How can I dye my auburn red hair a light brown?

If you add a few drops of UNRED to the dye before applying it will cancel the red tones that would normally come up... A great product! Hope you'll give it a try... available on Amazon and at Sallys and at folica.com...and plenty of other places i am sure:) You could also just use the light brown dye you have chosen, and then buy a toner to add afterward that has a BLUE base(which will cancel the orange tones)...Hope this helps! Good Luck!
