I want to change my coloured hair from light blonde to medium blonde.?

I have been dyeing my hair a light blonde for a while. I now want to change it to a medium blonde. I have been using an over the counter box colour by Loreal Preference but would like to use a professional hair colour like Koleston perfect this time as I thought it would help improve the condition of my hair. Im just not exactly sure how I should apply a professional hair colour over a colour that I bought over the counter. Should I mix the colour with a 20 vol developer or do I need to use a stronger vol developer? My hair is naturally a medium blonde. As I will have roots should I apply a medium blonde shade to the roots first and then distribute the colour through the rest of the hair for the last few mins (touch up application) or because it is a darker shade and a different brand should I apply the colour to all the hair at the beginning? (as you would with a first time application) Any suggestions would be greatly appreciated!

I think my question here is how did you get your hands on a professional color if you're not a licensed hairdresser??

In either case, I would strongly recommend going to a professional for this and here's the main reason. The boxed color that you have been using contains salts and minerals in it that are now coating your hair. If you try putting a professional product on top of that your hair will likely come out a different shade than what you want it to. In order to get this process done properly you will need to remove everything that the boxed haircolor has put on your hair before you can even think about recoloring it. And the process is not an easy one, for if done incorrectly can severly damage your hair.

As for the case in which you choose to still try and do this on your own, a 10 vol. developer is the strongest that you should use since you're going darker and if you're trying to match the rest of your hair to the roots you shouldn't even touch the roots and let them be. If the color is going to be somewhat different then you should apply the color to the middle of the hair first, then the roots, and then the ends. The roots always process faster because of the body heat. The ends process fast as well because they've gone through the most damage in the past. But I do hope that you choose to go to a salon to get this done properly. Good luck

I think the first thing to do, a few days before you do the color, is do a reconditioning treatment to your hair. This will help put protein back in it and make it healthier. As far as developer, if you are going back to your natural shade, you could even use 10 volume, since 10 justs deposits color and doesn't lift. If you need to lift even a little, you can use 20 volume, but I wouldn't go any higher. As far as application, I would do the roots first, since the other has been previously processed and then pull through the rest of the strand during the last 10 minutes. Hope this helps, and good luck!
