Hair dye at salon

[wheresthecake]

I had my hair done 2 weeks ago at my usual salon (cut, roots done and 'highlights'-£72) but my grey roots have started to come through already. Is this just the speed my hair grows (normally lasts longer actually) or should I head back to salon and ask for them to be redone!??
Hate confronting hairdressers....

Have a look at the grey all over (or get a friend to do it for you). The regrowth should be exactly the same on all ares of your scalp. If it is, then its just because your hair is growing fast.
