Does not work, AWFUL product 

To cut it short, this hair dye does not work. I have pretty much white blond bleached hair, and after my half pink half silver hair washed out, I wanted to go rose gold. This is the only one I saw so I picked up 2 boxes (£11 in Superdrug for both) got home, washed my hair with shampoo, towel dryer it and put on the dye, it said leave for 15-20 mins but I left it for a full hour as I REALLY wanted that pay off, washed it off, used the provided conditioner and NOTHING. my hair was EXACTLY the same. Not a single hair was ‘rose gold’. So I used the second box the next day, STILL NOTHING!!! A waste of time, energy and money. I used crazy colour rose gold instead and worked a treat.  Overall just very disappointed in this but if you go on the boots website and look at the reviews they’re all 1 star so there you have it
