I've got medium cool brown hair with greys, I have a semi permanent brown (6) at the salon which makes the greys bronde which is good as I hate it to look too monotone and fake. But it's still a bit dark. My stylist says as the semi doesn't have any peroxide I can't go lighter but I don't really want to colour my natural brown, I like it! Just semi colour the greys into something that looks like highlights.
Can I go a lighter shade ? Thanks
