September 2017 in “Journal of Investigative Dermatology” In this study, low-dose 453 nm blue light appeared to enhance hair growth by interacting with specific photoreceptors in the outer root sheath cells.
April 2018 in “The journal of investigative dermatology/Journal of investigative dermatology” This study suggests that low-dose blue light (453nm) may positively affect hair growth by interacting with the receptors CRY1 and OPN3 in hair follicle cells.
