the latest synthetic options that shoppers love right now. Color matching gains attention as users blend heat-styled pieces with their own hair for seamless results.
FAQ
Can synthetic hair handle heat styling tools?
Modern synthetic hair fibers can handle heat styling tools when proper techniques get followed. Always begin with a low temperature setting and test a small hidden section first to see how the fibers react. The hair must stay completely dry before heat application. Many INFINI-FLEX hair pieces respond well to controlled warmth that creates beautiful curls or smooth straight looks.
How do you prepare synthetic hair before using heat?
Start by making sure the synthetic hair is clean and fully dry. Gentle detangling with a wide tooth comb or suitable brush removes knots that could lead to uneven heating. Sectioning the hair into smaller parts allows for more control and better results throughout the styling session. This preparation step helps the fibers accept the new style more evenly when heat gets applied.
Does heat styling lock in a new shape permanently?
Heat styling sets a new curl or straight pattern into synthetic hair quite effectively. The fibers hold onto the shape until another heat session creates a different look. Allowing each section to cool completely after styling helps the new pattern set strongly. This memory feature makes synthetic hair versatile for different styles over time.
What should you watch for during heat styling sessions?
Keep a close eye on how the synthetic hair looks and feels as the tool moves through it. Any sudden changes in texture or extra shine signal that it may be time to lower the temperature. Working in small sections and using steady but brief contact with the tool prevents overexposure to heat. Letting curls or straightened sections cool fully on their own preserves the style and protects the fibers.
Can you switch between curly and straight looks on the same synthetic piece?
Many synthetic hair pieces adapt well when moving between curly and straight styles with heat. The fibers reset to the latest shape applied during the styling process. Consistent gentle techniques and proper cooling help maintain the quality of the hair through multiple style changes. This flexibility supports a wide range of looks with the same piece.

@Sharon Sutera – Hi! We actually do have a link for tutorials and we have a blog here on our website. We’re unsure if you can click on this link but here it is: https://inhhair.com/search?q=how%20to%20tutorials&type=article&view=blog-search
Also, Instead of inserting the comb clip into your scalp, insert it between hair ties so that it bites in horizontally rather than vertically; this provides a much firmer hold while being comfortable. You may also wear the ponytail in a low or mid ponytail if the weight is too heavy.
Message us as support@inhhair.com should you need more assistance.
Are there videos showing how to attach a pony? I find mine very heavy and feel like I might not be putting it on correctly. Thanks.
