About Capillus laser cap

About Capillus laser cap

Capillus products are manufactured by Miami-based Curallux, LLC. They are a leader in medical devices for photobiomodulation therapy, formerly known as low-level laser therapy (LLLT). This treatment approach uses red or near-infrared light to stimulate, heal, regenerate, and protect tissue that has either been damaged or degenerated.

The company creates new personal technology products and ancillary products that can be used by men and women who care about their appearance and want to improve their health.

What Capillus laser cap work for

The company offers a variety of hair care services and products. They can stop further hair loss and promote new hair growth in some cases but, it doesn’t reverse genetic diseases.

In 2007, the FDA first approved low-level light therapy for the treatment of mild to moderate hair fall in the form of a laser cap designed to promote hair regrowth.

  • One of their most popular products is the Capillus laser therapy cap, which many customers say works incredibly well. It is a non-invasive medical low-level laser therapy cap for hair regrowth, offering a safe and easy-to-use method to prevent the progression of hair loss. It also helps restore thinning hair often caused by genetics. It is equipped with laser diodes providing excellent coverage for daily sessions. The device also comes with a long-life rechargeable lithium-ion battery.

The company offers three main caps, each with a different total light output depending on the number of diodes: Ultra (410 mW), Plus (1010 mW), or Pro (1360 mW, which has 3.3 times more laser panels than the first device). These LEDs are safe and cool to touch. More diodes mean more coverage. This, in turn, gives faster results over the same period of use.

All models are designed to be worn for 6 minutes every day, allowing for an even distribution of light therapy. Customers are expected to see results within 6-12 months after using the cap regularly.

How it works

Capillus uses a technique called photobiomodulation therapy to treat hair loss. The procedure is often shortened to PBMT. It is the medical application of laser science to stimulate cell function, rejuvenate tissues, accelerate healing, improve circulation, and reduce inflammation. This therapy is suitable for those with male and female pattern baldness.

When a person’s hair begins to fall out and some or all parts of the scalp begin to go bald, it is usually caused by weak hair follicles. Thus, if a part of the head is bald, it is possible that the cells responsible for hair growth on that part are weak and cannot perform their duties effectively.

When this happens, the cells need the energy to continue to carry out their tasks. This is where the Capillus cap comes in handy. It consists of visible red laser light diode panels useful for stimulating the growth phase and nourishing the cells in hair follicles. Thus, with this stimulation, the cells will be able to efficiently perform their task, and you will begin to notice hair growth.

How effective is the Capillus laser cap? Based on scientific research

Androgenetic alopecia (AGA) is the most common form of hair loss in men and women. Despite frequent emergence, traditional treatments have shown little efficacy, and the search for new treatments continues. Low-level light therapy (LLLT) is a relatively new technique used to stimulate hair growth in both men and women.

Below are studies that support the efficacy of light therapy that is used in Capillus laser cap and other similar devices for hair loss.

A double clinical study [1] involved 40 patients (20 women and 20 men). They were randomized to be treated with a laser helmet or a sham helmet at home for 24 weeks. As a result, the laser helmet significantly outperformed the sham device for increasing hair density and diameter by 4.5 times and showed improvement in hair condition.

The following study [2] was carried out in several institutions and private clinics. Two groups of 146 men and 188 women with typical baldness were examined. A total of 128 men and 141 women were randomized to receive either a laser comb or a sham device and treated their entire scalp three times a week for 26 weeks. Among the patients who participated in the analysis, the average number of hairs increased from baseline by 20.2 per cm², which is an effective treatment. In addition, a large number of patients treated with the laser cap reported an overall improvement in hair loss, hair thickness, and hairiness compared with patients receiving sham therapy.

The following study [3] recruited 47 women with androgenic alopecia. Two groups were created: the first was treated with a red light laser (655 nm), the second was a placebo. Patients received treatment at home every other day for 16 weeks. The results showed a 37% increase in hair growth in the active treatment group compared to the placebo group.

The latest study [4] included 44 men with signs of hair loss. The first group received treatment with a helmet that emitted red light, the second group received placebo treatment. Patients are treated at home every other day for 16 weeks. As a result, a 39% increase in hair was demonstrated in the light therapy group.

Based on research, it can be concluded that laser red light therapy is an effective treatment for hair loss in both men and women. However, it should be noted that the treatment is long-term, and noticeable results can be seen after 6 months.

Bernard, TX

Effective device

“I used plenty of creams, took pills and drugs prescribed by the doctor to heal my thinning hair. As a result, I got nothing but a lot of wasted money. Seeing this device, I got very excited and decided to try it. I have been using this device for 5 months following the directions for 6 minutes a day and I can already tell that it works. My scalp is filling so much that I can see new hair. For some reason, I couldn’t grow my bangs for about a year. And now I notice hair growing in this part. I’m so excited.”

— Lesly, NC

A good alternative to other treatments

“As a doctor, I can claim that laser therapy works great for any person, be it men or women. I believe that some women are not suitable for hair transplantation due to their density is insufficient. Light therapy does not have these contraindications, since it stabilizes the progression of thinned hair.”

— Robert, CA
