Baldness and alopecia are two terms frequently used in the context of hair loss, but they are not strictly the same as each other.
The term baldness generally refers to male pattern baldness, or androgenetic alopecia.
Alopecia is a broader medical term that characterises any form of hair loss. Alopecia includes several sub-categories such as androgenetic alopecia (male pattern baldness, and female pattern baldness at the margins), alopecia areata (patchy hair loss), alopecia totalis (loss of all hair on the scalp) and alopecia universalis (loss of all body hair).
