WOW………amazing hair !!! Never colour it please !! I am a hairstylist and feel sick when someone with hair like this wants blond highlights. If this is not natural, you have the best colourist in the world. Beautiful.
Its hair color. Look at her roots which are lighter then the rest. I die my hair this same color, and know exactly how it works out. real redhair is much more orange, and of course all real hair is darker at the roots where the sun hasn’t had a chance to lighten it. But when you touch up your roots you get a slightly lighter and brighter color at the root. It would be obvious to a colorist. I am sure she is blond naturally, because she is using eyebrow pencil, but still you can see it..
