What Is Synthetic Hair?

Synthetic Hair


Synthetic hair comprises man-made fibers designed to mimic the appearance and feel of natural human hair. These fibers are engineered to create hair accessories such as wigs, hair extensions, and other embellishments. Synthetic hair is favored by many due to its ability to hold a style longer than natural hair, its affordability, and the sheer variety of styles and colors it comes in. As such, it’s a popular choice for individuals seeking an easy and cost-effective way to experiment with different looks.

Types of Synthetic Hair Fibers

Synthetic hair is made from various artificial fibers, each with distinct characteristics that cater to different needs and preferences. Here are some of the most commonly used types of synthetic hair fibers:

  • Heat-Resistant Fibers – A kind of synthetic hair is made from heat-resistant fibers. These fibers are designed to withstand the heat from styling tools such as hair dryers, curling irons, and hair straightening tools. This makes them an excellent choice for those who frequently style synthetic hair and require more flexibility. Please remember that although these fibers can tolerate heat better than synthetic hair fibers, they should be treated carefully to avoid damage.
  • Kanekalon – Kanekalon is a popular synthetic fiber often used for hair extensions and wigs. Known for its natural look and smooth texture, Kanekalon is loved for its ability to blend seamlessly with natural hair. It is also relatively easy to manage and style. However, it’s important to note that Kanekalon is not highly heat-tolerant, unlike heat-resistant fibers. Therefore, extreme care should be taken when using heating tools on this synthetic hair to avoid melting or irreparable damage.

Key Challenges of Dying Synthetic Hair

Dyeing synthetic hair presents unique challenges compared to dyeing natural hair. The primary reason is the material composition of synthetic hair. Unlike natural hair that absorbs dye, synthetic fibers are nonporous, meaning they cannot absorb or retain the color of traditional hair dyes. Consequently, an attempt to dye synthetic hair with regular hair dye can result in an uneven color or the dye simply washing out.

Color Limitations

The structure of synthetic fibers greatly influences their ability to hold and retain color. Unlike natural hair with a porous surface that absorbs and retains the dye, synthetic fibers have a closed, nonporous surface. This lack of porosity makes it difficult for the dye to penetrate and adhere to the fiber.

Consequently, when the dye is applied to synthetic hair, it tends to sit on the surface rather than sink in, leading to less effective color retention. This is why traditional hair dyes, designed to penetrate the hair shaft, are typically ineffective for synthetic hair use. Instead, dyeing synthetic hair often requires specialized products or methods to ensure that the color can adhere to the surface of the fibers and remain vibrant over time.

Challenges of Achieving Vibrant and Lasting Colors on Synthetic Hair

Achieving vibrant and lasting color on synthetic hair can be an uphill battle due to several challenges. Unlike natural hair, which possesses a porous structure that allows for the absorption and retention of dye, synthetic hair is nonporous, making it resistant to traditional dyeing methods. As a result, the dye tends to sit on the surface of synthetic hair, leading to less vibrant colors and poor color retention.

Moreover, achieving a drastic color transformation can be tough due to the dye resistance inherent in synthetic hair fibers. Synthetic fibers are often infused with strong, fade-resistant colors during production, making it challenging to overwrite these colors with new ones. For example, trying to turn a dark synthetic wig blonde may not yield the desired outcomes, as the original color may continuously shine through, dampening the vibrancy of the blonde hue.

Additionally, the shininess of synthetic hair can also pose a challenge. While a certain level of shine lends a healthy appearance to hair, synthetic hair can often appear excessively shiny, especially after dyeing, resulting in an unappealing, artificial look. Balancing the need for vibrancy while keeping shine at an acceptable level is a considerable challenge when dyeing synthetic hair.

Lastly, synthetic hair cannot self-repair, unlike natural hair, which can recover from damage over time through natural oil production and protein replenishment. Any damage caused by the dyeing process, such as dryness, brittleness, or loss of texture, will likely be permanent. This can affect not only the appearance of the hair but also its longevity, making achieving vibrant and lasting color an arduous task.

Heat Sensitivity

One crucial characteristic of synthetic hair to note during the dyeing process is its sensitivity to heat. While engineered to mimic real hair, synthetic fibers do not possess the same resistive qualities when exposed to high temperatures. This can make dyeing synthetic hair particularly tricky, as the application of heat can cause the fibers to become irreversibly damaged, leading to unwanted changes in texture and appearance. Exposure to heat is also one of the causes of hair loss.

The heat sensitivity of synthetic fibers is such that they may melt or warp when exposed to high temperatures, ruining the style or the entire piece of synthetic hair. Therefore, it’s crucial to use low heat when dyeing synthetic hair. This includes using warm water instead of hot for the dyeing process and allowing the synthetic hair to air dry rather than using high-heat blow dryers. Avoiding hot styling tools such as curling and flat irons can also prevent damage.

Remember, while some synthetic fibers are marketed as heat-resistant, they are not immune to the damaging effects of high heat, especially during the dyeing process. Even heat-resistant synthetic hair should be treated cautiously to ensure longevity and vibrant color. You can successfully dye your synthetic hair by managing heat exposure and avoiding unnecessary damage.

Specialized Dyes

Due to the unique nature of synthetic hair, specialized dyes have been developed specifically designed to adhere to synthetic fibers and provide better color results. These dyes differ from traditional hair dyes in their formulation and application methods. They work by depositing color onto the synthetic fibers rather than penetrating them, which helps to achieve more vibrant, long-lasting results.

