How to Start a Hair Extensions Business in Colorado

Colorado answers the extensions question in a place most states never look: its definition of natural hair braiding. A service that puts tension on hair strands or roots by weaving or extending is exempt from the Barber and Cosmetologist Act, so a sew-in through braided tracks needs no license at all. Work that leaves that definition, bonded installs and the cutting and coloring around them, belongs to the cosmetologist license at 50 credit hours or 1,500 contact hours. And the license many guides still point to, the hairstylist license, stopped covering extension application in August 2026. This guide walks through the three positions and the business setup behind them.

Who regulates hair extensions in Colorado

One office runs Colorado beauty licensing: the Office of Barber and Cosmetology Licensure, inside the Division of Professions and Occupations of the Department of Regulatory Agencies, known as DORA. The governing law is the Barber and Cosmetologist Act, Article 105 of Title 12 of the Colorado Revised Statutes, and the office's rules sit at 4 CCR 731-1. Its office is at 1560 Broadway, Suite 1350 in Denver, and applications, renewals and shop registration run online through the Division's portal. Colorado is a mandatory practice act state, so practicing a licensed service without the license is a violation.

The Act licenses five practitioner types: barber, cosmetologist, esthetician, hairstylist and nail technician. For extensions, three corners of that system matter. The cosmetologist license is the broad hair license that carries licensed installation work. The natural hair braiding exemption takes a defined slice of tension based work out of the Act entirely. And the hairstylist license is where a 2026 law change moved the extensions line.

Colorado hair extensions business requirements at a glance

The license question: the cosmetologist license and the hairstylist change

Section 12-105-104(7) defines cosmetology to include arranging, dressing, curling, waving, cleansing, cutting, singeing, lightening, coloring, or similar work upon the hair of a person by any means, with hands or a mechanical or electrical apparatus or appliance, or by the use of cosmetic or chemical preparations, and the definition says the practice includes, but is not limited to, its listed acts. It never names weaving or attaching hair, and it does not need to: an install is work upon the hair by means the definition covers, and the chemical side of the trade, adhesives, bonds and color work outside the braiding definition below, runs on the cosmetic and chemical preparations it names outright.

Training is stated two ways and you need one: 50 credit hours or 1,500 contact hours, a contact hour being at least 50 minutes of instruction, at a school approved by the Division of Private Occupational Schools or the Colorado Community College System. Section 12-105-111 caps the requirement at those totals, sets the minimum age at 16, and lets foreign trained applicants substitute work experience at three months per 100 contact hours, except disinfection and law hours. Rule 1.2 fills in the curriculum topics.

Examination runs through PSI Services, the state's testing vendor, practical first, then theory. PSI charges a $32 application fee, $69 for the practical and $62 for the theory, with retakes at $67 and $60, and the passing score on each is 70 percent. The license fee itself is set by the Director and shown in the Division's portal when you apply; no fixed fee schedule is published.

The hairstylist license is Colorado's narrower hair license, and it is a real license, not an endorsement or a registration. Its training total is 40 credit hours or 1,200 contact hours, 300 contact hours fewer than the cosmetologist, and its curriculum is the hair core of the cosmetology program. Until recently it was also the extensions route on paper: the hairstyling definition at section 12-105-104(9) used to list cutting, arranging, applying hair extensions to, or styling the hair, and older guides and school pages still quote that sentence.

That sentence is gone. The Department's 2025 sunset review recommended removing the reference to applying hair extensions from the hairstyling definition, because, in the Department's analysis, the service is encompassed in natural hair braiding, which is exempt from the Act. The General Assembly enacted the recommendation in House Bill 26-1181, the 2026 sunset bill, effective August 12, 2026. Since that date, applying hair extensions is not a hairstyling service. A hairstylist keeps the rest of the definition, but an extensions menu is not theirs to offer under that license. The office was still revising its rules to match in late 2026.

The braiding boundary: where unlicensed work ends

Colorado deregulated natural hair braiding in 2015, and its definition is why extensions businesses here plan differently. Section 12-105-104(13) defines natural hair braiding as a service that results in tension on hair strands or roots by twisting, wrapping, weaving, extending, locking, or braiding by hand or with a mechanical device, as long as the service does not include hair cutting or 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. Section 12-105-118(1)(d) then exempts the service from the Act: nothing in the Act prohibits services by a person who provides natural hair braiding. Weaving and extending are named in this definition, and nowhere else in the Act's definitions.

