I'm finally the OP...
My hair is fine, straight and there's not a huge amount of it. Straightening it generally enhances how there's not an awful lot of it, as does putting it up in a ponytail.
My aim would be for it to be shiny, smooth, silky, preferably not entirely flat to my head.
As it is so fine, it could ideally be washed every day but I tend to wash it every other day in the week to try and save the condition.
At the moment, it is a couple of inches past my collar bone but the ends go quite fluffy. I am very nearly at the stage of having no dye on it as I don't think this helps - it's a sort of unintentional ombre but it doesn't look too bad condition.
So... please share your tips!
