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

Missouri never wrote the word weaving into its cosmetology law, and that silence shapes the whole launch. There is no extensions specialty license and no scope paragraph that names attaching hair. What the law gives you is two hair licenses, the Class CA cosmetologist and the Class CH hairdresser, and one much lighter door: a $20 hair braiding registration whose statutory definition includes extending and stops at chemistry. This guide walks through where each route reaches and the establishment license behind the chair.

Who regulates hair extensions in Missouri

One board runs Missouri beauty licensing: the Board of Cosmetology and Barber Examiners, inside the Division of Professional Registration in the Department of Commerce and Insurance. The board works under Chapter 329 of the Missouri Revised Statutes and its rules at 20 CSR 2085, and it handles applications through MOPRO. Extension work is not carved out anywhere in that chapter. No Missouri statute, rule or board publication names sew-in weaves, tape-ins, fusion bonds or microlinks, and the board publishes no method list that sorts install techniques into licensed and unlicensed piles.

That means the licensing answer is built from the texts that do exist: the classified occupation definitions in section 329.010, the hair braiding registration in section 329.275, and the establishment license in section 329.045. Read those three sections before anything a school or a supplier tells you. The rest of your setup spreads across the Secretary of State, the Department of Revenue and the Department of Labor and Industrial Relations, and your city adds a local layer on top.

Missouri hair extensions business requirements at a glance

The license question: Class CA, Class CH, or the braiding registration

Missouri licenses hair work through the classified occupations listed at section 329.010(5), and the list is short. Class CH, the hairdresser classification, covers arranging, dressing, curling, singeing, waving, permanent waving, cleansing, cutting, bleaching, tinting, coloring or similar work upon the hair of any person by any means, plus scalp and related services. Class CA, the cosmetologist classification, is defined as including all practices of cosmetology in the hairdresser paragraph and the manicurist paragraph, so it is the Class CH hair scope plus manicuring.

Read those scope paragraphs closely, because what they omit decides this guide. Neither scope names weaving, attaching hair, extensions or wefts. Missouri has no specialty license for extensions or weaving: the four classifications in section 329.010(5) are the whole menu. An extensions business here is built on a general hair license, not a dedicated one. In practice the Class CA is the safer foundation for a full service studio, because install work rarely travels alone: the client who books a sew-in also books the takedown, the blend cut, the color match and the treatment, and every one of those sits squarely inside the licensed scopes, A Class CH hairdresser covers the same hair services and stops where nails begin.

The training statute prescribes one course of study for the cosmetology classifications. Under sections 329.040 and 329.050, the cosmetologist course runs at least 1,500 hours in a licensed school, or at least 1,220 hours in a public vocational technical school, with at least 160 hours of classroom training before a student may work on the public, and the apprenticeship route runs 3,000 hours. Applicants must be at least 17, hold education equivalent to completing the tenth grade, and pass an examination. Missouri outsources the exams to Prov: the written examination costs $90 and the practical $60. One caution: the statute states the hours for the cosmetologist classification, prescribes a single curriculum, and states no separate, shorter course length for Class CH, so check any different Class CH number against the statute itself.

Selling hair is a different matter from installing it. Nothing in Chapter 329 licenses retail: a shop can sell bundles, wefts, clip-ins and take-home products as merchandise with no cosmetology credential, and the license question attaches to the service performed on a client's head, not to the hair on the shelf. The tax side of that shelf is real, though, and the sales tax section below covers it. Our Missouri hair salon guide walks through the cosmetologist license step by step.

The braiding boundary: where registered work ends

The lighter door is real, and it is narrower than it looks. Section 329.275, enacted in 2018, took hair braiding out of cosmetology and barbering and replaced the license with a registration. No person may braid for compensation in Missouri without first registering with the board. The board charges $20, the statutory cap. Before the certificate issues, the applicant must watch the board's instructional video, which the statute sets at at least four and no more than six hours, covering infection control techniques and diseases of the scalp. A registered braider posts the certificate conspicuously at the place of business, or hands the client a copy on request when working elsewhere, and the board may inspect a braiding facility once a year, and on complaint, and may suspend or revoke the certificate of a registrant who works outside the braiding scope.

