The Toxic Truth: Why Your Synthetic Braids Might Be Harming Your Health

Our much-awaited conversation on synthetic hair is finally here. We love these braids—the vibrant colors, the convenient styles, the way they allow us to rock a protective look for weeks or months. But behind the promise of low cost and convenience lies a shocking truth that scientists are only now bringing to light: the very hair we call “protective” is exposing millions of women and young girls to hazardous, unregulated chemicals.

This isn’t about shaming anyone; it’s about awareness and demanding better for our health and our communities. Let’s look at the lab-verified findings that no one ever bothered to tell us.

1. The Chemical Cocktail: What’s in Your Braids?

If you pick up a pack of synthetic braiding hair, you’ll notice one thing immediately: there are almost no ingredients listed. While manufacturers hide the recipe, scientific studies have revealed a cocktail of concerning substances.

A 2025 investigation by Consumer Reports tested 10 of the most popular synthetic braiding brands used by Black women across the US and found they contained non-carcinogens (substances linked to cancer) and heavy metals. These included:

Benzene
Styrene
Toluene
Lead

All of these are recognized by the US Environmental Protection Agency (EPA) and the World Health Organization (WHO) as potential causes of cancer or neurological damage.

Furthermore, a 2024 review from Harvard T.H. Chan School of Public Health confirmed that hair care products marketed to Black women frequently contain endocrine-disrupting substances linked to reproductive issues and cancer. The Environmental Working Group also revealed that hair care products marketed to Black women are more than twice as likely to contain hazardous ingredients compared to mainstream products.

In short, the industry has been selling products laced with chemicals that would be tightly restricted in markets like the European Union.

2. The Danger of Heat: The Toxic Fume Release

Most synthetic braiding hair—including popular low-cost polymer fibers like Kanekalon and Toyokalon—are forms of Polyvinyl Chloride (PVC), essentially plastic. The danger escalates when this plastic is exposed to heat, a standard practice in styling.

When braids are heat-sealed (melted with a lighter) or dipped in boiling water, this heat exposure releases Volatile Organic Compounds (VOCs) directly into the air.

A 2024 study in the Journal of Environmental Health Perspectives found that heat-sealing synthetic hair releases VOCs, including: Benzene, Styrene, Chloroethane, and Acetonitrile, all of which are known or suspected human carcinogens.
When PVC is burned, it releases dioxins and hydrogen chloride, both listed by the United Nations Environmental Program (UNEP) as highly toxic substances. Dioxins are persistent organic pollutants (POPs), meaning they accumulate in the body and environment and do not disappear.

The Invisible Threat in the Salon: Black women and hair stylists are breathing this air in small, often unventilated salons day after day. A 2019 investigation by the National Institute for Occupational Safety and Health (NIOSH) found that immediately after heat treatment, the air was full of strong chemical fumes, including Formaldehyde, a known carcinogen. While the concentration may be low for one client, the cumulative exposure for stylists who handle this hair all day is significant.

Every time a lighter is flicked to seal the ends, an invisible cloud of plastic smoke containing these toxins settles on the face, scalp, and nose.

3. The Scalp: A Porous Absorber

The scalp is highly porous and absorbs whatever is placed on it. This means that dyes, preservatives, and residues from synthetic fibers don’t just sit on the hair; they can enter the skin barrier.

Allergic Reactions: Dermatologists confirm that many synthetic products contain Acrylonitrile and Vinyl Chloride residues, which are skin irritants. The common and intense itching, redness, and burning some experience after braiding is often a chemical reaction, not just tension.
Chemical Coatings: Synthetic fibers are treated with various coatings—including flame retardants and quaternary ammonium compounds (antimicrobial agents)—to ensure they are durable and look shiny during shipping. These chemicals are the culprits behind allergic contact dermatitis, swelling, flaking, and in some cases, hair loss around the edges.
A 2023 paper in the International Journal of Trichology documented that over 60% of Black women who reported post-braiding scalp irritation were reacting to these chemical coatings.

