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.

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.

This study found that blue light at a wavelength of 453 nm promoted hair growth ex vivo, potentially through interacting with OPN3 receptors in human hair follicles.

This review highlights the role of the skin's photosensory system in mediating responses to UVA radiation, contributing both to immediate protective effects and to broader circadian and seasonal adaptations, but reports no new experimental results.

This study observed that exposure to different wavelengths of light affects opsin and clock gene responses in skin cells, suggesting potential therapeutic approaches using photobiomodulation for dermatological conditions like psoriasis and wound healing.
