How to Start a Hair Extensions Business in New Hampshire: Licenses, Costs & Requirements

Who regulates hair extensions in New Hampshire

One office runs New Hampshire beauty licensing: the Office of Professional Licensure and Certification, OPLC, advised by the Board of Barbering, Cosmetology, and Esthetics, under chapter 313-A of the Revised Statutes Annotated. The chapter covers barbers, master barbers, cosmetologists, manicurists, estheticians, instructors, apprentices, shops and schools; OPLC issues the licenses and sets the fees by rule, and the fee schedule lives at Plc 1002.07 rather than in the statute. Extension work is regulated inside that chapter, but not under its own heading: no section mentions hair extensions as a licensed service, and the only place the chapter uses the words at all is the natural hair braiding exemption at RSA 313-A:25 XIII. The rest of your setup spreads across the Secretary of State, the Department of Revenue Administration, New Hampshire Employment Security and the Department of Labor.

The stakes are printed in the chapter itself. RSA 313-A:9 makes practicing cosmetology for pay without a license a class A misdemeanor for a natural person and a felony for any other person, so the studio entity carries the heavier exposure. Operating a shop not at all times under a licensee's direct supervision and management is a misdemeanor, and so is employing or allowing an unlicensed person to practice.

New Hampshire hair extensions business requirements at a glance

The license question: the cosmetologist license and its limits

Start with what the statute does not say. The cosmetology definition at RSA 313-A:1 VI covers arranging, dressing, curling, waving, cleansing, cutting, bleaching, coloring, or similarly treating the hair of any person, plus the other work customarily performed by a cosmetologist. It never names weaving, extending or attaching hair, and neither do the barbering definition at RSA 313-A:1 II or the master barber definition at RSA 313-A:1 II-a. Weaving and extending appear exactly once in the chapter, inside that exemption, and the licensed side of this trade is defined by what the exemption leaves out. The cosmetologist license is the authorizing license for everything past the exemption line, because it is the only New Hampshire license whose scope reaches cutting, coloring and chemical work on hair.

The cosmetologist route has two doors under RSA 313-A:11. The school door is 1,200 hours in a school of cosmetology approved by the board. Read that figure carefully against older material: the statute required 1,500 hours until the 2025 amendment, effective August 9, 2025, cut it to 1,200, and directories and school catalogs still printing 1,500 describe the repealed requirement. The apprenticeship door is 3,000 hours over at least 18 months under a licensed cosmetologist with at least two years of practice in New Hampshire; it did not shrink with the school hours, so it now runs two and a half times the classroom route. Either route also requires good professional character, a high school education or its equivalent, and passing the board's examination, held at least once every six months under RSA 313-A:15. The license costs $50 for two years under Plc 1002.07 and is displayed near the work station under RSA 313-A:17.

The narrower licenses stop short of installing, and their names mislead people. There is no hairstylist license in New Hampshire at all: the chapter licenses barbers, master barbers, cosmetologists, manicurists, estheticians and instructors, and nothing narrower touches hair work. The barber license at 800 hours covers the barbering definition, and the master barber license at 1,500 hours adds dyeing and styling, waving, curling, straightening or bleaching by mechanical or chemical means; neither definition names weaving or attaching hair, so neither is an installs credential. The esthetician and manicurist licenses authorize no hair work. A studio that wants one person to install bonded rows, blend the cut and match the color needs a cosmetologist, full stop.

There is also no specialty license for weaving or extensions, in either direction. Nothing in RSA 313-A creates one, and the fee table at Plc 1002.07 confirms the absence from the other side: its categories are the five personal licenses, tanning registration, apprentice certification, the instructor license, the booth rental line the 2023 repeal left behind, and shop and school licenses. Anyone selling a New Hampshire extensions certification as a state credential is selling a document the statute does not create; private training certificates can be worth taking for skill, but they carry no licensing weight.

The braiding boundary: where unlicensed installs end

New Hampshire deregulated natural hair braiding in 2017, and it reaches extensions directly, because the definition covers this trade's core methods. RSA 313-A:25 XIII exempts persons engaged in the practice of natural hair braiding from the chapter entirely, and defines the practice as the service of twisting, wrapping, weaving, extending, locking, or braiding hair by hand or with mechanical devices, a device list that includes blunt-tipped needles and thread. The practice includes the use of natural or synthetic hair extensions, fibers, decorative beads and other hair accessories; minor trimming of natural hair or hair extensions incidental to the service; the making of wigs; and topical agents. A sew-in weave is weaving and extending with a blunt-tipped needle and thread, both named in the definition, so sew-ins and braid-attached installs sit inside the exemption, and no license, registration, course or fee attaches anywhere in the chapter or in Plc 1002.07. Our New Hampshire braiding guide covers that exempt trade in full.

