I suggest going to a salon and consluting a colorist.  I think reds can be trickey.

Yes, you both are very right.  Reds can be very tricky.  Especially if you already have colored hair.  But I remember very well when I colored my hair red the first time in my whole life when I first started coloring my hair back in the late 1980's.  I used the old Nice N' Easy hair coloring product.  That was before they advanced it into with adding more conditioner to it.  I mean, they had conditioner in the kit but it wasn't as strong as the conditioners that Nice N' Easy has now.  I mean, the conditioner that the coloring kit had back in the 1980's felt like a shampoo/conditioner type solution.  Now in todays more advanced Nice N' Easy products they've made the conditioners more creamy and thicker than before, and I love it very much!!!!  Especially the colorseal conditioning gloss!!!!  I love that conditioner!!!!  I collect a lot of tubes of that stuff!!!  I can admit it that I have a whole small box of that stuff in my closet now.  I can say right now that I have about 60 tubes of Clairol ColorSeal Conditioning Gloss.  It gives my hair a beautiful gloss and shine!!!!  Oh, and I bet it gives auburn or red hair a beautiful healthy shine and gloss!!!!
