Cannabis hair care products have quickly become part of the mainstream beauty market, but their legal and regulatory framework remains complex. For both consumers and manufacturers, understanding how these products are governed helps ensure safety, transparency, and compliance.

At the federal level, the distinction between hemp and marijuana forms the foundation of cannabis product regulation. According to the 2018 Farm Bill, hemp refers to cannabis and its derivatives that contain no more than 0.3% delta-9 THC by dry weight. Products derived from hemp are legal federally, while marijuana-derived ingredients remain classified as controlled substances. This definition allows hemp-derived compounds such as CBD (cannabidiol) to be used in cosmetics, including hair care formulations, provided they meet all relevant standards.

The U.S. Food and Drug Administration (FDA) regulates cosmetics to ensure consumer safety. Under current guidelines, most cannabis-infused hair care products—such as shampoos, conditioners, and serums—are considered cosmetics, meaning they do not require premarket approval. However, once a product makes therapeutic or medical claims, such as “stimulates hair growth” or “treats scalp conditions,” it transitions into the category of a drug. Products making these claims would require formal FDA evaluation and approval before marketing. The FDA has consistently emphasized that companies must avoid false or unsubstantiated claims about CBD’s health benefits.

In addition to the FDA, the Federal Trade Commission (FTC) oversees advertising practices to ensure product claims are truthful and backed by credible evidence. Companies promoting cannabis hair products must be cautious with marketing language, as misleading statements about medical benefits can result in enforcement actions.

Manufacturing and sourcing regulations also shape this market. All hemp used in these products must be cultivated under federally and state-approved hemp programs, adhering to strict testing and reporting standards. Crops testing above the 0.3% THC threshold must be destroyed, ensuring that raw materials remain within legal limits. Responsible manufacturers typically conduct third-party lab testing to confirm purity, potency, and the absence of contaminants.

State-level regulations add another layer of oversight. For example, California’s AB 45 allows hemp-derived ingredients in cosmetics but requires manufacturers to follow testing, labeling, and registration requirements through the California Department of Public Health. Similarly, New York’s Cannabinoid Hemp Program mandates licensing and quality standards for producers and retailers, ensuring that products meet consistent safety and labeling expectations.

Currently, the FDA acknowledges that CBD does not fit neatly into existing food or supplement categories, and discussions are ongoing about establishing a specific regulatory framework. Until clearer guidelines emerge, brands are encouraged to operate within cosmetic regulations—prioritizing product safety, ingredient accuracy, and transparent labeling.

In conclusion, cannabis hair care products are primarily regulated as cosmetics under U.S. law, with oversight from both federal and state agencies. The combination of FDA guidance, FTC truth-in-advertising rules, and state-level testing requirements forms a multi-tiered system designed to protect consumers. In this rapidly growing beauty segment, compliance, quality control, and clear communication remain the hallmarks of trusted brands.
