“Hypertrichosis is the term used to describe excessive hair in both men and women that follows normal hair patterns. In plain language, if a woman has a lot of hair on her legs or a man has a lot of hair on his back, they are considered to be affected by hypertrichosis. This condition does not refer to excessive hair on unexpected parts of the body (on women’s chests or on ears, for example).”

WRONG! Hypertrichosis refers to excess hair growth in areas that are not affected by androgens (for instance the forehead), which is its distinguishing feature compared with hirsutism. You need to clarify the difference with an actual medical professional.
