for those who have thinning hair and/or hair loss please make sure your blood pressure in in check. Recently I had to call 911 because i thought I was dying. As it turned out my blood pressure was 230/150 and I did not know I had uncontrolled high blood pressure. My hair had fallen out completely in a few different areas a couple of years ago even though I was apl. Now that my blood pressure is under control and I am taking medicine and on a low sodium diet, my hair is growing and growing back very rapidly. This could be the reason that some of us have had bouts of alopecia and other sorts of hair loss.
