THE WARNING SIGNS OF HORMONAL HAIR LOSS - losing more than 100 hairs a day, thinning at the temples, crown, and vertex. Widening of your part or thinning of your ponytail, scalp becoming visible on top, your hairdresser no longer thins your hair when you have it cut, Itchines, burning, or sores on your scalp, Presence of other hormonal skin changes: persistent acne, increased facial and body hair, Irregular periods, Difficulty controlling weight.

There are three important terms that apply to common forms of female hair loss: androgenic alopecia (AGA, also referred to as androgenetic alopecia); telogen effluvium (TE); and alopecia areata. [...] the cause was not testosterone but falling levels of estrogen.

本书我最认可的大概是医生这种highly individualised cure approach的自觉。We have seen how testosterone, while it is good for bones and for sex, is not so good for skin and hair.
