Flatlay of Hair Products

You may sometimes wish to straighten a synthetic wig to achieve a sleeker, unique look. It’s important to note that synthetic wigs are not as heat-resistant as human hair wigs, so straightening them requires a slightly different approach. In this step-by-step guide, we’ll walk you through how to straighten a synthetic wig safely and effectively.

Simplest Way to Straighten a Synthetic Wig

Step 1: Gather Your Tools and Materials

  • Gather all the necessary tools and materials:
  • Wig stand or mannequin head
  • Wide-tooth comb for detangling the wig
  • A heat-resistant wig comb or brush suitable for synthetic fibers
  • A hair straightener with adjustable temperature settings
  • Heat protectant spray
  • Clips or hairpins to section the wig for easier straightening

Step 2: Detangle the Wig

Gently detangle it using a wide-tooth comb. Start from the tips and work up to the roots, careful not to pull or stretch the fibers.

Step 3: Set the Straightener to the Right Temperature

Choose the correct temperature setting on your hair straightener. Most synthetic wigs can handle temperatures up to 300°F (150°C). However, check the care instructions.

Step 4: Apply Heat Protectant

Spray a heat protectant designed for synthetic hair evenly throughout the wig to create a barrier between the heat and the wig fibers.

Step 5: Section the Wig

Divide the wig into small, manageable sections using clips or hairpins to make the straightening process more controlled.

Step 6: Straighten the Wig

Working on one section at a time, gently clamp the hair straightener onto the hair, starting from the roots and slowly moving toward the tips. Don’t hold the straightener in one place for too long, as excessive heat can damage the synthetic fibers. Further, use a smooth and steady motion.

Step 7: Repeat as Necessary

Continue straightening each section until you cover the entire wig to your liking. Be patient and take your time to achieve the best results without overexposing the wig to heat.

Step 8: Let the Wig Cool Down

Allow the wig to cool down and set in the straightened style. You can do this on the wig stand or mannequin head.

Step 9: Final Styling

Once the wig has cooled, use a heat-resistant wig comb or brush to style it as desired. You can also add some wig-specific styling products to set the look.

Can and Should You Straighten a Synthetic Wig?

Technically, it’s possible to straighten a synthetic wig, but it requires caution and the right approach. Unlike human hair wigs, synthetic wigs aren’t as heat-resistant. They have synthetic fibers like polyester, acrylic, and modacrylic that can melt or deform when exposed to high temperatures. Fortunately, some synthetic wigs are heat-resistant to a specific temperature (usually around 300°F or 150°C). 

Thus, if your synthetic wig isn’t heat-resistant or you can’t find specific temperature guidelines, it’s best to avoid straightening it because it can get irreparable damage.

On top of that, high-quality synthetic wigs are more likely to withstand heat styling than cheaper alternatives. Cheaper wigs may contain lower-quality fibers that are more prone to damage.

Another consideration before straightening is whether it’ll enhance or compromise the intended style. Some wigs are designed to have specific textures, and altering them may not produce the desired results.

If you can achieve the desired look through alternative methods, such as using styling products or selecting a pre-straightened wig, it may be a safer and more efficient choice.

Tips on How to Make a Synthetic Wig Less Shiny

Although synthetic wigs are affordable and low maintenance, their inherent shininess can sometimes give away the fact that you’re wearing a wig. 

One of the easiest ways to reduce shine in a synthetic wig is to use a dry shampoo or baby powder. Gently sprinkle a small amount of dry shampoo or baby powder onto the wig, focusing on the roots and any shiny areas. Use a brush or your fingers to distribute the powder evenly. It’ll absorb excess shine and make the wig look more natural.

Secondly, a fabric softener rinse can help to dull the shine of a synthetic wig. Mix a solution of one part fabric softener to ten parts water. Submerge the wig in the solution and let it soak for 10 to 15 minutes. Rinse it thoroughly with cold water and gently pat it dry with a towel.

You can also use wig-specific products designed to address the unique needs of synthetic wigs. For instance, consider using a matte finish spray or wig-specific styling products to reduce shine. 

While you should be cautious when using heat on a synthetic wig, you can use a low-heat hair dryer or flat iron (on the lowest setting) to reduce shine. Be careful not to use too much heat, as synthetic fibers can melt. Test on a small, inconspicuous section while continuously brushing or combing it to give it a more natural texture.

Sometimes, how you style your wig can affect how shiny it appears. Hence, create some texture and volume in the wig using gentle backcombing or teasing. It can break up the uniform surface of the wig and reduce its shine.

If your synthetic wig is too shiny and difficult to dull, you may want to consider purchasing a new wig with a different fiber or finish. Some synthetic wigs are designed to have a more matte appearance and may be a better option if shine is a concern.


Yes, you can straighten a synthetic wig using heat-styling tools like a hair straightener or the boiling method. Be cautious not to hold a straightener in one spot for too long to avoid melting the fibers. Remember, synthetic wigs are more delicate than natural hair, so it’s crucial to use low heat.

Popular Questions about Straightening Synthetic Wigs

How can I make my synthetic wig look more natural?

Making a synthetic wig look natural involves various steps. First, ensure the wig fits properly and secure it to your head. Style it to complement your face shape, and use concealer to create a natural hairline. Further, use wig-specific styling products to reduce shine and tame flyaways. You can customize the wig by cutting or thinning it, adding baby hairs, or using root-darkening products.

How do you make a synthetic wig silky again?

You can apply a fabric softener solution. Mix one part fabric softener and ten parts water, submerge the wig in the solution for 10 to 15 minutes, rinse thoroughly with cold water, and gently pat it dry with a towel. The fabric softener helps reduce frizz and restores some of the wig’s silkiness. However, be cautious, as excessive use of fabric softener can cause buildup.

How do you get a synthetic wig to lay flat?

First, fit a wig cap on your head to keep your natural hair in place. Then, use wig clips or combs to anchor the wig. Adjust the wig’s hairline to match your own, and apply adhesive or wig tape for a secure fit. Finally, you can use wig-specific styling products to tame flyaways and set the wig in a flat and natural position.

How do you steam synthetic wigs?

Hang the wig on a wig stand or mannequin head, set a handheld garment steamer to a low heat and steam setting, then gently pass it through the wig sections, focusing on the areas you want to reshape or style. Allow the wig to cool and set in the desired shape, maintaining a safe distance to avoid damaging the synthetic fibers.

How do you straighten a synthetic wig without a straightener?

You can use the boil-straightening method. Boil water, dip the wig inside, and pull it straight to flatten the fibers. Repeat the process until the wig is straight. Be cautious not to overexpose the wig to heat.

How do you restore a cheap synthetic wig?

Start by gently detangling it using a wide-tooth comb or brush. Use fabric softener diluted in water (1:10 ratio) to soak the wig for 10 to 15 minutes, then rinse and pat dry. This method can reduce frizz and help restore some softness. 

How do you make a synthetic wig curly again after straightening?

Use the wet-setting method. Dampen the wig with water and roll small sections of hair around foam or fabric rollers. Secure with pins and allow the wig to air dry, or use a low-heat hair dryer. When the hair is dry, remove the rollers to reveal restored curls. You can also use a curling iron with low heat to redefine the curls but be cautious to avoid further damage to the wig.
