Private Label Hair Growth Serum and Hair Growth Spray

Custom Hair Growth Serum Manufacturing for Your Brand

KINODIN develops and manufactures private label and custom hair growth serums for beauty brands, scalp care companies, salons, distributors and e-commerce businesses. Customers can select an established formula, modify an existing serum base or develop a fully custom formula around peptides, caffeine, rosemary, niacinamide, panthenol and other compatible scalp care ingredients.

Our support covers formula planning, laboratory sampling, texture adjustment, packaging selection, compatibility evaluation, quality control and bulk production. Because ingredient classifications and permitted claims differ between markets, every formula, label and product claim should be reviewed according to the intended country and sales channel before launch.

What Is a Hair Growth Serum?

Hair growth serum is a leave-in scalp care product designed for brands targeting thinning-looking hair, weakened hair, scalp dryness, breakage or reduced hair density.

Compared with traditional hair oils, scalp serums generally offer:

• A lighter texture
• Faster absorption
• Less oily residue
• Controlled scalp application
• Greater flexibility for water-soluble ingredients
• Compatibility with droppers, pumps or other precision applicators
• Premium peptide, vitamin and botanical positioning

A serum can be positioned as a daily scalp treatment, botanical scalp serum, peptide serum, strengthening serum or fuller-looking hair treatment, depending on its formula and the claims permitted in the target market.

Oil-based rosemary, batana and castor blends should be developed separately as private label hair growth oils⁠

, because oil and serum products use different formula structures, ingredients and packaging systems.

Hair Growth Serum Types We Manufacture

KINODIN can develop different serum concepts according to your target consumer, price positioning, distribution channel and ingredient direction.

Lightweight Daily Scalp Serum

A lightweight, fast-absorbing serum is suitable for consumers who want daily scalp care without a greasy finish.

Possible product directions include:

• Hydrating scalp serum
• Daily hair wellness serum
• Lightweight leave-in treatment
• Scalp-balancing serum
• Fine-hair scalp serum
• Non-oily serum for textured or protective hairstyles

The final texture can be adjusted according to the desired absorption speed, residue level and packaging system.

Botanical Hair Growth Serum

Botanical serum concepts are suitable for natural, clean-beauty and wellness-focused brands.

Possible ingredients include:

• Rosemary extract
• Rosemary leaf water
• Ginseng extract
• Ginger extract
• Rice water
• Aloe vera
• Green tea extract
• Nettle extract
• Saw palmetto concepts
• Other compatible plant extracts

Botanical extracts can affect the color, odor, pH and microbial risk of a formula. Each combination must therefore be evaluated as a complete formula rather than added only for label appeal.

Brands seeking an oil-based rosemary product can also explore our private label rosemary hair oil manufacturing⁠

.

Caffeine, Vitamin and Scalp Care Serum

Caffeine can be combined with selected vitamins and scalp-conditioning ingredients to create a modern, lightweight serum concept.

Possible ingredients include:

• Caffeine
• Niacinamide
• Panthenol
• Biotin-oriented concepts
• Amino acids
• Humectants
• Scalp-conditioning ingredients
• Moisturizing ingredients

The concentration and combination of ingredients are determined according to solubility, pH, formula stability and target-market requirements.

Peptide Hair Growth Serum

Peptide-based products are suitable for premium scalp care brands, trichology-inspired collections and advanced hair treatment concepts.

Possible formula directions include:

• GHK-Cu copper peptide serum
• Multi-peptide scalp serum
• Biotinoyl tripeptide-1 concepts
• Acetyl tetrapeptide-3 concepts
• Peptide and botanical combinations
• Peptide, caffeine and vitamin combinations
• Selected branded active complexes, subject to availability

The presence of a premium active ingredient does not automatically guarantee a stable or effective finished formula. Concentration, delivery system, pH, preservative system, packaging and the interaction between ingredients must all be evaluated during development.

Hair Strengthening and Density-Positioned Serum

For cosmetic markets, formulas can be positioned around the appearance and condition of the hair and scalp.

Possible product benefits include:

• Supporting a healthier-looking scalp
• Conditioning dry or uncomfortable scalp
• Helping reduce breakage
• Improving the appearance of weak hair
• Supporting fuller- and thicker-looking hair
• Improving softness and manageability
• Supporting a consistent daily scalp care routine

Final claims must be supported by the formula, available evidence and the regulatory requirements of the destination market.

