I thought someone mentioned more

bacteria being in your hair, but skimming back through the thread I guess not.

But, as much oil that collects in

our hair I personally would atleast assume so.

Alot of people don't wash their hair everyday with shampoo too.

That's aside from the stank folks.

I'd be more surprised if hair was lacking in bacteria.

So that said

i'd wonder if it would be a good idea to shampoo wash before applying to hair.
