Proven Industry Leadership
Apira Science is a trusted leader and pioneer in Low-Level Light Therapy (LLLT). In working with teams of scientists in photo medicine and experts in optical engineering for over a decade, Apira Science has emerged as the preeminent specialist in innovative home-use light therapy solutions. The iGrow Hair Growth Platform is the result of Apira's decades of experience, scientific innovation and knowledge of the application of LLLT.

In addition, the iGrow is FDA 510k cleared for men and women. Some companies achieve FDA clearance through a shortcut method, by claiming that their product is "just like" products already on the market. At iGrow, we did it the right way: double-blind clinical trials, with results reviewed by a third-party institution and published in a prestigious medical journal. Our impressive results - a 35% increase in hair growth - reflect iGrow technology - not someone else's.

Questions About LLLT
What is LLLT?

LLLT is an acronym for Low-Level Light Therapy. This refers to a therapy that utilizes laser or light energy below a specific energy threshold and within a specific wavelength. Light sources used for LLLT may include laser and LED devices. Laser devices used for LLLT are also referred to as cold lasers. LLLT devices produce no heat, are safe and cannot burn or injure the skin.

How does LLLT work?

Multiple clinical studies have shown the effectiveness of Low-Level Light Therapy in promoting hair growth in men and women with androgenetic alopecia. The exact mechanism is not fully understood, but the most recent research has identified that LLLT is absorbed into the cells, triggering enhanced cellular activity. In other words, the theory is that LLLT makes aging cells more active, thereby increasing their effectiveness in hair growth.

Are there any medical studies (clinical trials) that support the use of LLLT for hair growth?

Yes! Please see our page on clinical studies, here.

Do physicians advise the use of LLLT for hair growth?

Yes, medical doctors, including dermatologists, in the United States, Europe and Asia prescribe the iGrow® for use with male patients suffering from androgenetic alopecia.

What is the benefit of a device that combines both laser and LED light?

Red light from laser and LED devices emitting 650-670nm wavelength light can stimulate cells within the follicle, as part of an effective LLLT hair treatment. The laser light produces a specific wavelength that is believed to stimulate the hair follicle cells. The LED light uses a broader beam of gentle light energy to cover a wider area of the scalp. Combining the lasers and LEDs offers the benefit of both light sources for men and women with androgenetic alopecia (thinning hair). But the proof is in the results. The iGrow Hair Growth System has shown the highest percentage increase in new hair growth of any published clinical studies on light mediated hair growth.

How does wavelength affect LLLT for hair loss treatment?

It is important to use light within the recommended wavelength for laser hair treatment. Research studies suggest the most effective wavelength for hair growth is between 650-670nm. This wavelength has the most efficient and effective absorption that is essential for hair growth.

Do all LLLT devices use laser and LED together?

Most LLLT devices use either LEDs or lasers. The iGrow® by Apira Science, Inc. utilizes both high-quality laser and LED light sources. This form of LLLT is effective for hair growth in men and women with genetic-based hair thinning/loss.

Will all laser and light devices provide equivalent results on the scalp?

No. Not all devices have the same power and energy output, and therefore, will not yield the same results. Many devices only cover a limited area. Most of these devices require the user to manually move a hand-held comb or brush repeatedly over the scalp for 10-20 minutes at a time. This is tiresome and does not provide consistent application of the light. The iGrow® combines laser and LED light in a hands-free automated device that is easy to use, while providing consistent scalp coverage in each 20-25 minute treatment session.

Can LLLT be used with treatments such as Rogaine or Propecia?

LLLT can be used with hair loss products Rogaine or Propecia. However, the use of pharmaceuticals is not required to achieve results with the iGrow®. That’s what’s great about the iGrow! It is a product that requires only a one-time investment. The iGrow causes no side effects, isn’t messy and is very easy to use.

Using an LLLT Device
If 3-4x a week has good results, will more frequent sessions yield a better result?

There is no evidence that increased Low-Level Light Therapy (LLLT) will provide better results. LLLT should only be used as prescribed. Each LLLT session should be followed by a period of rest. This translates into alternating session days.

How long will I need to continue LLLT sessions?

Hair loss is a progressive condition. If untreated, you can expect to lose more hair over time. After the initial 4 to 6 month LLLT treatment period, you should continue sessions once or twice per week to maintain your hair quality.

I just noticed my hair is beginning to thin - is it too soon to start LLLT sessions?

The iGrow® is intended to be used by men and women who are afflicted with androgenetic alopecia. LLLT hair treatment should be incorporated into your weekly preventative maintenance routine to preserve and strengthen existing hair and provide a healthy environment for continued growth.

At what age is it safe to start LLLT?

LLLT is effective in men and women ages 18 and older. Please consult your physician if you are under the age of 18.

Can LLLT be used after transplant surgery?

Yes. LLLT can be used immediately after transplant surgery. Doctors have reported that using LLLT can help stimulate healing of the wounds, and improve transplant results in hair loss patients. In fact, hair transplant surgeons worldwide have chosen to use the LLLT to improve results. Anecdotal reports have shown that LLLT sessions immediately following surgery decrease the recovery time in hair transplant patients and increases hair thickness. Consult with your transplant surgeon, for more information.

Are all LLLT devices safe to use after transplant surgery?

No. After transplant surgery, it is important that your scalp does not come into direct contact with any foreign object. Many devices use teeth or spikes that are studded with a laser. You should not use such devices as they will damage your transplant. Instead, use a device that covers the entire scalp but does not directly touch the scalp. At the present time, only the iGrow® by Apira Science is safe and effective for patients immediately following transplant surgery.
