I have just had my hair dyed at the hairdressers and hate the colour. I also had some highlights put through it but they came out way too blonde, and now it looks like I have grey hair!!

I have got a do it yourself dye (the colour I normally use every other time), is it a problem to use this straight away on my hair to fix it? The ends of my hair have just been done with a semi permanent and the roots were done with a permanent.

I have got my wedding next week, and really can't stand my hair!!
