Alopecia areata is likely an autoimmune disease with unclear triggers, involving various immune cells and molecules, and currently has no cure.

Researchers created human hair follicles using a new method that could help treat hair loss.

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

ATP-dependent chromatin-remodeling complexes are crucial for gene regulation, cell differentiation, and organ development in mammals.

Regenerated fully functional hair follicles using stem cells, with potential for hair regrowth therapy.

Erectile dysfunction is increasingly common in men under 40, with many physical and psychological causes, and various treatment options available.

Bone Morphogenetic Proteins (BMPs) help control skin health, hair growth, and color, and could potentially be used to treat skin and hair disorders.

The conclusion is that accurate diagnosis of different types of hair loss requires good teamwork between skin doctors and lab experts.