Read the definition against an extensions menu and the line draws itself: a sew-in woven through braided tracks, a braid-in install and a crochet install are tension services performed by weaving or extending, by hand or with a mechanical device, so they sit inside the definition and need no license, no course and no registration, the trade our Colorado braiding guide covers in full. The definition then names its own edges. It ends at hair cutting, so the blend cut and shaping of the client's own hair at the end of an install are licensed work even when the install was exempt. It ends at chemistry, so an install held by an adhesive bond, and any service that applies dyes, reactive chemicals, or preparations that alter color or structure, is outside the definition.

Two honest cautions belong on the page. First, no Colorado source sorts installation methods by name, so this guide applies the definition's tests instead: a bonded or taped install fails the chemistry test on its face, while a mechanical install that changes no hair structure stays inside it. If your business rests on a method near that line, get the Director's reading in writing first; Rule 1.11 provides declaratory orders. Second, the exemption is scope, not a title: a braider may not call themselves a cosmetologist or hairstylist, and once the menu adds cutting, coloring or chemical services, the people performing them need licenses.

Your space: shop registration, not a salon license

The space needs its own step, and Colorado's version is lighter than most states. There is no salon establishment license. What the Act requires instead is registration of the place of business, under section 12-105-112 and Rule 1.6: each owner shall register with the Director, and it is unlawful to offer barbering, cosmetology, hairstyling, or esthetician or nail technician services in an unregistered place. Section 12-105-104(14) makes the owner the person responsible for registering. Registration covers permanent, temporary, seasonal and mobile locations, and a licensee's own residence used for services; it is not required of a licensee who works exclusively inside a client's residence or workplace. The fee, like the license fees, is set by the Director and shown in the portal.

The registration makes you responsible for the room. Everyone providing services must hold an active Colorado license and work inside their scope, licenses and the registration are displayed conspicuously, a first aid kit holding at least bandages, gauze and antiseptic stays on the premises, and registration changes and closure notice go to the Director in writing within 30 days. Under Rule 1.10, inspectors may inspect the entire premises, including rented booths. Registering your LLC or trade name with the Secretary of State does not satisfy shop registration; the office has told licensees exactly that.

Booth rent fits inside the registration without multiplying it. A licensee renting a chair inside your registered salon needs no premises filing of their own: one registration covers a place whose booths are offered to the public as a single salon. The exception is written into the same rule: space the public reaches through a separate exterior entrance is a separate place of business and registers on its own. And a braiding only space offers none of the licensed practices, so it files no shop registration until the day it adds a licensed service.

Forming your LLC with the Colorado 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. In Colorado you form an LLC by filing Articles of Organization with the Secretary of State, entirely online, and the fee is $50. The filing names the LLC, its principal address, and its registered agent, who accepts legal papers for the business at a Colorado street address. Colorado has no general state business license, so there is no extra state-level filing beyond the DORA registration above.

Every Colorado LLC then files a Periodic Report each year, on a deadline tied to your own formation date. Your periodic report month is shown on your record in the Secretary of State database, and the report may be filed from two months before that month through two months after it without penalty, for $25 online. Miss the window and a $50 late penalty attaches and the entity goes noncompliant; leave it unfiled and the entity becomes delinquent, and curing the delinquency costs $100. Our Colorado hair salon LLC guide walks through formation in full, and it applies unchanged.

Registering your business name: the statement of trade name

If your studio will operate under a name different from your legal entity name, Colorado calls that name a trade name and you register it with a Statement of Trade Name at the Secretary of State. Under section 7-71-101, a person transacting business under a name other than their true name must file, so an LLC trading under a salon brand, and a sole proprietor working under anything but their own legal name, both file. The filing costs $20, and the Secretary of State's fee schedule also lists a $5 trade name renewal.

The filing has teeth. Section 7-71-102 bars anyone transacting business under an unfiled name from maintaining a court action in Colorado to collect a business debt until an effective statement is on file, and adds a civil penalty of up to $500. A trade name filing is public notice, not a trademark: it gives no exclusive rights. Keep the names consistent anyway: your Secretary of State filings, shop registration, sales tax license and signage should tell one story.