4. The African Blind Spot: Unregulated Toxicity

While some testing is starting in the US, regulation in African markets is almost entirely absent, making the exposure risk far higher.

No Safety Testing: African regulators, such as the Kenya Bureau of Standards (KEBS) and South African bodies, rarely test imported synthetic hair for toxic chemicals. This is because, in countries like Kenya, synthetic hair is often classified as a textile import, not a cosmetic or chemical product, bypassing rigorous toxicity screening.
Violation of Law: The African Institute for Environmental Health reported in 2024 that over 70% of synthetic hair products sold in East Africa are imported without ingredient labels or safety data sheets, violating the African Union model law on chemicals management.
Low-Quality Imports: Much of the low-cost synthetic hair shipped to African markets is made from recycled or downgraded PVC, often mixed with cheap pigments containing lead and cadmium. These two metals are strictly banned in cosmetic pigments under European Union safety laws, but they enter African ports unchecked.

The result is that low-grade, unregulated products—the same product lines that would fail European safety checks—are sold freely across Africa, funding a $6 billion USD annual industry (according to the African Development Bank, 2023) where the profits leave the continent, and the risks stay with the consumers.

5. The Long-Term Health Risk: Endocrine Disruption

The most serious concern is the cumulative exposure over time. Black women often maintain these styles frequently and for extended periods (sometimes two months or longer). Chronic exposure to these chemicals creates long-term health risks.

Hormone Interference: Many substances in synthetic hair (styrene, formaldehyde byproducts, heavy metals) are classified as endocrine disruptors. They interfere with the body’s hormones (estrogen, progesterone, thyroid hormones) even at low doses.
Reproductive Issues: Harvard researchers noted that Black women show higher levels of certain endocrine-disrupting compounds in their blood and urine compared to other groups. A 2023 study in the Journal of the National Cancer Institute found that long-term exposure to these hormone-disrupting chemicals may partially explain why Black women in the US have higher rates of uterine fibroids and certain reproductive cancers.
Carcinogen Accumulation: Dioxins, released when hair burns, build up in body fat and breast tissue and can stay in the system for decades. The WHO states there is no safe level of dioxin exposure.

This parallels the painful history of chemical relaxers, which were marketed as safe until decades later, studies confirmed a link to higher risks of uterine cancer in frequent users, particularly Black women.

What We Can Do: Demanding Better

This is not a policy failure. It is a justice conversation. Our governments and corporations must prioritize the safety of Black consumers.

Demand Ventilation: Always ensure the salon is well-ventilated (windows open, fans on). If heat sealing is necessary, ask the stylist to avoid doing it directly near your face—or ideally, ask them not to do it at all, as the fumes still pollute the air.
Rinse Your Hair: Before installation, wash new synthetic hair. Experts, citing a 2023 study in the International Journal of Trichology, suggest soaking new synthetic hair in diluted apple cider vinegar to reduce chemical coatings (flame retardants and antimicrobials) that cause scalp irritation.
Limit Wear Time: Experts at Harvard recommend limiting long-term contact with treated synthetic fibers to no more than six weeks at a time to allow the scalp time to breathe and reduce chronic chemical contact.
Demand Transparency: Do not buy hair that lacks an ingredient list, country of origin, or compliance labels. This is a red flag. Start asking your local beauty supply stores to demand safety data sheets from their suppliers.
Support Alternatives: Seek out and support African innovators creating safe, toxin-free alternatives. Companies like Rebundle, which use plant-based fibers (like banana stem and kenaf), prove that beauty and safety do not have to be mutually exclusive.
Pressure Regulators: We must use our collective power as a $6 billion market to demand accountability from government bodies like KEBS. Regulators must be forced to test imported hair for toxins and enforce the existing laws on chemical disclosure.

Our crown should never come with cancer warnings. If we call these styles protective, they must protect our health, our dignity, and our future. Know the truth, demand better, and protect your power.
