Private label hair conditioner is conditioner made by a contract manufacturer and sold under your brand, usually alongside a matching shampoo. Minimums run from none at all to a few hundred units or a set volume, depending on the maker and whether you use their stock formula or a custom one. The rules are mostly cosmetic rules, with two exceptions that catch new brands out: anti-dandruff products and hair growth claims are regulated as drugs.
Below: the three ways to source, real published minimums, how to vet a manufacturer, the claims line, what “organic” can and cannot mean, and how to sell the line on Amazon.
Three ways to build the line
- Stock formula with your label. Fastest and cheapest. Good for testing whether your brand angle sells.
- Stock base, customized. The maker adjusts fragrance, oils or actives within an existing base. A common middle path.
- Custom formula. Built for a specific hair type or ingredient story, such as curly or textured hair, color-treated hair, or a fragrance-free line. Higher minimums, more time, but harder for competitors to copy.
My view: start with a matched shampoo and conditioner pair on a customized base. Pairs sell together, and one strong pair teaches you more than five half-finished SKUs.
What minimums look like
From manufacturers’ own published terms:
| Manufacturer | Published minimum |
|---|---|
| Tropical Products (Massachusetts) | No minimum order quantity for private label shampoo solutions |
| Shay Labs (Illinois) | Minimums begin at 500, with free R&D and formulation services |
| RainShadow Labs (Oregon) | 10 gallons for private label stock; custom formulations from 25 gallons |
Volume minimums need converting. Ask how many units of your bottle size a batch fills, then price the whole run, including bottles, pumps and labels, not only the liquid.
How to vet a hair care manufacturer
- Formula ownership. Who owns a customized or custom formula? Get it in the contract.
- MoCRA registration. Is the facility registered with the FDA?
- Documents. Can they supply a GMP certificate and a Certificate of Analysis? Amazon asks for both in beauty.
- Stability and compatibility testing in your chosen bottle, with your pump.
- Preservation. Water-based products need a preservative system. Ask what they use and how it was tested.
- Claims support. If you plan claims such as “sulfate-free” or “for curly hair”, can they back them with the formula?
When you compare samples, use them for two weeks the way a customer would. Rinse feel and scent after drying matter more than the first impression in the shower.
Cosmetic or drug: where the line sits
The FDA classifies by intended use. Its own examples are direct:
| Product or claim | FDA category |
|---|---|
| Cleansing shampoo, conditioner | Cosmetic |
| Anti-dandruff shampoo | Cosmetic and drug (it cleanses, and it treats dandruff) |
| Claims that a product will restore hair growth | Drug |
So a “hair growth serum”, one of the most searched private label hair products, is a drug if it claims to grow hair. That means OTC drug rules or approval, not cosmetic rules. I’d keep a first line strictly cosmetic: cleanse, condition, detangle, add shine, smell good.
“Organic” hair care: what you can say
The FDA does not define “organic” for cosmetics. The USDA’s National Organic Program does not regulate the word for cosmetics either, but a personal care product made with agricultural ingredients that meets USDA organic standards is eligible for the same organic labeling categories as other agricultural products, including the USDA Organic seal. In short: “organic” on a shampoo is only meaningful if the product is certified under the USDA program. Without that, I’d avoid the word and name the specific organic ingredients instead.
Your duties under MoCRA
As the brand on the label, you are typically the responsible person. Duties include listing each product with the FDA (with ingredients, updated annually), reporting serious adverse events within 15 business days, keeping safety substantiation records, and printing US contact information on the label. Manufacturers register facilities every two years.
Small businesses with average US cosmetic sales under $1 million a year over the previous three years (inflation adjusted) are exempt from GMP, registration and product listing requirements, according to the FDA. Adverse event reporting and labeling still apply. Our guide to private label skin care explains MoCRA in more detail.
Selling the line on Amazon
Amazon’s beauty guide lists the documents it may request: invoices showing the purchase of 10 or more units, a GMP certificate, a Certificate of Analysis and MoCRA compliance documentation. It also prohibits claims that a product diagnoses, cures, treats or prevents disease without FDA approval, which rules out anti-hair-loss promises on a cosmetic.
Hair care on Amazon is competitive. In practice, brands win on a clear audience (curly hair, color care, men’s grooming, fragrance-free), strong images that show texture and results within cosmetic limits, and bundles of the shampoo and conditioner pair. Our list of private label manufacturers in the USA covers vetting makers in other categories.

FAQ
What is the minimum order for private label shampoo and conditioner?
It ranges from no minimum at some US makers to a few hundred units or a set volume at others. One Illinois manufacturer publishes minimums starting at 500; an Oregon maker sets 10 gallons for stock private label.
Is private label shampoo regulated by the FDA?
Yes. Shampoo and conditioner are cosmetics under FDA rules and MoCRA. Anti-dandruff shampoo is also a drug, and products claiming to restore hair growth are drugs.
Can I call my private label conditioner organic?
Only meaningfully if it meets USDA organic standards and is certified. The FDA does not define “organic” for cosmetics.
Can I sell a private label hair growth serum?
If it claims to grow or restore hair, the FDA treats it as a drug, which brings drug requirements. A cosmetic serum can claim shine, smoothness or reduced frizz instead.
What documents does Amazon need for hair care?
Amazon may ask for invoices for 10 or more units, a GMP certificate, a Certificate of Analysis and MoCRA documentation, depending on the product.
Should I launch shampoo and conditioner together?
In my view, yes. A matched pair sells as a set, shares branding costs, and lets you bundle on Amazon.