The boundary is drawn in the same paragraph, and it is chemical. Natural hair braiding does not include the application of dyes, reactive chemicals, or other preparations to alter the color of the hair or to straighten, curl, or alter the structure of the hair, and it does not include the use of chemical hair joining agents such as synthetic tape, keratin bonds, or fusion bonds. So the exemption ends at the joining agents it names, a tape-in, keratin bond or fusion install is licensed cosmetology work even when braids sit underneath it, and at chemistry and cutting generally: color, bleach, relaxers, texture altering preparations and cutting beyond minor incidental trimming are all licensed work. One honest gap belongs on the page: the chapter never names microlinks or beaded rows. The definition tests a method by its technique and chemistry, mechanical attachment inside, chemical joining agents outside, so a business building its menu on beaded methods should get the board's reading in writing first.

Plan your menu against that table before you open. The common New Hampshire mistake is a braiding studio that drifts: braid-in and sew-in installs are exempt, clients ask for tape-ins and bonded rows, the studio adds them, and nobody notices the menu crossed into licensed cosmetology months ago. If your menu includes any chemical joining agent, staff it with a cosmetologist and license the premises from day one.

Your space: the shop license

Premises offering licensed work need the shop license under RSA 313-A:19, and operating a shop without one is a misdemeanor. The definition behind it, RSA 313-A:1 XIII-a, is wide: a shop is a barbershop, a mobile barbershop, a salon, and any other business location where barbering, cosmetology or esthetics is practiced. The application names the owner and the shop's address, the license is conspicuously posted, and any licensed barber, cosmetologist, manicurist or esthetician who applies receives it if the shop meets the board's rules, including passing an inspection. The fee is $100 for two years, plus a $100 inspection fee on the initial application, both set in Plc 1002.07. Sanitary inspections follow at initial licensure and biannually thereafter under RSA 313-A:21 II, unless the shop earns the one-time OSHA certificate of ten or more hours in health, safety, disinfection and sanitation that RSA 313-A:19 V offers. When the studio moves, RSA 313-A:19 III provides for a transfer of licensure to the new location.

Two provisions shape how owners structure the purchase. First, you do not need a practitioner license to own the shop. Under RSA 313-A:19 IV, a person who does not practice may hold the shop license if the shop meets every requirement, the fee is paid, and a licensed cosmetologist, barber, manicurist or esthetician is employed as manager; the paragraph does not authorize the owner to practice, so an owner who wants to install bonded hair needs the cosmetologist license as well. Second, the exemption draws the premises line too: a studio whose menu stays entirely inside natural hair braiding practices none of the trades the shop license attaches to, so it needs no shop license, and the moment it adds a licensed service the license attaches to the whole location, with exempt braiders and licensed cosmetologists then working under one roof provided the licensed side is licensed on both levels.

Forming your LLC with the New Hampshire Secretary of State

Most first-time extensions business owners form a limited liability company so the business's debts and legal problems stay with the business instead of following them home. In New Hampshire you form an LLC by filing a Certificate of Formation, Form LLC-1, with the Secretary of State's Corporation Division, online through NH QuickStart, for a filing fee of $100. The legal name must contain "Limited Liability Company" or "LLC", and the filing names a registered agent with a New Hampshire address. The recurring obligation is the annual report: $100, due every year from January 1 through April 1, with a $50 late filing fee after April 1. File the Certificate of Formation before the shop application, because the shop filing names the owner the state already has on record. The full walkthrough is in our New Hampshire hair salon LLC guide.

Registering your business name

A New Hampshire trade name is a state registration, filed with the Secretary of State under RSA chapter 349. Anyone trading under a name other than their own legal name files a registration certificate; the registration is effective on filing for a term of five years; and the fee is $50, with renewals at $50 and a $10 fee for a notice of discontinuance, addition or withdrawal. The registration records your claim to the name; it is separate from forming the LLC, whose own name is fixed in the Certificate of Formation, and it is the filing to make when the sign, the booking page and the bank account will carry a name different from the entity's.

Getting your federal Employer Identification Number

Your EIN is your business's federal tax ID, issued by the IRS, needed to hire employees, open most business bank accounts, and file business taxes. It is free. Apply directly through the IRS and ignore any website that offers to obtain one for a fee. Apply in the LLC's exact registered name and keep the confirmation letter with the entity records. Because New Hampshire does not tax wages, there is no state withholding account to open alongside the federal one.

