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).
Often, the first test used to diagnose anemia is a complete blood count (CBC). The CBC measures many parts of your blood. The test checks your hemoglobin and hematocrit (hee-MAT-oh-crit) levels. Hemoglobin is the iron-rich protein in red blood cells that carries oxygen to the body. Hematocrit is a measure of how much space red blood cells take up in your blood. A low level of hemoglobin or hematocrit is a sign of anemia.
