Does Laser Hair Growth Really Work?

If you're reading this, you're probably starting to see the tell-tale signs of hair loss. The dreaded shedding, receding hair line or maybe, your hair is already noticeably starting to thin in some places.

Loosing your hair can be alarming at any age and it's something that most of us will experience at some point in our lives. It affects roughly 80% of men and 50% of women world wide.

Many people may tell you that except for expensive hair transplants surgeries or enduring a lifetime of rubbing topical creams on your scalp, that hair loss can't be treated and its an undeniable fact of life.

Well, I'm here to tell you that's simply not true. 

Bring in, Red Light Therapy as a modern hair loss treatment. Or, as its more commonly known: Laser Hair Growth

A non-invasive solution that stops hair loss in it's tracks and can actually regrow your hair using the clinically proven power of red lasers. So, what is Red Light Therapy and does it really work as an effective treatment to regrow your hair?

What is Red Light Therapy (RLT)

When I say red lasers, the first thing that probably comes to mind are ones you see James Bond doing acrobats to avoid in spy movies. In reality, the lasers that are utilized in Red Light Therapy are 100% pain-free, emit zero heat and are completely safe.

Also known as Low Level Laser Therapy (LLLT), the range of benefits that red light therapy provides are seemingly endless. From being used as a serious treatment for major health problems like chronic pain to providing a positive mood stimulation and everything in between.

Rejuvenation at the Celluar Level

LLLT is the process of having red light energy absorbed into the skin which causes a positive biochemical reaction within your cells.

This process increases your cell's metabolic rate and their energy output. Supercharged, once weakened cells are now fully revitalized and your already healthy cells will perform at their peak biological level.

Does Laser Hair Growth Work

When exposing your scalp to red laser light, your hair's naturally occurring growth cycle becomes cellularly stimulated. The red light is absorbed by the hair follicle which gives it the energy to be restored back to it's full growth potential.

Think of it like a splash of water to wake you up in the morning

The same goes for the cells of your hair. The tired follicles that are having a hard time producing healthy hair just need to 'wake up' and become stimulated in order to continue to function properly.

Boosting them with energy, it revitalizes dormant follicles back to life and extends the growth phase of your hair's growth cycle. Restoring the natural production of thick, healthy hair all over your scalp.

The Results of Laser Hair Growth

This is not an over-night solution for hair loss and like every other hair loss treatment, will require you to practice patience and diligence on your part.

Everyone's results vary, but on average, it can take as little as 3 months to start seeing results and improvements.

Major hair growth and substantial improvement will be visible around months 5-6

Treatments are normally done for an average of 20-30 minutes, every other day.

To ensure that you keep & maintain your results, it's suggested that you regularly use laser hair growth as a part of your hair care regime.

The immediate effects within the first 90 days will stop the progression of hair loss and the over-active shedding of your hair.

The next phase, which falls around day 90 - 180, you'll start to see visible hair growth and your existing hair will become thicker and healthier.

And finally, with the continued use of Red Light Therapy, your hair's over all quality and quantity will continue to improve and remain at a healthy state.

Is Laser Hair Growth Right for You?

You Need to Have Some Hair for Your Laser Hair Growth Cap to Work

If you're completely bald and have experienced zero hair growth for years a.k.a. full necrosis (dead hair cells), you're not a good candidate for laser hair growth.

Red light can only energize cells that are still alive, not bring them back from the dead.

Are You Already Seeing the Signs of Hair Loss?

Laser hair growth is the perfect treatment for those who are in a mild to moderate stage of their hair loss. Meaning, you still need to have some hair coverage on your scalp in order for it to be rejuvenated by red light therapy.

Laser Hair Growth was actually medically designed for patients within this hair loss range. If your hair loss stage falls between the mild to moderate categories you'll most likely see extremely beneficial results by using this treatment continuously.

Does Hair Loss Run in Your Family?

Maybe hair loss runs in your family and you want to act now before you even start to experience the first signs of hair loss - you're still a perfect candidate. Red light therapy is the only preventative and non-invasive treatment available to treat hair loss before it even happens.

By keeping your already existing healthy follicles and cells in perfect working condition, you're able to actively prevent genetic pattern baldness before it can even start.  It's never "too early" to start a preventive regimen, especially it applies to your health and well being.

*Laser Hair Growth has been clinically proven and designed to specifically treat reat androgenic alopecia for males who have Norwood-Hamilton Classifications of IIa to V and females who have Ludwig-Savin Classifications of I to II, and for both who have Fitzpatrick Skin Types of I to IV

Is Laser Hair Growth Clinically Proven?

The restorative powers of red light therapy on hair regrowth is backed by a multitude of substantiated evidence gathered from hundreds of clinical trails. When evaluating the efficacy of any medical treatment, its integral to always perform a randomized, double-blind, sham device-controlled trial in order to negate any bias results.

In a 24 week study to determine the effectiveness of Laser Hair Growth Caps for Androgenetic Alopecia (pattern baldness) in both men and women, patients were divided and either given a "true" Laser Hair Growth Cap or a sham device.