No sales tax, and the two business taxes instead

Here is the New Hampshire rule that matters most at your register: there isn't one. The state has no general sales tax, so the install appointment, the move-up, the removal and refit, and the hair and take-home products a client buys at the front desk all ring up with no tax added, and no city or town levies one underneath. Extensions businesses sit closer to the retail line than most salons because the hair itself is a product; in a sales tax state that line decides what gets taxed, and in New Hampshire it decides nothing at the register.

The state's claim arrives through two Department of Revenue Administration taxes instead. The Business Profits Tax, RSA 77-A, takes 7.5 percent of taxable business profits, filed only when gross business income passes the threshold, $103,000 for taxable periods beginning on or after January 1, 2023. The Business Enterprise Tax, RSA 77-E, takes 0.55 percent of the enterprise value tax base, the compensation, interest and dividends the business pays, with a filing threshold of $281,000 of gross receipts or of tax base. A payroll-heavy studio can owe BET in a thin-profit year; BET paid is a credit against BPT, with unused credit carrying forward ten taxable periods. Filers also submit Form BT-SUMMARY with Form NH-1040, NH-1065 or NH-1120, due in the spring following the tax year; a studio under both thresholds files nothing.

Hiring stylists, booth renters and workers' comp

When you hire employees, you register as an employer with New Hampshire Employment Security and pay state unemployment tax. The tax is fully employer paid: new employers start at a 2.7 percent rate on the first $14,000 of wages per employee, experience-rated from there, and new hires are reported to the same agency. The wage floor is the federal one: RSA 279 ties the state minimum wage to the federal rate, $7.25 an hour, with overtime at time and one half beyond forty hours, tipped employees paid at 45 percent of the minimum wage with tips making up the rest, and wages paid weekly or every two weeks. There is no state income tax on wages, so there is no withholding to calculate or reconcile. Apprentices sit inside this system: an apprentice is registered with OPLC before training begins under RSA 313-A:24, and her hours are paid employment.

Extensions studios lean heavily on booth rent, and the model works in New Hampshire as long as the licensing layers stay straight: the renter holds her own current personal license, displayed at her work station, inside your shop license, with no booth license of her own since the 2023 repeal. Classification runs on conduct. A true booth renter sets her own prices and hours, books her own clients and collects her own money; if you set a stylist's schedule, prices and menu, the state is likely to see an employee no matter what your paperwork calls her. The host's exposure is statutory: the shop must be under a licensee's direct supervision and management at all times, and employing or allowing an unlicensed person to practice is a misdemeanor under RSA 313-A:9, so verify every renter's license status and scope before her first client.

Workers' compensation is not a choice in New Hampshire. Employers must carry workers' compensation insurance for their employees under RSA 281-A, so the policy belongs in the opening budget rather than on a list of options. That is a genuine contrast with the optional regimes some states run, and it applies from your first hire.

Town zoning, occupancy and local permits

State licenses do not guarantee your location is legal. New Hampshire has no general state business license beyond the licenses in this guide and no statewide municipal license either: land use, building permits, signage and occupancy run through the city or town where the studio sits, under its zoning ordinance and the state building and fire codes as locally enforced. An extensions studio is a commercial use, and the parcel has to allow it before the lease is signed. Where licensed work is offered, the state adds its own premises review on top: the shop license application is inspection-gated, and the license names the address it was issued for. Neither approval substitutes for the other, so confirm zoning with the municipality first, in writing where the town offers it, because build-out and signage are sunk costs by the time a zoning problem surfaces.

Insurance for a New Hampshire extensions business

No provision of chapter 313-A sets a liability insurance minimum for a cosmetologist or a shop, so the coverage stack is a lease and judgment question, with one statutory exception: workers' compensation, which RSA 281-A makes an employer duty rather than a choice. Owners typically shop for general liability, professional liability, and property coverage for the build-out, chairs and retail inventory. Extensions businesses carry one extra inventory exposure: the hair itself is expensive stock, held for specific clients and often prepaid, so ask how your property policy treats client hair stored on the premises. Each booth renter inside your shop license should also carry her own professional coverage, named in the written agreement. Premiums vary widely, so this guide quotes no benchmarks; many landlords require proof of liability coverage as a lease condition, so get quotes before your lease starts. The deeper walkthrough is in our New Hampshire hair salon insurance guide.

Your recurring state costs are small and predictable: license renewals on the two year cycle, the LLC annual report every spring, and business tax returns only above the thresholds. The expensive mistakes in a New Hampshire extensions launch are almost never state fees. They are the lease signed before zoning was checked, the exempt braider booked for bonded installs nobody licensed, and the menu that drifted across the joining agent line.

Dates to put on your calendar

The licenses run on their own two year clocks; the entity report and the tax filings run on the spring calendar underneath them.
