Glossary Hairy Skin

areas with pronounced and dense hair growth

Hairy skin, also known as hirsute skin, refers to areas of the body where hair growth is more pronounced and dense. This can be a normal variation in humans, influenced by genetic, hormonal, and environmental factors, or it can be a symptom of certain medical conditions such as hirsutism, where excessive hair growth occurs in women in a male-pattern distribution due to hormonal imbalances.
