April 2018 in “The journal of investigative dermatology/Journal of investigative dermatology” This study observed that Ginseng and Albizia extracts, when used together, protected human dermal papilla cells from oxidative stress-induced senescence, and inhibited genes that suppress hair growth, indicating their potential in preventing age-related hair density reduction.
August 2019 in “Journal of the American Academy of Dermatology” Ginseng and Albizia extracts help prevent hair thinning with age.
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.

April 2017 in “Lasers in surgery and medicine” 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.
April 2018 in “The journal of investigative dermatology/Journal of investigative dermatology” In a laboratory setting, this study found that Biotrinine® dry extract activated hair follicle growth pathways and increased certain growth factor secretions in human dermal papilla cells, suggesting potential benefits for treating chronic hair loss.
