No. The term "intelligent LLLT technology" is used, but the document does not provide details of any AI, machine learning, or deep learning models, nor does it describe any associated training or test sets that would typically be required for an AI model. The device description explicitly states "no communication function," further suggesting a lack of complex processing that would involve an AI model.
Yes.
The device is intended to treat a medical condition (Androgenetic Alopecia/Hair Loss) and promote a physiological change (hair growth), which are characteristics of a therapeutic device.
No
The device is intended to treat androgenetic alopecia and promote hair growth, not to diagnose a condition.
No
The device description explicitly states "The product is composed of main unit, USB cable, and silicone pad. The main unit consists of laser diodes that are spread throughout the helmet." and "Hair Growth Device is a small over-the-counter, portable, noninvasive, low-level laser device". This confirms the device is a physical hardware product that delivers laser therapy, not a software-only medical device. While it mentions "Software validation" in the performance studies, this refers to software embedded within the hardware, not a standalone software product.
No.
Reasoning: The device is a "Hair Growth Device" that uses low-energy laser therapy to promote hair growth in individuals with androgenetic alopecia. It is a physical therapy device that acts directly on the body (scalp and hair follicles) and does not involve the in vitro examination of specimens derived from the human body.

Note 1:
Although the "Amounts of Laser Lamp", "Treatment Time", "Treatment Area", "Irradiance", and "Fluence" of subject device and predicate device are a little difference, the energy and power parameters' range of subject device can be covered by predicate device's several models' range; they are very similar. So these parameters' differences will not raise any safety or effectiveness issue.
Note 2:
The Dimensions and Weigh of subject device, predicate devices and reference devices are difference, but they belong to portable device, only the size, weight and service life are difference, they are both complied with IEC 60601-1, so the differences do not affect the safety and effectiveness.
Note 3:
The "Operating environment" and "Transportation & Storage environment" of subject devices may be differ from the predicate devices and reference devices, but they are both compliance with the IEC 60601-1 and IEC 60601-1-11 standards, so the difference will not raise any safety or effectiveness issue.
Note 4:
They are both complied with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-11 and ISO 10993-1. IEC 60601-2-57 is for non-laser light source equipment, so the difference will not raise any safety or effectiveness issue.
Conclusions:
The subject device Hair Growth Device (Model: KCA441-200, KCA441-120, KCA441-88, KCA441-56, KCA441-200S, KCA441-120S, KCA441-88S, KCA441-56S, KCA451-200, KCA451-120, KCA451-88, KCA451-56, KCA451-200S, KCA451-120S, KCA451-88S, KCA451-56S) has been compared with iHelmet Hair Growth System (K162782), DermaScalp Laser Caps (K173846) and REVIAN RED (K173729). The subject device has same intended use, similar technological characteristics as that of predicate devices and reference devices. Although there are several specifications that are different between the subject device, predicate devices and reference devices, the comparison analysis has been completed to demonstrate that the differences between these parameters would not adversely impact the safety and effectiveness of the subject device. The subject device has undergone safety and performance tests, and the results complied with the test requests. Therefore, the differences between the subject device, the predicate devices and reference devices do not raise any concerns with respect to substantial equivalence. The subject device is substantially equivalent to the predicate devices.
