How to Straighten a Synthetic Wig

There's a common misconception that human hair wigs are "better" than synthetic hair wigs. This is simply not true. Both human hair and synthetic wigs have their own merits, and the best wig for you isn't always the best wig for someone else. If you're looking for a low-maintenance, affordable, and realistic option, a synthetic wig might be the best choice for you. Of course, synthetic hair is not without its faults; namely, heat styling is a no-no. This makes it difficult to restyle or straighten a synthetic wig.

Because synthetic hair is made of a type of plastic, applying heat with a curling iron, hair straightener, or blow dryer will burn, singe, or even melt the hair (unless you have a heat friendly synthetic wig). If you're someone who likes to change their look often, this can be a problem. What do you do if you want to straighten a synthetic wig that's naturally curly?

There are several methods you can use to straighten a synthetic wig, but they all require low-heat styling. This means that you could very easily permanently damage your wig if these techniques are not done very carefully. Before you try these risky methods on your wig, we recommend taking a different approach instead:


Buy a Straight Wig

If you like to wear your hair in different ways, consider buying two wigs: a straight wig, and a wavy or curly wig. It is fairly easy to find wigs with similar styles, lengths, and colors, but different textures. For example, take these two wigs:


There are several upsides to owning two synthetic wigs (instead of trying to straighten a curly synthetic hair wig):

Less Maintenance

Each wig is already styled; all you have to do is decide which wig you want, put it on, and you're good to go.

No Damage

Unlike the low-heat methods used to straighten synthetic hair, there is no chance you will damage the synthetic hair if you decide to own two different wigs.

Longer Lifespan

Like any other article of clothing, wigs become worn out. If you have two different wigs that you alternate, the lifespan of each wig will be extended. While the upfront cost of owning two wigs is higher, the overall price will be similar to owning one wig that will need to be replaced more often.

One to wear, one to wash

If one of your wigs is dirty, there's no need to rush around to wash it and wait for it to dry before you go out; all you have to do is wear your other wig! Wash your wig at your leisure, no waiting required.

Maintains Style

Synthetic wigs have something called "style memory." This means that when the wig is processed, the fibers are shaped with heat into a specific style. Synthetic wigs will always return to this style once they are washed. However, using heat to restyle your wig will change its style memory; instead of returning to its original style after washing, it will return to the new style. Basically, if you mess up while styling your wig, it will be stuck like that unless you use heat again, risking further damage. If you have two wigs instead of styling and restyling one wig, each wigs' style will remain pristine.

If buying two wigs isn't an option but you like to wear your hair  both straight and curly, we recommend buying a straight wig rather than a curly wig. Curling a straight wig without causing damage is much easier and safer than straightening a curly  wig. Find out how here. Conversely, you could try a heat friendly synthetic wig.


If you're still set on straightening your curly wig, there are a couple of methods you can try. Please note, however, that they may damage your wig. Try these tricks at your own discretion.


How to Straighten a Synthetic Wig Method 1: “Bathe” Your Synthetic Wig

How to straighten a synthetic wig with boiling water

  • Step 1: First, put your synthetic wig on a wig stand. Then use a wig comb to remove any knots and tangles.
  • Step 2: Take your wig (while it’s on the stand) into your bathroom and place it in your bathtub.
  • Step 3: Put a big pot of water onto your stove and let the water boil  to a heat of approximately 180F/82C. It is very important to keep the water at this temperature to avoid melting the synthetic fibers.
  • Step 4: Bring the pot of water into the bathroom. Slowly pour it all over your wig.
  • Step 5: Repeat these steps 3 and 4 between 3-5 times.
  • Step 6: Apply some spray on wig conditioner. Gently comb through the wig to remove any tangles.
  • Step 7: Let the wig air dry.


How to Straighten a Synthetic Wig Method 2: Steam Your Synthetic Wig

Another method that you can try is steaming your synthetic wig.

How to Straighten your synthetic wig with steam

  • Step 1: Put your wig on its wig stand. Then use a wig brush to remove any tangles that may be in your wig. While you’re doing this, turn your handheld steamer on so that it can heat up.
  • Step 2: Now you’re ready to start steaming your wig. With a wig brush in one hand and your steamer in the other, work the brush through sections of hair with the steamer following behind. Make sure you don't hold the steamer too close to the wig or hold the steamer in one place too long; this will damage the fibers of the wig.
  • Step 3: Go over each section with the steamer. Repeat at least three times, or until the wig is completely straight.
  • Step 4: Once you’re done, allow the wig to air dry.
  • Step 5: When it is dry, apply a little bit of spray in wig conditioner to it, comb it through and you’re all set!
