FDA hair regulations define how the U.S. Food and Drug Administration oversees ingredients, labeling, and safety for hair care and professional hair treatments. These rules shape product claims, ingredient approvals, and recall processes for shampoos, conditioners, dyes, relaxers, and scalp treatments.
Below is a structured overview of core FDA topics relevant to consumers and industry professionals, followed by deeper sections on policy, devices, labeling, and questions people commonly search.
| Topic | Key Detail | Relevance | Status |
|---|---|---|---|
| Cosmetics vs Drugs | Shampoo and conditioner are generally cosmetics; dandruff or hair loss claims can move a product to drug classification | Determines product oversight | Current |
| Color Additives | Hair dyes require preapproval for certain ingredients and batch certification | Safety and legality | Active enforcement |
| Labeling Rules | Ing lists, warnings, and claim substantiation must follow 21 CFR 740 and 770 | Consumer clarity and compliance | Current |
| Professional Devices | Flat irons, curlers, and UV lamps are regulated as devices when intended to alter structure or appearance | Market access and safety | Varied by risk class |
Federal Policy on Hair Cosmetics
Under the Federal Food, Drug, and Cosmetic Act, the FDA treats most shampoos and styling creams as cosmetics, which do not require premarket approval. However, products that make claims to treat, prevent, or diagnose hair or scalp conditions are considered drugs and must comply with drug registration, labeling, and good manufacturing practices. The FDA also provides voluntary cosmetic registration programs and guidance letters to clarify expectations for firms.
Hair Dye and Color Additive Rules
Hair dyes often contain color additives that must be approved for specific uses. Some dyes are subject to batch certification, where manufacturers test each lot for safety before distribution. The FDA maintains lists of approved colorants in 21 CFR, and adulterated or misbranded dyes can trigger warning letters or import holds for international suppliers.
Labeling and Claim Compliance
Labels must list ingredients in descending order, include the manufacturer’s name and address, and avoid misleading statements. Health claims such as regrowth or disease treatment require drug approval, while structure/function claims for scalp health must be truthful and not misleading. The FDA evaluates labeling during inspections and complaint-driven investigations.
Professional Hair Care Devices
Scope of Regulation
Flat irons, curling wands, and handheld dryers are typically considered devices when they create heat or light effects that change hair structure. If marketed with medical claims, they may also face drug classification. Manufacturers may need to register with the FDA and report adverse events if injuries are significant.
Safety Standards and Certifications
While the FDA does not pre-approve devices, importers and domestic firms must verify compliance with recognized standards such as IEC 60335 series. Many salons rely on third-party certifications like UL or CE to streamline distribution, even when those marks are not FDA-specific.

FAQ
Reader questions
Are FDA-approved hair growth products available to consumers?
Yes, two topical drugs, minoxidil and finasteride, are FDA-approved for certain types of hair loss and are available by prescription or over the counter.
What should I do if a hair dye causes a severe reaction?
Stop using the product immediately, seek medical care, and report the incident to the FDA through its Safety Reporting Portal or by phone.
Can a shampoo claim to thicken hair without being a drug?
Shampoos may use temporary thickening or volumizing language, but claims to restore or rebuild hair density generally require drug approval and evidence. The FDA screens imports for unapproved drugs, misbranded labels, or banned ingredients; violators may face detention, refusal of entry, or recalls at the border.
