Knight & Wilson Colour-Freedom Truly Blue Ultra Vibrant Semi Permanent Hair Colour Mask. With Shine Booster Complex. Extra Large Tube 150ml. Award Winning Bright Blue Hair Colour.

Avendo i capelli neri prima li ho schiariti, il blu è fantastico, proprio come desideravo! Spero che duri molto, al momento sono veramente felice del risultato appena fatto!

I've dyed my hair for many years and this is definitely a strong dye. looks as advertised on bleached and toned hair and very easy to use. Lost a star as this is the most staining and wash-out I have ever got from a hair dye. I've washed my hair about 5 times now and each time my shower goes completely blue and my hands ears and back are re-dyed all over again. Looks great on hair but makes your skin look hypoxic! would not recommend to beginners.

After years of using Crazy Colour, I decided to give Knight &Wilson a go after a friend recommended it. The Colour is so vibrant and shiny , so much better than Crazy Colour ! I only used 75% of the tube instead of the usual 2x tubes of CC. Easy to use , I prelightened my hair to a light baby blonde ,left the colour on for 30 mins and it certainly did the job. How long it will last I'm yet to discover , however it is so vibrant I have high hopes !

great colour ! stays well even after multiple washes. if you’re looking for a temporary dye, though, i’d avoid. doesn’t stain as bad as manic panic / stargazer / other semi-permanents

Comes out more teal on dark blonde hair. Dyed daughter’s hair for summer. She picked blue , had good reviews. Luckily she loves teal as well. It’s was very pretty but not blue. She has natural dark blonde hair and it was definitely nearer green.
