I'm 44 and my hair is thinning. My scalp is very dry; it itches & flakes terribly, especially around my hairline, which is also falling out. I don't see the white bulb on the longer strands that fall out. I must wash it 2-3 times a week (b/c of dry, itchy, flakes).'m 44 and my hair is thinning.

Hemoglobin test. Overview. A hemoglobin test measures the amount of hemoglobin in your blood. Hemoglobin is a protein in your red blood cells that carries oxygen to your body's organs and tissues and transports carbon dioxide from your organs and tissues back to your lungs. If a hemoglobin test reveals that your hemoglobin level is lower than normal, it means you have a low red blood cell count (anemia).
Hemoglobin is usually measured as a part of the complete blood count (CBC) test from a blood sample. Several methods exist for measuring hemoglobin, most of which are done currently by automated machines designed to perform different tests on blood. Within the machine, the red blood cells are broken down to get the hemoglobin into a solution. The free hemoglobin is exposed to a chemical containing cyanide which binds tightly with the hemoglobin molecule to form cyanomethemoglobin.