Three Ways to Develop Your Private Label Serum

KINODIN supports three principal development routes.

Stock Private Label Formula

This route is suitable for startups and brands requiring a faster launch.

Customization can include:

• Brand logo
• Product label
• Bottle and applicator
• Printed box
• Selected fragrance options
• Packaging color and surface finish
• Product size

An established formula generally requires less laboratory development and can offer a more accessible starting quantity.

Modified Existing Formula

This route is suitable for brands that want meaningful differentiation without beginning entirely from zero.

Possible modifications include:

• Adding or removing selected compatible ingredients
• Adjusting texture and absorption
• Modifying fragrance
• Changing product color
• Adjusting the sensory finish
• Selecting a different application system
• Refining the formula for a target consumer group

MOQ, sampling requirements and development time depend on the extent of the requested changes.

Fully Custom Hair Growth Serum

A fully custom formula is suitable for established brands, trichologists, professional scalp care businesses and customers with a detailed technical brief.

Custom development may cover:

• Formula architecture
• Active ingredient selection
• Target ingredient concentrations
• Ingredients that must be excluded
• Scalp feel and absorption speed
• Viscosity and appearance
• Fragrance or fragrance-free positioning
• Packaging and dispensing system
• Target price
• Destination market
• Intended product claims

A fully custom project normally requires a technical review before MOQ, sampling cost and production feasibility can be confirmed.

Copper Peptide, Caffeine and Botanical Compatibility

A formula combining copper peptides, caffeine and botanical extracts requires more than adding the requested ingredients to a standard serum base.

Copper peptides can be sensitive to formula conditions and may interact with certain ingredients. Botanical extracts may also influence pH, color, odor, preservation and long-term appearance.

For this type of custom serum, our R&D evaluation may include:

• Target pH and pH stability
• Ingredient solubility
• Precipitation or sedimentation risk
• Compatibility between peptides and other actives
• Oxidation and color-change risk
• Preservative requirements
• Formula odor
• Viscosity and scalp feel
• Container and dispensing compatibility
• Stability and microbial evaluation

Not every requested ingredient can be used at any requested concentration. The final combination should only be confirmed after laboratory evaluation and sample testing.

This technical approach is particularly important for customers developing formulas around rosemary extract, caffeine, GHK-Cu, niacinamide and panthenol.

Serum Texture and Application Options

The application system should be selected together with the formula. Choosing the bottle after the formula has been completed can cause leakage, poor dispensing, clogging or an inconsistent user experience.

Water-Based Scalp Serum

Suitable for lightweight, fast-absorbing products containing compatible water-soluble ingredients.

Viscous Dropper Serum

Suitable for controlled application to specific scalp areas. Viscosity must remain compatible with the dropper opening and pipette.

Pump Serum

Suitable for convenient daily dispensing and medium-viscosity formulas.

Airless Pump Serum

Suitable for premium positioning and controlled dispensing. Formula viscosity and component compatibility must be tested.

Precision Scalp Applicator

Suitable for applying serum directly between sections of hair. Applicator output and potential clogging must be evaluated.

Packaging and Private Label Options

KINODIN can support bottle selection, labeling, printing and outer packaging for custom hair growth serum projects.

Common packaging options include:

• Glass dropper bottles
• Plastic dropper bottles
• Pump bottles
• Airless bottles
• Precision scalp applicators
• Custom caps and closures
• Printed pressure-sensitive labels
• Screen-printed bottles
• Custom printed boxes
• Protective inserts
• Product instruction leaflets

Common capacities include 30 ml, 50 ml, 60 ml and 100 ml. Other capacities can be evaluated according to bottle availability and order quantity.

Packaging can be customized by:

• Bottle material
• Bottle color
• Surface finish
• Label design
• Logo printing
• Box design
• Applicator type
• Retail channel
• Target price positioning

Packaging compatibility should be evaluated before mass production, especially for formulas containing essential oils, botanical extracts, alcohol, high active levels or ingredients that may interact with the container.

