Male pattern baldness involves genetics, hormones, and needs better treatments.

Alopecia areata causes hair loss, has no cure, and various treatments exist.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

Estrogens help reduce skin aging, and SERMs might offer similar benefits without the risks of hormone therapy.

Potassium channel openers are effective in treating heart conditions, high blood pressure, pulmonary diseases, bladder issues, and hair loss, but more selective drugs are needed.

The article concludes that the wool follicle is a valuable model for studying tissue interactions and has potential for genetic improvements in wool production.

To diagnose hair loss, use a systematic approach including history, exams, and tests.

Hormonal treatments can help with acne, especially in women, by lowering androgen levels or blocking their effects.

Hormones, especially androgens, play a key role in acne, which can be a symptom of systemic diseases like PCOS and may require targeted treatment.
