The HairMax LaserComb 41 is indicated to treat Androgenetic alopecia and promote hair growth in males who have Norwood Hamilton Classifications of IIa to V patterns of hair loss and treat Androgenetic alopecia and, promote hair growth in females who have Ludwig (Savin) Scale I-4, II-1, II-2, or frontal, both with Fitzpatrick Skin Types I to IV. The HairMax LaserComb 82 is indicated to treat Androgenetic alopecia and promote hair growth in males who have Norwood Hamilton Classifications of IIa to V patterns of hair loss and treat Androgenetic alopecia and, promote hair growth in females who have Ludwig (Savin) Scale I-4, II-1, II-2, or frontal, both with Fitzpatrick Skin Types I to IV.

Device Description

The HairMax LaserComb 41 (HMLC 41) and HairMax LaserComb 82 (HMLC 82) are low-level laser devices that provide distributed laser light to the scalp while comb teeth simultaneously part the user's hair to ensure the laser light reaches the user's scalp. The HMLC 82 device emits 82 laser beams with wavelengths of 655 nm (+/- 10 nm), spaced at 7mm intervals and has a total laser module output within the limitation of a Class 3R laser. The HMLC 41 device emits 41 laser beams with wavelengths of 655 mm (+/- 10 nm), spaced at 7mm intervals and has a total laser module output within the limitation of a Class 3R laser. The laser diode modules used in the HMLC 41 & 82 are identical to those used in their predicate devices. As with the predicate device, the HMLC 41 & 82's lasers are contained in between hair parting teeth that push the hair aside, allowing the optimum amount of laser energy to reach the scalp, as the user passes over the scalp. The hair parting teeth move the hair aside and allow an unobstructed path of laser energy to the scalp. At the beginning of a treatment session, the device is placed in the first position on the scalp (the first 7.5cm scalp section, closest to the forehead) and will rest here for the intended treatment time. As with the predicate devices, the HMLC 41 & 82 will use a short vibration to advise the user it is time to move to the next scalp location. The HMLC 41 & 82 will maintain contact with the scalp allowing the hair parting teeth to part the hair as the user moves the device backwards, combing the hair, along the scalp to the second position. The teeth are necessary to part the hair and provide an unobstructed path for the laser light to reach the scalp. The device will remain in the second position until the vibration informs the user to move to the third position. Similar indication and movement will continue for three positions to cover the entire area of hair loss on the scalp. The lasers will automatically turn off after the intended treatment duration. The units operate from an internal, rechargeable lithium polymer battery. The LiPoly battery is charged from a Class 2, UL, and CUL rated wall transformer at 6VDC and 1000mA. In the event of a power failure, the laser control circuitry is designed to disable the laser diodes until reactivated by the control switch. The devices include battery monitoring and charging circuitry which ensure the effective delivery of optimal laser energy output during the treatment time. The devices include a proximity sensor and will not allow the lasers to be turned on unless in contact with the scalp.

6. Device Description

The HairMax LaserComb 41 (HMLC 41) and HairMax LaserComb 82 (HMLC 82) are low-level laser devices that provide distributed laser light to the scalp while comb teeth simultaneously part the user's hair to ensure the laser light reaches the user's scalp. The HMLC 82 device emits 82 laser beams with wavelengths of 655 nm (+/- 10 nm), spaced at 7mm intervals and has a total laser module output within the limitation of a Class 3R laser. The HMLC 41 device emits 41 laser beams with wavelengths of 655 mm (+/- 10 nm), spaced at 7mm intervals and has a total laser module output within the limitation of a Class 3R laser. The laser diode modules used in the HMLC 41 & 82 are identical to those used in their predicate devices.

As with the predicate device, the HMLC 41 & 82's lasers are contained in between hair parting teeth that push the hair aside, allowing the optimum amount of laser energy to reach the scalp, as the user passes over the scalp. The hair parting teeth move the hair aside and allow an unobstructed path of laser energy to the scalp.

At the beginning of a treatment session, the device is placed in the first position on the scalp (the first 7.5cm scalp section, closest to the forehead) and will rest here for the intended treatment time. As with the predicate devices, the HMLC 41 & 82 will use a short vibration to advise the user it is time to move to the next scalp location. The HMLC 41 & 82 will maintain contact with the scalp allowing the hair parting teeth to part the hair as the user moves the device backwards, combing the hair, along the scalp to the second position. The teeth are necessary to part the hair and provide an unobstructed path for the laser light to reach the scalp. The device will remain in the second position until the vibration informs the user to move to the third position. Similar indication and movement will continue for three positions to cover the entire area of hair loss on the scalp. The lasers will automatically turn off after the intended treatment duration.

The units operate from an internal, rechargeable lithium polymer battery. The LiPoly battery is charged from a Class 2, UL, and CUL rated wall transformer at 6VDC and 1000mA. In the event of a power failure, the laser control circuitry is designed to disable the laser diodes until reactivated by the control switch. The devices include battery monitoring and charging circuitry which ensure the effective delivery of optimal laser energy output during the treatment time. The devices include a proximity sensor and will not allow the lasers to be turned on unless in contact with the scalp.

• 7. Intended Use
     The intended use of the HairMax LaserComb 41 and HairMax LaserComb 82 is the same as for the HairMax LaserComb Lux 9 (HMLC Lux 9) cleared pursuant to K103368 and K110233.

The HairMax LaserComb 41 is indicated to treat Androgenetic alopecia and promote hair growth in males who have Norwood Hamilton Classifications of IIa to V patterns of hair loss and treat Androgenetic alopecia and, promote hair growth in females who have Ludwig (Savin) Scale I-4, II-1, II-2, or frontal, both with Fitzpatrick Skin Types I to IV.

The HairMax LaserComb 82 is indicated to treat Androgenetic alopecia and promote hair growth in males who have Norwood Hamilton Classifications of IIa to V patterns of hair loss and treat Androgenetic alopecia and, promote hair growth in females who have Ludwig (Savin) Scale I-4, II-1, II-2, or frontal, both with Fitzpatrick Skin Types I to IV.

• 8. Technological Characteristics
     The HMLC 41 & 82 are versions of Lexington's previously cleared HMLC Lux 9 that has been modified as a result of customer feedback to provide hands-free operation for ease of use. To address this issue and reduce the overall effort required by users, Lexington sought to: 1) modify the shape of the device such that it can rest on the scalp (without the need for the user to hold it in place with their hand) while maintaining the device's hair-parting teeth feature; and 2) reduce treatment time by increasing the number of lasers providing treatment over a larger surface area while maintaining dosage rate. The implemented modifications included changes to:

• Device configuration/dimensions to accommodate additional lasers and allow "handsfree" placement on the scalp;

• Addition of a second identical battery

• Conforming software changes reflecting reduced overall treatment time; and

• . Addition of a proximity sensor for laser activation.

Otherwise, the modified devices have the same technological characteristics as their predicate to include operating principle, fundamental scientific technology, design, materials, and chemical composition.
