Professional Practices, Business, and Law
Domain 4: Professional Practices, Business, and Law
This domain tests how a licensed professional works legally, communicates, documents, and runs the business side of services. Questions cover scope of practice, consent, confidentiality, records, regulation, pricing, compensation, and salon operations.
Legal and professional rules
- Scope of practice is defined by state law and the license held; never perform medical diagnosis, prescribe, or treat conditions outside that scope. Refer suspicious lesions, infections, or systemic reactions.
- Informed consent means explaining the service, risks, alternatives, and aftercare, then documenting acceptance. Patch tests and strand tests are part of risk management when required.
- Client records should be factual, dated, legible, and retained per state rules; include products, formulas, test results, and adverse reactions. Confidentiality applies to records and conversations.
- Regulatory roles differ: OSHA addresses workplace safety and bloodborne pathogens; the FDA regulates cosmetics and some devices; the EPA regulates disinfectants; state boards license and enforce cosmetology practice.
Business basics
Know the difference between service revenue and profit. Pricing must cover product cost, time, overhead, and compensation. Booth rental and commission are different models: rent is fixed; commission is a percentage of service revenue. Independent-contractor status depends on control and state/federal tests, not just a signed form. Retail sales, gift cards, and packages create recordkeeping and tax obligations.
Worked example
A stylist grosses $4,000 in service revenue per month. Option A is $1,200 chair rent; Option B is 40% commission. Reasoning: rent leaves $2,800 before product and taxes; commission leaves $2,400 before product and taxes. Rent is better only if the stylist reliably fills the chair and covers overhead; commission may include reception, supplies, and scheduling. The decision should compare total costs, not just the larger number.
Traps
Do not confuse licensing with certification or assume one state's rules apply in another. Do not rely on verbal consent for high-risk services. Do not call a worker an independent contractor without checking control and tax tests. Do not promise medical results.
