Only after one wash green faded to blue.
Con Cheap
You get what you pay for. It’s low quality hair dye that damages your hair and the color doesn’t last. This is what people who don’t know any better use or people who are too stupid to look online for quality dyes.
Con Stains everything, color washes out for weeks afterwards
Unless you use proper conditioner sealers.
Con Colors runs when it gets wet
If you have this in your hair when it rains it will run unbelively. Any sort of wetness makes it run even heavy sweat.
Con Dye itself does almost nothing to re-hydrate your hair
When using splat, make sure to follow up with a protein hair mask or using a sulphate-free shampoo.
Con Bleach packet is extremely damaging
Con Fades very quickly
After 3-4 washes the color will leave a little tinge of the old color along with the faded color
