Dermoscopy is useful for diagnosing various skin, hair, and nail disorders and can reduce the need for biopsies.

Fibroblasts, cells usually linked to tissue repair, also help regenerate various organs and their ability decreases with age. Turning adult fibroblasts back to a younger state could be a new treatment approach.

The research found two types of calcium in human hair, one that varies among individuals and another that is consistent across people.

The model suggests that scalp tension could lead to hair loss, with factors like blood vessel hardening, enlarged oil glands, and poor microcirculation also playing a role. It also hints at a possible link between skull shape and baldness pattern.

Trichoscopy is a useful tool for diagnosing hair and scalp issues, but doctors must be careful to avoid mistakes.

The normal human prostate does not significantly affect blood DHT levels.

Male faces age with more wrinkles and hair loss, influenced by both body changes and environmental factors.