Getting your federal Employer Identification Number

Your EIN is your business's federal tax ID, issued by the IRS, and Colorado keys its registrations to it: the shop registration application asks for the owner's FEIN, and your unemployment and withholding accounts run on it. You also need it for business bank accounts and payroll. It is free. Apply directly through the IRS, ignore any website that offers to obtain one for a fee, and apply early, so the number never bottlenecks a lease signing or payroll setup.

Colorado sales tax: services are not taxed, retail hair is

Colorado taxes retail sales of tangible personal property and only the services its statute names, and hair services are not named, so you collect no state sales tax on installs, move-ups, or removals and refits. Retail product is the opposite, and extensions businesses sit closer to this line than most salons because the hair itself is a product: hair, wefts and take-home care products you sell are taxable retail sales at the 2.9 percent state rate plus local taxes at your address. Buy inventory tax free for resale with the exemption certificate, Form DR 0563, and keep the lines separate at the register: in a mixed transaction bundling taxable products with a service, the entire price may be taxable unless the charges are separated.

The local layer is where Colorado earns its reputation. The Department of Revenue administers the state tax plus the sales taxes of many cities, most counties and a number of special districts, and one license and return cover all of those. But more than 70 home rule cities, including Denver, Boulder, Colorado Springs and Aurora, are self collected, with their own licenses, tax bases, rates and filing rules, so a studio selling retail in one registers and files with the city as well as the state. The state license itself is per location, $16 plus a $50 deposit the Department refunds once you have remitted more than $50 in state sales tax, and licenses expire December 31 of odd numbered years. The Department publishes every jurisdiction's rates in its DR 1002 tables.

Hiring stylists: employees, booth renters and classification

When you hire employees, two accounts open at once. The Form CR 0100 you filed for sales tax also opens your wage withholding account with the Department of Revenue. For unemployment insurance, administered by the Department of Labor and Employment, most employers become liable at $1,500 in wages in a calendar quarter, or one employee for any part of a day in 20 weeks. Premiums are paid on each employee's chargeable wages up to a wage base of $30,600 per employee for 2026, and new employers start on a combined rate of 3.05 percent for 2026. Report every new hire to the Colorado State Directory of New Hires.

The state minimum wage for 2026 is $15.16 an hour, with a tipped cash wage of $12.14 after a tip offset of up to $3.02, and the Department of Labor and Employment has announced $15.71 for January 1, 2027. Cities layer on top: Denver requires $19.29 an hour in 2026, Edgewater $18.17, and the city of Boulder and unincorporated Boulder County $16.82. Colorado also runs FAMLI, its paid family and medical leave program, funded by a premium of 0.88 percent of wages for 2026, split between employer and employee for employers with 10 or more staff. Workers compensation is bought from private carriers; Pinnacol Assurance, the state chartered carrier, writes coverage for employers who cannot get it elsewhere.

Extensions studios lean on booth rent, and the model works as long as the licensing layers stay straight: the renter holds their own active practitioner license, and the space sits under the owner's shop registration. Classification is the trap behind the model: whether a chair renter is an independent contractor or your employee for unemployment insurance turns on control and independent trade under Colorado law, and a lease calling the renter a contractor does not decide it. Paper a real tenancy like one: written lease, set rent that does not float with the renter's revenue, the renter's own prices, hours, clients, products and booking.

City zoning, occupancy and local rules

State filings do not guarantee your location is legal. Zoning controls whether an extensions studio can operate at the address you choose, and cities and counties add occupancy approvals, sign rules and often a local business license on top. Denver layers its own minimum wage and self collected sales tax on top. None of those approvals substitutes for the state filings: the shop registration is written for a specific address and the sales tax license is issued per location, so the address, the lease and the local permission must describe the same room.

Get the zoning answer in writing before the lease is signed. A change of location later is not a formality: the registration, the sales tax account and any city license all move with you.

Insurance and the costs that keep coming back

The licensing office publishes no required insurance amount for a registered shop, so treat insurance as a risk decision and a lease decision rather than a licensing line item. A landlord will name the coverage expected in the lease, and a business working on the public should carry professional liability for the services, general liability for the premises, and property coverage for equipment, furnishings and retail stock. Extensions businesses carry one inventory exposure most salons do not: 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.

