What Is Synthetic Hair?

Synthetic hair is manufactured from man-made fibers that are designed to look, feel, and behave like human hair. The most common materials used include:

• Acrylic

• Polyester

• PVC (polyvinyl chloride)

• Kanekalon and Toyokalon (higher-quality fibers)

Each of these fibers undergoes a chemical process to give it texture, color, and durability. The final product is often heat-sealed or chemically treated to hold specific styles like curls or waves.

Unlike human hair, synthetic strands are less porous, which means they don't absorb moisture or styling products. This gives synthetic hair certain advantages—like holding a style longer—but also limits its versatility when it comes to heat styling or chemical treatments.

The Rise of Synthetic Hair in Beauty Culture

The surge in synthetic hair usage can be attributed to various factors:

• Affordability: Synthetic wigs and extensions are significantly less expensive than human hair alternatives.

• Style Retention: Styles such as curls and waves are baked into the hair fibers, making them resistant to humidity and lasting longer.

• Accessibility: Synthetic hair is widely available in beauty stores and online marketplaces.

• Convenience: Synthetic units are low maintenance and ready to wear straight out of the package.

Synthetic hair has found a significant market among those undergoing medical treatments like chemotherapy, individuals with alopecia, and fashion-conscious individuals seeking new looks without altering their natural hair.

Different Types of Synthetic Hair Products

There’s a broad array of synthetic hair products to choose from, each serving different needs:

1. Wigs

These come in full cap, half-cap, or lace front varieties and can be worn for medical reasons, fashion, or convenience.

2. Weaves and Extensions

Synthetic weaves are sewn, glued, or clipped into natural hair to add length or volume.

3. Braiding Hair

Used in protective styles like box braids, crochet twists, or faux locs.

4. Toppers and Hair Pieces

Designed to cover thinning areas or add volume at the crown.

Health Concerns Related to Synthetic Hair

While synthetic hair offers many aesthetic and practical benefits, it’s essential to address potential health implications. Over the years, dermatologists and toxicologists have raised some red flags regarding prolonged or improper use of synthetic hair products.

1. Scalp Irritation and Allergic Reactions

Some synthetic fibers—especially low-grade PVC—can cause allergic reactions, including itching, redness, and inflammation. In particular:

• Kanekalon, a commonly used fiber, is often pre-treated with alkaline coatings that can irritate sensitive skin.

• People with pre-existing scalp conditions like seborrheic dermatitis or psoriasis may experience flare-ups due to friction or chemical exposure.

2. Chemical Exposure

Synthetic fibers are derived from petroleum-based chemicals and are often treated with flame retardants, preservatives, and softeners. Concerns have been raised about the long-term exposure to these chemicals:

• Styrene and acrylonitrile, two compounds used in some synthetic hair, have been identified as possible carcinogens in lab settings.

• A 2016 study analyzed emissions from heated synthetic fibers and found that some released volatile organic compounds (VOCs) that could irritate the respiratory system.

While occasional or short-term use may pose minimal risk, chronic exposure or use under high-heat conditions (e.g., blow dryers or flat irons) could amplify potential harm.

3. Traction Alopecia

Prolonged use of tight hairstyles using synthetic extensions—like box braids or sew-ins—can lead to traction alopecia, a condition characterized by hair loss along the hairline and crown due to excessive tension.

This is particularly common among individuals who wear braids or weaves continuously without giving their scalp time to recover.

4. Respiratory Issues from Heating Synthetic Fibers

Heating synthetic hair can cause it to release fumes. In poorly ventilated areas, these fumes may cause symptoms like:

• Coughing

• Eye irritation

• Headaches

• Dizziness

Although there is limited large-scale research, anecdotal reports and small studies have linked inhalation of these fumes to upper respiratory tract irritation, particularly among salon workers and frequent users.

5. Does Synthetic Hair Cause Cancer?

The evidence directly linking synthetic hair to cancer is limited and inconclusive, but there are some theoretical concerns based on the chemical composition of certain synthetic fibers and how they are used.

Scientific Studies on Synthetic Hair

While the research is still evolving, a few notable studies have examined synthetic hair and its potential health implications:

• A study published in the Journal of Environmental Science and Health (2016) tested emissions from synthetic hair exposed to heat. The results showed the release of VOCs including acetaldehyde and benzene—both of which are considered hazardous when inhaled in large quantities over time.

• A dermatological review in the Journal of Clinical and Aesthetic Dermatology (2020) noted an uptick in scalp dermatitis cases linked to synthetic hair use, especially among individuals with chemical sensitivities.

• A 2015 occupational health study surveyed hairdressers working with synthetic wigs and found a correlation between frequent handling and minor skin issues like rashes and eczema.

These studies don't necessarily suggest a complete avoidance of synthetic hair but rather emphasize the importance of informed usage and proper precautions.

How to Safely Use Synthetic Hair

Given the potential concerns, here are a few tips to enjoy synthetic hair while minimizing health risks:

1. Choose High-Quality Brands

Not all synthetic hair is created equal. Opt for brands that disclose their materials, use hypoallergenic fibers, and avoid unnecessary chemical treatments.

2. Wash Before Use

Especially for braiding hair, a vinegar rinse (1 part apple cider vinegar to 3 parts water) can neutralize alkaline coatings that cause itching.

3. Limit Heat Exposure

Unless your synthetic hair is labeled as “heat-safe,” avoid using curling irons, blow dryers, or flat irons. If using heat, keep temperatures below 350°F.

4. Rotate Styles

Give your scalp and natural hair a break by alternating styles. Avoid wearing synthetic weaves or braids back-to-back for months at a time.

5. Good Ventilation During Styling

If you’re styling with heat, do it in a well-ventilated space to avoid inhaling fumes.

6. Avoid Sleeping in Wigs or Braids Without Protection

Friction from movement can irritate the scalp and tangle the fibers. Use a silk or satin bonnet for protection.

Synthetic vs. Human Hair: Which One Is Better?

This depends entirely on your priorities. Here's a quick comparison:

If you want a budget-friendly, low-maintenance option that looks good straight out of the box, synthetic hair is a solid choice. If you're after versatility and the most natural appearance, human hair might be worth the investment.

Sustainability and Environmental Concerns

Synthetic hair is not biodegradable, which raises concerns about its impact on landfills and marine life. Because it's made from plastic-derived materials, it contributes to microplastic pollution when disposed of improperly.

Some brands are exploring eco-friendly alternatives like plant-based synthetic fibers or offering recycling programs. Still, the industry has a long way to go in addressing its environmental footprint.

To reduce impact:

• Reuse synthetic units when possible.

• Donate old wigs to organizations that refurbish and distribute them.

• Look for brands experimenting with biodegradable fibers.
