The upper half of a human hair follicle can grow a new hair in a mouse, but success is rare.

Hair can regrow in adult mice's skin after injury, and this regrowth doesn't come from existing hair cells but from skin cells in the wound, with Wnt7a protein helping this process. This could help treat baldness and scarring.

There are two types of stem cells in rodent hair follicles, each with different keratin proteins.

Scientists made skin stem cells from other human cells with over 97% efficiency, which could help treat skin conditions.

Hair loss condition FFA was seen before the appearance of skin depigmentation vitiligo in a patient.

Transplanted transected hair follicles can survive but grow at unsatisfactory rates and are thinner, suggesting limited potential for unlimited donor hair supply.

Hair can regrow in adult mice's skin after injury, and this process can be boosted by increasing Wnt7a, a protein. This could potentially help treat baldness and change our understanding of hair growth.

Hair follicles are key to treating vitiligo and alopecia areata, but challenges exist.

Adding nano fat to hair transplants improves results for scar-related hair loss.

Milia may come from the outer part of the hair follicle.
