Independent device research

Twelve months to find out if it works. Then your money back.

Laser therapy is slow. The trials needed 16 to 48 weeks to show a result, which is exactly why iRestore's full-year refund window matters more than any spec on the box.

You already know why you are here.

You tilted your head under the bathroom light and saw more scalp than last year. Then you searched, and the internet handed you a $2,699 helmet, a wall of five-star reviews, and a before-and-after photo taken in suspiciously better lighting.

Here is the trap: the devices are real, the therapy is real, and almost everything written about them is written by someone earning a commission on the most expensive one.

We earn a commission too. So we are going to show you our work.

The before-and-after nobody will show you

Not a photograph. A measurement, from a published trial, with the placebo arm printed next to it so you can see what the light actually did.

The only before-and-after worth showingMeasured hair density, treated scalp, 12-month helmet-device trial.

Before baseline

99.2 hairs/cm²

After week 48

124.2 hairs/cm²

A gain of 25 hairs per square centimetre after 48 weeks of three sessions a week.

In the sham-controlled trial, the group wearing an identical but inert helmet gained 0.72 hairs/cm². That is the number that makes the one above worth believing.

We do not publish before-and-after photographs. A photo taken under different lighting six months apart proves nothing, and every brand in this category knows it. These are measured counts from published trials, not our customers and not our claims.

What people who actually used it said

Real, published accounts, every one linked so you can read it in full and in context. We do not write testimonials, and we do not pay for them.

After just two months, my husband saw enough hair regrowth that his college friends commented on it.
WIRED, 9/10Julia Forbes, Review: iRestore Elite Laser Hair Growth System
The shedding fully stopped and I have lots of little new hairs coming in. It is definitely worth it.

It has a 12 month refund window, so it gives you time to get hair growth going.

So which one do you actually buy?

The difference between iRestore's models is coverage, not power. Buy the amount of scalp you actually need treated, and use the full year to find out whether it works on you.

Most coverage

iRestore Elite

$2,699

500 emitters, the widest scalp coverage sold for home use. The right choice when your thinning is diffuse rather than concentrated at the crown. A full year to return it.

Best value in the range

iRestore Professional

$1,499

282 emitters at $5.32 per diode, the lowest cost per unit of light iRestore sells. It covers the crown and mid-scalp, which is where pattern hair loss usually starts.

Why it beats the Essential

If the price is the problem

The cheaper alternatives

from $849

Theradome and HairMax sell FDA-cleared laser devices for under $1,000. You give up coverage and, in most cases, the year-long refund window. We lay out the trade honestly.

Three unbranded laser hair-growth devices: a rigid helmet, a soft cap and a handheld laser band

Helmet, cap, or band?

The form factor is not cosmetic. A rigid helmet treats the whole scalp hands-free but pins you to a chair for 25 minutes. A soft cap lets you walk around. A band finishes in 90 seconds but you have to hold it.

Adherence, not diode count, decides whether you still have gains in month eight. Pick the one you will actually keep using.

The research, without the marketing

What iRestore really costs

$799 to $2,699, and how that stacks up against minoxidil, finasteride and a transplant across five years.

If the balding area of your scalp is already smooth, no laser device on this site will help you. We would rather tell you that than sell you a $2,699 helmet.

Red light stimulates follicles that are weakened but alive. Everything we recommend depends on that one condition. Read how we evaluate devices, then start with the device comparison.
