Can a vitamin deficiency really cause hair loss?

No. No particualar vitamin associated with hair growth/loss, even though some advocate that biotin in large dose would help hair growth. Poor nutrition (so, vitamin deficiency as a consequence) would lead to hair loss.

I am 20 year old I started losing hair more frequently in february can the be because of stress or vitamin deficiency or over use of hair putty?

I hope this helps. Read more...
