Scott Cornwall Decolour Hair Colour Stripper with 6% Peroxide, Ammonia-Free Lightener for Natural and Artificial Colour, Vegan Formula, 9 ml

My hair is naturally grey, mostly brilliant white at the front, with more peppery brown underneath, at the back. The first photo shows my hair after four years of fortnightly henna: a few weeks of Lush henna, with a bit of indigo that shows up in the ends, followed by years of supposedly pure, organic henna. That was fine until batches of it contained PPD, which I am allergic to, the reason I started using henna in the first place. After that, I started getting sensitivity to henna that actually was pure, so I had to stop using it. I read all the press which says you can't strip henna, you have to cut it off, and threatened melting hair. I thought, if I’ve got to cut it off anyway, I might as well see if I can strip it - if it’s a disaster, I’ll cut it off. I’ve used Colour B4 on dark hair in the past, which left my hair brilliant orange, so I thought I would try Scott Cornwall products this time. I did two strand tests, leaving the product on for 2 hours, the maximum active time mentioned on the boxes. The Declour Remover (red box) did nothing at all, but the Decolour Stripper (blue box) took the strand to about 2/3 of the way between 10/03 and 10/04 on the Koleston Perfect colour chart. So I tried a skin patch test and got no reaction and decided to go ahead with the Decolour Stripper. The way I did it wasn’t ideal, because I didn’t use enough at first and left it on too long. So my recommendation, if you are going to try it, is to use two boxes unless your hair is very short, and to do a strand test at the same time, so that you can see exactly what the colour has become from the strand and don’t need to mess about uncovering and checking your head. Anyway, I can’t show you exactly what my hair looked like afterwards, because I used toner on it straight away, so my after picture has a bit more yellow in it (Wella Gold toner) than it had immediately after stripping. But it gives you an idea. I wouldn’t dare use peroxide on my hair, in case it really does melt! but I’m now very happy playing about with different semi permanent toners, which give me highlights and a slightly different colour every wash. I wish I had tried it years ago!

This product was amazing. One day I thought again to myself why not changing hair colours? Got bored of purple and blue split dye, couldn't really keep up with it and it was annoying after while. First had the wrong colour remover and read the instructions. Needed to change to this blue box here. Since it is for fashion colours like pink, blue, purple etc., I was confident it would turn out somewhat good. Darn, it totally melted all the blue and purple out of my hair. My hair was not damaged, in fact it feels soft and healthy. The icy blonde you see is from pre bleaching in order to make the blue pop. These ends are on the dry side but easily fixable with deep treatment like I did. After I applied the remover I had numerous shades of blonde, but I was not mad at it. It applied easily and no horrible smell occured. Dyed it red anyway, so the shades of blondes were more than enough for my purpose. I love that products like this exist, I really needed a change in hair colour. If you are camelion like me: get this, blonde up and apply your new colour right after. But please do not fry your hair off by changing hair colours like your underwear. I wanted a change after 1 year, which was a long time in between. I badly wanted to just apply one hair colour and be done with it. Instead of applying two colours. I need to re-7apply the red again, first dyeing is of course always there to put back pigments into the hair. Second dye will restore somewhat the bonds and the colour will be deeper. And always (please!) use a good conditioner and/or hair mask. Wait with the second dye one or two weeks. Let your hair relax a little and practice patience. Love your hair, it will love you back. And don't forget to love yourself for who you are. You are great! I am fully happy with my transition back to red and never thought I can make that happen in just one day. I recommend the colour remover (stripper).

Scott cornwall, count your days! I have pretty thick hair, but this absolutely destroyed it, i followed it exactly and was taking off red hair dye on blonde hair, but oh my god! I have never had so much hair fall out, my hair is so so thin now, i only did one round of this product but i can’t believe how much it has destroyed my hair, my hair was super healthy before and now it’s so dry and horrible, it feels like wire and it’s lost so much thickness. Edit, After i had a shower a larger amount than the photo fell out, i have multiple chunks of hair missing at about a 6 inch length, my hair was triple that, now i am lucky as i have thick hair so in certain hair styles i can hide it but i just want this to be a warning to others who might have thinner hair, Please save yourself the pain and go to a professional and do not use this product!

