Hi everyone, I am posting on this forum in order to help some of you, I have sufferred from hair loss for approx two years. i was losing lots of hairs a day and double that after a shower. I started researching different reasons for hair loss online and came across a few articles about hair loss, the one that stood out was vitamin d deficiency. I went to the doctor and was tested for vitamin D deficiency, sure enough I was extremely low.My doctor started me on vitamin d supplements and within 4 weeks my hair stopped falling out! I would suggest anyone experiencing hair loss or thinning should get their vit d levels checked at the doctors, and hopefully like me, your hair loss can also be stopped if that is the cause.
