How can I tell if I'm losing too much hair? Sometimes after I shower the water drain is full of my hair. My boyfriend says we all lose hair, and it only looks for me more because I have black hair.

Your boyfriend is maybe right, it's normal to drop around 100 strands of hair a day. But if you see bald spots, you're taxing your hair or your body somehow.

You may have a vitamin deficiency, a thyroid disorder, or high stress levels. Certain medicines can cause hair loss, including blood thinners, some antidepressants, and acne medications. Or the culprit may be chemical hair treatments like coloring, straightening, or perming. Because there are so many possible causes, you best hair detective is probably a doctor.
