Photobiomodulation and alopecia: a crowdsourced survey study on patient preferences.

Photobiomodulation is a treatment option for hair loss and is currently FDA cleared for androgenetic alopecia. There are a variety of photobiomodulation devices intended for at-home patient use. However, data examining user preferences is lacking. A social media-based, online survey study was completed to understand patient preferences when selecting a photobiomodulation device. Secondary outcomes examined patient experience with the device. Sixty participants responded to the 21-question survey. The majority of participants had never used a photobiomodulation device ( n  = 50; 86.2%). Most respondents ( n  = 40; 67.8%) felt the efficacy of the device was the most important aspect to consider when selecting a photobiomodulation device. Additionally, a majority of participants thought 15 ( n  = 22; 37.3%) or 20 minutes ( n  = 17; 28.8%) would be a reasonable treatment duration and would prefer a hand-free device ( n  = 51; 86.4%). Of the eight participants who had used a photobiomodulation device, only one was dissatisfied with the device and discontinued treatment.
