TL;DR for buyers
- HT01 is best suited to brands that want a portable, demonstrable hair-and-scalp-care SKU—not a hands-free full-scalp device. Its handheld comb format supports section-by-section placement but requires the user to move it through the hair.
- The standard configuration combines 14 × nominal 655 nm vertical-cavity surface-emitting laser (VCSEL) Chips, 14 × 660 nm red LEDs and 14 × 460 nm blue LEDs In 14 tri-chip modules, plus three-level EMS, fixed vibration and a detachable serum applicator.
- Der 5 mW figure is optical output power per VCSEL chip. It is not irradiance, Fluenz, total scalp dose or a finished-device laser classification.
- Published research on other 655 nm laser-comb and helmet devices provides category context, but it does not establish HT01-specific clinical performance or justify copying another device’s protocol.
- Before approving a sample or marketing claim, request the exact configuration’s optical test conditions, finished-product laser classification, Etiketten, instructions and target-market documents.
What Is HT01—and What Is It Not?
HT01 is a handheld OEM/ODM hair-and-scalp-care platform that combines light, EMS, vibration and serum application in one device. Its current product page does not identify an HT01 510(k) number or publish HT01-specific clinical results, finished-device irradiance or a laser-classification report. Buyers should treat each item as unverified until the exact-model record or report is supplied.
That distinction matters because a buyer is making two decisions at once:
- Does the comb format and feature set fit the planned product line?
- Does the exact finished configuration and documentation support the target market and planned claims?
The first decision can be made from product specifications and sample handling. The second requires model-specific reports and regulatory review. A wavelength, a component data point or research on another device cannot close that gap.
Die jetzige HT01 product page positions the device for beauty, hair-wellness, scalp-care, distribution and private-label channels. This guide uses the market category phrase “laser hair growth comb” for sourcing context; it is not a claim that HT01 has an authorized hair-growth indication. In den Vereinigten Staaten, the FDA’s OAP record defines the laser, comb, hair category around promoting hair growth in androgenic alopecia. A product name, label or advertisement using that intended purpose therefore needs an exact-model regulatory pathway and claim review—not just a category keyword or supplier statement.
Does Published 655 nm Hair-Growth Research Prove HT01 Works?
NEIN. Published 655 nm research supports the broader device category, but it does not prove the performance of an untested exact model.
A 2021 systematic review and meta-analysis of home-use LLLT devices pooled seven double-blind randomized controlled trials and found greater hair-density improvement with the studied devices than with sham treatment. The review evaluated named home-use products selected by their U.S. FDA market status—not an interchangeable wavelength category—so the results remain tied to those studied configurations. It included both comb and helmet formats, but it also reported meaningful heterogeneity, short follow-up periods and no direct head-to-head comparison between devices.
A separate multicenter, randomisiert, sham-controlled study evaluated specific LaserComb models using 655 nm or combined 635/655 nm laser beams. It supports a narrower point: comb-format red-laser devices have been studied in people with pattern hair loss. It does not show that any product with a similar wavelength, diode rating or comb shape will reproduce those results. The paper reports that the manufacturer partially funded the study and supplied active/sham devices and equipment, including the digital imaging system. It also discloses honorarium, consulting or participation fees involving two authors and a grant to a university department for part of the study.
For a sourcing decision, use the research this way:
| Beweisschicht | What it can tell a buyer | What it cannot tell a buyer |
|---|---|---|
| Published category research | Some specific low-level red-light/laser devices and comb formats have human evidence | HT01 has the same efficacy, dose or safety profile |
| HT01 product specifications | What components, Wellenlängen, modes and user features are in the standard configuration | How much light reaches the scalp or what clinical result follows |
| HT01 finished-device reports | Bestrahlung, accessible emission, classification and tested configuration—if supplied | Automatic authorization for every market or marketing claim |
| Exact-model market authorization | What the named model, holder and intended use may support in that market | Other models, modified configurations or broader claims |
Buyer rule: similar wavelength is a reason to investigate a product, not a substitute for exact-device evidence.
What Does “5 mW per VCSEL Chip” Actually Mean?
It means the rated optical output power of one VCSEL emitter; it does not describe the exposure received by a square centimeter of scalp.
These four terms should stay separate in an RFQ and in consumer-facing copy:
| Metrisch | Was es bedeutet | HT01 status as currently documented |
|---|---|---|
| Optical output power (MW) | Light power emitted by an individual source or defined assembly | 5 mW pro VCSEL-Chip |
| Bestrahlung (MW/cm²) | Power arriving per unit area under a stated distance, mode and measurement method | Not provided |
| Radiant exposure / Fluenz (J/cm²) | Energy delivered per unit area over a stated exposure time | Cannot be calculated from the current information |
| Laser class | Finished-product hazard classification based on accessible emission and specified test conditions | Must be confirmed by a model-specific report and labeling review |
Do not relabel 5 mW as 5 mW/cm². Do not multiply 14 × 5 mW and call the result “scalp power” or “dose.” The sources operate within modules and modes, while beam geometry, Arbeitszyklus, Distanz, hair obstruction, movement and the measurement aperture affect what a test instrument—or the scalp—receives.
