FDA‑Cleared Indications

The REVIAN RED System is cleared to treat androgenetic alopecia and promote hair growth in:

  • Males with Norwood‑Hamilton IIa–V hair‑loss patterns (Fitzpatrick skin types I–IV)
  • Females with Ludwig‑Savin I‑1 to I‑4, II‑1, II‑2, or frontal patterns of hair loss (Fitzpatrick skin types I–IV)
  • Why LED Red Lights > Lasers

    While most hair regrowth caps rely on laser diodes, Revian is powered by patented LED light therapy.

    Its dual-band red light stimulates nitric oxide release in the scalp — a natural biological signal that increases blood flow and reduces inflammation, helping the body create a healthier environment for hair regrowth.l

    Key benefits of Revian’s LED system:

    • Dual‑band LED (620 nm & 660 nm) stimulates the scalp and may trigger local nitric‑oxide release*
    • Completely wireless, 10‑minute daily sessions
    • Bluetooth® app tracks progress and reminds you to treat
    • Comfortable fit—no lasers or heat


  • Clinically Supported for Inflammation & Scalp Sensitivity

    A 2024 study published in Dermatology Times highlighted that red light therapy — especially at the 620 nm wavelength — significantly reduces scalp pruritus, irritation, and inflammation by stimulating nitric oxide production. These benefits make Revian a valuable tool not just for hair regrowth, but also for managing sensitive scalp conditions like medically induced alopecia or plaque psoriasis.

    Scalp symptoms such as pruritus, burning, and irritation are extremely common... Red and infrared low-level light therapy (LLLT) has been shown to induce anti-inflammatory effects... with reduced irritation as a result of nitric oxide release in the skin.”
