Love everything about Garnier products and this is no exception! The no ammonia formula is much kinder to my fine 50+ frequently coloured hair leaving it soft and shiny. It has a lovely consistency and fresh scent when mixed making it non-drip and easy to apply. This colour is tonal and pretty!
I need to use this about every three weeks so I wouldn't say it's permanent. In my view that's a good thing as unlike many other dyes it doesn't seem to build up and leave the ends of my hair darker. I have tried a few brands and for me this is easily the best. It leaves my hair looking shiny and natural. Just try it. I don't think you will be disappointed.
