Best bleach I've used

My hair was about 50 different colours with different shades of blonde and some left over semi permanent dye. This bleach got it all the same colour. Didn't really damage my hair (though somehow my hair is still healthy after 5 years) I've used a lot of bleaches, but the bleach london bleaches are just another level. Would buy more often if I wasn't Dutch making it a little more expensive and if I wasn't inpatient meaning I can't wait for the bleach/dye

It was perfect

Great!!! Made the work, my hair is really dark and I was looking to light up to get a copper on a tinted hair, because aleeady had tint in my hair (not virgin, copper tone from another hairdresser styler), I was not happy the tint just got in the roots and ends, the middle stayed black, so this just help me to work through it, I have to buy some more, to repeat it in a month
