I know it's one of the first things that is checked when we see a doc for hair loss.. if you haven't had blood work yet, DO IT. I have low ferritin levels and have been religiously taking iron pills 2 times/day and eating red meat almost every day... now when i shower it is nowhere near the 300+ hairs in the drain, it is much closer to normal. I still have super thin hair (as i have my whole life) but am no longer actively losing it.. my hair still looks like sh*t of course, but now i have learned to conceal my scalp better and wash it only 2 times a week. And occasionally i *do* actually have a good hair day! The iron absorption is tricky, having to work coffee/dairy around when i take the pill/have red meat.. but i can feel my body getting better, almost like a high after i eat a burger. The hair shedding was a sign that my body was severely lacking in an essential nutrient.. i probably never would've had my blood checked if the hair loss hadn't propelled me into the doctor's office. I also had severe fatigue and heart palpitations which i presumed just went along with having a very stressful life with young children. In a way my hair loss might have saved me from permanently damaging my body in a more serious way.. even though the agony of seeing it all go down the drain or sprinkled all over the house felt worse than anything, short of death. Get that blood work if you haven't.. hope to see regrowth in several months, but i don't really care as long as the shedding has STOPPED.
