A member asked:

Which vitamin deficiency can cause hairloss?

A doctor has provided 1 answer

Why do you ask?: Nowadays, vitamin deficiency is only a rare cause of hair loss. If you make this assumption based on a charlatan's website, you'll end up buying something that won't work, and if you complain, you'll be told it was your fault. Biotin deficiency sufficient to cause hair loss is hard to get. Get with a competent physician if hair loss is a concern.
