Quick Answer: iRestore and Theradome both sell FDA-cleared home hair-growth helmets, but they use different diode technology and land at different price points. iRestore’s three tiers — Essential ($799), Professional ($1,499), and Elite ($2,699) — combine laser and LED diodes and scale up to 500 diodes on the Elite, per iRestore’s own store. Theradome’s two helmets — the EVO LH40 ($695) and PRO LH80 ($995) — use only lasers at a single 680nm wavelength and top out at 80 diodes, per Theradome’s own store. Choose iRestore if maximum diode count and coverage matter most; choose Theradome if you want the lowest entry price or an all-laser design with a fixed, published weekly session schedule.
iRestore and Theradome are two of the best-known names in home laser-and-LED hair-growth helmets, and each already has its own dedicated review on this site — iRestore’s full three-tier lineup and Theradome’s EVO/PRO lineup. This comparison lines the two brands up spec for spec: diode technology, wavelength count, price, and warranty — plus a real pricing discrepancy we found when Theradome’s own marketing page names iRestore directly.
iRestore vs Theradome by the numbers
- iRestore has three tiers, Theradome has two: iRestore’s Essential ($799), Professional ($1,499), and Elite ($2,699) scale from 120 to 500 diodes; Theradome’s EVO LH40 ($695) and PRO LH80 ($995) scale from 40 to 80 diodes — per each brand’s own current store.
- iRestore’s flagship has over 6x the diodes of Theradome’s flagship: the iRestore Elite packs 500 combined laser-and-LED diodes versus the Theradome PRO LH80’s 80 all-laser diodes, per each brand’s published specs.
- Different diode technology entirely: iRestore mixes laser and LED diodes (the Elite adds a triple 625/655/680nm wavelength stack), while Theradome uses only its proprietary VL680 laser at a single 680nm wavelength — no LEDs at all, per Theradome’s own site.
- Theradome has the lower entry price: the EVO LH40 at $695 undercuts iRestore’s cheapest device, the Essential at $799, by $104.
- Theradome’s own comparison page misquotes iRestore’s price: it lists the iRestore Elite at $1,799, a $900 understatement of iRestore’s real current $2,699 price, per our Theradome fact-check.

| Flagship price | $2,699 (Elite, 500 diodes) | $995 (PRO LH80, 80 diodes) |
| Wavelength(s) | 625/655/680nm (Elite only) | 680nm (VL680, both models) |
| Weekly sessions | Not published as a fixed schedule | PRO: 2x/week; EVO: 4x/week (20 min) |
| Guarantee/warranty | 12-month guarantee | 1-year warranty, 6-month money-back, 5-yr DomeCare add-on |
iRestore: more diodes, more tiers, laser-and-LED design
iRestore’s whole lineup is the same laser-and-LED helmet technology scaled up three times. The Essential ($799) uses 120 diodes at roughly 600mW total output, the Professional ($1,499) steps up to 282 diodes at roughly 1,410mW, and the flagship Elite ($2,699) tops out at 500 diodes and roughly 2,500mW, with the Elite alone adding a triple 625/655/680nm wavelength stack, per iRestore’s own specs. All three are FDA-cleared for androgenetic alopecia and carry a 12-month guarantee. For the full breakdown of all three tiers, including the brand’s mixed BBB-vs-Trustpilot track record, see our iRestore red light therapy review.
iRestore Elite
- 500 combined laser-and-LED diodes, roughly 2,500mW total output, per iRestore.
- Only iRestore tier with a stated triple wavelength stack — 625nm, 655nm, and 680nm.
- FDA-cleared for androgenetic alopecia, same as the Essential and Professional.
- 12-month guarantee and free shipping, per iRestore's own site.

Theradome: fewer diodes, all-laser design, lower entry price
Theradome takes the opposite approach: two helmets, both using only its proprietary VL680 laser at a single 680nm wavelength, with no LED diodes at all. The EVO LH40 ($695) uses 40 diodes for 20-minute sessions four times a week, and the PRO LH80 ($995) doubles that to 80 diodes for 20-minute sessions twice a week, per Theradome’s own product pages. Theradome holds a specific 510(k) FDA clearance (K113097, filed 2011) and markets itself as the first FDA-cleared all-laser home hair-growth helmet. For the full lineup and a fact-check of Theradome’s own competitor-pricing page, see our Theradome review.
Theradome PRO LH80
- 80 proprietary VL680 laser diodes at 680nm, delivering 727 joules per 20-minute session, per Theradome.
- Just 2 sessions a week — half the EVO LH40's 4-session weekly schedule.
- FDA 510(k) clearance K113097 as a Class II laser phototherapy device.
- 1-year standard warranty, with a 5-year DomeCare extension available.
The pricing error worth knowing about
Theradome runs its own head-to-head marketing page against rival brands, including iRestore — and we’ve already fact-checked it. Per our Theradome review, that page lists the iRestore Elite at $1,799, but iRestore’s own current store prices the Elite at $2,699, a $900 gap. It was actually the smallest miss on Theradome’s comparison page — Capillus, Kiierr, and HairMax were misquoted by larger margins in the same comparison — but it still means Theradome’s own page understates what an iRestore Elite actually costs today. If you’re shopping between these two brands, verify each brand’s price on its own current store rather than on a competitor’s marketing page.
Which should you buy?
- Buy iRestore if raw diode count and coverage are the priority. The Elite’s 500 diodes and triple wavelength stack are the most of any cap or helmet covered on this site, and the Essential ($799) and Professional ($1,499) give you two lower-priced steps into the same technology.
- Buy Theradome if you want the lowest entry price or an all-laser design. The EVO LH40 at $695 undercuts every iRestore tier, and Theradome publishes a specific, fixed weekly session schedule (2x or 4x a week) rather than leaving routine unstated.
- Budget-conscious buyers should compare Theradome’s EVO LH40 ($695) against iRestore’s Essential ($799) — the two closest-priced options across both brands.
- Coverage-focused buyers should compare the iRestore Elite ($2,699) against the Theradome PRO LH80 ($995) — keeping in mind the Elite costs nearly 3x more for over 6x the diodes.
Both brands are FDA-cleared, and both back their hardware with a guarantee — the real decision is whether you want iRestore’s higher diode count and laser-and-LED combo, or Theradome’s simpler, all-laser, fixed-schedule approach at a lower price. For the full field of laser-and-LED helmets and caps, see our best red light therapy cap guide, or compare against Kiierr, Capillus, HairMax, and illumiflow for the rest of the brands we cover.
Red light and laser devices are general wellness products for promoting hair growth in androgenetic alopecia, not a cure for hair loss from other causes. FDA clearance is a device-safety and efficacy finding, not a guarantee of individual results. Prices and diode counts were verified against iRestore’s and Theradome’s own live store catalogs in September 2026 and change without notice. Nothing here is medical advice — talk to a qualified clinician about hair loss treatment options.
