research The Effect of Carcinogenic Agents on the Phosphorus Content of Hair Bulbs and Epidermis
research Noninvasive method for assessing the human circadian clock using hair follicle cells
Scientists found a new, less invasive way to study body clocks using hair cells, which shows shift workers' body clocks don't match their lifestyles.
research Effects of ultraviolet B radiation on physicochemical properties of human hair shaft
UVB radiation changes the chemical makeup and dries out human hair but doesn't alter its appearance or texture.
research Photobiomodulation: A Systematic Review of the Oncologic Safety of Low-Level Light Therapy for Aesthetic Skin Rejuvenation
Photobiomodulation is safe for skin rejuvenation, even for those with a cancer history.
research Melanogenesis During the Anagen-Catagen-Telogen Transformation of the Murine Hair Cycle
Hair stops producing melanin as it transitions from the growth phase to the resting phase.
research Commentary
The Epilight Hair Removal System is effective for temporary hair removal with few side effects, but more research is needed to confirm its safety and long-term results.
research Scientific Opinion on the substantiation of a health claim related to spermidine and prolongation of the growing phase (anagen) of the hair cycle pursuant to Article 13(5) of Regulation (EC) No 1924/2006
