Indications for Use

The Hair Growth Device is indicated to promote hair growth in males with androgenetic alopecia who have Hamilton-Norwood Classifications of Ila-V and females with androgenetic alopecia who have Ludwig-Savin Classifications of I-II and Fitzpatrick Classification of Skin Phototypes I to IV.

Device Story

Hair Growth Device LS-D601 is an OTC helmet-based system for home use. It utilizes 26 laser diodes (650-660nm) and 30 red light LEDs (640-660nm) to deliver low-level light therapy to the scalp. The device features an integrated sensor system that automatically pauses therapy if the user's head moves outside the radiation zone and resumes when the correct position is re-established. An audible beep pattern signals the end of the 25-minute treatment cycle. The device is powered by an external adapter. It is intended to promote hair growth in patients with androgenetic alopecia. Users operate the device independently at home; the system provides feedback on treatment completion via audio cues.

Clinical Evidence

Bench testing only. Includes biocompatibility (ISO 10993-1, -5, -10), electrical safety (ANSI AAMI ES60601-1), electromagnetic compatibility (IEC 60601-1-2), and laser safety (IEC 60825-1). A usability study with 15 participants confirmed that users could understand labeling and operate the device safely and effectively.

Technological Characteristics

Helmet-based device with 26 laser diodes (650-660nm, <5mW) and 30 red light LEDs (640-660nm). Powered by external adapter. Biocompatible materials per ISO 10993. Complies with IEC 60601-1, 60601-1-2, 60601-1-11, 60601-2-57, and IEC 60825-1. Standalone operation.

Indications for Use

Dear Jinghua Zhou:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

{1}------------------------------------------------

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

### 5. Device Description

{4}------------------------------------------------

### K210169

### Dongguan Lescolton Intelligent Electrical Appliance Co., Ltd.

The Hair Growth Device LS-D601 is composed of 26 3R class laser diodes (wavelength: 650-660nm, power<5mW) and 30 red light diodes (wavelength: 640nm-660mm) configured within an outer helmet and protective inner liner.

The use of diode lasers and non-laser LEDs provides for a full coverage of the upper 1/3 of the head; i.e., the area commonly covered with stylized hair. The helmet system will automatically pause to therapy if the subject's head is moved outside of the zone of radiation and will resume therapy when the correct head position is re-established. At the end of the therapy cycle, the system signals that therapy is complete and ready to be powered down, by emitting an audible beep pattern.

#### 6. Intended Use of Device

The Hair Growth Device is indicated to promote hair growth in males with androgenetic alopecia who have Hamilton-Norwood Classifications of Ila-V and females with androgenetic alopecia who have Ludwig-Savin Classifications of I-II and Fitzpatrick Classification of Skin Phototypes I to IV.