Everything turns on the definition at section 329.010(9). Hair braiding is the use of techniques that result in tension on hair strands or roots by twisting, wrapping, waving, extending, locking, or braiding of the hair by hand or mechanical device, and it 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. Two features of that sentence carry the extensions question. First, extending is expressly in the list: tension based work that lengthens hair sits inside the definition in so many words. Second, the list says waving, not weaving. and the statute never uses that word for the sew-in weave braiders most want it to cover. The board publishes no ruling, FAQ or method list that resolves the gap, and no Missouri source we could read sorts sew-ins, tape-ins or bonded methods by name.

So the honest map of the boundary has three zones. Work that attaches added hair using only the named tension techniques, with no chemistry, is the strongest fit for the registration, and braid based installs live there. Work that crosses into dyes, reactive chemicals or structure altering preparations is outside the definition on its face, and cutting a client's own hair is Class CH scope work however the install was attached, so both belong to a licensee. And the middle, a business whose whole menu is sew-in weaves performed by a registrant, rests on reading "extending" to cover a technique the definition does not name. That may well be the board's practice, but it is not written down. If that is your model, write to the board before you sign a lease, describe the exact methods you will use, and keep the answer with your certificate. Our Missouri braiding guide covers the registration itself in full.

Your space: the cosmetology establishment license

The premises are licensed separately from the people. Section 329.010(6) defines a cosmetology establishment as that part of any building where a classified occupation is practiced, expressly including any space rented within a licensed establishment, and section 329.045 requires every establishment to hold an establishment license, posted in plain view. The fee rule at 20 CSR 2085-3.010 prices the application at $100 for an establishment with up to and including three operators, plus $10 for each additional operator, so a four chair studio pays $110 and a ten chair studio pays $170. Renewal is $75, reinstatement after a lapse is $105 including the late fee, and opening unregistered draws a $100 delinquent fee. The establishment license holder does not have to be a cosmetologist, so a non-licensee can own the shop.

The license is tied to the owner and the address. A change of ownership or location requires a new license within 45 days: a change of location costs $100 for a full service establishment, a change of ownership costs $100, and adding a co-owner costs $50. A buyer does not inherit your license; price the refiling into any purchase or relocation. Missouri also answers the booth rent question inside the same fee rule: a stylist who rents a station as her own business holds a rental station establishment license, $100 to open, $75 to renew and $50 to move, on top of her own operator license. Renting a chair as part of someone else's establishment works the other way: the salon's license covers the premises, and the renter is counted in its operator total. A premises that does registered hair braiding only needs no establishment license, because section 329.275 takes braiding out of cosmetology, though the board keeps its once a year inspection right over braiding facilities.

Forming your LLC with the Missouri Secretary of State

Most Missouri extensions studios form as an LLC, and Missouri prices the form at the bottom of the national range. The Articles of Organization, Form LLC 1, are filed with the Secretary of State's Corporations Division under Chapter 347 and cost $50 filed online or $105 on paper. An optional name reservation holds a name for $25, and a certificate of good standing costs $10. The reporting position is where owners importing habits from other states go wrong: a Missouri LLC files no annual report with the Secretary of State. The annual registration report belongs to corporations, due in the incorporation month at $20 online or $45 on paper. So the LLC's recurring Secretary of State bill is zero, and the calendar item that replaces the annual report is the fictitious name renewal below. The Secretary of State registers your entity; the board licenses your people and your premises; the two systems do not talk to each other. Our deeper guide, forming a Missouri salon LLC, covers the filing sequence in full.

Registering your business name as a fictitious name

Missouri calls its trade name filing a registration of fictitious name, filed with the Secretary of State under Chapter 417 by every kind of business, sole proprietors included. If your studio trades under any name other than the legal name of you or your entity, you register that name for $7; creation, renewal, correction and amendment all cost the same $7, and cancellation is free. Section 417.210 asks for the registration within five days of first using the name, which makes it an opening week filing. The registration runs five years, and the renewal must be filed within the six months before the five years run out. The registration is a public notice filing, not a license or a trademark, and it does not stop anyone else from using the name. Keep the name on the registration, the establishment license application and your signage telling one consistent story.

