I haven't been taking a multivitamin with my hair vits because the A & D aren't water soluble like say C is. I think I might have to start though. The hair skin and nail vit doesn't have iodine and some things that my multi and the regular hair version has.
This is what I get for switching vitamins grrrrrr

My hair grew 1.5 inch last month. In a week it will be a month since the last measuring and it's grown an inch. Which for me is still fab but I've been shedding more with the vit switch too.

If you feel well with the multi and the hair vits maybe I'll try that.
Low porosity, medium texture.

If it smells good put it in your hair, if it tastes good spit it out!