Laser classification is also a finished-product question. Der FDA’s laser safety overview explains that laser products are subject to class-based engineering controls and risk communication. IEC 60825-1 provides the equipment-classification framework for laser products. A component rating alone does not establish the HT01 product class.
For a U.S. project, laser-product radiation controls and medical-device clearance are separate checks. Die FDA radiation-emitting product market FAQ explains that applicable product reports must be submitted before U.S. commerce; an accession number confirms receipt but is not an approval. It also states that importers of products subject to an FDA performance standard submit Form FDA 2877 and may provide the accession number for a previously reported product. Unter Laser Notice 56, FDA states that it does not intend to enforce certain requirements in 21 CFR 1040.10 Und 1040.11 for manufacturers that certify to the relevant IEC 60825-1 Edition 3 und IEC 60601-2-22 Edition 3.1 provisions identified in the notice. None of these records substitutes for an applicable 510(k), und a 510(k) does not replace laser-product radiation controls.
What to request:
- the finished-device optical report and accessible-emission/classification report;
- whether 5 mW is measured at the emitter or after optics, including operating current, temperature and tolerance;
- the active mode, Instrument, Verfahren, aperture, emitter-to-measurement-plane distance and irradiance at a defined use plane such as the tooth-tip/contact plane when applicable;
- final labels, eye-exposure controls and warnings, user instructions and target-market reporting records for the quoted configuration.
What Do the Three HT01 Light Modes Add?
The three modes add configurable hardware and product-story options, but each channel needs its own evidence boundary.
The standard HT01 configuration uses 14 compact tri-chip modules, für 42 insgesamt lichtemittierende Chips:
| Modus | Active light sources | Defensible product description | Avoid without direct evidence |
|---|---|---|---|
| Modus 1 | 655 nm VCSEL + 660 nm rote LED | Combined VCSEL and red-LED mode | Clinically optimized combination; faster or deeper hair regrowth |
| Modus 2 | 660 nm rote LED | Red-LED scalp-care mode | Proven HT01 treatment dose or outcome |
| Modus 3 | 460 nm blaue LED | Blue-LED scalp-care mode | Antibakteriell, anti-dandruff, acne-treatment or hair-regrowth claims |
Der 655 nm value is the nominal VCSEL wavelength; the technical product specification states 655±5 nm. The red LED is 660 nm, and the blue LED is 460 nm. The three chip types are present in a 1:1:1 Verhältnis.
Blue light deserves particular restraint. A 2017 human hair-follicle laboratory study reported that 453 nm blue light at 3.2 J/cm² prolonged anagen in isolated follicles ex vivo. That is early mechanistic evidence—not a human clinical trial—and the wavelength, dose and exposure protocol are not an HT01 validation study. Until direct evidence exists, Die 460 nm mode should be described as a hardware option rather than a proven hair-growth or scalp-treatment function.
For the red and blue LED channels, an applicable photobiological-safety assessment may use IEC 62471, which covers incoherent sources including LEDs but excludes lasers. Buyers should confirm the applicable product standard, Ausgabe, tested modes, exposure conditions and exact model with the laboratory rather than treating a generic LED certificate as proof.
The same discipline applies to EMS, vibration and serum use. HT01 provides three EMS intensity levels with an independent off state, a stated 5–10 kHz frequency, a fixed-intensity vibration function and a detachable magnetic applicator. These are user-experience and product-bundling features. They should not be translated into improved absorption, circulation or hair-growth outcomes without direct testing. The frequency alone does not define electrical output: request whether it is a carrier or pulse-repetition frequency, along with waveform, voltage/current limits, electrode/contact configuration, risk assessment and the warnings and contraindications supported by the final design.
When Does a Comb Format Fit a Brand’s Product Line?
Choose a comb when portability, manual sectioning and a demonstrable routine matter more than hands-free full-scalp coverage.
Unlike a cap or helmet, a handheld comb does not fix the light sources over the entire scalp for the whole session. The user controls placement, speed, overlap and contact. That creates both a commercial advantage and an engineering question.
A comb is a practical fit when:
- the brand wants a compact SKU that is easier to display, demonstrate and ship than a helmet;
- the intended routine uses manual sectioning or attention to selected scalp areas;
- the product line already includes compatible scalp-care liquids or routines;
- einstellbares EMS, vibration and a tactile combing experience add meaningful differentiation;
- the brand can give clear movement, contact, cleaning and liquid-compatibility instructions.
