Glossary Aromatase

enzyme converting androgens into estrogens

Aromatase is an enzyme that converts androgens (male hormones) into estrogens (female hormones). This process is crucial for maintaining the balance of sex hormones in both men and women, and it plays a significant role in various biological functions, including reproductive health and bone growth. In the context of hair, aromatase activity can influence hair growth patterns and conditions like alopecia.