I want to start by saying, try to ignore these really negative comments. People who are saying it didn't work ATALL, clearly didn't use it right..It absolutely does work. As it says on the front, it is a colour stripper AND bleach lightener, your hair is NOT going to go perfect blonde, with any box hair product that should be obvious..I had a medium red on my hair before using, and now my hair is VERY light yellowy orange, which of course I expected due to the bleach, red is HARD to get rid of too, so expect there to be a reddy residue. If your hair is DARK, you will probably get a murky orange with yellowish roots.. I did what it was suppose to do, it stripped my hair of the bulk of the red, and lightened it, ready for me to dye again.. If you expect perfect unpatchy hair from a box product, you're absolutely delusional..ALSO some people have multiple dyes on their hair, meaning mass build up of colorant, meaning you may need to do this twice to see more extreme results..It works fine, it did what it said it would do. Is my hair a little dry and slightly damaged? Of course it is..Its a box stripper with bleach in it lmao..I'd be shocked if it wasn't. Some people's reviews blow my mind 🤣🤣

I gave 3 stars because this product is not strong enough to build up dark dye hair. It was just gently lighter, but I am still unable to put very light shades. After this, from dark brown, I go to mid brown. The Positive is that this is not damaging your hair

Changing my review because the packaging was strange and half the things weren't in the box but were in the packaging itself? Strange. Anyway great product but loong instructions but if you follow them it will give you the results. Doesn't leave a smell but there is a strong peroxide hit initially using it. Hair was surprisingly left in a good condition (as good as a condition as you can hope for after stripping it)

okay so I am totally obsessed w this product!!! I totally forgot to take pics after before I toned it but you guys just have to take my word for it. I bleached my ends and than put 'medium ash blond on it' to get the orange out and OMG I hated it so much it was so dark and grey and it looked dirty it was the worst colour on me, wow - so I used this to strip it back which it did most amazing job (it was even lighter than before!!! but pretty yellow again- more than it was before I put the medium ash blond permanent colour because I used some toning purple conditioners and stuff after I bleached it the first time...) btw after I toned it w the well T18toner and now its amazing exactly what I wanted :] BUT I get why some reviews are not great and here is my take on it: - yeah it gets really thick and its a nightmare to get it out of that bottle!!! if I need it again and will buy it again I will take it out on regular bowl and mix it in there w the brush!!!! I did manage to take everything out but I had to shake it out hardcore, unscrew the tip off and just shake it out - I'm pretty sure some ppl thought it was finished before it was actually finished I was pretty amazed too that something still come out over and over again! - I used the entire thing and I needed only on like 4-5 inches of my ends of my hair, so yeah if I was doing the entire head I would definitely buy at least two esp if I had really thick hair - instructions - I mean my English suxs but yeah it could have been more straight forward it's not the best but you guys my hair was definitely NOT damaged at all - and I bleached it prior two times and coloured it that medium ash blond crap - (even tho before this I started with super shinny silky natural dark brown hair without one split end.... I haven't done anything to my hair in like 6 years) it smells great I could not believe things I read about the other products it was super scary - like it didn't come out after 8 washes!! and it is well priced. I definitely would recommend it to all my friends :] xo

Worked a charm. Would buy again

I followed the instructions exactly and it didn't lift anything at all. really disappointing. Use Colourless instead it works perfectly every time

Ich hatte den entfärber bereits einmal erfolgreich getestet, habe dann ein zweites Mal bestellt (2 Packungen) habe nur eine erhalten. Darüber hinaus war dann diese Packung nicht vollständig. Es fehlt das Pre Treatment. Ich bin enttäuscht

I used this product this morning, and it Does Not work at all as described. My hair is about a shade lighter and appears highlighted, not color removed. It doesn't perform as advertised. Very messy to mix, tiny bottle doesn't cover your hair unless it's about 2' long, and extremely difficult to spread evenly through hair. Use L'Oreal or OOPS, and leave this crap on the shelf.