A comb may be the wrong format when:
- the product concept depends on passive, freihändig, simultaneous full-scalp coverage;
- the brand needs a locked exposure geometry with minimal variation in user movement;
- the launch requires an existing exact-model clinical protocol or FDA clearance;
- the channel cannot support detailed instructions, warning labels or customer education;
- the planned serum or scalp liquid has not been checked for applicator compatibility and cleaning.
Brands still comparing form factors can use Wakelife’s cap-versus-helmet sourcing guide as a broader format reference. For HT01, the important addition is manual movement: a sample evaluation should test not only comfort but also whether users can follow a repeatable sectioning routine.
What Are the Current Standard HT01 Specifications?
The following values describe the current standard configuration; customized projects require a new configuration review.
| Spezifikation | HT01 standard configuration |
|---|---|
| Produkttyp | Handheld VCSEL laser hair and scalp care comb |
| Light modules | 14 × 3030 tri-chip modules |
| Total light-emitting chips | 42 |
| Light-source ratio | 14 VCSEL : 14 red LED : 14 blue LED (1:1:1) |
| Wellenlängen | 655±5 nm VCSEL + 660 nm rote LED + 460 nm blaue LED |
| VCSEL optical output | 5 mW pro VCSEL-Chip |
| Light intensity | Behoben |
| Lichtmodi | VCSEL + red LED; red LED; blue LED |
| EMS | Aus + three adjustable levels; 5–10 kHz |
| Vibration | Feste Intensität |
| Comb teeth | Flexible conductive silicone |
| Serum applicator | Abnehmbares magnetisches Design |
| Timer | 10 minutes with automatic shutoff |
| Indicators | LED indicators; kein Bildschirm |
| Batterie | 1300 Mah |
| Operating time | ≥60 Minuten |
| Ladezeit | ≤2,5 Stunden |
| Product dimensions | L249,8 × B63,44 × T27,45 mm; ±0.5 mm tolerance |
This table is a purchasing baseline, not a clinical protocol. In particular, the 10-minute timer tells the buyer how the current control logic works; it does not by itself establish an evidence-based treatment frequency or dose. Sample availability and MOQ remain commercial terms that depend on the project scope rather than technical specifications.
What Should Buyers Verify Before Approving an HT01 Sample?
Approve the sample only after the physical unit, specification revision, optical/safety records and planned claims all refer to the same configuration.
Use this matrix during supplier review:
| Verification item | Ask for | A satisfactory answer should show | Rote Fahne |
|---|---|---|---|
| Konfigurationskontrolle | Dated specification, BOM/configuration identifier and module datasheet or drawing | The sample and quotation use the same module count, package architecture, Wellenlängen, modes and controller logic | Sales sheet and sample describe different EMS levels or wavelengths |
| Optical output | Report with instrument, Verfahren, active mode, measurement plane/distance, operating conditions and tolerance | Per-source output at the stated location is separated from finished-device irradiance at a defined use plane | A single `5 mW` value is presented as dose or mW/cm² |
| Optical distribution | Spatial irradiance map or module-to-module variation at a defined use plane and active mode | Coverage variation and acceptance tolerance are visible instead of being reduced to one peak reading | Only the highest point or one emitter is reported for the 14-module assembly |
| Thermal and control behavior | Temperature-rise record for teeth/contact areas and housing in the worst-case active mode over the full 10-minute cycle, plus timer/auto-shutoff, repeated-operation and charging checks | Test conditions, locations, limits and pass/fail criteria match the final sample | Surface temperature or control behavior is assumed from component data |
| Laser safety | Finished-device classification report, engineering controls, eye-exposure warnings, labels and applicable market records | Exact model/configuration and applicable laser sources and use conditions are within scope | A component datasheet or another product’s report is offered instead |
| LED photobiological safety | Applicable assessment, such as IEC 62471 where appropriate, und getestete Konfiguration | Red and blue channels, operating modes and exposure conditions are identifiable | A generic LED certificate with no model/configuration scope |
| EMS output | Waveform, voltage/current limits, frequency definition, contact design and risk documentation | All three levels and the off state match the final controller and manual | `5–10 kHz` is the only electrical-output information provided |
| Instructions | Current user manual, risk-based warnings, contraindications and cleaning/liquid restrictions | Movement, contact, Timer, EMS, Aufladen, warnings and maintenance are consistent | Marketing promises exceed the instructions or foreseeable misuse is omitted |
| Market and claims | Exact records or a written regulatory plan for the target country | Modell, Halter, Verwendungszweck, geplante Ansprüche, radiation-product duties and private-label relationship align | Anmeldung, an accession number or a factory certificate is used as product clearance |
| Liquid and enclosure | Materials, liquid-compatibility evidence, cleaning method and any claimed ingress-protection rating | Applicator, teeth, housing and charging areas are assessed for the intended liquids and cleaning | “Use with serum” is claimed without compatibility or ingress review |
| Customization impact | Change-control and revalidation plan | Color/packaging changes are separated from wavelength, Kontrolle, structural and safety changes | Deep technical changes are promised with no testing or document impact |
In den Vereinigten Staaten, the FDA’s generic classification database includes a laser, comb, hair category under product code OAP. The record associates the category with 21 CFR 890.5500, a required radiation-safety product report and the laser standards in 21 CFR 1040.10 Und 1040.11. It is a useful search route, but it is not evidence that HT01 has a 510(k) or that an HT01 radiation product report has been filed. The FDA also warns that establishment registration and device listing do not mean approval, clearance or authorization. Ask for each exact record and verify the model, reporting manufacturer, Halter, intended use and labeling scope yourself.
