Quick Answer: Theradome and Capillus are both all-laser (no LED) hair-growth helmets, but they sit in completely separate price tiers. Theradome’s two helmets — the EVO LH40 ($695) and PRO LH80 ($995) — top out at 80 diodes and a single 680nm wavelength, per Theradome’s own store. Capillus’s six caps start at the 272-diode PRO ($1,699) and climb to the 320-diode MD DUO ($3,699), with the pricier tiers adding a second or third wavelength. There’s zero price overlap: Theradome’s most expensive model is still $704 below Capillus’s cheapest. Choose Theradome for the lowest entry price and a fixed, published session schedule; choose Capillus for more diodes, more wavelength options, and a longer brand track record in multi-tier laser caps.
Theradome and Capillus are two of the best-known all-laser brands in home hair-growth devices, and each already has its own dedicated review on this site — Theradome’s EVO/PRO lineup and Capillus’s six-model lineup. This comparison lines the two brands up directly: diode count, wavelength, price — plus a real pricing error we already caught on Theradome’s own marketing page when it names Capillus directly.
Theradome vs Capillus by the numbers
- Zero price overlap between the brands: Theradome’s priciest model, the PRO LH80, is $995; Capillus’s cheapest model, the PRO, is $1,699 — a $704 gap with nothing from either brand falling in between, per each brand’s own current store.
- Capillus starts where Theradome’s flagship would need to more than triple to reach: the entry-level Capillus PRO (272 diodes) already carries 3.4x the diodes of Theradome’s flagship PRO LH80 (80 diodes).
- Both brands are all-laser, but only Capillus goes multi-wavelength: Theradome uses a single 680nm wavelength on both its models; Capillus’s entry PRO is also single-wavelength (650nm), but the Spectrum ($2,699), TriSpectrum ($3,299), and MD DUO ($3,699) add a second (808nm) or third (780nm) band, per Capillus’s own specs.
- Theradome’s own comparison page misquotes Capillus by $1,300: it lists Capillus Pro at $2,999; Capillus’s real current price for that model is $1,699, a 76% overstatement — and the identical $2,999 figure also appears on illumiflow’s marketing page for the same model, per our Theradome fact-check.
- The misquote inflates the real price gap by 26 percentage points: at the false $2,999 figure, Theradome’s PRO LH80 looks 67% cheaper than Capillus; at Capillus’s real $1,699 price, the PRO LH80 is still cheaper, but by 41% — a real gap, just much smaller than Theradome’s own marketing implies.
At a glance: Theradome vs Capillus
| Spec | Theradome | Capillus |
|---|---|---|
| Diode technology | All-laser (no LEDs) | All-laser (no LEDs) |
| Tiers | EVO LH40 / PRO LH80 | PRO / PRO S2 / PRO S1 / Spectrum / TriSpectrum / MD DUO |
| Entry price | $695 (EVO LH40, 40 diodes) | $1,699 (PRO, 272 diodes) |
| Flagship price | $995 (PRO LH80, 80 diodes) | $3,699 (MD DUO, 320 diodes) |
| Wavelength(s) | 680nm only (both models) | 650nm entry; 650+808nm or 650/780/808nm on pricier tiers |
| Weekly sessions | PRO: 2x/week; EVO: 4x/week (20 min) | 6 minutes daily, all tiers |
| Warranty/guarantee | 1-year warranty, 6-month money-back, 5-yr DomeCare add-on | Not standardized across tiers — check current terms per model |
Theradome: fewer diodes, one wavelength, the lowest entry price
Theradome’s entire lineup is two helmets built around the same proprietary VL680 laser at a single 680nm wavelength — 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 the original fact-check of Theradome’s competitor-pricing page, see our Theradome review.
Theradome EVO LH40
- 40 proprietary VL680 laser diodes at 680nm, delivering 363 joules per 20-minute session, per Theradome.
- 4 sessions a week — more time invested per week than the PRO LH80's 2-session schedule.
- FDA 510(k) clearance K113097 as a Class II laser phototherapy device.
- 1-year standard warranty, with a 5-year DomeCare extension available.

Capillus: more diodes, multi-wavelength tiers, higher price floor
Capillus takes the opposite approach: six current tiers, all laser-based (no LEDs), starting well above Theradome’s entire price range. The PRO ($1,699) uses 272 single-wavelength (650nm) diodes, backed by Capillus’s own published clinical study reporting a 51% average hair-count increase after 17 weeks of daily use. Stepping up through the PRO S2 ($1,799) and PRO S1 ($2,499) keeps the single 650nm wavelength but adds diodes, while the Spectrum ($2,699), TriSpectrum ($3,299), and flagship MD DUO ($3,699) add a second or third wavelength band entirely — something no Theradome model offers. For the full six-tier breakdown, see our Capillus review.
Capillus PRO
- 272 medical-grade laser diodes at 650nm — 3.4x Theradome's flagship diode count.
- 6-minute daily sessions, per Capillus.
- Backed by Capillus's own published clinical study: 51% average hair-count increase after 17 weeks.
- FDA-cleared for androgenetic alopecia, same clearance category as Theradome.
The $1,300 pricing error worth knowing about
Theradome runs its own head-to-head marketing page against rival brands, including Capillus — and we’ve already fact-checked it for our Theradome review. That page lists Capillus Pro at $2,999; Capillus’s own current live store prices that exact model at $1,699, a $1,300 gap (about 76% above the real price). It’s not an isolated typo, either — illumiflow’s own marketing page uses the identical $2,999 figure for the same Capillus model, suggesting a stale number is circulating across more than one rival brand’s comparison content.
The error matters here specifically because it changes how big the real Theradome-vs-Capillus price gap looks. At the false $2,999 figure, Theradome’s priciest helmet ($995) appears 67% cheaper than Capillus. At Capillus’s real $1,699 price, the PRO LH80 is still the cheaper option — but by 41%, not 67%. Theradome genuinely does win on price; the misquote just makes that win look more than half again as large as it actually is.
Which should you buy?
- Buy Theradome if entry price is the deciding factor. The EVO LH40 at $695 is the cheapest all-laser helmet or cap on this site, and Theradome publishes a fixed, specific weekly session schedule (2x or 4x) rather than leaving routine unstated.
- Buy Capillus if diode count or multi-wavelength coverage matter more than price. Even its cheapest tier (272 diodes) beats Theradome’s flagship (80 diodes) by 3.4x, and only Capillus’s pricier tiers offer a second or third wavelength at all.
- Budget-conscious buyers have no real crossover point to compare — the two brands don’t overlap in price at any tier; it’s Theradome under $1,000 or Capillus starting at $1,699.
- If you’re comparing using Theradome’s own marketing page, use the real Capillus prices above instead — the $2,999 Capillus figure on that page is $1,300 too high.
Both brands are FDA-cleared, all-laser designs with no LED diodes — the real decision is whether you want Theradome’s lower price and fixed session schedule, or Capillus’s higher diode counts and multi-wavelength upper tiers.

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, diode counts, and competitor figures were verified against each brand’s own live store catalog (Theradome, Capillus) in October 2026 and change without notice. Nothing here is medical advice — talk to a qualified clinician about hair loss treatment options.
