If hair loss doesn’t give you peace and no treatment has paid off so far, then there’s a good call to try iRestore. Usually, most people start to treat thinning hair in the same way: shampoossupplements, and drugs. No doubt, shampoos can’t do much about your condition because they don’t penetrate deeply into the scalp and can’t affect hair follicles. Drugs and supplements may work, but they can take up to three years to show results, plus there are side effects that you have to consider.

However, things are different when it comes to iRestore or any other laser hair growth device. Because lasers can penetrate the scalp more in-depth than any other treatment, they can trigger biochemical changes within body cells to reduce hair loss and stimulate follicles to produce healthier hair. And there’s a lot of scientific data that proves it. Have we got your attention already? Good as there’s a lot more about iRestore to find out.

What iRestore is?

iRestore Laser Hair Growth System is an FDA-cleared hair recovery device built by Freedom Laser Therapy Foundation. It uses low-level lasers for treating alopecia, receding hairline, balding, thinning hair, and stimulating hair regrowth for men and women. The whole therapy with iRestore can be performed in your home’s comfort, and the process is extremely simple — more about that in a bit.


iRestore laser hair growth system review

Since iRestore is one of the best-performing and most popular laser hair growth devices, we’ve created this article to review it based on customer reviews, specifications, real results, and clinical trials.

How iRestore promotes hair growth?

iRestore uses the energy emitted by low-level medical-grade lasers to irradiate photons into the scalp tissues, activating the hair growth phase. This procedure is called low-level laser therapy (LLLT), and its potential in hair recovery treatment was discovered by Endre Mester, pioneer of laser medicine. Since then, LLLT has kept being tested and developed to a point where everybody can enjoy its benefits at home, without the need for recovery or medical attention. 

How does the entire process work?

Before starting any hair loss treatment, you should know how the process works and what it does to you. 

Your hair is always in one of these three phases of the hair growth cycle: anagen (the growth phase), catagen (the transitional stage), and finally, telogen (the resting phase). While your hair is in the catagen or telogen stage, it is not growing. Only when it’s in the anagen phase, the hair it is actively growing. What low-level laser therapy does is that it modifies the process of hair weakening by feeding light energy to your hair follicles. It stimulates cell metabolism rate and improves energy production so that more hair will be moved into the growth phase.

This system also counteracts hair loss to enlarge the growing stage, which reactivates dormant follicles and encourages hair growth. Research confirmed that laser phototherapy could trigger anagen re-entry in telogen hair follicles, prolong the anagen phase’s duration, improve proliferation rates in active anagen hair follicles, and prevent premature aging of hair follicles. All that can be done with a single device — iRestore. How cool is that? 

About iRestore

The Freedom Laser Therapy Foundation developed iRestore in two different versions: Essential and Professional. While the number of lasers represents the only difference between them, both versions can grow new hair and recover the lost one. iRestore Essential is built with 21 red medical-grades lasers and 30 red super-luminescent light-emitting diodes configured within an outer helmet and protective inner liner.


The use of lasers and non-laser LEDs are meant to provide complete scalp coverage of the top of the head, the area most affected by hair loss. On the other hand, the Professional version uses 282 lasers, divided into 82 medical-grade lasers and 200 red luminous LEDs.

Do more lasers promote faster hair growth?

With a higher number of lasers, iRestore Professional can cover more of the scalp and reach areas that the Essential version can not. However, the National Advertising Division claims that more lasers could not regrow the hair faster.

In one of their dispute with Capillus, another LLLT device, they state that “there was no evidence demonstrating that additional lasers are more effective in regrowing hair and impeding hair loss than laser comb devices with fewer lasers.” That being said, iRestore Professional does not promote faster hair growth, but it offers more coverage and deep penetration of the scalp, which means it can work for severe conditions.

Does iRestore really treat hair loss?

Yes and no. LLLT has been subject to many clinical trials in the past years, which have shown great potential in recovering lost hair. However, as the process depends on the condition’s severity, genetics, and lifestyle, it’s not fair to say that it’ll work for everyone.

