New treatments for hair growth disorders are needed due to limited current options and complex hair follicle biology.

The microenvironment, especially mechanical forces, plays a crucial role in hair growth and could lead to new treatments for hair loss.

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

Epidermal stem cells have potential for personalized regenerative medicine but need careful handling to avoid cancer.

Hair follicle stem cells can become neural cells using different methods, with varying efficiency.

Aging reduces skin stem cell function, leading to changes like hair loss and slower wound healing.

EGFR helps control how hair grows and forms without needing p53 protein.

Hair loss in Androgenetic Alopecia is caused by genetics, aging, and lifestyle, leading to hair follicle shrinkage and related health risks.

Immune cells are essential for skin regeneration using biomaterial scaffolds.

Tissue engineering could be a future solution for hair loss, but it's currently expensive, complex, and hard to apply in real-world treatments.

Mouse cell exosomes help hair regrowth and wound healing by activating a specific signaling pathway.
