Yes
The device is indicated to treat a medical condition (Androgenetic Alopecia) and promote hair growth, which are therapeutic claims.

No.

The device is indicated to treat Androgenetic Alopecia and promote hair growth, not to diagnose a condition.

No

The device description clearly states it is a "comb-shaped device that emits led light" and includes physical components like a main unit, charging dock, power cable, and a built-in rechargeable battery. This indicates it is a hardware device with embedded software, not a software-only medical device.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
  • Device Function: The Hair Growth Comb is a device that applies light therapy directly to the scalp to promote hair growth. It does not analyze any biological samples.
  • Intended Use: The intended use clearly states it's for treating Androgenetic Alopecia and promoting hair growth, which is a therapeutic application, not a diagnostic one.
  • Device Description: The description focuses on the physical design and how it delivers light to the scalp. There is no mention of sample collection or analysis.

Therefore, based on the provided information, the Hair Growth Comb is a therapeutic device, not an In Vitro Diagnostic device.
