The term “androgenetic” was coined by Ludwig (1962), who combined the words “androgen” and “genetic”. In youth, the scalp is covered by thick pigmented terminal hair. Normally, all human beings become progressively balder. The course of androgenetic alopecia (A.a) is progressive in the middle decades of life; the transition into senile involution alopecia follows later in life. A major distinction between long-term normal balding and the condition known as is that the more advanced and obvious signs of pattern baldness appear at an earlier age.
