Can a cap that emits specific light wavelengths truly reverse hair loss?

In this episode of The Technology of Beauty, Dr. Grant Stevens sits down with John Oakley, CEO of REVIAN, to explore how their patented dual-wavelength LED therapy is transforming hair restoration. Unlike traditional laser devices, REVIAN’s lightweight, cordless cap uses both 620nm and 660nm light to stimulate nitric oxide production, reduce inflammation, and block DHT—all essential to regrowing thicker, healthier hair.

With over 60 patents and clinical data showing significantly greater efficacy than competing therapies, REVIAN is leading a new wave in non-invasive hair restoration. It’s not just about technology—it’s about results. Dr. Stevens and John both use the device personally, and over 55% of users are now women, thanks in part to its ease of use, cordless design, and drug-free, side-effect-free approach.

John shares why this dual-wavelength, LED-powered system is more effective than traditional laser caps and how REVIAN’s smart app brings real accountability to at-home treatment with a fully integrated therapeutic solution.

In a powerful final segment, John opens up about his work in Guatemala with Unearth Hope, a nonprofit bringing basic healthcare to remote villages. His annual mission trips speak to a deeper commitment to healing—whether it’s through light-based therapy or hands-on community care. Don’t miss this inspiring conversation with one of the true innovators in beauty tech.
