    gene regulating body's internal clock and biological rhythms

    PER1, or Period Circadian Regulator 1, is a gene that plays a crucial role in regulating the body's internal clock, or circadian rhythm. This gene helps control various biological processes, including sleep-wake cycles, hormone release, and other daily physiological patterns. In the context of hair biology, disruptions in circadian rhythms can potentially affect hair growth cycles and contribute to conditions like alopecia.
