I am pregnant and i seem to be losing way more hair than i should be. i have about a quarter of my usual volume and my gynecologist says that she doesnt think that it is related to my pregnancy ?

Some thoughts...: One's primary care doctor can check for medical causes. If none are found, then one can see a dermatologist, especially one specializing in hair loss and restoration. Medical causes may include: hormonal problems (low thyroid), seborrhea, alopecia areata, stressful illness. Other causes: genetic male/female pattern baldness, telogen effluvium, etc...
