Landmark HairMax LaserComb Clinical Study Results Published, Proving Efficacy and Safety In Treating Hair Loss

The results of 4 clinical studies conclusively proving the efficacy and safety of the HairMax LaserComb was published in a peer review medical journal in April 2014 and here is a summation of the article.

"The results of four clinical studies on the treatment of male and female pattern hair loss with the HairMax LaserComb, was just published today in a peer-review journal, The American Journal of Clinical Dermatology. The article, Efficacy and Safety of a Low-level Laser Device in the Treatment of Male and Female Pattern Hair Loss: A Multicenter, Randomized, Sham Device-controlled, Double-blind Study was co-authored by renowned experts in the field of hair disorders. The results of these studies have now provided robust and conclusive evidence that the HairMax LaserComb is both effective and safe for the treatment of pattern hair loss in men and women.

This is the link to the clinical article:

The four clinical studies were conducted under strict Good Clinical Practice Guidelines at multiple study sites, including major teaching institutions of dermatology such as the Cleveland Clinic, University of Minnesota and University of Miami. Enrolled in the study were 225 males and females diagnosed with androgenetic alopecia (male and female pattern hair loss). Subjects received either the HairMax LaserComb or a sham (inactive) device in a randomized, blinded manner so that no one knew which device they were on. The primary efficacy analysis was based on the change in hair count after 26 weeks treatment with the HairMax LaserComb, compared to change in hair count with the sham (inactive) device.

The results of the studies showed that there was an average increase in terminal hair count of over 20 hairs per cm² (equivalent to over 139 hairs per square inch). Additionally, a higher percentage of lasercomb-treated subjects reported overall improvement in hair loss condition and thickness and fullness of hair in self-assessment, compared with sham-treated subjects. No serious adverse events were reported in any subject receiving the lasercomb in any of the studies.

The authors concluded that: “Our results suggest that low-level laser treatment may be an effective option to treat pattern hair loss in men and women”. They also concluded that “Low Level Laser Therapy [LLLT] may provide a promising treatment option for patients who do not respond to either finasteride or minoxidil, and who do not want to undergo hair transplantation.”

The authors also had this overall observation: “…… while topical minoxidil solution or foam is widely used to treat pattern hair loss and is generally well tolerated, the treatment needs to be applied one or twice daily, and be in contact with the scalp for at least 4 hours. Such application can be impractical for many users, leading to noncompliance and reduced efficacy. As an alternative, the lasercomb treatment is safe and easy to apply, with 8-15 minutes of treatment three times per week, and leaves no residue on the scalp. Such user friendliness of the lasercomb may lead to better patient compliance and improved efficacy.”

Dr. Lawrence Schachner, Chairman of the Department of Dermatology at the Miller School of Medicine of the University of Miami, and senior author of the article said: “The results of these clinical studies provide further evidence that the HairMax LaserComb may be utilized as an effective option for treating androgenetic alopecia in men and women.”

  • How many Laser Diodes in HairMax LaserComb

    Hello HairMax/Lexington,

    I have two questions:

    1. How many Laser diodes are used in the HairMax LaserComb ?

    2. What type of Laser diodes, and at what wavelength ?

    Re: How many Laser Diodes in HairMax LaserComb

    Thanks for your posting.

    We use one strong diode that we manufacture into a Laser Module encompassing specialized optics and we beam split it into 8 beams using our proprietary and patented splitting device.

    The wavelength is in the red spectrum.

    Hope that helps.

      Hello Lexington International,

      thank you for replying back, and for partially ansewing my question regarding the type and wavelength of the single laser diode that is used in the HairMax LaserComb.

      The reason I am asking this question is quite simple. I like to know exactly what I am doing to my body with any type of product before I use it.

      The type of answer I would be looking for from any manufacture of a Low Level Laser Therapy product, that produces as a result of use "biostimulation", would be as follows.

      Type of Laser diode ? GaAs or GaAlAs or most likely InGaAlP .

      Wavelength of Laser diode ? 635 nm or 660 nm or maybe 670 nm .

      I am still interested in finding this information out because the HairMax LaserComb seems like it might be a good product. But it is nice to know what type of product your using before you apply it to your body.

      There is quite a bit of information available regarding Low level laser therapy for those of you who are interested. A good place to start would be the following WEB page,

      Thanks in advance,

        Thanks for your posting.

        We can tell you that the diode is a constant @ 660nM. All other specs are confidential.

        Yes we agree that is a great LLLT Portal. Just keep in mind that most of the research presented is from much higher-powered lasers.

        From our information there are 2 maybe 3 companies in the world producing LLLT devices for healthy hair growth. Us and Our CEO was a pioneer in the use of lasers for hair since the late 80’s in Sydney Australia. After years of trial and error we believe we have found the perfect formula for healthy hair growth.

        If you would like any additional information or details please let us know or call 561 417 0200.

          Hello David,

          Thank you for replying back, and for giving me a little more insight into the HairMax LaserComb. This type of information can help reassure some that might be hesitant to try the LaserComb by giving them some specifications to research on their own.

          I am still somewhat concerned about the amount, or the dosage of irradiance which is entering the tissue, and what its greatest active depth is, since the LaserComb is to be used in very close proximity to ones brain.

          I have purchased a HairMax LaserComb and should receive it tomorrow. I am hoping for some really positive results regarding improved hair condition and growth. Hopefully the LaserCombs ability to biostimulate and icrease the circulation will over the prescribed time have some great results.

          Thanks again David,

            Thanks for your posting and order.

            Re;I am still somewhat concerned about the amount, or the dosage of irradiance which is entering the tissue, and what its greatest active depth is, since the LaserComb is to be used in very close proximity to ones brain.

            There is no reason for concern. The Laser penetrates only soft tissue on the outer dermis and only as deep as your follicles. That is also one of the reasons why a higher powered laser would not provide better results.

            I copy the following lines are for your reference. The complete overview can be found on

            "The name LASER is short for Light Amplification by Stimulated Emission of Radiation. Laser light and devices are sometimes referred to as laser emitting, laser producing, laser radiation, etc. This terminology is confusing. There is NO radiation in the sense we normally refer to as radiation, lasers produce light high in energy, nothing else (even sunlight is a type of radiation). No radioactivity or dangerous energy is produced. Radiation with laser Hair Care does not influence to the general heating of tissue; the laser light is used as a ‘cold light’.

            Yes! Laser Hair Care is a non-surgical therapeutic laser. It is the most powerful laser that is safe for cosmetic purposes and fully complies with international laser safety standards. Laser Hair Care is approved for cosmetic use in the EEC and US as a Certified Class 3A laser by the Food and Drug Administration, which has the most rigid standards in the world and fully complies with Radiation Control for Health and Safety act. The energy produced by the photons does not have the thermal component that can cause injuries to users or operators. Laser light energy does not alter molecular structures, it stimulates the body’s mechanism to repair and heal itself.
