iRestore Laser Hair Growth System

Home Laser Therapy Vs Other Market Options

Hair loss, hair thinning and/or slow regrowth can be a brutal experience.

It can be very painful to find confidence in a society that demands perfectionism when it comes to your appearance and then defines perfectionism as a full and healthy crop of hair. 

Hair loss, therefore, becomes an isolating experience because there might be days you do not want to go out because you do not have the energy to style your hair to hide those balding parts. Perhaps it has come to the point where your social life and social circle is determined by your hair or the lack of it.

So what are the options available for you?

You can try different alternatives which include:

Today, our review is on the iRestore Laser Hair Growth System, if you want to consider Home Laser Therapy as the solution to your hair problem. While Home Laser Therapy is cheaper compared to hair transplant surgery, it is costly compared most of the alternatives displayed above.

In order for you to not a make a mistake, we cover everything you might want to know about the iRestore brand to make an informed and educated purchase decision.

What is the iRestore Laser Hair Growth System? 

The iRestore Laser Hair Growth System is designed by the Freedom Laser Therapy company founded by Craig Nabat in 2003. It is a hair growth system using Low-level Light Therapy. The system has a collective 11, 700+ reviews on Amazon and Google reviews. 

It is clear that the product is reputed. 

But did you know?

Today, there are actually two iRestore Laser Hair Growth Systems as showcased below:

iRestore Laser Hair Growth System – EssentialiRestore Laser Hair Growth System –  Professional
Price: $695.00 USD
Equipped with: 51 medical-grade lasers and LEDs
Coverage: Top scalp, crown and hairline.
Price: 965.00 USD
Equipped with: 282 medical-grade lasers and LEDs
Coverage: Extended scalp coverage
compared to the Essential on the sides
and the back of the head.
Technology Used Includes:

Use of Low-level Light Therapy (LLLT) to stimulate cell metabolism on the scalp and irradiate photons into scalp tissues which are absorbed by weak cells encouraging hair growth and regrowth. Also the products are made with white plastic and have a lightweight design.

In our iRestore review, we will only be talking in detail about the pros and cons of the Essential. However, keep in mind that the main difference between the two is that the Professional is equipped with more lasers and LEDs, and therefore covers more scalp regions than the Essential.

The Irestore Essential is a product that comes with a dome (that is attached to a controller), an AC adapter and a user manual. There is an option to purchase the iRestore Essential System with a Rechargeable Battery Pack at $635.00 USD which is cheaper than the system itself at the moment priced at $695 USD.

Different parts of iRestore Essential

Now let’s take a look at who the product is suitable for. 

Who is it Suitable for?

The Irestore Laser Hair Growth System is suitable for men and women aged above 18 years with:

  • Androgenetic Alopecia/ Androgenic Alopecia
  • Receding Hairlines
  • Thinning Hair 
  • Balding Hair

The Irestore Hair Growth System is not suitable for:

  • People with skin sensitivity to light or people taking photo-sensitizing medication.
  • People who have been bald for years or have severe hair loss.
  • People who have cancer on the scalp.
  • People who are allergic to this specific wavelength of light (640-665 nm).
  • Men who are beyond class V of the Norwood-Hamilton Scale:
iRestore is suitable for men in Class IIa to V of the Norwood-Hamilton Scale
  • Women who are beyond Class II of the Ludwig-Savin Scale:
iRestore is suitable for women in the Class I to II of the Ludwig-Savin Scale
  •  Men and women who are Type V to VI on the Fitzpatrick Skin Type Scale:
iRestore is suitable for men and women Type I to IV on the Fitzpatrick Skin Type Scale
iRestore is suitable for men and women Type I to IV on the Fitzpatrick Skin Type Scale

Thus the iRestore system is only suitable for people who have the above characteristics. 

Note: Its effectiveness has only been clinically tested for men aged between 18-48 and women aged between 18-60. However, just because it has not been scientifically tested does not mean it will not work for anyone outside that age category. Also if you are pregnant or breastfeeding, consult a doctor before undergoing any laser therapy.

Now let’s take a look at the science backing up the iRestore Laser Hair Growth System.

The Science behind the iRestore System

The Low-level Light Therapy System used by iRestore is a non-invasive treatment for hair that is drug-free and FDA certified. LLLT, which is also called red light therapy has the ability to stimulate cell metabolism.

How iRestore stimulates cell metabolism

So while you may feel like a Christmas tree wearing the white and red dome on a weekly basis, it is doing an important job of stimulating your scalp to encourage healthy hair growth. Given below is a visual representation of how it works.

How does iRestore grow hair when exposed to red light

And do you want to know the best part?

To back up their claims the company has even done a double-blind placebo-controlled clinical trial with 40 people for 4 months to study the effects of the iRestore on hair growth.

What does that mean?

It means that they took 40 men and women, aged between 18 to 48 and 18 to 60, respectively, and gave 20 of them a fake system while the other 20 were given the actual iRestore Laser Hair Growth System to test its effects. The study went on for 4 months to determine hair growth overtime.

