Short answer: In most cases, yes - you will need at least a basic business license or registration to sell shampoo bars legally. Selling handmade cosmetics is a real business activity, and almost all local governments require some form of permission before you start selling. The exact permits depend on where you live, where you make the bars, and whether you sell online, in person, or wholesale.
This is general educational information, not legal advice. Always confirm requirements with your city, county, and state agencies.
Why you usually need a business license
A business license is how a city or county gives you permission to operate. Even a small home-based shampoo bar business can trigger local licensing, zoning, and tax requirements. Operating without a required license can lead to fines, penalties, or being ordered to stop selling.
Common registrations for shampoo bar sellers
- Local business license / general business license: Required by many cities and counties, even for home-based and online businesses.
- Sales tax permit / seller’s permit: If your state collects sales tax, you generally need this to collect and remit sales tax on taxable products.
- DBA / fictitious business name registration: If you sell under a name other than your legal personal name, most states require registration.
- State business entity registration: If you form an LLC or corporation, you must register with the state.
- Home occupation permit: If you manufacture at home, your city or HOA may require this to confirm the business is allowed in your zone.
Shampoo bars are cosmetics - not “cottage food”
In the United States, shampoo bars are generally regulated as cosmetics because they are intended to cleanse the hair and body. This is important: cottage food laws that allow home kitchens for baked goods usually do not apply to shampoo bars or other cosmetics.
That does not mean you need an FDA license, but it does mean you are responsible for making a safe product, using appropriate ingredients, following good manufacturing practices, and labeling correctly.
Do you need an FDA license or approval?
No. The U.S. Food and Drug Administration does not issue cosmetic licenses and does not approve shampoo bars before they go to market. However, you must still comply with FDA rules. Your product must be safe, not adulterated or misbranded, and properly labeled with ingredients, net weight, and responsible party information.
If you make drug-like claims - such as “treats dandruff,” “kills fungus,” or “prevents hair loss” - the product may be classified as an over-the-counter drug, which brings additional FDA drug regulations.
State and local cosmetic manufacturing rules
Some states require cosmetic manufacturers to register separately or follow specific facility rules. Check with your state’s department of health, agriculture, or consumer affairs. Search for terms like “cosmetic manufacturer registration” plus your state name.
What about selling online or on Etsy, Shopify, or Amazon?
Selling through a marketplace does not replace your local business license. You generally still need to register your business and comply with sales tax rules. Many marketplaces now collect sales tax on your behalf, but you may still need a seller’s permit or state registration depending on where you are located.
Other practical requirements to plan for
- Product liability insurance: Strongly recommended for anyone selling cosmetics, including shampoo bars.
- Cosmetic labeling compliance: Ingredient lists using INCI names, net weight, and responsible party information.
- Good manufacturing practices: Keep records, use clean equipment, and follow consistent recipes.
- Zoning and landlord approval: If you rent or live in an HOA, confirm you can operate a home business.
If you are outside the United States, the names of the permits may differ, but the principle is similar. Many countries also have cosmetic product notification or “responsible person” requirements, so check your national and local rules.
How to find your exact requirements
- Check your city or county website for a general business license application.
- Visit your state department of revenue to see if you need a sales tax permit.
- Search your state’s cosmetic or manufacturing rules to see if additional registration applies.
- If you form an LLC or corporation, register with your secretary of state.
- Talk to a local accountant or small business attorney for a quick compliance review.
Bottom line: Assume you need a business license. Shampoo bars are legitimate cosmetic products, and selling them is a business. Getting the right license is usually inexpensive and straightforward, and it helps you operate legally, collect sales tax properly, and build a credible brand.
