Review: The color I want is impossible to find - This is a fabulous product that had my hair looking like sunlit beauty. Yes this is a professional product that I just can not find anymore. Where have all the blondes gone in liquid form? There are no more blonde good color anymore. It's as if we have been wiped off the planet. Everything is for dark haired people. We are now the forgotten people. Sad. Thanks ION for removing me and people of my coloring from the world of beauty. I will not forget.
Review: Beautiful and easy to apply - I loved this dye. 8RC (Light Copper Blonde) leaves a very vibrant and luminous tone, just what I was looking for. The formula is creamy, easy to apply, and doesn't have as strong a scent as other brands. I liked that it left my hair soft, shiny, and without that dry feeling after the process. The color was very true to its promise: an intense yet natural copper, ideal if you're looking for a striking change without going overboard.

## Questions & Answers

**Q: I'm using 5nn to cover a box color that came out very copper instead of light brown. I'm 30% gray. Will a 10 volume developer be enough?**
A: I didnt find the 10 help that much. My gray is so resistent I use it with 20 developer also added gray magic to give it extra boost covered great.

**Q: I bought 4A medium ash brown and 4N medium brown, I have dark brown hair with multiple warm highlights. will this cover my highlights but not turn red**
A: not sure, I bought 8n made my hair gold. I'm a dishwater blonde.

**Q: Do i need to buy a separate developer? which one for ash brown over highlights? want brown not red**
A: salon care volume 20 creme. I don't know about the highlights but this color can be a light brown or a little darker if Yo u leave it on longer.

**Q: So which one of these will give you the lightest blonde?**
A: I use this with a 40 volume developer for a high-lift. It lifts really well and is extremely conditioning, giving a super, shiny, finish. Hope that helps.
