Mid-back length hair. Originally dark brown and very shiny. These days, it's a mix of my uneven natural greys, and a combo of (super expensive) lowlights and highlights by a very experienced and well regarded colourist.
So the colour isn't an issue - the colour I like, but the condition is awful. My hair is very fine (but there's quite a lot of it) and it just never looks smooth, always ends up a dry.fluff, even when dried and straightened using a selection of products.
Please advise me - what actually works for restoring sleek shininess?
