Tools You’ll Need

• heat-friendly synthetic wig
• heat protectant spray
• curling iron/wand

Preparing Your Synthetic Wig for Curling

Before you begin curling your synthetic wig, first ensure that your wig is clean and dry. Synthetic wigs can be safely washed but should be washed less frequently than natural hair wigs because synthetic hair does not respond well to moisture, so it is best to avoid getting it wet and only wash it when it starts to look dull or greasy. 

When cleaning, be sure to use a mild, shampoo and conditioner, and avoid rubbing or wringing the hair when you’re washing it. We recommend a Wig Shampoo and a Wig Conditioner. Once the wig is clean and dry, you may begin to curl it.

Using Heat Protectant Spray

Using a heat-protectant spray before curling synthetic hair is a crucial step in protecting the hair from damage. Synthetic hair is more delicate than natural hair and is more susceptible to damage from heated styling tools. A heat-protectant spray helps to create a barrier between the hair and the heat, reducing the risk of damage.

When selecting a heat-protectant spray, look for one that is specifically formulated for synthetic hair. These sprays often contain ingredients that help to protect synthetic fibers from

Applying the heat-protectant spray evenly and generously to each section of the hair as you go is essential. This will ensure that the entire section of hair is protected and will help distribute the product evenly rather than roughly spraying it everywhere before beginning.

Pro tip: heat-protectant sprays can only do so much to protect the hair. It is still key to use the lowest heat setting possible and to keep the curling iron or wand in contact with the hair for the shortest amount of time to minimize heat exposure and damage.

You can also use curling gel or mousse before styling to keep your curls in place and give them a more defined look. Be sure to use a small amount and work it through the hair evenly to avoid weighing it down.

How to Curl Synthetic Hair with Heat

Curling a wig may be intimidating, but it can be made much easier if you use a mannequin or wig stand to rest the wig on while styling. You’ll have more control over how your curls fall and you won’t have to worry about tugging at the hair as you work.

When curling synthetic hair, it’s best to start with small sections. This will allow you to control the heat better and prevent the fibers from becoming too damaged.

1. Take a small section of hair and place it in the curling iron or wand.
2. Hold the hair in place for a few seconds, and then release it.
3. Wrapping the full length of the hair will leave you with bouncy, Hollywood-esque curls while leaving 1” out of the curling iron or rod will give you some boho, beachy waves.
4. Whichever style you prefer, be sure to curl away from your face.
5. Repeat the process until you have curled all the hair.

No-Heat Methods for Curling Synthetic Wigs

There are less heat-intensive options for anyone concerned about causing damage to their synthetic wig. If you have more lead time, using hair rollers or flexi rods to curl synthetic hair is an excellent alternative.

To use this method, roll small sections of hair around the rollers or flexi rods, and secure them in place. Leave the rollers or rods in for a few hours or overnight for tighter curls. 

Styling and Maintaining Curls in Synthetic Hair

When styling your synthetic hair, use a wide-toothed comb or brush to gently detangle the curls. Avoid using a brush or comb with fine teeth, as this can cause the synthetic fibers to break or tangle. Be gentle when brushing or combing and use your fingers to separate the curls and give them a more natural look.

Curling synthetic hair can be intimidating. Still, with the right tools, techniques, and the proper preparation, it is possible to achieve a beautiful, bouncy hairstyle that looks natural and lasts longer.

• Always use a heat-protectant spray
• Avoid using a brush or comb with fine teeth, and use the lowest heat setting possible.
• Alternative methods such as hair rollers or flexi rods can also be used to curl synthetic hair without the use of heat.

Frequently Asked Questions

• Can all synthetic wigs be curled with heat? No, not all synthetic wigs are heat safe. There are two main types: Standard synthetic fiber → Cannot be curled with hot tools. Heat will melt or permanently damage the fibers. Heat-friendly / heat-resistant synthetic fiber → Can be curled, but only at low temperatures. Always check the product description first. If it does not specifically say “heat-friendly” or “heat-resistant,” assume it is not safe for heat styling.
• What temperature should I use to curl synthetic hair? For heat-friendly synthetic wigs, use: 250°F–275°F (120°C–135°C) as a safe starting range. Never exceed 300°F. Start low and test a small section first. Synthetic fibers are more sensitive than human hair and can permanently kink or melt if overheated. Tip: A lower temperature held slightly longer is safer than high heat applied quickly.
• How long do curls last in a synthetic wig? It depends on the fiber type: Standard synthetic: Holds its factory-set style until washed. If you add curls using steam or rollers (not heat tools), they can last until the next wash. Heat-friendly synthetic: Curls can last several days to weeks, depending on: Climate (humidity matters), Friction (hats, collars), Washing frequency. Heat-friendly fibers may gradually relax over time and need restyling.
• Can you use regular hair products on synthetic wigs? It’s not recommended to use regular human-hair products on synthetic wigs. Most traditional shampoos, conditioners, serums, and styling products are formulated with alcohols, heavy oils, and silicones that can dry out synthetic fibers, cause buildup, and lead to tangling over time. Synthetic hair doesn’t produce natural oils like human hair, so it doesn’t need the same type of moisture or product layering. Instead, use products specifically designed for synthetic wigs, such as a lightweight detangling spray, synthetic-safe shampoo, and a conditioning mist made for fiber. Using the right products helps maintain softness, reduce frizz, and extend the life of the wig.

With a bit of practice and patience, you’ll be able to create various curls and waves with your synthetic wig that will look beautiful and last for days. Good luck! If you have any styling questions, reach out to us at hairdo@hairdousa.com.
