Scott Cornwall Decolour Hair Colour Remover

Works well! I have extremely thick hair , that had years of built up colour in it (red).I followed the instructions, and left it on for 45ish mins, it removed majority of the unwanted colour. I left it for a few weeks and did it again and all unwanted colour is now gone! The smell that everyone has mentioned isn’t bad- sure, a slight smell, but not what they’re saying- they’re really over exaggerating! It Left my hair soft and undamaged! So easy to do yourself! Highly recommend!!

Don’t do a thing and smells horrible. Waited 25 minutes, no difference and still smells horrible. Washed my hair 5-6 times, smell doesn’t go anywhere

The smell of this product is awful. I couldnt leave it in for longer than 10mins, it smells like sulphur laced farts mixed with a hint of sickly sweet fruit. Would not recommend

Bought the product but not worth buying as it didnt work at all on my blue color.not removed evan a bit..

Smells awful but works really well on box dye. Left my hair really soft and shiny. Highly recommended, especially on dark hair. It lifts it with no brassiness.

So bad did nothing at all I followed all instructions did my research on this product first and it did litterally nothing but make my hair smell and feel dry

This stuff reeks like 10 different types of ace but it works. If you have long or thick hair I’d recommend buying a couple boxes :)

I bought this online to lighten the flat colour of my hair. It worked well, really straight forward instructions. Happy I took a chance lightening my own hair.

Absolutely awful smell. Has not lifted a single molecule of colour off my dark brown dyed hair and now I am left with this rotten egg smell that I cannot get rid of and there is NO RESULT! Hate this product!

I have maximum 2 layers of dark brown dye in my hair, which is naturally a light brown/dark blonde. Used this product twice as per instruction booklet and it didn't do literally anything for the colour, but now my hair is dry and stinks like rotten eggs. I can't use the Colour Stripper either because I have an anaphylactic allergy to something in hair bleach, which is likely in the Stripper too since it smells the same. Do NOT recommend.
