A member asked:

My hair seems to not be growing anymore, maybe because i have a vitamin d deficiency? would it be ok to take 10000mcg of biotin? im 16, female.

A doctor has provided 1 answer

D deficiency: No biotin - vitamin D 1000 a day is what you need. That said, your hair growth is not well related to vitamin D (biotin) and you should see a Dermatologist.
