1.1 GBL Article 27, Scope of Practice & Who Must Be Licensed

Key Takeaways

  • General Business Law Article 27 licenses five appearance enhancement disciplines: nail specialty, waxing, natural hair styling, esthetics and cosmetology (GBL § 400).
  • GBL § 400(7) defines cosmetology as the services in subdivisions 4, 5 and 6 — nail specialty, natural hair styling and esthetics — plus services to the hair, head, face, neck or scalp, so one cosmetology licence covers all of them.
  • 19 NYCRR § 160.27 places micropigmentation, massage therapy, nursing and the diagnosis or treatment of disease outside every appearance enhancement licence.
  • Barbering is licensed separately under GBL Article 28; a salon may not permit barbering without a barber shop licence (19 NYCRR § 160.15).
  • An out-of-state or foreign licensee may practise in New York for three months or less per calendar year for training purposes only, and may never serve the public for a fee (GBL § 401(3)).

GBL Article 27, Scope of Practice & Who Must Be Licensed

Exam Focus: Every New York written-exam candidate is expected to know which services the cosmetology licence authorises, which services fall outside it, and which agency enforces the rules. Expect items on the five Article 27 disciplines, the § 400(7) definition of cosmetology, the § 160.27 scope exclusions, and the barbering boundary in § 160.15.


1. The Statutory Framework

In New York, personal beautification services are regulated by Article 27 of the General Business Law (GBL), titled Licensing of Nail Specialty, Natural Hair Styling, Waxing, Esthetics and Cosmetology. The industry term for the whole regulated field is appearance enhancement.

Article 27 is implemented by three regulation parts in Title 19 of the New York Codes, Rules and Regulations (19 NYCRR):

RegulationGoverns
Part 160Licences, business licences, sanitation, disinfection, facilities, postings, inspections, examinations
Part 162The scope of curriculum — the subjects and hours every school must teach for each licence
Part 163Approval of nail specialist trainee courses, including distance-learning rules

Who does what

  • New York State Department of State (DOS) — the executive department that writes the administrative rules, issues licences, investigates complaints, and enforces Article 27.
  • Division of Licensing Services (DLS) — the DOS division that accepts applications, schedules and administers the written and practical examinations, issues licences, and inspects salons. General information line: 518-474-4429.
  • Appearance Enhancement Advisory Committee — a statutory nine-member committee (GBL § 403) that must meet at least three times each year and advises the Secretary of State on all Article 27 matters, consulting the State Education Department on curriculum questions. Its membership is fixed by statute: one nail specialty or waxing practitioner, two natural hair stylists (one knowledgeable in techniques that place tension on the hair roots), one esthetician, two cosmetologists, two educators, and one licensed dermatologist.
  • New York State Education Department (NYSED) — through the Bureau of Proprietary School Supervision and the Office of Career and Technical Education, NYSED licenses the schools and approves the 1,000-hour curricula that must match the DOS content outline.

2. What "Cosmetology" Legally Means

GBL § 400(7) is the single most quotable definition on the exam. It defines the practice of cosmetology as providing the services described in subdivisions 4, 5 and 6 of § 400 — that is, nail specialty, natural hair styling and esthetics — plus:

providing service to the hair, head, face, neck or scalp of a human being, including but not limited to shaving, trimming, and cutting the hair or beard either by hand or mechanical appliances and the application of antiseptics, powders, oils, clays, lotions or applying tonics to the hair, head, or scalp

and, in addition, applying dyes, reactive chemicals, or other preparations to alter the colour or to straighten, curl, or alter the structure of the hair.

The practical consequence is the exam's favourite inference: because § 400(7) swallows subdivisions 4, 5 and 6, a New York cosmetologist does not need a separate nail specialty, natural hair styling, esthetics or waxing licence to perform those services.

GBL § 400 subdivisionPracticeIncluded in cosmetology?
4Nail specialty — cutting, shaping, enhancing nails of the hands or feet, including sculptured and artificial nailsYes
5Natural hair styling — shampooing, arranging, twisting, wrapping, weaving, extending, locking or braiding hair or beardYes
6Esthetics — beautifying the face, neck, arms or upper body with makeup, eyelashes, depilatories, tonics, lotions, waxes, sanding and tweezingYes
10Waxing — hair removal from the face, neck, arms, legs or shoulders by depilatories, waxes or tweezingYes, via subdivision 6
ElectrologyNo — expressly excluded from subdivisions 6 and 10

3. The Hard Boundaries

19 NYCRR § 160.27 lists what appearance enhancement licensure does not authorise. These are the highest-yield "refuse the service" items on the written exam:

  • Micropigmentation and tattooing — outside the licence. If performed in an appearance enhancement business, the owner and operator remain responsible for sanitising, disinfecting and sterilising the implements under other State and local standards.
  • Massage therapy — no appearance enhancement practitioner may practise massage, including manual lymphatic drainage, as defined by Education Law § 7801. A licensee may perform light massage of the surface layers of soft tissue for beautification only. That is why scalp and facial manipulations are legal and deep-tissue work is not.
  • Practice of medicine — no licensee may diagnose or treat disease, including diseases of the skin, hair and nails. An owner may not permit unlicensed medical practice on the premises.
  • Practice of nursing — likewise prohibited.
  • Permanent dyeing of eyelash or eyebrow hair — prohibited, with a single narrow exception: products containing silver nitrate colour additives authorised by the FDA under 21 CFR § 73.2550 may be used to tint lash or brow hair, applied exactly as the manufacturer directs.

Barbering is a different licence

19 NYCRR § 160.15 makes an owner responsible for not permitting barbering at the business location without a barber shop licence under GBL Article 28. Note the asymmetry that catches candidates: the cosmetology operator may shave, trim and cut hair and beard under § 400(7), but the shop still needs the Article 28 licence before barbering is practised there. The same section forbids licensed natural hair stylists from sponsoring or supervising apprentice barbers.

4. Who Must Hold a Licence

  • GBL § 401(1) — no person may practise nail specialty, waxing, natural hair styling, esthetics or cosmetology without a licence, and no person may act as a trainee without a certificate of registration.
  • GBL § 401(2) — no person may own, control or operate an appearance enhancement business without a business licence, whether as sole proprietor, partner, shareholder, officer, independent contractor or otherwise. The independent-contractor language is why an area renter needs a licence of their own.
  • GBL § 401(3) — a practitioner licensed by another state or country may practise in New York for three months or less within any calendar year solely to give or receive training in current styles, techniques or materials. They may not provide services to the public for any fee or other compensation, direct or indirect.
