Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

Using human fat tissue derived stem cells in micrografts can safely and effectively increase hair density in people with hair loss.

New treatments for Alopecia Areata, like JAK inhibitors, show promise for hair regrowth and are likely to change future treatment approaches.

Improving the environment and cell interactions is key for creating human hair in the lab.

Older skin has higher cancer risk due to inflammation and stem cell issues.

The vitamin D receptor is essential for skin stem cells to grow, move, and become different cell types needed for skin healing.

Different hair protein amounts change the strength of keratin/chitosan gels, useful for making predictable tissue engineering materials.

BMP6 and Wnt10b control whether hair follicles are resting or growing.

New treatments targeting immune pathways show promise for severe hair loss but need more research for safety and effectiveness.

Hair can regrow in large wounds through a process similar to how hair forms in embryos, and understanding this could lead to new treatments for hair loss or scarring.

Regenerative therapies show promise for treating vitiligo and alopecia areata.

Dying cells can help with faster healing and new hair growth by releasing a growth-promoting molecule.

Understanding hair follicle biology and stem cell control could lead to new hair loss treatments.

Trichoscopy is useful for diagnosing and monitoring alopecia areata treatment.

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

HSP90 and lamin A/C are crucial for hair growth and could be targets for treating hair loss.