Getting your federal Employer Identification Number

With the entity filed, get an Employer Identification Number from the IRS. It is free, issued directly by the IRS, and it is the number your business bank account, your Department of Revenue registrations and your payroll accounts will all key off. An LLC needs one the moment it hires, opens payroll or wants business banking separated from a Social Security number. Apply on the IRS site and be wary of paid services dressed up to look official: the number itself costs nothing. Open the business bank account as soon as the EIN exists and run every fee, product order and rent payment through it; extensions work runs on deposits and balances across long appointments, and a clean account makes the money side provable at tax time.

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

Missouri draws the salon tax line at the register. The tax falls on retail sales of tangible personal property and on the specific services the statutes name, and haircutting, coloring, styling and installation work are not named, so you do not collect sales tax on service receipts. Product is different: bundles, wefts, shampoo and anything else a client takes home is a retail sale, taxed at the combined state and local rate for your address. Itemize services and products separately at checkout and the tax follows the product lines only, which matters when a ticket mixes a large hair purchase with a larger install fee.

Any business making retail sales needs a Missouri retail sales license before its first sale, and the Department is blunt about the order of operations. Registration runs through the Department's online system or on Form 2643, the Missouri Tax Registration Application, and the same form opens your employer withholding account when you hire. The Department's guidance prices the mistake of selling first and registering later: a penalty of $500 for the first day of unlicensed selling and $100 for each day after, up to $10,000, under section 144.118, and operating without the license is a misdemeanor. Register before the doors open. If financing the opening is part of the plan, our Missouri business loans guide covers the state programs lenders actually use.

Missouri taxes on the business itself

Missouri keeps the entity level light for the form most studios choose. An LLC pays no franchise style tax to the state and files no annual report with the Secretary of State, so there is no yearly state fee for existing. The income tax position follows the form you chose: a single member LLC and a partnership taxed LLC report on the owners' returns, while a corporation files its own, and the Department of Revenue's withholding registration on Form 2643 is the filing that actually recurs once you have staff, because wages trigger withholding from the first paycheck.

Hiring stylists: employees, booth renters and workers' comp

Your first hire registers you as an employer in two places. The Department of Revenue takes your withholding registration on the same Form 2643 that opens the sales tax account. The Division of Employment Security runs the unemployment insurance account: liable employers report wages and pay contributions quarterly, and no part of the tax may be deducted from a worker's pay. A new employer pays the new employer rate for its first two or three years; the Division's published table puts the 2026 rate for most new employers at 2.376 percent, on the first $9,000 of each employee's wages per year, capping the new employer cost at about $214 per employee per year before experience rates of 0.0 to 6.0 percent take over. The wage floor matters as much as the tax: Missouri's minimum wage for 2026 is $15.00 an hour under section 290.502, tipped employees must be paid at least half that, $7.50, in cash, and overtime runs at one and one half times the regular rate past 40 hours. One exemption is worth knowing: the state rate does not apply to a retail or service business with annual gross sales under $500,000, although federal law may still set a floor.

Booth rent is where extensions studios most often misclassify people. The rental station license settles the board's side of the question; it does not settle the tax side. Whether a renter is an independent contractor or your employee is answered under the control based tests the IRS and the Division of Employment Security apply to the actual arrangement: whose clients they are, who sets prices and hours, who collects the money. A written rental agreement is evidence, not a verdict. Paper a real tenancy like a tenancy: a lease, a set rent that does not float with her service revenue, her own fictitious name registration and her own tax accounts. Our booth rent calculator helps price a station against the salon's costs.

City zoning, occupancy and local permits

The local layer sits underneath the state licenses and can still stop a launch. Your city controls zoning, and a salon has to be a permitted use at the address you choose; confirm that with the city before you sign the lease, and ask what the build out will require. Cities and counties across Missouri issue their own business licenses and occupancy permits, and the larger metros layer their own tax registrations and inspections on top, with fees and sequences that differ enough between a Kansas City storefront, a St. Louis shop and a small town main street that no state guide can price them for you. Get the zoning answer and the inspection sequence in writing before the lease is signed: every state license in this guide is issued for a specific address, an establishment move triggers a new license filing inside 45 days, and the application fee is spent whether the space works out or not.

