I've got a very overgrown balayage (nearly a year old...) but nearly fell over when presented with the bill last time I had it done at the salon.
I'm now wondering whether I can DIY it. The blonde bit I'm fine with, Iused loads of box kits when I was younger but I now have greys so would need to do the top half too in a more natural shade.
I'm fairly gung-ho with DIY stuff like this as I know it grows out eventually but I also don't want my hair to go green.
Is there an order I need to do things ie dark first then blonde or vv? Is it a stupid idea altogether?!
