I would get it done properly at the hairdresses & then if you don't like it, colour it yourself to fix it. Which you do by findng a colour that you want, say a med brown. But bfore adding that to your hair add the colour from another packet thats a red based colour to your hair first. So just the colour stuff, don't mix it with the developer. Just add the colour like a "pre rinse" to your hair, don't wash it out & then add your normal colour on top. Thats what I had to do. You have to put the some pigment back into your hair before you recolour over bleached hair.
