A laser comb is the cheapest way in ($299 for the HairMax Ultima 12) but you hold it and move it for 8 minutes, three times a week, with only 12 lasers. A laser band is the fastest (90 seconds a session). A cap is the easiest to live with: hands-free, cordless, 148 to 312 lasers, from $799. A helmet stays put and often mixes lasers and LEDs, from $495. For most people a hands-free cap or helmet is the better buy; a comb suits a small patch, travel or a tight budget.
The four formats in one minute
Laser hair devices come in four shapes, and the shape decides most of your experience.
- Comb. A handle with a short row of lasers, glided slowly through the hair. Example: HairMax Ultima 12, 12 lasers, $299.
- Band. A curved bar of lasers with parting teeth, moved over three areas. Example: HairMax LaserBand 82, 82 lasers, $849.
- Cap. A soft shell with a battery that you wear. Examples: illumiflow 272 Pro, Capillus PRO, Kiierr 302.
- Helmet. A rigid shell, corded or wireless. Examples: iRestore Professional, Theradome PRO.
All four kinds are sold with FDA clearance for pattern hair loss, according to their makers. The differences are about coverage, effort and money.
Coverage: how much light, how many lights
A comb or band shows one strip of scalp to the light at a time; a cap or helmet covers the whole top of the head at once. That is the biggest practical difference.
HairMax says moving the LaserBand 82 over three spots gives the coverage of 246 lasers. The Ultima 12 comb has 12 lasers and HairMax suggests it for targeted areas or a slow full-scalp pass. Caps in our list carry 148 to 312 lasers, helmets 40 to 500 light sources. Our formula scores light-source count on a scale from 12 (1 point) to 312 (10 points), which is why the comb scores lowest on that line and the 300-plus caps highest.
If your thinning is limited to one small area at the crown, a comb can make sense. If it is spread across the top, a cap or helmet does the job without you guessing where you have already been.

Time and effort, honestly
| Format | Example | Routine | Hands-free? |
|---|---|---|---|
| Band | LaserBand 82 | 90 s, 3 times a week | No |
| Comb | Ultima 12 | 8 min, 3 times a week | No |
| Cap | Capillus PRO | 6 min daily | Yes, cordless |
| Cap | illumiflow 272 Pro | 30 min every other day | Yes, cordless |
| Helmet | Theradome PRO | 20 min, twice a week | Yes, cordless |
| Helmet | iRestore Professional | 25 min every other day | Yes, plugs in |
Minutes are only half the story. Eight minutes of holding a comb and moving it carefully feels longer than thirty minutes wearing a cap while you cook. The band is the exception: 90 seconds is short enough to do before you leave the bathroom.
Price per format
On November 11, 2026, the comb cost $299, the band $849, caps $799 to $2,699 and helmets $495 to $1,799. Per light source, the comb is the most expensive way to buy light ($25 per laser), and the iRestore Professional the cheapest of the hands-free devices (under $3 per light source at its sale price).
The guarantee matters as much as the sticker: HairMax gives 6 months on its comb and band, while iRestore and illumiflow give 12 months on some of their caps and helmets. A cheaper device with a shorter window is not always the safer bet.
Who should buy a comb or a band
- You want to test the habit for under $300 and accept a routine where you move the device by hand.
- Your thinning is in one small patch you can target.
- You travel and want something light in your bag (or you already own a cap).
- You will never sit still for 20 minutes, and 90 seconds with the LaserBand is all you will give.
Who should buy a cap or a helmet
- Your thinning is spread over the top of the head.
- You want to put it on and forget about it until it switches off.
- You want the most light for the money: the best value devices on our ranking are hands-free.
- You want to move around (pick a cordless cap or a Theradome) or you are happy to sit (an iRestore helmet).

Mixing formats and travelling
Some people end up with two devices, and it is not as silly as it sounds. A common pattern is a hands-free cap or helmet at home and a comb in the travel bag, so a week away does not break the schedule. HairMax built its range around that idea, and a $299 Ultima 12 next to a cap costs less than a second cap.
If you travel a lot, check three things before you pick your main device:
- Battery or cord. A plug-in helmet like the iRestore Professional needs a socket and a chair. Cordless caps (Kiierr, illumiflow, Capillus, HairMax PowerFlex, REVIAN) and Theradome's wireless helmets go anywhere.
- Bulk. Helmets are rigid and take up a lot of a carry-on. Caps fold flatter; Kiierr and HairMax include or sell carry cases.
- Session length. A 6-minute daily cap fits a hotel morning; a 30-minute session every other day needs an evening in the room.
Do not double up sessions to "catch up" after a trip. Brands set their schedules for a reason, and Capillus warns that exceeding them will not increase the effect. Just pick the routine back up when you get home.
Nothing here is medical advice. Hair loss has many causes: talk to your doctor or a dermatologist before you start a device, and follow the maker's instructions.
