#baldness

• Alopecia — The partial or total loss of hair from the scalp or other regions of the body, caused by genetic factors, endocrine imbalances, autoimmune diseases, systemic stress, or aggressive medical treatments. This structural pathological phenomenon affects the natural growth cycle of hair follicles, leading to their miniaturization or destruction, and is classified into cicatricial (irreversible) and non-cicatricial forms.
• Androgenetic — Determined or jointly influenced by the action of androgen hormones and hereditary (genetic) factors. In a dermatological and structural context, the term most frequently describes androgenetic alopecia (male or female pattern baldness), a condition characterized by the progressive hair follicle miniaturization under the influence of dihydrotestosterone in genetically predisposed individuals.
