This guide covers the full regulatory picture for personal care businesses, organized by the system doing the regulating rather than by the service being provided. It begins with occupational licensing — how licenses are obtained, what scope of practice means, and how board discipline works — and covers the antitrust supervision question that constrains boards controlled by market participants. It then addresses the establishment license and facility requirements, the booth rental arrangement and the classification tests that determine whether it holds, and the wage, tip, and tax obligations that follow from the answer. It covers sanitation standards and their federal pesticide-registration underpinning, the cosmetics framework governing products, OSHA obligations including bloodborne pathogen control, and the body art rules that layer on top. It closes with liability, insurance structure, public accommodation obligations, and the industry-specific labor enforcement that has reshaped parts of the field.
