Laser Light Therapy for Hair Restoration

Clinically proven to for Men and Women who have fine, thinning, or weak hairs

How LLLT Works?

  • Lasers are said to work by converting ATP (Adenosine Triphosphate) to ADP (Adenosine Diphosphate),
    releasing energy and causing cellular metabolic changes.
  • During this process, additional nutrients and oxygen are provided to the scalp assisting the normal
    chemical processes performed by those cells, increasing overall blood circulation.
  • The laser penetrates the tissues of the scalp which stimulates the micro-circulation of the blood supply.
  • It supports cell metabolism and synthesizes protein. This process is believed to break down DHT-dihydrotestosterone, the male hormone that causes hair loss.
  • Causes a reduction in inflammation.
  • Stimulates and reverses miniaturized hair follicles.
  • Promotes a, fuller, thicker, shinier, and healthier looking hair.
  • Normalizing sebum in the scalp – either too oily or too dry.


Studies by Dr. Michael Hamblin, associate professor of Laser Medicine at Harvard have been shown LLLT to:

1. Increase Blood Flow in the Scalp
2. Increase cellular activity in the scalp, bringing nutrients into cell while releasing toxins
3. Stimulate the Arrector Pili muscle to increase support of the hair shaft
4. Normalize sebaceous activity
5. Stimulate hair follicles and reverse “miniaturization”

What to Expect?

Patients Must Understand:

  • LLLT is Not a Quick Fix
    – Hair Loss happens gradually, expect loss to be reversed gradually
  • LLLT is a Process
    – Recent studies confirm that the change becomes apparent between 8-12 weeks
    – As the growth cycle of a healthy hair is 1000 day, it can take many months to return weak hair to healthy hair

Stopping Excessive Loss – the most important goal

LLLT – FAQs

What is LLLT?
LLLT is an acronym for Low Level Light Therapy. This refers to a therapy that utilizes RED laser or light energy below a specific energy threshold and within a specific wavelength. LLLT stimulates the follicles, improves cell metabolism and reverses hair miniaturization. Results – thicker hair, more hair, and stablization of hair loss. 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. LLLT is the most clinically studied hair loss treatments in the world.

Do physicians advise the use of LLLT for hair growth?
Yes, Medical Doctors, including dermatologists, in the United States, Europe and Asia prescribe the Grow Laser 272® for use with male & female patients suffering from androgenetic alopecia. In fact LLLT it is the #1 physician recommended treatment for hair growth at home.

Do all LLLT devices use laser and LED together? Are both the same?
Most LLLT devices use either LEDs or Lasers. LED light doesn’t penetrate to the hair follicle level and is also diffused, hence not that effective. All the top clinical research and reports done on LLLT show that true laser diodes are much more effective. Many helmet type devices use a combination of LED and Laser and this can decrease the power and effectiveness of the devices. LED diodes are much cheaper than laser diodes – hence companies use LED to reduce cost. But you must ensure that you choose a true laser diode device for good results.

Grow laser 272 uses true-medical grade 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.

How long do I have to continue Grow LLLT treatments?
Think about LLLT like brushing your teeth, or working out. If you have been working out for a long time, the results will stack over time. But if you stop working out one fine day, you will not loose results gained overnight, but slowly, you will notice a decline in your health.

Similarly, We recommend using Grow Laser for at least 4-6 months consistently. After that period, you should continue sessions for best results. If you discontinue treatment, you will lose the benefits eventually over a period of time.

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 Grow Laser 272 LLLT device is safe and effective for patients immediately following transplant surgery.

How does the Grow Laser 272 compare to other hand held devices?

There are many imitation products on the market, but Grow laser is medically backed by some of the world’s top hair transplant surgeons. In addition Grow Laser 272 comes with a complete plant-based system for enhanced results.

Do physicians advise the use of LLLT for hair growth?
Yes, Medical Doctors, including dermatologists, in the United States, Europe and Asia prescribe the Grow Laser 272® for use with male & female patients suffering from androgenetic alopecia. In fact LLLT it is the #1 physician recommended treatment for hair growth at home.

There are so many treatments for hair loss. How to decide?
There are many treatments for hair loss being marketed. But most of them either don’t work, or too painful, cumbersome, expensive or have too many scary side-effects. Till date – ONLY three treatments have been clinically proven to prevent hair loss and promote hair growth in the world. Finasteride, Minoxidil, and LLLT. Out of those three, two are drugs with side-effects and long-term cost and compliance issues. For women – finasteride isn’t even an option. LLLT has no known side-effects, is drug-free and safe and effective for both men & women. Moreover, if desired can be combined with other therapies.  For your convenience, we have compared ALL The hair loss treatments being sold on the market here.

Can LLLT be used with treatments such as Rogaine or Propecia?
Yes, you can successfully combine Grow Laser 272® with other hair loss treatments, including hair transplant surgery. In fact it is recommended. However, unless you are have advanced stages of hair loss, we recommend that you stick to the HairSmart systems as they have everything you need, and is a drug-free proven system designed for distinct stages of hair loss.

How long will I need to continue Grow 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 for best results. Think about LLLT like brushing your teeth, or working out. If you have been working out for a long time, the results will stack over time. But if you stop working out once fine day, you will not lose results but slowly over time
