Which hair device for what
We track 15 hair devices. CurrentBody LED Hair Growth Helmet (CurrentBody Skin LED Hair Regrowth, MZ-07) has the highest score, 9.5/10, tied with 1 other model. 13 of 15 have an FDA 510(k) clearance on record. The lowest-priced FDA-cleared option is HairMax Ultima 12 Classic LaserComb at $299. Prices run $299 to $2,499, checked Oct 8, 2026. 1 model is price on request.
The FDA clearances I could read all cover one condition, androgenetic alopecia (pattern hair loss), on skin types I to IV: in men up to Norwood-Hamilton V and in women with early Ludwig-Savin patterns. In sham-controlled trials of laser combs and helmets, people grew more hair than with a fake device over 16 to 26 weeks. That slow timeline is why hair devices come with the longest return windows in our database, up to 12 months at iRestore.
13 of the 15 devices here are FDA-cleared, so clearance alone doesn't separate them. What does: how many minutes a week you'll put in, what you're willing to wear, and how long you get to send it back.
The least time
Mito Red Light MitoGROW Pro (Professional) Laser Helmet12 min, every other day, about 42 minutes a week by Mito's instructions; no price on Mito's site when I checked.

Some records in the database sit outside this table because we don't link to a store for them: HairMax's LaserBand 82 needs the fewest minutes a week of any device here (4.5), its Ultima 12 comb is the cheapest with a 510(k) at $299, iRestore gives the longest money-back window (12-month money-back guarantee if no result), and Capillus, iRestore and REVIAN the longest warranty, 3 years.
Session time is the biggest gap. By each brand's own instructions the HairMax LaserBand 82 ComfortFlex takes about 4.5 minutes a week and the Kiierr 272 Premier Laser Cap about 105. The trials below ran for months, so a routine you'll actually keep matters more than a few extra diodes.
What FDA clearance covers
The clearance text is the outer edge of what any of these devices can claim. Most read like the REVIAN RED clearance: it is "indicated to treat Androgenetic Alopecia and promote hair growth in males who have Norwood-Hamilton Classifications of IIa - V patterns of hair loss and to treat Androgenetic Alopecia and promote hair growth in females who have Ludwig-Savin Scale I-1 to I-4, II-1, II-2 or frontal patterns of hair loss; both with Fitzpatrick Skin Types I - IV."
Three things in that sentence are easy to miss. It covers androgenetic alopecia only, not alopecia areata or hair loss from other causes. It stops at Norwood V, so it says nothing about very advanced loss. And every clearance on this page that I could read is limited to Fitzpatrick skin types I to IV, which leaves out darker skin.

One more finding from the paperwork: the newest caps were cleared without any clinical testing: the 510(k)s for the CurrentBody helmet, the HigherDOSE hat and the Bon Charge cap each say "Clinical testing was not needed", and each points to REVIAN RED as the device it is equivalent to. REVIAN RED's own 510(k) says no clinical trial data was submitted. The Hooga Red Light Therapy Hat is the one device here with no FDA record; Hooga itself calls it a wellness device. All clearances are listed on the FDA-cleared devices page.
What the studies found
The trials behind this category were done with laser combs and helmets, and the better ones used a sham device that looked the same but didn't emit therapeutic light.
- A 2014 set of four sham-controlled trials of the HairMax LaserComb followed 225 men and women for 26 weeks. Terminal hairs rose by 18.4 to 25.7 per cm² in the treated groups against 1.6 to 9.4 in the sham groups.
- A 2013 trial of a 655 nm helmet in 44 men found 39% more hair growth than placebo after 16 weeks of 25-minute sessions every other day. The 2014 version in 47 women found 37%.
- A 2013 trial of a 630 to 660 nm helmet in 40 people found greater density than sham after 24 weeks of daily use; the investigators saw a difference, the participants' own rating did not.
- A 2021 meta-analysis of seven double-blind trials of home-use devices found a significant increase in hair density over sham for both combs and helmets, in men and women.
The limits are real. Reviewers note high heterogeneity between trials and links to industry in some of them (Adil and Godwin, 2017; Egger et al., 2020). And a 2023 trial of 54 people that added a laser device to 5% minoxidil found no significant difference against minoxidil alone after 16 weeks. More on what red light does and doesn't do is on the benefits page. Nothing here is medical advice; see the medical disclaimer.
Laser or LED
Both kinds sit in the same red band, 620 to 680 nm across this list; Celluma RESTORE and Hooga Red Light Therapy Hat also add near-infrared, and Celluma adds blue at 465 nm. The difference is the light source. HairMax, Capillus, Kiierr and iRestore use laser diodes (iRestore mixes lasers with super-luminescent diodes); CurrentBody, HigherDOSE, Bon Charge and REVIAN use LEDs. The trials above mostly used lasers, but the FDA clears both kinds for the same use, and the cheapest FDA-cleared LED caps here ($449) cost about half of the cheapest laser helmet or cap, the iRestore Professional at $899.
What the brands don't publish is the useful number, output per square centimeter at the scalp. Most laser brands quote total milliwatts instead, such as 2,500 mW for the iRestore Elite. Bon Charge's 510(k) lists 18.4 mW/cm², CurrentBody's 1.67 mW/cm². I found no independent measurement for any hair device.
Why money-back windows are long here
Masks here come with 14 to 120 days to return them. Hair devices go further because the trials took 16 to 26 weeks to show a difference: 360 days at iRestore, 210 at Kiierr, 180 at HairMax, Capillus and REVIAN.
Most come with conditions, and the conditions decide whether the guarantee is worth anything. iRestore's refund policy counts "twelve (12) months from the date of purchase" but wants the return request between day 365 and 400, keeps a 25% service fee, makes you pay return shipping, allows one return per household and only for orders from its US site. Capillus explains its 6 months with "it takes time to see the results", keeps a 25% fee and makes you pay shipping; HairMax keeps 20%; Kiierr only accepts returns between day 210 and 240; REVIAN wants you to have used it at least 80% of the time. If you plan to rely on the guarantee, take a dated photo on day one, keep the box and set a reminder for the claim window.
Questions people ask
Can red light therapy actually regrow hair?
For androgenetic alopecia there are sham-controlled trials in which treated groups grew more terminal hairs than the sham groups, for example 18.4 to 25.7 more hairs per cm² over 26 weeks with a laser comb. The FDA clearances are for promoting hair growth in that condition, in men up to Norwood V and in women with early patterns. They don't cover other kinds of hair loss.
How long does it take to see results?
The trials measured results at 16 weeks (Lanzafame, 2013), 24 weeks (Kim, 2013) and 26 weeks (Jimenez, 2014). Plan on four to six months of regular sessions before judging, and check that your return window is at least that long.
Is red light therapy for hair safe for everyone?
The clearances only cover Fitzpatrick skin types I to IV, so people with darker skin are outside what the FDA reviewed. The trials above reported no serious side effects. Each brand's manual lists who shouldn't use it; read it before you buy, and talk to a doctor if your hair loss is sudden or patchy, since that is not the condition these devices were cleared for.
How we picked
Every hair device gets 1.5 to 2 points on each of 5 criteria: FDA record, published specs, price, warranty and returns and owner reviews. The score out of 10 is the sum, from 7.5 to 10. Prices were checked on Oct 8, 2026. Read the full method.