Because your chair renters work under your shop registration, your policy should name the arrangement, so a claim arising in a rented chair is not an argument about whose premises it happened on. Our Colorado hair salon insurance guide covers the first employee trigger, the rejection of coverage form for owners, and the $500 a day uninsured penalty on the workers compensation side.

Your recurring state costs are small and predictable: license renewals, the shop registration renewal every other November, sales tax collected and remitted on retail hair and products, and the $25 LLC periodic report. The expensive mistakes in a Colorado extensions launch are the lease signed before zoning was checked, the hairstylist booked for installs the license no longer covers, and the retail hair rung up as an untaxed service.

Dates to put on your calendar

• Every cycle: cosmetologist licenses expire April 30, with the year set by your issuance date and a 60 day grace period after expiration; there is no continuing education requirement for renewal.
• November 30 of odd numbered years: shop registrations expire.
• December 31 of odd numbered years: sales tax licenses expire, per location.
• Every year: LLC periodic report, $25 online, in the window from two months before to two months after your periodic report month.
• On the Department of Revenue's schedule: sales and use tax returns for retail hair and product sales, plus a second city return if you sell in a self collected home rule city.
• Quarterly: unemployment insurance wage reports through the Department of Labor and Employment.
• Before you add a service: recheck the scope rules whenever your menu changes, especially after the August 12, 2026 removal of extension application from the hairstylist definition and while the office's rulemaking following that law is still settling.

General information only, not legal or tax advice. Licensing rules change; confirm your facts with the Office of Barber and Cosmetology Licensure, the Secretary of State, a Colorado CPA, or local counsel before you sign, hire or open.

Frequently asked questions

Do I need a license to install hair extensions in Colorado?

It depends on the method. An install that stays inside the natural hair braiding definition, tension on the hair by twisting, wrapping, weaving, extending, locking or braiding, by hand or with a mechanical device, with no hair cutting and no dyes, reactive chemicals or structure altering preparations, is exempt from the Act and needs no license. Work that leaves the definition, adhesive bonded installs, and any cutting, coloring or chemical service around an install, is licensed work, and the license that carries it is the cosmetologist license.

Can a licensed hairstylist apply hair extensions in Colorado?

Not under the hairstylist license, not since August 12, 2026. The hairstyling definition used to name applying hair extensions, and House Bill 26-1181 removed it, on the Department of Regulatory Agencies' recommendation that the service is encompassed in exempt natural hair braiding. A hairstylist can still perform a tension install that meets the braiding definition, because that service is exempt for anyone, but the install is not a hairstyling service, and bonded installs and the rest of licensed extension work belong to the cosmetologist license.

Is there a specialty hair extensions or weaving license in Colorado?

No. The Barber and Cosmetologist Act licenses five occupations: barber, cosmetologist, esthetician, hairstylist and nail technician. None of them is an extensions or weaving specialty, and there is no braiding license or registration either. The routes are the cosmetologist license for licensed installation work, at 50 credit hours or 1,500 contact hours, and the natural hair braiding exemption for tension installs inside its definition.

Does my extensions studio need a shop registration in Colorado?

If anyone in the space offers a licensed service, yes: the owner must register the place of business with the Director under section 12-105-112 and Rule 1.6, and it is unlawful to offer barbering, cosmetology, hairstyling, or esthetician or nail technician services in an unregistered shop. A space that offers only exempt natural hair braiding offers none of the licensed practices, so no shop registration attaches until it adds a licensed service. Booth renters inside a registered salon do not register separately.

Are hair extension services subject to sales tax in Colorado?

No. Colorado taxes retail sales of tangible personal property and only the services its statute names, and hair services are not named, so you collect no state sales tax on installs, move-ups or removals. Retail product is taxable: hair, wefts and take home products you sell are taxed at the 2.9 percent state rate plus local taxes, and in a self collected home rule city you also register and file with the city. Keep service and product charges separated on the invoice.

How much training does a Colorado cosmetologist need, and what do the exams cost?

Fifty credit hours or 1,500 contact hours at a school approved by the Division of Private Occupational Schools or the Colorado Community College System, and you must be at least 16. Examinations run through PSI: a $32 application fee, $69 for the practical examination and $62 for the theory, taken in that order, with 70 percent required to pass each. The license fee itself is set by the Director and shown in the Division's online portal when you apply.
