KD3802 LED Microcurrent Scalp Massage Comb
The KD3802 is a rechargeable scalp massage comb combining LED modes, adjustable microcurrent output, vibration and a removable liquid reservoir. Brands and importers can review the controls, liquid compatibility and sample configuration before confirming private label requirements.
- LED modes and five output levels; confirm the mode-to-control mapping for the selected version
- Vibration massage and elastic metal contact teeth
- Removable liquid reservoir for approved compatible formulations
- Sample evaluation before electrical, accessory and private label approval
Product Fit for Scalp-Care Ranges
Compare the rechargeable format, liquid-assisted concept and user-instruction requirements with the needs of your scalp-care range.
Rechargeable Scalp-Care Devices
Consider this platform when your product range needs a rechargeable scalp massage comb with adjustable controls and a liquid reservoir. Evaluate the actual sample before approving the product description and commercial configuration.
Liquid-Assisted Product Concepts
A reservoir-based product requires review of the intended liquid, dispensing behavior, residue and cleaning instructions. Compatibility must be established for the proposed formulation and product version.
Retail Presentation & User Instructions
Align demonstrations, packaging and instructions with the approved functions and permitted use. Distribution through professional channels does not establish suitability for treatment services or continuous salon operation.

LED Modes, Microcurrent Controls & Liquid Reservoir
Review the output controls, LED modes, vibration, contact teeth and reservoir as separate functions. Their presence does not by itself establish hair-growth or treatment outcomes.

Adjustable Microcurrent Controls
The reference controls provide five output levels within the selected mode. Match the mode labels and switching sequence to the approved instructions; these levels are not five LED brightness settings.
LED Modes & Vibration
The reference instructions distinguish operating modes associated with red and blue LEDs, alongside a separately controlled vibration function. Confirm the intended application of each mode; do not describe every mode as a scalp routine.
Elastic Metal Contact Teeth
The elastic metal contact teeth form part of the contact interface. Review tooth alignment, spring-back, end finish and assembly on the supplied sample, following its permitted use conditions.
Removable Liquid Reservoir
Confirm the intended formulation and reservoir instructions before use. The reviewed English manual excludes essential oils and powdered formulations; a liquid reservoir does not establish compatibility with every scalp-care liquid.
Scalp Massage Comb Sample Evaluation
Record the sample ID, manual revision, electrical configuration and evaluation conditions. Compare results with agreed acceptance criteria; electrical output measurements require a defined method and suitable equipment. For the evaluation method, see LED and Microcurrent Scalp Comb Claims: What Buyers Should Verify.

Modes & Controls
- Match startup mode and LED indicators to the approved instructions
- Check all five output levels and mode-to-control mapping
- Check vibration switching and the reference 10-minute auto-off
Charging & Power
- Check charging indicators and full-charge behavior
- Match input ratings and accessories to the approved version
- Check operation after unplugging; the reviewed manual prohibits use while charging
Contact Teeth & Handling
- Inspect contact-tooth alignment, end finish and spring-back
- Review grip, assembly and contact under permitted conditions
- Measure sample dimensions and net weight, recording included parts
Reservoir & Liquid Compatibility
- Check reservoir fit, removal, dispensing and leakage
- Evaluate approved liquid for residue, blockage and material compatibility
- Check cleaning instructions, accessory completeness and pack-out
Private Label Options & Version Configuration
Define the sample version first. Review branding and packaging separately from changes to electrical output, controls, battery, contact teeth or reservoir structure that require engineering evaluation.

KD3802 Sourcing Questions
Answers for brands, importers and buyers evaluating the KD3802.
How do the LED modes and five output levels work?
The reference instructions associate red and blue LEDs with different operating modes and provide five output levels within the selected mode. Confirm the mode labels and permitted application for your version. The five levels are output controls, not five LED brightness settings; quantitative output claims need matched test records.
Which liquids can be used in the reservoir?
Use only a formulation approved for the selected version. The reviewed English manual excludes essential oils and powdered formulations. Evaluate dispensing, residue, blockage, seals and contact-material compatibility before including a liquid in the commercial product concept.
Is the device waterproof, and how should cleaning be evaluated?
The reviewed manual states that the device is not waterproof and must not be immersed or directly rinsed under a faucet. Follow the approved cleaning instructions, turn it off before cleaning and check residue removal without assuming that a removable reservoir makes the whole device washable.
What should buyers confirm before sample approval?
Confirm the sample version, controls, charging configuration, automatic shut-off, contact teeth, liquid compatibility and accessories. Measure dimensions and net weight, resolve conflicting records, and align the manual, rating label and packaging with the proposed order.
Is the KD3802 a heated hair-styling brush?
No. The KD3802 is a rechargeable scalp massage comb. It does not include heating, temperature settings, hair straightening or curling functions.
What private label options and documents can be reviewed?
Review logo placement, available finishes, packaging, labels, manual language and accessories. Electrical or structural changes require engineering evaluation. Request the specification, instructions and available version-matched safety or EMC records. Share the market, quantity and proposed scope so sample availability, cost and schedule can be confirmed.
