For years, many people assumed that human hair was the cleaner, safer choice when it came to braiding. A major new study has turned that assumption on its head and the findings carry real consequences, particularly for Black women who rely on braiding hair products regularly.
Consumer Reports tested 30 popular braiding hair products spanning human, plant-based, and synthetic categories. The results were difficult to ignore: 29 out of 30 products contained lead, and human hair came back with the highest levels of any category tested.
What the Consumer Reports study found
The study, conducted last year, cast a wide net across the braiding hair market. Researchers examined products at varying price points and from widely available brands, and the presence of heavy metals turned up with remarkable consistency.
Among the specific products flagged, 1. Ywigs Water Wave Bulk recorded the highest lead levels of any item tested, significantly exceeding the thresholds Consumer Reports considers acceptable. 2. Yummy Extensions and 3. Sensationnel also came back with concerning readings. The breadth of contamination across brands and hair types suggests this is an industry-wide issue rather than an isolated problem with a handful of products.
To assess the real-world risk to consumers, researchers used a hand-to-mouth exposure model a method that accounts for how people may inadvertently ingest small amounts of material through ordinary daily activities like touching their hair and then eating or drinking without washing their hands first. The model reflects how exposure to heavy metals can accumulate gradually, building toward health consequences that may not be immediately visible.
Why human hair tested worse than synthetic
The finding that human hair carried more lead than synthetic alternatives surprised many observers, given the longstanding perception that natural materials are inherently safer. Researchers pointed to two primary explanations.
First, the individuals who grow and donate or sell the hair may themselves live or work in environments with elevated lead exposure, which the body stores in hair over time. Second, the processing that human hair undergoes before it reaches consumers including dyeing, chemical straightening, and other treatments can introduce additional contaminants into the product.
Together, these factors create a situation where human hair, despite its natural origin, may arrive at the consumer carrying a heavier toxic load than lab-produced synthetic fiber.
Where plant based options stand
Plant-based braiding hair has gained a following among consumers looking for alternatives to both human and synthetic products. The Consumer Reports findings suggest these options are not entirely in the clear either, though they generally fared better than human hair.
- Rebundle, a brand that uses banana plant fibers and markets itself as a non-toxic option, recorded the tenth-lowest lead levels among all products tested a relative bright spot, though not a clean bill of health. The company has said it is actively investigating potential sources of contamination in its supply chain, a response that consumer advocates have described as a step in the right direction.
The one brand that came back clean
Amid results that were largely discouraging, one brand stood apart. 1. Dosso Beauty was the only product tested that contained no detectable levels of heavy metals, including lead, mercury, and cadmium. Its Kanekalon Fiber line has undergone independent testing specifically designed to screen for the kinds of substances flagged in the Consumer Reports review.
The endorsement from inside the research team itself was notable the study’s lead researcher on product safety said he recommended the brand to his own daughter for regular use, a personal vote of confidence that carries weight beyond the formal findings.
What consumers can do now
The study lands at a moment when awareness of environmental toxins in personal care products is growing, but regulatory oversight of the braiding hair category remains limited. There are currently no federal requirements that braiding hair products be tested for heavy metal content before reaching store shelves.
For consumers, particularly Black women who wear braided styles frequently and for extended periods, that gap in oversight places the burden of research on the individual. Researchers are encouraging people to seek out brands that voluntarily publish third-party safety testing results and to push back against manufacturers that do not prioritize transparency.
The Consumer Reports findings make clear that the braiding hair industry has significant ground to cover and that the stakes for getting it right are not cosmetic. They are a matter of public health.