What Should Go Into an HT01 RFQ?
A useful RFQ defines the market, claims and configuration before asking for price. Copy this checklist into the inquiry:
- Target countries and planned sales channels.
- Intended positioning: beauty/scalp care, hair wellness or a regulated hair-growth claim.
- Required sample configuration and revision identifier.
- Standard or customized wavelengths, module/package architecture, modes and controller logic.
- Finished-device optical data, including output location, Betriebsbedingungen, Toleranz, measurement plane/distance, active mode and a spatial map or module-variation result.
- EMS waveform, voltage/current limits, carrier versus pulse-repetition frequency and contact design.
- Laser-classification, eye-exposure controls/warnings, LED photobiological-safety, EMC, Batterie, elektrische Sicherheit, thermal, timer/auto-shutoff, Aufladen, label and manual documents required for review.
- Für die USA. projects, applicable laser product report/accession, certification and identification labels, annual-report status, FDA 2877 responsibility and any separate 510(k) Weg.
- Planned liquids or serum bundle, including material compatibility, cleaning method and ingress-protection evidence.
- Charging interface/input, product weight, housing and tooth materials, warranty and replacement-accessory requirements.
- Logo, Farbe, Verpackung, Sprache, Barcode, Zubehör, sample quantity, forecast volume and delivery market.
- Which changes require new validation, supplemental reporting, tooling or regulatory review.
The answers should determine whether the project is neutral stock, Handelsmarktlabel, light OEM or deeper ODM. They should also determine which documents can remain valid and which must be updated after customization.
Final Buyer Decision
HT01 is a credible candidate when the commercial objective is a compact, multi-function scalp-care device and the brand is prepared to validate the final configuration before making performance or regulatory claims. Its strongest current differentiation is tangible: a tri-chip 655/660/460 nm light architecture, three selectable light modes, three-level EMS, flexible conductive teeth, vibration and a detachable applicator.
It is not the right shortcut for a project that needs ready-made HT01 clinical evidence, a transferable protocol or an assumed FDA clearance. Those are exact-device questions, not benefits that arrive automatically with a wavelength or component.
To evaluate the standard configuration, visit the HT01 product page or review Wakelife’s broader laser and LED hair-growth device range. When requesting a quote, include the target market, geplante Ansprüche, channel and customization scope so the sample and document review start from the same brief.
Häufig gestellte Fragen
Tut 5 mW mean HT01 irradiance is 5 MW/cm²?
NEIN. Der 5 mW specification is optical output power per VCSEL chip. Irradiance requires a unit-area measurement under stated geometry and operating conditions.
Ist HT01 von der FDA zugelassen??
No HT01 510(k) number is identified on the current product page. Treat any future clearance claim as unverified until the exact model, Halter, intended use and labeling are matched in FDA’s public database; factory registration, an accession number or another model’s clearance is not a substitute.
If a U.S. launch avoids hair-growth claims, do laser-product obligations disappear?
NEIN. FDA electronic-product radiation controls are a separate layer from medical-device claim and 510(k) Rezension. The applicable product-reporting, certification/identification labeling, performance-standard and import duties still need to be determined for the exact laser product; avoiding a medical claim does not by itself waive them.
Can a brand claim that the 460 nm mode grows hair?
Not from the evidence reviewed here. The closest relevant study used 453 nm blue light in isolated human hair follicles ex vivo, not an HT01 human clinical trial.
Can the wavelengths or EMS settings be customized?
They may be evaluated as an OEM/ODM project, but technical changes can alter optical performance, Sicherheitsprüfung, labeling and regulatory requirements. Confirm feasibility and the revalidation plan before approving the final specification.
