I’m not sure if there is such a thing!
I have long hair which for years had blonde highlights. Last year I changed to a balayage which I absolutely love, but the roots and top part are darker than previously, so I’m getting grey coming through a lot more obviously now than I used to. I do use L’Oreal touch-up spray in between but find it makes my scalp a bit itchy. I’m finding the cost and time burden of getting root regrowth done every 6 weeks a bit much now.
I’m a bit reluctant to go back to blonde highlights and wondered if anyone else has come across a viable alternative? I’m not averse to going to the hairdresser, just not quite as often! Going completely grey isn’t what I want to do at the moment.
