Aging causes hair loss and graying due to stem cell decline and changes in cell behavior and communication.

The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.

DNA methylation is essential for skin and hair follicle development, and could be a target for treating skin diseases.

The conclusion is that skin and hair patterns are formed by a mix of cell activities, molecular signals, and environmental factors.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

GRK2 is essential for healthy hair follicle function, and its absence can lead to hair loss and cysts.

Astragalus sinicus extracts may help promote hair growth and treat hair loss.

Hair loss caused by genetics and hormones; more research needed for treatments.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

Lymphatic vessels are important for skin repair and could affect skin disease treatments.

The conclusion is that hair growth can be improved by activating hair cycles, changing the surrounding environment, healing wounds to create new hair follicles, and using stem cell technology.

The document suggests that activating autophagy might help with regeneration by removing old and damaged cells.

Chilled ATPv-supplemented saline best preserves hair grafts' key genes.