Insurance and the costs that keep coming back

The board publishes no required insurance amount for a cosmetology establishment, so treat insurance as a risk decision and a lease decision rather than a licensing line item. A landlord will name the coverage he expects in the lease, and a business working on clients should carry professional liability for the services themselves, general liability for the premises, and property coverage for equipment and retail stock. Extensions work concentrates value: one appointment can put hundreds of dollars of hair and hours of labor on one head, so the professional liability conversation should name install services and adhesive reactions expressly. The one coverage Missouri law can require is workers compensation, mandatory at five or more employees; officers of a corporation and members of an LLC count toward the five, and part time and family member employees count too, while sole proprietors and partners do not. Our Missouri salon insurance guide works through the five employee trigger in full.

Dates to put on your calendar

• September 30 of every odd numbered year: every board license and registration expires, operator, establishment and braiding registration alike. A renewal postmarked after that date is returned and the licensee reinstates instead, at $90 for an operator inside two years.
• Within 5 days of first using your trade name: fictitious name registration with the Secretary of State, $7, then renew inside the six months before its five years run out.
• Within 45 days of buying, selling or moving the studio: new establishment license filing with the board.
• Quarterly: unemployment wage reports and contributions to the Division of Employment Security, and sales tax returns at the frequency the Department of Revenue assigns.
• Not on your calendar: an annual report to the Secretary of State. Missouri LLCs do not file one.
• Before you add a service: recheck the scope paragraphs in section 329.010 whenever your menu changes, especially before adding adhesive installs, cutting or chemical services under a braiding registration.

Frequently asked questions

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

For most install work, yes. Missouri licenses hair work through the classified occupations in section 329.010(5): the Class CH hairdresser scope and the Class CA cosmetologist scope, which includes the hairdressing scope plus manicuring. Neither scope names weaving or attaching hair, and Missouri has no specialty extensions license, so a licensed cosmetologist or hairdresser working in a licensed establishment is the defensible route for installs. The one lighter route is the hair braiding registration under section 329.275, and it reaches only work inside the braiding definition.

What is the difference between the Class CA and Class CH licenses in Missouri?

Scope, not hours. Class CH is the hairdresser classification: arranging, dressing, curling, waving, cutting, bleaching, tinting, coloring and similar work on hair, plus scalp and related services. Class CA, the cosmetologist classification, includes everything in the Class CH scope plus manicuring. The statute prescribes one cosmetology course of study, at least 1,500 hours in a licensed school or 1,220 hours in a public vocational technical school, or 3,000 hours as an apprentice, and it states no separate shorter course for Class CH.

Can I install extensions with just the hair braiding registration in Missouri?

Only where the work stays inside the statutory definition of hair braiding: techniques that result in tension on hair strands or roots by twisting, wrapping, waving, extending, locking or braiding, by hand or mechanical device. The definition expressly includes extending, and it expressly excludes dyes, reactive chemicals and preparations that alter the color or structure of the hair. Registration costs $20 and requires watching the board's instructional video, which runs four to six hours. The definition says waving, not weaving, and the board publishes no ruling that sorts install methods by name, so get the board's reading in writing before building a business on the registration alone.

Does Missouri have a specialty license for hair extensions or weaving?

No. Section 329.010(5) lists four classified occupations of cosmetology: Class CH hairdresser, Class MO manicurist, Class CA cosmetologist and Class E esthetician. None of them is a weaving or extensions classification, and no scope paragraph in the section names weaving, attaching hair, extensions or wefts. Missouri's answer to extension work runs through the cosmetology and hairdresser licenses and, at the lighter end, the hair braiding registration.

What license does an extensions studio itself need in Missouri?

A cosmetology establishment license under section 329.045, because the studio is space where a classified occupation is practiced. The application is $100 and covers up to and including three operators, with $10 for each additional operator; renewal is $75, and every license expires September 30 of each odd numbered year. A stylist renting a station as her own business holds the rental station form of the establishment license, $100 to open and $75 to renew. A premises that only does registered hair braiding needs no establishment license, because section 329.275 takes braiding out of cosmetology.

Are hair extension services subject to sales tax in Missouri?

No. Missouri taxes retail sales of tangible personal property and the specific services the statutes name, and hair services are not named, so you do not collect sales tax on installation receipts. Hair, wefts and products a client takes home are retail sales and are taxed at the combined rate for your address. You need a Missouri retail sales license before your first retail sale; register on Form 2643 or online with the Department of Revenue.
