I think a lot of people would be surprised to find how good this is, given it's typically the cheapest permanent hair dye you'll find in store!
I used 03 Ultra Light Sun Blonde for a long period of time and recently switched to 05 Ultra Light Ash Blonde for a change, it blended seamlessly.
I'm always happy with the results and will continue to repurchase this. It love the conditioner that comes with it and wish Revlon would sell it separately it's that good!
I love this hair colour, so much so that I always have a back up supply tucked away incase I can't find it (only a few places sell it in NZ) right now I have 6 boxes of it in the cupboard so I won't run out. It is always affordable, easy to apply, doesn't destroy my hair, isn't too stinky/ have those chemically burn your eyes type of fumes and doesn't particularly stain my skin and if you get any stains from this they usually wash off within a day which most colourings will take a week or so for me to fade away (I always use the darkest shades), the best part for me about this colouring is the shade is the perfect super deep blackest brown (my shade Soft Black) which doesn't look un-natural for my skintone as jet black does and has some warm undertones/hints of brown tones in the sunlight. I have been using this 3 years now and use a box each month or so to touch up the roots. Sometimes it is on sale for $5-6 so I stock up when I can. Definitely the best blackest brown hair colour I have ever found and I just love the after colour conditioner that comes with the pack - it smells divine and reminds me of the Revlon Outrageous hair product line which got discontinued in the early 00's!
