Better then expectations!
Ive always been one for changing my hair ever since I was young, and this usually consists of trying to reverse the blackest of black hair with a high strength bleach and loosing all my locks in the process! This time round though, and much less spontaneously I decided to look into finding a new way to get rid of my raven black permanent hair color. I went from bleach blonde, to bright red to black about 2 years ago now and had been black ever since (black over black many times), or I should say I've been an array of different types of black also (blue black, purple black etc). My hair now looked totally muddled and unhealthy looking and I felt "washed out" by the depth of the black color on my hair. I thought I would have to put up with it until it grew out! Then I found this product and became intrigued by some positive reviews and also after having watched some before and after videos on the internet I figured I had to try it! Even though I already new that it states it may not work if you have used UV hair dyes such as blue black which I had! I thought it would do nothing... I would like to stress right now (and I can't stress enough!) how important it is to read the instructions very VERY carefully and you MUST read the instructions more then once before you mix the products and start the process! Ive dyed my hair so many times I am so used to skipping instructions and just diving right in, but this product is different and you need to use it absolutely correctly for it to work! Before using the product I washed my hair thoroughly with a deep clensing shampoo (tresemme clense and replenish deep clensing shampoo) twice and no conditioning. As reviews have stated, the product smells bad, but not as bad to me as some reviews have made out! It is some what like egg and something else I can't put my finger on, more chemically! I was worried at first the house might smell for ages after but thankfully it didn't. I got used to the smell quite fast and it didn't bother me much. I wrapped cling film and a towel around my head and made sure I was in a warm place and blew the hairdryer on my head a few times just to make sure my head was nice and warm. Just before rinsing when I took the towel off my head I could already see a change! My hair from the roots looked very light ginger/light brown! The rinsing part is a pain, but you have to time your rinsing to be sure to rinse for 10 minutes between each process (first rinse, buffer rinse and then second buffer rinse) so you do have to put up with about 30 minutes of rinsing but I figured since my hair was so so dark in the first place I had to do it to the max! Even whilst wet I could tell my hair had lost the "blackness" and the tips looked more dark brown/copper colored whilst wet. Then I had the joy of drying my hair to see my hair get lighter and lighter the dryer it got and still in fabulous condition! I was overwhelmed by the results! It certainly didn't get rid of ALL the previous color (as it states you'll never achieve fully natural hair results if you have previously used bleach/hair lightener) but it made my hair a good couple of shades lighter, jet black to copper brown/gingery. The color was also very even to my surprise as I was also concerned the color would look crazy like really light roots and really dark tips but this wasn't the case. I would recommend this product to anyone who is unhappy with their hair and who wants an alternative to bleach! I will be using this product again at some point and I MIGHT use bleach after this but its a relief knowing I can use a much weaker bleach if I want to later on as this product has lightened my hair so well! The only thing I would say is, after my hair was dry my hair didn't smell like the product, but when I used my hair straighteners the smell suddenly came back off my hair which wasn't pleasant but after straightening no one said they could smell anything bad thankfully but be prepared for the smell to maybe linger slightly after using this product.

This works well - worth the time and effort
Update a week or so later, hair appears lighter again than previously (and definitely more than) in pics. Only washed a couple of times since remover was used. Still pleased at condition of hair. Update - 1st wash in and hair still feels fine - but I did pre condition it before just washing the roots (normally just wash roots) Also hair has gone lighter - less red. So I did some research before hand - like not washing your hair for 48-72hrs before using this product and made sure I kept my head wrapped in cling film and a towel turned to help activate the colour remover. I mixed both lots of product really well - for a good minute each time. Rinsed super well too - as instructed. I also used 2 pks as I have a lot of hair. It felt like had enough in it. Hair felt a little dry after the process but I put in a good quality leave in conditioner afterwards - and as I never use heated appliances or hair dryers, that's as good as it'll get. So I did the remover thing yesterday. First signs seemed positive on my wet hair. I've home box dyed my naturally very dark brown hair for years, with various red based colours. The last one being a dark rose violet colour. I'm left with a pleasant smell in my hair today - tbh I don't think the product smells bad - no worse than an ordinary hair dye. Hair feels fine condition wise and I'm planning on not dying at (again as advised) for a while as my hair is naturally porous anyway and the hair shaft needs time to settle. Obviously using red hair dyes that have sneaky peroxide additions in them will have lightened my hair, but the sun also takes colour out my hair anyway in the summer. Taken a few photos and managed to find an older pic (not great but only one I can find!) with hair coloured with the dark rose violet colour. IMO, I think it's done a pretty fair job of removing the colour. I try and not overload colour when dying my hair but invariably i tend to put it on anyhow! As I'm getting more greys, I'm trying to go a little bit lighter brown from my natural colour, to hopefully blend things in a bit - never easy with dark hair! I'll stick with semi or temporary wash in tonal dyes for the moment until I have decided on the colourway I'm going for....Which isnt the end of the world as I only wash my hair 2 - occasionally 3 times a week. DO get enough packets for your hair. I was happy with 2pks, but only because ive recently had more length chopped off. If in doubt get more than you need. DO follow the instructions to the letter. All the bad reviews I read in doing research, obviously cut corners or failed to read the info sheet properly - and read them thoroughly first! DO Use a timer - v important. Keep bathroom and hair warm. Make sure you leave lots of time to do this with no interruptions. I set aside a couple of hours and start to very end was 1.5hrs (product needs 1hr to 'bake') I'll admit I didn't do a patch test(my bad) I'm very allergic to many chemicals and fragrances (as hospital tested etc) etc, happy to say this was a green light for me as a product. No scap irritation or burning etc. Of course please do a patch test yourself! I'm planning on applying a little more leave in conditioner at some point but otherwise my hair feels pretty OK to me, not as dry as I feared. Would I use again? Yes I would. Am I pleased with the results? Yes I am, the end result colour was what I was expecting (re info sheet!) And I'll live with it for a bit, as dying it again too soon could leave me with very patchy results. Oh and i suffered no hair loss - apart from my usual. Maybe if your hair isn't in great condition - get it into a healthier place so there's minimal damage to your hair. Before photo is the mirror one, the one with wet hair is after rinsing thoroughly. The after photo is one with a blue face and an orange top. To match my hair...😉😂

