No.
The device description indicates a simple, pre-set operation without any mention of data processing, learning, or adaptive algorithms.
Yes
The device is indicated to "promote hair growth" for specific classifications of hair loss, which addresses a health-related condition.
No
Explanation: A diagnostic device is used to identify a condition or disease. This device is indicated to promote hair growth, which is a therapeutic rather than a diagnostic function.
No
The device is not a software-only medical device because the description explicitly states it consists of physical components such as 100 laser diodes, 200 red light diodes, a hair-growing cap, a device base, and a USB power cord, which are tangible hardware elements that emit light for therapeutic purposes. It does not mention any software as its primary function or deliverable.
No.
The device's intended use is to promote hair growth, not to diagnose a disease or condition using in vitro diagnostic methods. It is an over-the-counter therapeutic device.
N/A
Intended Use / Indications for Use
The CurrentBody Skin Dual Light Hair Growth Helmet is indicated to promote hair growth in males with who have Norwood-Hamilton classifications of IIa-V or females with who have Ludwig-Savin Classifications of I-II and both with Fitzpatrick Skin Phototypes I-IV.

Device Description
The CurrentBody Skin Dual Light Hair Growth Helmet (model:MZ-07A) is an over-the-counter device designed to promote hair growth in males who have Norwood-Hamilton Classifications of IIa-V patterns of hair loss and to promote hair growth in females who have Ludwig-Savin Classifications of I-II; both with Fitzpatrick Skin Types I-IV.
The device consists of 100 laser diodes with wavelength at 655±5nm, and 200 red light diodes with wavelength at 660±5nm.
The CurrentBody Skin Dual Light Hair Growth Helmet includes a hair-growing cap, a device base and a USB power cord. There are LEDs and lasers diodes inside the cap to emit visible red light, the device base acts as a support when the device is not used. There is a power button on cap to turn on/off the device, a digital display to show the remaining treatment time, an power indicator to show charging status and a USB port for charging.
The treatment parameter is pre-set by manufacturer, the device will auto off after treatment.

Regulation Name: Infrared Lamp
Regulatory Class: Class II
Product Code: OAP
Dated: March 31, 2025
Received: April 2, 2025
Dear Alain Dijkstra:
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 (the 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 available 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.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).
Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).
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 (reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-combination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.
All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-devices/medical-device-safety/medical-device-reporting-mdr-how-report-medical-device-problems.
For comprehensive regulatory information about medical devices and radiation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance) and CDRH Learn (https://www.fda.gov/training-and-continuing-education/cdrh-learn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic.
