نفس اللون لكن عليكي عمل تشقير بالاول لحتى يزبط اللون ويطلع نفسه.

Definitely not permanenet
This product was very disappointing. At first I achieved the colour of purple I've been searching for for months. It was a wonderful shade, even on dark (dyed) hair. However this was short lived and within 2 washes my grey/white was showing at the roots and the length of my hair had turned a strange washed out pinkish colour. It wasn't cheap, yet it performed worse than any cheaper purple dye I've tried in the past. I will not be purchasing this product again.

I have previously had my hair dyed red by a professional, but being unable to get to a salon again during these times, I took the chance to touch up my hair at home. I also decided I wanted something more orange-red than the dark-red I had. This is definitely a bright orange shade, but after a few washes fades down a bit. I love it and have already ordered again.

I’ve had purple hair since 2018 so I would say I have years of experience with a variety of bright color hair dyes from many different brands. My natural hair color is medium dark brown, but I’ve had gray hair since I was a kid and 30-35% of it is gray. Semi-permanent color doesn’t really cover my grays, so I had to use Ion Permanent Brights in purple for my roots, and ArcticFox for the rest, which after trying MULTIPLE brands, this was the one that worked the best for me. I’d still had to co-wash my hair only once a week to make the color last as long as possible, re-color it once a month, and re-touch my roots every 6-8 weeks depending on growth. I love my purple hair but the maintenance process is exhausting! I NEEDED to find a more permanent solution. I stumbled upon Colour-Plex in Amethyst so I decided to give it a shot. I washed my hair with a clarifying shampoo before applying to get rid off as much of the previous color as possible. First impression: Colour-Flex was very easy to mix, it smelled good, application was smooth, and there was just enough product to fully cover my entire shoulder length thick hair. The recommended processing time is 25 minutes, but I left it on about an hour before washing it with cold water using only conditioner and rinsed it until the water was clear. I have to say that I’m very impressed with the results and I like it so far! Once my hair dried, I noticed that my grays were completely covered and it deposited enough color on the rest of my hair so I didn't need to use a color mask after to get it to the shade I like. The color is a deep purple with blue undertones that looks almost black inside and bright purple in natural light, my hair smells amazing and it is sooo soft! Also, I noticed that my hands and nails weren’t stained after styling it, which is a problem I’ve dealt with my previous method. It might be too soon to tell, but I’ll comeback with an update after wash day.

Tolle Farbe, lässt sich leicht auftragen. Ich hatte vorher schon intensives rot und es nicht mehr zum Frisör geschafft. Ich hab zuerst den Ansatz gefärbt, dann die Spitzen. Es ist schön einheitlich geworden, man sie keinen Unterschied. Bin sehr Happy aktuell! Ich bin gespannt, wie lange die Farbe hält.

El color queda genial. A tener en cuenta: sin una decoloración previa, el tono se va perdiendo con los lavados.