There might be cases where iRestore just doesn’t work and bring you more frustration. If you lose hair severely, and you believe that using only this device will get all your hair back, you’re most probably wrong. In such cases, it’s not about the device’s capability but about a series of habits that you might want to stick to. From a healthy diet to exercise, the products you use for hair, and supplements, everything plays a role in how the device will perform for severe hair loss conditions.

Facts that approve the product’s quality

iRestore holds clearances by the FDA for its safety and efficacity. In a 2016 research, a few doctors have clinically studied iRestore and demonstrated that this device improves hair growth for men and women. In this specific research, surprisingly, 100% of people saw a noticeable increase in hair density with an average gain of 57.91% in hair count.

For another study, 60 men and women with pattern hair loss and thinning hair were selected to participate in a 4-month trial, conducted by dermatologist Dr. Adam Bodian. While 30 people were given an iRestore System, the other half received various treatments for the same purpose: recovering and treating hair loss. By the end of the four months period, the iRestore group showed almost 100% improvements in hair length, growth, density, thickness, and volume, with no adverse effects and no injuries. In comparison, the other patients had a rate of just 21% success.

How safe is iRestore Hair Loss Treatment?

iRestore features medical-grade lasers (Class 3R) and light-emitting diodes cleared by the FDA. The good news is that there hasn’t been reported any case of side effects, nor anyone ended being harmed by using the Freedom Laser Therapy device. Still, your eyes are exposed to potential risks if you look directly into the lasers. Anyway, these are situations that can be easily treated at home. Besides all these, the lasers do not emit heat or radiation, and the treatment is entirely pain-free. The FDA clears these lasers for both safety and efficacity. iRestore System also features the following certifications that guarantee its customers’ safety:


How long should you wait for the results?

iRestore center affirms that you can expect visible results in hair growth and reduction in miniaturization of hair follicles in the first 2 to 4 months, while the entire treatment can last up to 6 months.

How does the progress look over time?

Hair loss treatments take time, and you shouldn’t rush the process as it can reduce the therapy’s effects or even worsen your condition. For the first two months, your tinny hair will fall and be replaced with stronger hair. After that point, hair loss should already be stopped or at least slowed down. Between 5 and 6 months, you can expect visible hair growth with an accelerated recovery rate. After 6 months, the treatment can be interrupted or continued for maintaining your hair condition at its best.

How to use the iRestore Laser Hair Growth System?

There is a full guide on their official website that you can check out. Follow each step carefully for your protection and best results: How do I use the iRestore Pro device?

How often you should use iRestore Laser Hair Growth System

It’s recommended to use the system daily and no more than 25 minutes per session. Do this every day for 4 to 6 months until you achieve optimal results. Then use it as often as desired to maintain the effects and keep your hair & scalp healthy.

What you should know before using iRestore

It always helps to use a special shampoo that stimulates hair growth. Don’t forget that it’s suggested not to use iRestore if you are under 21, without consulting your doctor.

May I run other treatments while using iRestore?

Of course. Physicians consider that the combination of LLLT with other treatments, such as topical products, minoxidil, finasteride, supplements, gives better results. However, other products or treatments are not required and do not necessarily help.

Comparison with other well-known hair loss treatments

Let’s take the game to the next level: how iRestore stands in front of the HairMax device? Based on a study conducted by Dr. Adam Bodian for a test purpose, iRestore performance and results are 15.6% better than HairMax’s ones. This outcome is based on the product/treatment responding time, system quality, risk level, and price.

iRestore customers reviews

These are just a few examples of the most frequent reviews we found for iRestore:

  1. I’m thrilled with the results in only three months of use.
  2. I have been using it for about 6 weeks now and starting to see the results in my problem areas. It’s such a boost of confidence!
  3. I have been using the system for 2 months and have noticed some overall improvement. Enough to say its working as it advertised.

Is iRestore worth buying?

Since the iRestore battery lasts up for lifetime treatment, it can be cheaper than most hair recovery treatments for home use. Considering a shampoo or oil costs up to $80 and you have to replace it once every 2 – 4 months, you’ll realize that you would spend more on these products in just two years than you would pay for iRestore.
