Did you mean Diffuse Unpatterned Alopecia?

Glossary Diffuse Unpatterned Alopecia

Diffuse unpatterned alopecia (DUA) is a form of hair loss characterized by a generalized thinning of hair across the scalp without a distinct pattern or bald patches. It is often associated with various factors, including hormonal changes, stress, nutritional deficiencies, or underlying medical conditions. Unlike androgenetic alopecia, which typically presents with specific patterns of hair loss, DUA results in an overall reduction in hair density, making it crucial for diagnosis and treatment to identify the underlying cause. Key distinguishing characteristics include the absence of scarring and the diffuse nature of hair thinning, affecting both men and women.
