So, I had a full head of foils done about 10 weeks ago, to cover up greys. They also helped blend in an old set of highlights that were starting to show through the colour that had been applied to go back to my natural colour (highlights were a bit lighter and I didn't like them".
They were done in three colours (my natural colour and two colours slightly lighter than that) to make it look natural/provide movement.
Anyway, I really like the effect and am really happy. But obviously the roots are coming through a bit and greys are showing again. What do I ask for at my next appointment? A full head of foils? Half head? I'm a bit confused and clueless.