Examples of such dyes include fabric dyes and ink-based products, which are renowned for their ability to color synthetic hair successfully. However, it’s worth noting that even with these specialized dyes, dyeing synthetic hair can still be challenging, requiring patience and attention to detail. As always, doing a strand test before fully committing to a new color is recommended to ensure it gives the desired result.

Steps to Dye Your Synthetic Hair

Here’s a step-by-step guide on how to dye synthetic hair effectively.

Pre-Dyeing Preparation

Preparing synthetic hair for drying requires special attention and care not to damage the fibers. Here are some steps you should take before beginning the dyeing process:

  • Detangle Synthetic Hair – The first step in preparing to dye your synthetic hair is to detangle it carefully. Start from the ends and work up to the roots to prevent damaging the fibers. Use a wide-tooth comb or a special wig brush to remove any knots or tangles gently. Avoid pulling or tugging at the hair, as this can cause unnecessary damage to the synthetic fibers.
  • Washing Synthetic Hair – Once the synthetic hair is detangled, it’s time to wash it. Use lukewarm water and a gentle shampoo, preferably a product specifically designed for synthetic hair. Ensure to distribute the shampoo evenly throughout the hair and rinse thoroughly. It’s crucial to eliminate debris, oils, or previous product build-up, as this can interfere with the dyeing process.

Avoid twisting, wringing, or rubbing synthetic hair during washing. After rinsing, gently squeeze out excess water or pat the hair dry with a towel. Do not blow dry; leave it to air dry completely before proceeding with the dyeing process. This preparation will ensure your synthetic hair is perfectly primed and ready to absorb the dye.

The actual dyeing process of synthetic hair requires patience and attentiveness to ensure even and adequate coverage:

  • Choose the Right Dye: Regular hair dye will not work on synthetic hair. Instead, you’ll need to use a product specifically designed for synthetic fibers, such as a fabric dye or an ink-based product. Ensure to read and follow all the instructions on the packaging to avoid mishaps.
  • Perform a Strand Test: Before you proceed to dye the entire synthetic hair, it’s advisable to perform a strand test. This will allow you to see how the dye interacts with the synthetic hair and if it achieves the desired color. To do a strand test, simply apply the dye to a small, inconspicuous section of hair and let it sit for the recommended time before rinsing. If you’re satisfied with the results, you can proceed with the rest of the hair.
  • Apply the Dye: For the dye application, wearing gloves is recommended to protect your hands. Start by dipping the synthetic hair into the dye solution, thoroughly covering every strand. Use a comb to evenly distribute the dye throughout the hair, from roots to ends, to ensure complete coverage. Include all sections, as this could result in patchy or uneven color.
  • Let the Dye Set: Once applied correctly, let it sit for the recommended period on the dye package. This allows the dye to adhere fully to the synthetic fibers and achieve a vibrant, lasting color. Be sure to leave the dye in briefly, as this can lead to unnecessary damage and may negatively affect the color results.
  • Rinse the Synthetic Hair: After the dye has been set, rinse the synthetic hair under lukewarm water until the water runs clear. This will remove any excess dye from the hair. Remember, synthetic hair is sensitive to heat, so avoid using hot water as it could damage the fibers.

Following these steps, you can apply dye to your synthetic hair, ensuring even coverage and vibrant, lasting color.

Heat Application

Heat plays an instrumental role in the dyeing process of synthetic hair, particularly in setting the color. After you’ve applied the dye and rinsed out the excess, using heat can aid in locking in the color, making the results more vibrant and long-lasting.

However, the key is to use a low-heat setting or steam to avoid causing damage to the synthetic fibers. Synthetic fibers can be susceptible to high temperatures and melt or become irreversibly damaged when exposed to excessive heat. Therefore, it’s crucial to control heat exposure when dyeing synthetic hair.

You can use a low-heat setting on a hairdryer to gradually dry the synthetic hair after dyeing. Using a diffuser attachment on your hairdryer can also help distribute the heat more evenly and prevent hotspots that could damage the synthetic hair.

Alternatively, you can use a steamer designed for synthetic wigs to set the color. The steam helps open the synthetic fibers to receive the dye, and as it cools down, the fibers contract, trapping the dye inside. This method can benefit synthetic hair types that are more resistant to dye.

Is It Good to Dye Synthetic Hair?

Here are the pros and cons of dyeing synthetic hair.


Dyeing synthetic hair presents several notable advantages. Firstly, it allows for personalizing hair color and style according to one’s preferences, seamlessly blending with your style or mood. This offers a fun and creative avenue for self-expression, enabling you to experiment with different colors and trends that may otherwise be risky or damaging to natural hair.

Secondly, dyeing synthetic hair allows for change without commitment. Unlike dyeing natural hair, which requires continual maintenance and touch-ups, synthetic hair can be swapped out easily, allowing for frequent and drastic changes in appearance. This flexibility can appeal to individuals who enjoy regularly changing their look or wish to test a new color before committing to it on their natural hair.

Lastly, dyeing synthetic hair can help to update or refresh the appearance of older synthetic hair pieces. Over time, the color of synthetic hair can fade or change due to exposure to sunlight, washing, or general wear and tear. Dyeing these hair pieces can restore their vibrancy, extending their life and ensuring they remain a valuable part of your style repertoire.


Despite the benefits, dyeing synthetic hair has limitations and risks. One of the main downsides is the color limitations of dyeing synthetic hair.
