3 Easy Methods To Help You Straighten Synthetic Hair At Home

On different occasions and reasons, we have to wear synthetic hair or more commonly known as wigs.

Almost any wig can be straightened, but synthetic-fiber wigs require more care. Since the fibers are made of plastic, they are very sensitive to high temperatures and cannot be straightened using a hair straightener.

One exception is wigs made from heat-resistant fibers. This article will show you 3 simple ways to straighten your synthetic fiber wigs.


Can I straighten a synthetic wig?

Unless you have a wig that is very heat resistant, it is okay to straighten them.

On the contrary, straightening synthetic wigs with a hair straightener at high temperatures will cause irreversible damage to the hair fibers or even destroy them. And then you can’t reuse them.

Unlike natural hair or wigs made with human hair, synthetic wigs inherently cannot withstand the excessive heat from straighteners.

How hot can you straighten synthetic hair?

After your synthetic hair has been straightened and sprayed with anti-hot spray, place it on the wig head or holder to make the process easier.

Now it’s time to plug in the straightener and set the heat to about 250-300 degrees. Because, even Japanese synthetic hair, which is silky smooth and looks like real hair, can only withstand heat up to 400 degrees.

And after that, you can go through the normal straightening process.

  • Divide into parts and straighten from base to tip.
  • After the hair has cooled, comb from the tips to the roots.

Can you flat iron synthetic hair?

For natural hair, it’s pretty simple to iron it or even any flat iron can do this.

However, confusion will start to arise when you need to flatten your wig or synthetic hair. With very few exceptions, you can use an iron to flatten synthetic hair.

Because, as we all know, synthetic hair made of plastic and hot flat iron can easily damage these resins. That suggests we need to take more care while being flat synthetic hair.

However, when using quality irons as well as some high heat resistant synthetic hair types, the damage will not be an issue at all.

How to straighten synthetic hair?

At this point, you have certainly gained yourself a precise understanding of the effects of straightening on your synthetic hair.

In this section, we’ll go over to teach you 3 methods to straighten a wig.

Method 1: Use hot water

Things you’ll need:

  • A wide-tooth comb
  • Large pots
  • Hairdryer


  1. Step 1: Use a wide-tooth comb to remove tangled hair.
  2. Step 2: Place a pot of water on the stove and boil to 356°F (160°C to 180°C). Try to use a large pot depending on the length of the hair to get enough water to pour over the wig.
  3. Step 3: Dip the entire wig on the pot for 10-15 seconds, then pull the wig out. Place the top of the wig back onto its stand.
  4. Step 4: If you detect some tangles, you can gently wipe them out with your fingers. Because using a comb will damage the wig.
  5. Step 5: Use a hairdryer (the “cool” setting) to dry your wig.
  6. Step 6: Repeat the process if needed or the hair is not as straight as desired.

Method 2: Use steam for gently straightening

Things you’ll need:

  • Wig stand
  • A wide-toothed comb/ a wire wig brush


  1. Step 1: Place the wig stand in the bathroom and close all the doors to trap as much steam as possible.
  2. Step 2: Shower in hot water for some time until the room has steam.
  3. Step 3: Comb your hair gently with a wide-toothed comb or a wire wig brush. (brush from the front ends)
  4. Step 4: Take the wig out of the room when the steam starts to build up and then transfer it to a cool, dry place.

Method 3: Using a hairdryer for extreme straightening

Things you’ll need:

  • Hairdryer
  • A wide-toothed comb/a wire wig brush
  • Hair clip


  1. Step 1: Gather all the hair (except the bottom part) into a loose bun at the top and fix the bun with a hair clip.
  2. Step 2: Spray the bottom layer with water to keep the fibers from overheating.
  3. Step 3: Gather a part of hair from 1-2” (2.54 – 5.08 cm) wide.
  4. Step 4: Use a wide-toothed comb or a wire wig brush to smooth the synthetic hairs down. Make sure no areas are completely tangle-free.
  5. Step 5: Set the hairdryer to a warm heat setting. Then move the comb/brush and hairdryer downwards at the same time. You can repeat this process 2 or 3 times.

For a synthetic wig, styling or heat straightening is not advisable as this will affect the longevity of the synthetic hair.

Better yet, you should consider buying two wigs: One straight wig and One wavy or curly wig. However, if you still need to straighten them then try the little damaging tricks we’ve provided at your own discretion. Good luck!
