partial or complete loss of hair from the scalp
Scalp hair loss, also known as alopecia on the scalp, refers to the partial or complete loss of hair from the scalp. This condition can result from various factors, including genetics (such as in androgenetic alopecia), autoimmune disorders (like alopecia areata), hormonal changes, medical treatments, or nutritional deficiencies. It can manifest in different patterns, such as diffuse thinning, patchy bald spots, or complete baldness, and may require different diagnostic and treatment approaches depending on the underlying cause.
