iGrow Laser Review
A relative newcomer to the market, the iGrow is the only helmet-type device we've seen. It has lots of features including an mp3 player connection, meaning you can plug in your iPod to it.
At first glance you might think that this has the most lasers, since it advertises 51 light sources. However, a closer read shows that the iGrow laser has only 21 lasers, along with 30 LEDs. So it really has less than half the lasers of the Super Grow Laser.
The output of the lasers is between 650 nm and 670 nm, putting the lasers in the exact right range to treat hair loss. The output of the laser diodes are 5mw, meaning that the lasers fall into the 'Cold Laser' category.
The LEDs are a bit of a mystery, however. Lasers have a known connection with treating hair loss. LEDs have not been shown to treat hair loss in any way, although there are claims that they can improve skin tone. Since this is meant to be a hair loss treatment, their use in the device is unclear.
The fact that there are 30 LEDs and 21 lasers in the helmet means that the actual lasers are spaced pretty far apart. On average about 1.5 - 2 inches between actual lasers. Of course there are also the 30 LEDs, which, combined with the lasers output plenty of light, but again, only the lasers have a connection with treating hair loss, something to consider.
The unit itself sits above the head slightly, as it rests on your head on four points that hold the helmet above the scalp. These have to be depressed for the unit to turn on, meaning that it won't turn on unless seated on your head (or these points are otherwise pressed). This is a safety feature to prevent you from looking into the lasers directly.
Note: in talking about the coverage of the iGrow laser, we're only going to deal with the coverage given by the actual lasers. While there are also 30 LEDs as well, their lack of evidence in treating hair loss means we're not considering them part of the treatment.
The coverage of the iGrow is better than the X5 Laser by far, since you don't have to move it around by yourself, but not as good as the Super Grow Laser. Since the iGrow rides about an inch over your head, and the bottom is curved, it does give good coverage to the top of the head.
The hairline, however, is not fully covered, and the few actual lasers that come close to the hairline cannot give adequate coverage. The coverage is almost enough but not quite.
Since the unit sits on top of your head, the 21 lasers in the unit sit in the exact same spots for the entire time of the treatment. This means that there is not a lot of distribution of the laser light, and any spot not covered by an actual laser goes uncovered. With the X5 laser you can put the laser right where you want it, and with the Super Grow laser there is natural distribution of the laser due to head movement.
The iGrow laser has the most features of any of the three units. It comes with a little control unit that looks like an iPod Nano, that has buttons to activate its pre-programmed timing and area sessions. In addition to this, it also has headphones built right into the head unit, and you can plug your iPod/MP3 player in and listen while you do the treatments.
The design is the most well thought out of the units we reviewed. It definitely looks like a futuristic helmet that you might see in a sci fi movie.
While the iGrow laser has the most features of any laser hair loss system we reviewed, and while it does come in second in laser count, the inexplicable addition of 30 LEDs makes this unit have poor coverage. Since lasers are what treats hair loss, this unit is, for all its features, stretched a little too thin in getting the laser to the scalp.
Combine that with the highest cost, and this system is not the first choice for treating hair loss.
