Hello doctor. i would like to know what is the best treatment for a hair loos problem for a woman of 48 years old?

Hormonal problem: You need to find out what is causing your problem. 2 things that come to mind immediately are hypothyroidism and high levels of testosterone, each of which are very common (and commonly underdiagnosed) and can lead to hair loss. Have your doc run some labs thoroughly checking for these problems. Tsh, free t3, (liothyronine) free t4, total t3, (liothyronine) total t4, tpo ab, shbg, estradio, testosterone, insulin, progesterone.

Hair loss: The most important thing is to find out the reason for the hair loss. Different conditions would require different treatments. See your doctor to get a diagnosis. Something that could help in the meantime would be enough protein in the diet and to take biotin, which is a vitamin that helps the skin and nails and hair.
