This article discusses various skin pattern formations, their molecular mechanisms, and highlights the need for further understanding to connect molecular biology with organism phenotypes, without providing new clinical findings.

In this study, rapamycin was found to increase hair follicle pigmentation and prolong anagen duration in cultured human scalp hair follicles, suggesting it could be explored as an anti-greying agent.

This review discusses the cutaneous serotoninergic/melatoninergic system's potential role in skin function and resilience against environmental and internal stresses, but does not report new experimental findings.

This study found that Wnt10b promotes melanocyte maturation and pigmentation in the hair bulbs of mice by activating canonical Wnt signaling.

In this study, γ-ray irradiation of mice reduced hair follicle density and pigmentation, suggesting damage to stem cells and progenitors for keratinocytes and melanocytes.

In this study, researchers found that deleting the Bmi1 gene in murine melanocytes caused premature hair greying and loss of melanocyte lineage cells, highlighting BMI1's role in protecting melanocyte stem cells from stress and oxidative damage.

This review highlights the positive effects of platelet-rich plasma in aesthetic and regenerative medicine, particularly for skin rejuvenation, anti-aging, hair reconstruction, and wound healing, but it reports no new clinical results.

This article in Experimental Dermatology does not include an abstract or any new research findings.

Blond hair in Solomon Islanders is due to a unique genetic variant, not European ancestry.
