Best box dye for greys

[ChIcKeNeLlEn]

I'm sure there must be some that are better than others. I box dye mine copper and have greys.

Don't use semi permanent and fiddle about with the length of time you leave it on. Consider using a few different shades mixed together is my advice.

Oooh that's interesting, never thought to mix a few!

Look into using professional colours and a bottle of developer, easy to do once you get the shade you want and there are so many more shades available. I'm using semis at the moment as my hair is going from dark chestnut to copper again,via bleach baths and at home highlights.

Any brands in particular you would recommend?

@Deargodletitgo oh my gosh! I did this with L'Oreal professional tint and developer and it looks and feels so much better!
