R&D and Sampling: Turning Brand Ideas into Mass-Producible Products
From requirements communication and formula selection to sample confirmation — a solid development phase determines whether a new product can successfully reach the market.
When buyers first contact a hair color manufacturer, the first question is almost always: "When can you ship?" But what truly determines the delivery date is whether the R&D and sampling phase is solid.
Before mass production begins, every new product must complete formula confirmation, color testing, hair strand verification, and packaging compatibility checks. Any step handled carelessly means far higher correction costs after mass production than during sampling. Mingli's R&D team doesn't just "make samples" — they help clients identify and resolve every potential risk at the lowest-cost stage of the partnership.
01 — Why it matters
Why the R&D Phase Determines the Success of the Entire Partnership
Whether you are developing a hair color shampoo, a dual-component hair dye cream, or a fashion shade line, the upstream development decisions made during sampling cascade through every downstream stage: procurement, production scheduling, compliance documentation, and ultimately your retail launch date.
Skipping steps or rushing approvals to "save time" is the most reliable way to lose it. A reformulation after mass production doesn't just cost money — it resets your entire timeline and forces rework on packaging, labels, and compliance dossiers already in progress.
"The extra time spent upfront on a solid sample confirmation avoids the far greater cost of large-scale rework after mass production."
This is the principle behind Mingli's development workflow: no mass production starts until samples are formally confirmed. Every step below is designed to front-load the decisions that matter most.
02 — Project brief
Step 1: Turn Vague Ideas into a Clear Project Brief
Every project begins with a systematic consultation. A vague reference image or a color name is rarely enough to build a specification around. The Mingli business team works through a structured set of questions before a single formula is pulled from the library.
What the consultation covers
-
Product type — hair color shampoo 2-in-1, dual-component hair dye cream, fashion hair color, or beard color?
-
Target market — Europe, the Middle East, Southeast Asia, Africa, or the Americas. Different markets have significantly different requirements for color, formulation, and compliance standards.
-
Color direction — dark shades for gray coverage, fashion color series, or beard-specific shades?
-
Packaging preference — bottle, sachet (single-use), tube, or kit combination?
-
Budget and MOQ — to assess which customizations are cost-viable upfront. As a dedicated hair color ODM partner, we help you find the right balance for your margin structure.
-
Launch timeline — to reasonably prioritize R&D and production scheduling.
After confirming all requirements, the team compiles a written project brief that becomes the unified reference for sampling, quotation, and production. This single document significantly reduces the rework and miscommunication that derail projects later — and sets a clear benchmark against which every sample is evaluated.
03 — Formula & color
Step 2: Formula Selection and Color Direction
Mingli's R&D center spans over 200 square meters and maintains a formula library covering hair color shampoos, dye creams, conditioners, and beard products, continuously optimized by a team with over 10 years of experience. As a trusted hair color manufacturer and wholesale manufacturer, we give clients two paths forward:
Select from existing formulas
Fastest path to market. Choose a proven base, adjust shade, fragrance, or functional ingredients, and proceed to strand testing within days. Ideal for distributors adding new SKUs to an existing line.
Customize within parameters
For brands building a differentiated product story. Work with our team to develop shades, textures, and ingredient profiles that match your positioning — from salon-grade dye creams to gentle color shampoos.
What can be adjusted
Color — deepen, lighten, or develop entirely new shades, including fashion colors and targeted black hair shampoo formulations for high-coverage gray results.
Texture and formulation — lighter rinse-off, thicker cream-based, or liquid depending on the application format. Hair color cream and shampoo formats have different viscosity targets.
Fragrance — fresh floral, herbal neutral, or minimal scent for markets sensitive to strong chemical smells.
Functional ingredients — Argan Oil, ginseng extract, olive oil, and other botanicals that support your brand narrative around nourishing or hair care positioning.
For fashion hair colors, the R&D team evaluates actual color results based on the target base color and usage scenario to avoid color inconsistencies across different hair types — a detail that is easy to miss at the brief stage and costly to fix at scale.
04 — Lab samples
Step 3: Lab Samples and Hair Strand Testing
Once formula direction is confirmed, the lab prepares small batch samples and runs preliminary checks on appearance, color, scent, and basic physicochemical indicators. For all hair dye cream and hair dye shampoo products, this stage includes hair strand testing.
Small batch preparation
The lab produces a sample batch using the confirmed formula parameters. Appearance (color, clarity, separation), scent profile, and initial viscosity are assessed before any external review.
Physicochemical verification
Basic indicators — pH, viscosity, stability under temperature — are checked against the product specification. For a hair color supplier shipping to regulated markets, these benchmarks are also the starting point for compliance documentation.
Hair strand testing
The product is applied to real hair strands to observe the coloring effect, shade uniformity, and gray coverage. This is where formulation decisions made on paper meet reality — and where adjustments are cheapest.
Photo documentation and client review
Strand test photos and sample images are sent to clients so they can evaluate whether the color matches expectations before seeing the physical product. Clear, specific feedback at this stage shortens the revision cycle significantly.
This four-stage sequence is what separates a thorough hair dye ODM process from a factory that ships a batch and hopes for the best. The photographs give clients a concrete reference for shade, coverage, and texture — and give our team a clear target for any revision.
05 — Physical sample
Step 4: Sample Shipment and Client Confirmation
Physical samples are couriered to the client. This is the stage where the full user experience is evaluated — not just the color result on a strand chart, but how the product actually behaves in real use conditions.
Application feel and coloring results — does the texture distribute evenly? Does the shade match the strand photos? How does coverage perform on resistant gray hair?
Scent in context — fragrance reads differently in a small lab sample vs. a freshly opened bottle in a heated bathroom. This is when scent adjustments, if needed, are easiest to make.
Texture under temperature and humidity variation — a hair color cream that performs well in one climate can behave differently in another. Markets across Southeast Asia, the Middle East, and Africa often have divergent requirements here.
No mass production starts until samples are confirmed. The extra time spent upfront on sample confirmation avoids the far greater cost of large-scale rework. Once the formula, shade, and user experience are signed off, the project proceeds to packaging design, material preparation, and production scheduling via our standard production process.

Common Sampling Q&A
How long does sampling take?
Typically 3 to 7 business days, depending on formula complexity and feedback speed. Urgent timelines can be flagged in advance for priority arrangement. Contact the team early if your launch window is tight.
Are samples paid?
This depends on the project scope and product type. We recommend confirming the current sampling policy via the website inquiry form or directly with the business team.
Can multiple shades be sampled at the same time?
Yes. When planning to launch a range — for example, a black hair shampoo line alongside dark brown and natural black variants — developing them in the same batch makes comparison and overall range confirmation much easier. This approach also helps your hair color ODM partner align packaging timelines across the full SKU set.
How many revision rounds are supported if I'm not satisfied?
Reasonable adjustments based on client feedback are supported. Specific feedback is much more efficient than general dissatisfaction — for example: "too red in warm light," "coverage breaks down at 10% gray," or "texture is too thin to cling on wet hair." Precise input helps the R&D team pinpoint the issue and resolve it in fewer rounds.
What if I want to add shades after the first mass production run?
It is always more efficient to confirm all shades during the sampling phase rather than adding them incrementally after mass-producing the first. Developing them together unifies the packaging rhythm and better controls overall cost and timeline for wholesale hair color programs.
When developing a wholesale hair dye line with multiple shades, confirm all colors during the sampling phase rather than iterating one shade at a time. A hair dye wholesaler adding three new SKUs to an existing catalog can save weeks by running parallel strand tests and confirming shades as a group — even if the production plan staggers the launch dates.
