Male pattern baldness is generally identified when hair loss
begins at the temples or the crown of the head.

These areas are the most sensitive to DHT and will eventually progress into more pronounced, noticeable baldness throughout the top of the entire scalp.
There are two commonly used female hair loss density scales used by most hair loss specialists; the Ludwig Scale and the Salvin Scale. Both scales are virtually identical, however, the major difference is the Salvin scale also measures thinning.
