I don't know anything about how it works, but I assumed it was absorbed by the skin on your head not the actual hair.

I still doubt that putting vitamin whatever on your head everyday will actually make a difference

Yeah but you gotta remember "vitamins" is just a dumbed down term to refer to fats and compounds. It's not actually like food or anything nourishing for the hair. Like a lot of haircare stuff has vitamin e in it, which is supposed to help protect hair from hot blow drying damage and also make it shiny. A lot of the stuff is also moisturizers for your scalp.

I didn't know that. I am definitely going to keep this in mind now.

PH numbers in any hair washing/conditioning product that gets rinsed out.

You end up with the PH of the water, people.

Vitamins yeah that's no good.

Things like fruit, honey, or flowers must be good though right?

I mean, my wife's honey pomegranate and hybiscus body scrub must be amazing with all that fruity yummy stuff.
