This site is a great resource! I see that you have answered questions before about Ortho Evra and hair loss, and depression and hair loss. I wanted to know if Yaz (another birth control pill, but with a lower dose of estrogen) can also cause hair loss - and depression/mood swings? My doctor already ruled out thyroid or other conditions as a possible cause. I´m trying to figure out what is causing what.
I would suspect that regardless of the dose of the oral contraceptive, if a woman has a genetic predisposition for hair loss, then the medication would serve to increase the loss. Some medications may have more of an effect than others. On the other hand, Yaz claims to help with Premenstrual Dysphoric Disorder (PMDD), thus decreasing the chance of emotional and/or physical stress which can exacerbate hair loss. As with many medications, there needs to be a balancing act with regards to intended use and benefits versus side effects. With that being said, Yaz (drospirenone and ethinyl estradiol) is known to cause scalp hair loss as a rare side effect — see Drugs.com.
