Customer Reviews
super vibrant and long lasting!
I've used the shades ppl eater, ex girl and stoned pony and they are my favourite hair dyes i have ever used! they are all super vibrant and are the longest lasting semi- permanent dyes I've tried!
Great
Great product, the colour is very bright and long lasting even after several washes
10/10 hair dye
Hands down best brand for vivid colours; the only one that lasts weeks and stays true to tone even as it fades, smells amazing and feels like a hair mask
Amazing 🤩
Highly recommend easily the best semi dye out there , smells amazing and color is so vibrant
My favourite
I will always use this pink for as long as it is available. It is ridiculously pigmented so lasts a long time. I usually like a less vibrant pink so i will dilute it by over half the volume with conditioner and mix well and still looks as bright :) makes hair super soft and smell nice too
Used better!
Very faint even on bleached hair, would recommend manic panic/directions if you're wanting bright colours. Don't rate this for longevity at all.
Ex girl hairdye
This is gorgeous it smells amazing and lasts the colour is so pretty over a light red dye
Excellent colour
Love this colour great when used mixed with conditioner too for a much lighter pink sooo good
Parfait correspond à la couleur
Parfait correspond à la couleur indiqué
Really easy to use for
Really easy to use for touch ups. Have used it twice since colouring my hair pink at a salon in June. Easy application and works well with the dyeposit conditioner. Makes hair super soft and smells fab too!
