Researchers found new hair and nail genes, how hair reacts to UV, differences in white and pigmented hair growth, nerve changes in alopecia, treatments for baldness and alopecia, a toenail condition linked to a genetic disorder, and that nail fungus is more common in people with psoriasis.

Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

VEGF helps hair grow and determines follicle size by increasing blood vessel growth.

Understanding gene expression in hair follicles can reveal insights into hair growth and disorders.

The document concludes that the hair cycle is a complex process involving growth, regression, and rest phases, regulated by various molecular signals.

Finasteride and minoxidil are effective for hair loss, but continued research is needed for better treatments.

The research shows that a gene called Wnt3 affects hair growth and structure, causing short hair and balding when overactive.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

Future hair loss treatments should aim to extend hair growth, reactivate resting follicles, reverse shrinkage, and possibly create new follicles, with gene therapy showing promise.

Stem cells are crucial for skin repair and new treatments for chronic wounds.

Noggin is necessary to start the hair growth phase in skin after birth.

Certain cells from hair follicles can create new hair and contribute to hair growth when implanted in mice.

Hair follicle dermal stem cells are key for regenerating parts of the hair follicle and determining hair type.
