i am a 16 year old female. I have premature graying hair. I heard that vitamin b12 helps restore hair to its natural color. Is this true?
Please help, thanks in advance.
|i find it readily available in all other forms. My mom can't absorb any of the ones that go thru the stomach and the sublingual doesn't seem to do much.
I find sites that require a prescription, veterinary sites, and romanian sites for ordering injectable b12, but none of the common u.S. Vitamin sites seem to sell the injectable version.
Does anyone know of a safe, legitimate way I can purchase this without a prescription?
