Androgenetic alopecia (AGA) is a medical condition that causes hair loss at the scalp. Alternatively called male pattern baldness, this condition is most likely to impact individuals with a genetic predisposition. A variety of environmental factors have also been attributed to this type of hair loss.
With AGA, hair loss often occurs in an ‘M’-shaped pattern spanning the crown but can also present as thinning at the temples or general loss of volume across the scalp.
