Hair colour model

I need an image which I can use/photoshop to show different hair colour for a hair colouring brand. I want a side profile if a woman with shoulder length or longer healthy, thick hair nad the hair needs to be lighter coloured. Background should just be pale grey or white. Woman should just be wearing a black tshirt or similar. Overall styling should be simple, minimal, fresh, modern, not too much make-up and hair should be natural, either straight or with slight waves only, as the purpose of the image will be to showcase different hair colours, so hair needs to be simple, healthy, beautiful.
Thank you.