Given below is a pictorial depiction of the results.   

Results of the iRestore Clinical Study

43.2% increase in hair growth! Sounds too good to be true right? 

That’s why after presenting to you the science behind iRestore, now it is time to check what real life verified users who actually purchased and used the product are saying.

Check the next section for the side effects.

Possible Side Effects of Using the iRestore System

Here we cover the side effects to look for while using the system.

  • May cause scalp irritation. If the irritation persists 1 hour after using the dome, discontinue use and consult a doctor.
  • Keep all parts of the system away from water sources to avoid electric shocks. Also keep the product away from the reach of children and pets. 
  • May cause mild headaches. If the headaches persist. Discontinue use and consult a doctor.
  •  While LLLT has been scientifically linked to benefits such as treating acne, dead skin cells, herpes virus lesions, vitiligo, psoriasis, hypertrophic scars and keloids, if you are light sensitive or have allergic reactions to certain wavelengths of light (640-665 nm) – it may harm you.

HairMax LaserBand 41

Design: Crescent shaped laser tooth comb band with 41 medical-grade lasers. No LEDs.

Company: HairMax based in the USA

Founded: 2000

Purpose Commitment to helping people regrow hair as a driving force of the company – Total focus. No exceptions.

iRestore Vs CapillusUltra Cap

CapillusUltra Cap

Design: A cordless cap designed with 82, 5mW laser diodes.

Company: Capillus in the USA

Founded: 2012

Purpose: Offers laser treatments with special formulated ingredients to super charge hair growth.

Capillus laser caps stimulate the enzyme, cytochrome c oxidase, so that it produces energy that is used to repair damaged tissues and kick-start hair growth. Using the caps regularly for only 6 minutes a day yields remarkable results for androgenetic alopecia.

Currently it is the cheapest option along with the iGrow helmet.

Other Laser Hair Growth Products: The Pioneers series include the One, the Plus, the Pro with 112, 202, 272 diodes, respectively. The Smart Hair Growth series include the One S, the Plus S1, The Pro S1 with 128, 214, 304 diodes, respectively. Depending on the number of diodes and the technology used, the price mark goes up.

iRestore Vs Theradome EVO LH40 

Design: Cordless white laser helmet with 40 medical-grade lasers.

Company: Theradome Inc. based in California

Founded: 2009

Purpose: Commitment to restoring hair health and confidence of people all over the globe.

The Theradome Laser Hair Growth Therapy System is based on four principles: effective cold lasers, powerful red light, optimal energy dosage and maximum therapy. Unlike the iRestore system, it does not use LEDs and utilizes 40 medical-grade lasers to regenerate hair energy and improve hair health.

What happens when you use only medical-grade lasers?

The red light penetrates deeper into the scalp to stimulate cell metabolism because the lasers carry a single-color wavelength unlike the LEDs which carry a wide and incoherent range of wavelengths. 

Right now, the Theradome Evo is pricey compared to the CapillusUltra System and the iGrow Helmet.

Other Laser Hair Growth Products: The Theradome PRO LH80, priced at $995.00 USD which carries 80 medical-grade lasers and has a wider coverage compared to the Theradome EVO.

Currently it is the same price as the CapillusUltra cap.

Now let’s sum up our review on iRestore.

Final Comments on the iRestore System with Pros and Cons

Here we have compiled a list of pros, cons and grey areas concerning iRestore.

Cheaper than hair transplant surgery. Still a considerable investment. Therefore, do your research and educate yourself before making a purchase.
The iRestore System is a one-time purchase
you can keep for a long time with careful usage.
Time consuming as it takes 16-24 weeks to see effects. Moreover, you have to use it consistently 3 times per week.
Clinically proven to help men aged 18-48 and women aged between 18-60. Ineffective for people in later stages of hair loss.
Doesn’t work for everyone.
Is a drug free, FDA certified, non-invasive treatment for hair loss. It may interact with other medication you are
taking such as photo-sensitizing medication. If you have light sensitivity or are allergic to certain wavelengths (640-665 nm)
please do not use this. 
Is a comfortable and hands free option that comes with a headband, foam pads and lightweight design.LLLT is still a field in its infancy when it comes
to hair loss treatment.

Grey Areas:

  • Mixed customer service reception. Amazon reviewers had both positive and negative experiences with the 6-month return policy.
  • You need to integrate iRestore with a good diet + good habits + other hair loss options for the BEST results. A laser hair therapy is no excuse to slack on your healthy food intake, vitamin intake, sleep habits and hair maintenance routine.
  • Oily debris on hair has been linked to interfering with LLLT. Therefore, make sure you are using a deep cleansing shampoo and conditioner for oily hair.

These are the pros and cons. Let us know how you fared if you decided to purchase the product and feel like a Star Wars Stormtrooper 3 times per week.

Hope this helped and we wish you good luck!
