REVIAN RED Hair Growth System
Product image: REVIAN product page.
REVIAN RED is an LED cap with 119 LEDs that combine red (660 nm) and orange (620 nm) light, which the brand calls dual-wavelength technology.
Sessions are 10 minutes a day. The cap is cordless but runs through the REVIAN app, so you need a smartphone. REVIAN offers a full refund if you use it at least 145 of 180 days and don't see results. The FDA record shows a 510(k) clearance (K173729).
It's the only device we list that pairs red with orange LED light. At $1,995 it's at the higher end on price, though the brand page showed a $400 promo code. Hair loss has many causes, so see a dermatologist before you buy.

"FDA-cleared" means we matched this product to a 510(k) record: the FDA cleared it as substantially equivalent to an existing device for its labelled use. FDA clearance is not FDA approval, and a listed specification isn't proof that a device works. How we check FDA status.
Terms on this page
- nm
- Nanometres, the unit for a light's wavelength (its colour). Red light is roughly 620–700 nm; near-infrared is above 700 nm.
- 510(k)
- The FDA premarket notification route. A cleared 510(k) means the FDA found the device substantially equivalent to one already on the market. It is not FDA approval.
- Diodes
- The individual light sources in a device: LEDs, which spread light, or laser diodes, which produce a narrower beam.
