Can b12 vitamins cause hair loss?

I've been taking B12 vitamins regularly for a few months now, thinking it's good for my health. However, I've noticed an increase in my hair fall. Could the B12 vitamins themselves be causing this issue?

I love eating chicken and eggs, so my B12 is usually sorted! But honestly, taking B12 vitamins shouldn't cause hair loss. If anything, it actually helps your hair grow. Unless you are skipping meals and just surviving on pills, don't blame the B12!

Bro, B12 vitamins actually stopped my hair fall. My doctor gave them to me because my levels were super low. If your hair is still falling, you might want to check your hard water or maybe you are too stressed about exams like I was.

No, B12 vitamins do not cause hair loss. They are actually very important for healthy hair growth. Please take care and try not to worry too much.

Actually, it is the deficiency of B12 that causes hair fall, yaar, not the vitamins themselves. If you've just started taking the supplements, give it some time. Your hair roots need time to get stronger, so don't stop the tablets in a panic.

Please don't ignore severe hair loss or assume it's just a vitamin reaction. I ignored my thinning hair and fatigue for a year, and it turned out to be a major thyroid problem that got worse. Go to a doctor and get a complete blood test done.

I was just reading a couple of articles on this because my sister had the same doubt. High-dose B12 doesn't cause hair loss, but sometimes a sudden shift in your vitamin levels can trigger a temporary shedding phase. It usually stops on its own soon.

Beta, these vitamins are given by doctors to make your body strong, they won't make your hair fall out. Make sure you are also eating good homemade food and drinking enough water. God bless you, don't worry too much.

Hey, calm down, there is no need to worry. B12 vitamins are completely safe and do not cause hair loss. If you are experiencing sudden shedding, it might just be seasonal or due to some recent stress. Just consult your doctor to be safe.
