Can vitamin b12 deficiency cause hair loss?

I can only share what happened with me, as I am not a professional. Last year my hair was thinning like crazy and I had no energy, and when the doc ran some tests, my B12 was extremely low. Once I finished the prescribed course, my hair fall actually controlled quite a bit.

It definitely impacts hair health, especially for vegetarians like us who don't get enough B12 from normal food. Just go to any local lab and get a basic vitamin profile done, it doesn't cost much. Once you have the report, show it to a local GP who can give you a cheap weekly tablet to fix it easily.

Yes, B12 is crucial for red blood cells which carry oxygen to your hair follicles, so a deficiency directy triggers hair fall. Skip the expensive hair serums and oils for a second. Book a home collection blood test on an app today and get your levels checked first.

Omg same, my hair was falling out in chunks during exams and I thought it was just stress. Turned out my B12 was super low because of all the hostel food. Definitely get it checked, it made a huge difference for me after taking the supplements my doc gave.
