About a year ago, I watched in horror as, over a period of about 4 months, globs of hair clung to my hands each time I took a shower. I began to dread the bathing process (not to mention the working out process as brushing my hair into a ponytail left bunches of hair in the brush and also the sleeping process, to wake up each morning to strands of hair on my pillow instead of my head, etc etc etc). I took more vitamins (including hair-specific supplements), ate more protein and good fats, cut out aspartame, got more sleep and even began yoga to relax, thinking it could be stress (which definately can be the case in many instances). But for me, none of these things worked - the hair kept coming out and it got to the point where upon wearing it down, my hair had thinned so much you could see my neck through my hair if looking from behind.
I did some searching on the internet and came across a couple places where it said low iron levels can be to blame. I went to the doctor to have my blood iron levels checked and I was at a 19 count. Normal is somewhere around 30 if I remember what the Dr. Said correctly. As soon as I started taking more iron, my hair quit falling out.
Have you had your iron levels checked recently? If not, I would definately reccommend it. Its super easy to fix and its a very common reason for a lot of women to lose their hair.