Custom Hair Growth Serum Development Process

Step 1: Submit Your Product Brief

Provide information about:

• Target country
• Target consumer
• Preferred ingredients
• Ingredients to avoid
• Desired texture
• Product size
• Packaging style
• Expected order quantity
• Benchmark product
• Target price
• Launch schedule

A clear brief helps our team recommend the most appropriate development route.

Step 2: Formula and Feasibility Review

Our team evaluates whether the project should use an established formula, modified formula or fully custom development.

The review may consider:

• Ingredient availability
• Supplier minimums
• Solubility
• Formula pH
• Preservative system
• Packaging compatibility
• Manufacturing process
• Testing requirements
• Target-market positioning

Step 3: Laboratory Sampling

Samples are prepared for customer evaluation. The customer can assess:

• Texture
• Absorption
• Residue
• Fragrance
• Color
• Appearance
• Scalp feel
• Dispensing performance

Sample revisions can be planned according to the approved development brief.

Step 4: Formula and Packaging Confirmation

After the sample has been approved, the formula, bottle, applicator, label and box specifications are confirmed.

Artwork should be reviewed before printing to reduce the risk of ingredient-list, usage-instruction or market-claim errors.

Step 5: Bulk Manufacturing and Filling

Bulk production begins after formula approval, packaging preparation and order confirmation.

Production is carried out according to the approved product specification and manufacturing procedure.

Step 6: Quality Inspection and Shipment

Finished products are inspected before shipment. Export and product documentation are prepared according to the agreed project scope.

MOQ, Samples and Pilot Production

What Is the MOQ?

MOQ depends on:

• Stock, modified or fully custom formula
• Raw-material supplier minimums
• Bottle and applicator
• Custom bottle color
• Label or screen printing
• Printed box
• Filling requirements
• Testing plan

Stock formulas generally offer the most flexible starting point. A fully custom formula may require a higher MOQ because it involves dedicated raw-material purchasing, laboratory development and production preparation.

The final MOQ should be confirmed after the formula and packaging brief has been reviewed.

Are Samples Available?

Yes. Samples can be prepared before bulk production.

An existing formula sample usually requires less preparation than a fully custom sample. Custom sample timing depends on ingredient availability, formula complexity and the number of requested variations.

Can You Produce a Smaller Pilot Batch?

A smaller pilot production run can be evaluated for selected projects, including brands that want to validate a new serum in the market before committing to larger repeat orders.

Pilot feasibility depends on:

• Raw-material minimums
• Packaging quantity
• Formula complexity
• Filling equipment
• Production-line requirements
• Testing plan

The unit cost of a pilot batch is normally higher than the unit cost of regular mass production.

What Is the Production Lead Time?

Lead time is confirmed after:

• Formula approval
• Packaging confirmation
• Artwork approval
• Packaging-material arrival
• Deposit or order confirmation
• Testing requirements

Stock packaging and an established formula normally require less preparation than a new formula with custom-printed components.

Quality Control and Testing

KINODIN applies quality-control procedures throughout raw-material inspection, production, filling and finished-product evaluation.

Depending on the selected formula and project scope, quality evaluation may include:

• Raw-material inspection
• Appearance and odor evaluation
• pH testing
• Viscosity testing
• Filling-weight or volume checks
• Microbial testing
• Stability observation
• Packaging compatibility evaluation
• Leakage inspection
• Pump or dropper function testing
• Label and printing inspection
• Finished-product inspection
• Batch traceability

Testing requirements should be determined according to the formula, packaging and destination market.

Documentation and Regulatory Support

Documents vary according to the product, formula and destination market. Depending on the agreed project scope, KINODIN can provide or support relevant information such as:

• Full INCI ingredient list
• Finished-product specification
• Certificate of Analysis where applicable
• SDS or MSDS documentation
• Microbial test information
• Stability information where included
• Manufacturing and quality-system certificates
• Packaging specifications
• Label-information support
• Batch and production information
• Supporting information required for local regulatory review

The United States, European Union, United Kingdom and other markets have different requirements for cosmetic classification, ingredient restrictions, product notifications, safety assessment and marketing claims.

The customer or local responsible party should review the final formula, label and claims before commercial launch.

Products containing regulated drug actives should be managed separately from cosmetic botanical or peptide scalp serums. For example, private label 5% minoxidil hair foam⁠

requires a different regulatory and manufacturing assessment from a cosmetic rosemary or peptide serum.
