Follicular Changes and Melanin Synthesis of C57BL/6 Mouse Model with Sasam Extract

In this study, different types of catagen in the C57BL/6 mouse model exhibited varying effects on hair follicle melanocytes and melanin distribution, with spontaneous and dexamethasone-induced catagen showing pigment incontinence, while cyclophosphamide-induced catagen retained dendritic melanocytes but increased ectopic melanin.

This study observed that injecting mice with α-MSH resulted in black hair regrowth in shaved and plucked areas, suggesting a potential link to the agent darkening hair in animals with a specific pituitary tumor.

This study found that splenic melanosis in C57BL/6 mice is associated with synchronized skin melanization during hair cycles, but decreases with age.

This study found that the switch-off of melanogenesis during the hair cycle in C57 BL-6 mice is a gradual and stochastic process starting in mid anagen VI, with specific biochemical markers indicating the transition to catagen.

This animal study observed that while topical MBEH and intraperitoneal phenol induced hair graying in eumelanic mice, they had little effect on pheomelanic mice, and amcinonide reduced certain epidermal melanocytes in both.
