androgenetic vs. androgenic
androgenetic:
| • | circulating androgens acting on genetically predisposed hair follicles |
| • | reflects temporary peaks of heightened hormonal changes during: pregnancy (spontaneously reverses), puberty, menopause |
| • | occur slowly beginning in both men and women at age 18-25 but with acute phases of telogen effluvium occurring followed by stable periods of several years |
androgenic: (= hyperandrogenemia)
| • | neoplastic vs. non-neoplastic (ovarian or adrenal) |
| • | drugs that suppress the production of androgen --> metformin |
| • | drugs that block the end organ response --> spironolactone |
Female Complaining of "thinning hair":
(and labs only if the history suggests it will be fruitful)
| • | androgenetic alopecia - family history? |
| • | androgenic alopecia - irregular menses, acne, hirsute? |
| • | telogen effluvium - recent surgery, trauma, procedure? |
| • | medication side effect - examine med list |
| • | thyroid - weight change? GI symptoms? temperature symptoms? mood? |
