Dying a new colour

[Gymnophoria]

My hair used to be "Mystic Violet" (http://www.livecolor.com/products/co...tic-violet-87/) it was pretty dark, but in the right light you could see shades of purple.
The roots started showing pretty bad so last Sunday I decided to dye it again and change the colour to "Red Passion" (http://www.livecolor.com/products/co...ed-passion-43/)

Now my roots are bright red and the rest of my hair looks exactly the same as before. How can I make all of my hair the red colour? Do I just stick to this colour everytime it needs dyed again or do I need to make it a really light colour and then try it or...?
Any advice is appreciated!

You probably have to either bleach or strip your hair since the first color was darker than the new color.

I had this EXACT problem. What i've found is if you use the same brand, but the ones that lighten it as well as colour it. They work really well! They're called Luminance http://www.livecolor.com/products/luminance/

Using the regular ones was also making my hair dark, but since using these (I use http://www.livecolor.com/products/lu...ra-violet-l76/) it's been a LOT brighter

The dye only took to your roots which had grown out. You'll need to either bleach your hair, or strip the color with a product like Color Oops for all of your hair to be the same color.
