Your Hair Is A Part
Of What Defines You.

Learning that you are losing your hair can be devastating to hear.

To treat your alopecia, or hair loss, you need to know why hair loss occurs.

What is DHT, and how is it made?

Like many things in your body – it's complicated.

An enzyme called 5α reductase is where DHT’s journey begins. This enzyme is in your hair follicles and takes testosterone within the bloodstream and uses it to create more sebum, or an oil that helps moisturize your scalp. In that process however, DHT is created as a byproduct.

DHT has been found to play an important role during puberty. Especially for men, it’s the main driver behind their sexual development and parts of their overall health.

In the case of hair, DHT plays a role in the growth of body, pubic, and facial hair. However, once puberty is over, DHT is still being developed. For those experiencing androgenetic alopecia, they tend to be more susceptible to DHT attaching to your hair follicle causing miniaturization.

So, How Do I End Up Losing My Hair?

For the case of androgenetic alopecia, DHT attaches itself to the hair follicle, and over time restricts the amount of nutrients the hair follicle can obtain. This causes the hair follicle to shrink in a process called miniaturization. How much hair you lose due to miniaturization is due to genetics. Some people are more sensitive to the effects of miniaturization – like those who have androgenetic alopecia.

Medications that treat hair loss, like finasteride, are DHT blockers. This helps to reduce miniaturization.

For other forms of alopecia, like alopecia areata, are caused by an immune response to hair follicles, or telogen effluvium where hair loss can potentially come from high levels of stress.

Note that some hair loss is normal! Your head naturally sheds hair, but excessive hair loss is something that you should act on.

If you start to feel as if you’re losing more hair than you should, we recommend speaking with a hair care professional or physician as soon as possible. Catching and treating your hair loss early can help you save your hair before it’s too late.

We’re Serious About Facts.

Are there clinical trials that support the efficacy of Capillus?

Yes. Capillus Laser devices only use clinically proven technology. In fact, the premiere laser therapy cap model from Capillus - the CapillusPro model - has been proven effective through an independently reviewed clinical trial for which results have been published in an esteemed medical journal, Dermatologic Surgery. Dermatologic Surgery is a monthly peer-reviewed journal published by American Society for Dermatologic Surgery that deals with the subject matter of dermatology.

The CapillusPro device has been clinically proven in a double-blind clinical study registered on and managed by a neutral third party.* Clinical trial data indicated that low-level laser treatment of the scalp for 17 weeks with the CapillusPro device significantly improved hair counts by 51% in study participants who used the active (non-placebo) device. Subjects were able to use the device on a self-treatment, home-use basis. No side-effects of any kind were reported from clinical trial participants. The CapillusPro was proven to be a safe and effective treatment for androgenic alopecia within the appropriate stages of hair loss and skin tones as per FDA clearance.

Please note that the results mentioned above are specifically for the CapillusPro model. There have been no clinical trials to date on the other Capillus models to be able to assert an exact percent of average increase of hair.

There have also been many other clinical trials that support the efficacy of low-level laser technology for treatment of androgenetic alopecia.

Is Capillus good for use after hair transplant procedures?

Yes, Capillus uses safe, low-level lasers to stimulate, energize, and renew cells within the hair follicle for thicker, healthier hair. It also helps those who’ve undergone a hair transplant procedure to protect the new hair growth. Follow your transplant physician's directions for follicle support after transplant.

Are Capillus products safe for women?

Yes. Unlike some prescription medications for hair loss, Capillus low-level laser therapy (LLLT) products are safe for use by women.

In fact, the convenience and effectiveness of personal LLLT products makes the Capillus products the first choice among many hair restoration surgeons who treat women suffering with thinning, shedding, or balding.

What is the difference between lasers and LEDs for hair regrowth?

Capillus laser therapy devices use only medical grade laser diodes as a light source. What does this mean? You get the right amount of light energy exactly where you need it. Capillus uses lasers because the output penetrates deeper, better and is clinically proven to be therapeutic for their specific purpose.

Laser light does not spread as much as LEDs over the same distance, which allows lasers to penetrate tissue to a deeper level with higher concentration. For photobiomodulation therapy, the farther the light is from the target, the less intense and less effective the treatment will be.

For light therapy to be effective, it needs to reach the cells that respond well to photobiomodulation therapy.

LASER stands for Light Amplification by Stimulation of Emitted Radiation. This simply means that a source of light is amplified within a gain medium and emitted in a specific way. LASER produces a very intense beam of light which has the following properties:

  • Monochromatic (meaning it consists of one wavelength)
  • Coherent (meaning all parts are in phase)
  • Collimated (meaning all parts travel in one and same direction)

LED stands for Light-emitting Diode. And it’s pretty much just that. A diode that emits light when electricity passes through it. Often in pretty colors.

LED light can produce collimated light (with a focusing lens) but not coherent light thus they do not concentrate all their power in a coherent beam. Laser diodes by definition produce effective collimated and coherent light output.
