Knight & WilsonColour-Freedom 150ml Truly Blue Semi-Permanent Hair Colour - Ultra-Vibrant Vegan Friendly Colour Mask with Shine Booster Complex - Ammonia Free Colour Lasts Up To 6-10 Washes

So, let's get one thing straight: although this product says "semi-permanent," it’s really not, at least, not on my hair. Once you commit to this blue, you’re in it for the long haul! I was honestly shocked at how long this lasted. Three months, and it's still going strong. Yes, three months! The color has remained ultra-vivid, only really fading at the roots. If you're looking for a true semi-permanent, you might want to think twice before diving into this one. But if you want bold, blue hair that sticks around, this is a winner.The blue is the most vibrant I've ever used, and it’s stayed incredibly bright throughout. I've tried other blue dyes before, and none of them have taken as well as this one did. I think that’s why I'm so amazed, it’s meant to be temporary, but the results are anything but. So, if you're ready to embrace the blue for the foreseeable future, this dye will not disappoint!The application was easy, and the product itself didn't have a harsh smell, which was a relief. Just be prepared to be blue-tiful for a while longer than you might expect. Honestly, I love it, but if you want a short-term fling with blue, you might need to reconsider. This is the long-term relationship of hair dyes.

This stuff is amazing. It smells like bubblegum and leaves hair soft and very conditioned/moisturised. It’s a lush bright blue and makes my hair so shiny. It fades true to tone (shown some pictures. one is one month apart. Please ignore fact poking my tongue out I recently got it pierced and it’s only decent photo I have!) for reference I shampoo once a week and condition 4 times a week. It lasts months. I like to re do it every 2 months but where fades so true to tone it can be left longer. I have tried so many blue dyes even professional ones from my hairdresser and this one is by far the best I have tried! I highly recommend it to anyone!

Amazing it always is the best product compared to loads of others I’ve tried, the other ones always state bright blue and comes out faded and not bright enough compared to colour freedom it’s so bright every single time and such an illuminating colour I love it every single time!!! Thankyou :)

The picture is after 1 week washing everyday and being in salt water everyday. When I first dyed it, it was sonic blue after a week it's this shade of blue, but still looks so vibrant!So I put this dye onto bleached blonde hair.It definitely took alright.The only reason I knocked a star off, is because of the staining. I washed my hair so many times, but the blue kept coming out (it held its colour tho). Even when dry and touching my hair would stain my hands, pillow case, t-shirts and basically anything it touched.

As someone who dyes their hair probably too much, This dye has been in my hair and stayed vibrant as anything since I dyed it in Nov 2022! It’s now almost March 2023 so if you want blue hair that lasts, this is the dye. Smells great, makes your hair feel lush and has amazing coverage. I still have half a bottle and haven’t needed to top up the colour for vibrancy once. Even the hairdressers have been suprised. 10/10 recommend 💕

Keeps my hair super blue. The colour is really strong and bright, and fades really slowly. When bleached my hair is quite yellow so the colour ends up more tealy blue than on the box. One packet is the perfect amount to do my roots and refresh my lengths (my hair is a few inches below my shoulders). Bonus that it smells amazing.

The colour went on easily at first and lasted for many, many washes!However, when it came to removing the colour, it would not budge!We tried several washes using anti dandruff shampoo. Didn't shift!We used a well known hair dye remover kit, it wouldn't budge!!We tried another hair dye remover, it wouldn't budge. The blue changed to a rather fetching green, but would not be acceptable for high school!!So we tried a bleach to lighten it further, but it still remained green! We then applied another hair colour to try ton disguise it, it was still green!So please be aware that if you just want a temporary colour for the holidays, please do not use this one.

This truly does what it says. Just what I wanted! I love the result!
