I've been a long-time fan of the Excellence range, but they seem to phase out my colours! I adored the Copper Blonde, and I got so many compliments when I was that colour. When they phased it out I switched to Copper Penny (which was way more red), but I can only find this shade on one of the deal sites. I'm switching to blonde now, using another l'Oreal product (the Mousse Absolute range - I bought a few boxes while I was overseas).
I really like the Excellence range, my colour almost always turns out the way it looks on the box. It doesn't fade as quickly as other brands I've tried.
I have black hair and use Ash Blonde 8.1 to achieve a really nice ashy brown colour. I re-do my roots once a month. This is my go-to hair-dye and is really easy to apply.