After the trial period, patients results were reviewed and it was documented that LLLT is an effective treatment for genetic hair loss, concluding:

"the LLLT group showed significantly greater hair density than the sham device group. Mean hair diameter improved statistically significantly more in the LLLT group than in the sham device group"Dr. H. Kim, Dermatologic Surgery Journal 2013

Another research paper was published in 2014 detailing the benefits of low level laser therapy devices as a safe and effective treatment of both male and female pattern baldness.

Again using a double-blind and sham device-controlled study, the results were extremely conclusive towards the positive benefits of red light therapy for hair regrowth

"...a higher percentage of lasercomb-treated subjects reported overall improvement of hair loss condition and thickness and fullness of hair in self-assessment, compared with sham-treated subjects." - Dr. Joaquin J. Jimenez, American Journal or Clinical Dermatology

Clearly, red light therapy is an effective treatment for hair loss for both men and women.

Several studies have been conducted over recent decades that consistently demonstrate evidence of LLLT actively improving hair volume density, thickness and overall better hair health regardless of the age or sex of the subject.

The Best At-Home Laser Hair Growth Devices

No longer reserved for frequent and expensive visits to the hair growth clinic, you can treat your hair loss with Red Light Therapy from the comfort of you own home. Here are 3 of the most popular devices for At-Home laser treatments to regrow your hair

1) Laser Hair Growth Cap>>

The most advanced and easiest option on the market featuring 80%+ more medical grade lasers. It's been specifically designed for your scalp only and provides full spectrum and targeted coverage where you need it most.


100% hands-free, Laser Hair Growth Caps are worn on your head, just like a baseball cap for a completely seamless treatment. Set with a timer, you're able to walk around and live your life while receiving treatment and it shuts off automatically when it's done.


The initial cost can be higher than the less practical devices mentioned below. Yet, when you break down the dollar cost average over a lifetime of treatments, you'll ultimately own a premium hair regrowth device for pennies per use at the end of the day.

2) Red Light Therapy Lamp >>

A classic way to reap the benefits Red Light Therapy, this is the most "old-fashioned" device on this list. Traditionally reserved for ayurvedic spas, this lamp provides small to medium coverage while requiring total manual adjustment.


This lamp is multi-purpose and can be adjusted to provide a full spectrum of positions that can be applied to every part of the body. It's great if your mostly looking for body treatments but would also like to use it towards your hair health.


The lamp can only target specific areas of the head and will need to be manually adjusted during the treatment session in order to completely treat the scalp. When treating hair loss it's important to heal the entire head for best results and the lamp is no longer the easiest and up-to-date option.

3) Laser Hair Comb >>

An entirely hand-help option for laser hair growth devices, a laser hair comb essentially is a hair brush that uses lasers instead of bristles to stimulate the scalp.


Spot Treatment. Since the laser device is only as big as a hair brush, you can really zero in on a nagging spot that is of particular annoyance.


Get ready for an arm workout - this device is definitely not full coverage.

As mentioned above, you want to ensure your entire scalp receives treatment so you will need to essentially brush your head for 20 minutes.I don't need to go into detail for you to imagine how tired your arm is going to be.

How Does Laser Hair Growth Combat Hair Loss & Hair Fall?

How Laser Hair Growth Works

1. Halts Production of "Balding Hormone" aka DHT

When the red laser light makes contact with the scalp, it inhibits the production of an enzyme called 5-Alpha Reductase - which is key to stopping balding at the source.

This pesky enzyme converts the natural hormone testosterone into tissue DHT (dihydrotestosterone). People who have a healthy head of hair have lower amounts of 5-Alpha Reductase and have less tissue DHT found on their scalp.

2. Increased Cellular Oxygen Intake

Oxygen or lack there-of is another crucial factor to understanding hair loss. Red light boosts oxygen intake by permeating the cell membrane and separating nitric oxide (NO) from the enzyme cytochrome c oxidase (CCO).

They then bind back together, allowing for oxygen to be delivered at a cellular level and lowering cellular respiration. More oxygen can now be delivered to the hair follicles which encourages healthy hair to grow.

3. Increased Blood Flow & Vascularity

Increased oxygen intake, also means increased blood flow. When nitric oxide is introduced to the blood, it encourages vasodilation or the widening of the blood vessels. All the small capillaries in your scalp become open and are boosted with oxygen.

Blockages are cleared moving the blood to your cells, allowing for new hair growth and increased nutrition to already healthy hair.

4. Causes Acute Inflammation

Inflammation is not always a bad thing. While excessive inflammation can spike hair loss, small doses can actually encourage hair growth.

The red light increases your body's naturally occurring inflammatory response to a healthy and therapeutic level encouraging cell reproduction important for hair growth.

5. Activates the Shock Proteins

Heat shock proteins are critical for cellular vitality.

The shock protein called: HSP27 (located in the scalp) becomes activated when it comes in contact with red laser light. Generating a growth boost in the very core of each stem cell of your hair follicle as well as encourages the growth of new follicle stems altogether.
