Hi, I know there are lots of posts about hair fall. I just want to ask that anyone have prolonging hair fall issue. I was having a nice thick long hair when I was in India. Moved to USA 4 years back. I started noticing hair fall in early 2017. Since then I have been to doctors and nothing helps. Been to obgyn,pcp and dermatologist. I am losing a huge bunch of hair everyday. It's like, when I run my finger over,I will get atleast 50 to 60 strands without brushing my hair. I lose 200+ during hair wash. I have changed my water filter too for the shower. Nothing helps. I have vitamin d and iron deficiencies. Taking supplements for that. Vitamin d deficient since 2017. Value didn't increase much even after supplements. 2017 - 11.8 2018- 12.1 2019- 18 2020- yet to check. Taking supplements. I tested iron only in 2019 annual and or read low. Taking supplements on and off since dec 2019. Didn't recheck though. B12- low normal range. Not taking any supplements. Are these 2 deficiencies cause hair fall? One of my friend told me to try biotin any collagen peptides. I haven't tried those yet. Anyone tried that and seen any improvement? I am planning to see a rheumatologist too to check if any autoimmune or lupus. My obgyn said that lupus might cause hair fall. And she tested me for lupus and it was negative. I don't know if it's because of water in usa or any internal issues. It's started only after I move to usa and after 7 months of moving. I even cut my hair to Bob cut now. Because I feel so frustrated with this hair fall issue and seeking a bunch of hair around the house. So did a bob cut. I really need some relief from this hair fall issue. Struggling to get a proper solution.
