Laser Device

Offered in the market many laser devices to stimulate hair growth. Hairmax laser comb is the only laser that has scientific studies showing effectiveness in patients who have used it.
It is the first and only laser device FDA approved light in united states promoting hair growth in both men and women.

The laser works by producing light with a specific wavelength that goes directly to the hair follicle. This light is picked up by the cells that produce hair and transform it into energy for your benefit.

This results in that the hair thickness and quality improvement. 3 weekly sessions of 15 minutes duration are needed. Changes are noted between the 6-12 week.

The laser emits a low intensity light source that provides additional energy to the hair follicle. Laser light therapy stimulates cell production of growth factors that will come in and keep the majority of hair follicles in the anagen or growth phase.

The manufacturer recommends sessions 10-15 minutes should be done 3 times per week on nonconsecutive days and the results can be seen from the 4th month.

It is essential to continue treatment as if for the recovered volume will be lost. The treatment is safe and effective and has no contraindications.


Our Recommendation
Excited by the FDA certification, by the theory of how it works and to the results seen in some patients we decided to investigate a little more before recommending or censure, especially also by the presence of a significant number of unhappy people.

Below is the original text approved by the FDA for use in the treatment of androgenetic alopecia in men and women.

HairDoctors conclude, is that the results are poor but something real and require prolonged treatment, so if you have the patience, resources and time to this type of treatment, worth a try, but use treatments more effectively drugs as described above.

Device Description:

HairMax is a hand-held low-level laser device that emits laser light with the intention to promote hair growth. -The device provides distributed laser light to the scalp while the comb teeth simultaneously part the user’s hair to ensure maximum laser light reaches the user’s scalp. HairMax Dual 12 utilizes twelve laser modules, six with wavelengths of 655nm and six with wavelengths of 635n with the same exact output power as the HairMax Pro 12.

Intended Use:

The HairMax Dual 12 is indicated to Treat Androgenetic Alopecia and Promote Hair Growth in Females who have Ludwig (Savin) Scale 1-4, 11-1, H1-2, or frontal and Fitzpatrick Skin Types to IV.
Technological Characteristics:

The HairMax Dual 12 consists of a band-held low-level laser device that promotes hair growth. The device provides distributed laser light to the scalp while the device’s comb teeth simultaneously part the user’s hair to ensure maximum laser light reaches the user’s scalp. When in use, the device emits a beep and vibration every four seconds to notify the user to move the device to a new section of the scalp.

Performance Testing:

Testing to IfiC 60601-1 and 60601-1-2 confirm the device’s adherence to LVD,
electrical and EMC safety requirements.

Clinical Testing:

randomized, double-blind, controlled, multi-center clinical trial was conducted at sites, Cleveland Clinic - Wilma Bergfeld M.D., University of Minnesota - Maria

Hordinsky M.D. and University of Miami - Lawrence Schachner M.D. Each site complied with Institutional Review Board approval and oversight and in accordance with applicable references defined by the Food and Drug Cosmetics Act and Title 21, Code of Federal Regulations.

The clinical trials were listed on

The purpose of the clinical trial was to confirm the performance of the HairMax Dual 12 to treat androgenetic alopecia and promote hair growth in females who have
Ludwig (Savin) Scale 1-4, 11- 1, H-2, or frontal and Fitzpatrick Skin Types to IV.

After 16 weeks of treatment, 81% of the subjects using the HairMax Dual 12 experienced increases in hair count, (based on a minimum of new hairs being observed at follow up). Benefits continued to improve after 26 weeks of treatment, 95% of the subjects using the HairMax Dual 12 experienced significant increases in hair count (based on a minimum of new hairs being observed at follow up).

No subjects experienced any serious adverse event from the treatments.

The study population included females between the ages of 25 to 60 years with a diagnosis of androgenetic alopecia who had been experiencing active hair loss within the last 12 months. They were also required to have a Ludwig (Savin) classification of 1-4 or Frontal, and have Skin Type I, II, IIIor IV on the Fitzpatrick Skin Type Scale. Skin types were limited to the Fitzpatrick Skin types I-IV to facilitate the hair counting process, as it is difficult to count hairs on darker skin tones,

Substantial Equivalence

The HairMax Dual 12 is identical in technological characteristics as the HairMax Pro 12 as cleared in K103368 and HairMax Lux for females (KL 10233), except for the dual wavelength component. The HairMax Pro 12 contains twelve 655nm laser modules, the HairMax Dual 12 contains six 655nm laser modules and six 635nm laser modules.

All other technical aspects, including its power output, its comb component, its instructions for use and its audible or vibrating timer remain identical. The modification to the HairMax Dual 12 does not change the intended use of the product nor does it affect the products fundamental scientific technology. Therefore this change does not raise new questions of safety or effectiveness.

This was also demonstrated in a randomized, double-blind, control clinical study evaluating changes in terminal hair-count in the evaluation zone, as well as usability studies to validate instructions for use, confirm that device modifications do not affect the safe and effective use of the devices when compared to the predicates.

For those reasons, HairMax Dual 12 satisfies FDA’s substantial equivalence with respect to both the intended use and technological characteristics.