Only worked BEFORE the first rinse.
Product was a complete wash out (literally). I've been dying my hair dark brown (Nice 'n Easy, Dark brown foam by Clairol) for the past three or so years and thought it was time for a change. I wanted to go back to my natural colour (which is pretty much the same colour as the model on the packet). I did my research and everyone seemed to agree it worked. I was perfectly willing even for my hair to turn ginger (for then it'd just be a case of a light bleaching and toner to get it back to something nearly my own shade). Nothing I could find indicated that I would run into the problem I did; the product promised to deliver at least a partial stripping of the brown. The promise didn't deliver. I bought my first packet from a supermarket, and used it. Followed every instruction to the absolute letter; before I rinsed I noted my hair looked lighter as if it were turning ginger. I was impressed and hopeful. And so, I rinsed. However for some reason, using the buffer turned my hair to a ginger brown. Fine, I thought, no problem. I'd been prepared for this. What I wasn't prepared for was what happened the next day. The next morning, I awakened and went to brush my hair to find that miraculously it is...dark brown? My ROOTS are lighter, which is the natural colour of course but that's only about a couple of centimetres worth of dark blonde, the rest is the colour it was before I'd started. FINE, I thought again, clearly even though my hair is short, there just wasn't enough of the product. I will use another application. So I ordered from Amazon. Did another application, the same again, hair looked like it was turning ginger, and then, rinse, buffer, rinse again, magic, hair goes that strange darker browny ginger. After this I suspect actually that the BUFFER was somehow the problem. Two days later, I look in the mirror to find my hair is dark brown again. Seriously? Two packets of their product, I've just paid £22 and am out of pocket to look the same as I did before I tried the foul smelling stuff. I realise every person is different and uses different products, etc, so I tried to contact them to ask advice on what I could do and what would have caused it to happen. Not so much as a courtesy reply. Nothing. No explanation, no kind suggestions of what I could do to rectify it. Not a sausage. I know not everyone will have the desired results, but not even a reply to say that they were sorry and that 'this' or 'that' could be the cause, no trying to give reasons like the brand of dye I'd used, etc. Not even an excuse? The lack of communication left me feeling very cheated. I really wanted this to work, but wished I'd just stuck another £70 onto the balance and gone and get it professionally stripped). £22 and now the only option I have is either to cut my hair down to the blonde roots or to let it grow out and cut off the brown, either way, no thanks Colour B4. In my personal opinion I'd suggest either waiting until it goes down to a ridiculous price (like half off) or that you only use it if you're the kind of person who has only dyed their hair once or twice before. I don't think this is really meant for people who have persistently abused their hair with dye (although they don't state this on the box or they wouldn't have been able to sell it). Very disappointing. EDIT: Just to note to people considering buying this product...I have tried nine separate times to get in touch with the company behind this product via email and every single email has been ignored. Completely unacceptable. This company DO NOT CARE. Avoid at all COSTS.

Works very well! Time consuming, but worth it.
I accidentally dyed my hair black last autumn when trying to color a dark brown color. It looked just awful and since I have skin on the pale side, it was very unflattering. The salon told me they could help me with some 'light' bleaching, but I'd had this done once before and remember it fried my hair. So after reading a hundred reviews or so of this product, I decided to try it out. The first round took out a lot of the color (I left it on for 1 hour), but there were still a lot of areas that were still a bit dark (I had only purchased one box and my hair was long). My roots were very ginger and it was very uneven. So I decided to try to immediately color back over it with a light ash brown temporary color. Unfortunately, this was too early and my hair turned completely black again. I was disappointed since the processing took some time and I had been so excited to see my hair less black. So I ordered 2 more boxes and let my hair rest a few weeks before trying again. In between I ended up getting my hair cut and took off about 6-7 inches of the black dull ends that were pretty damaged anyway. The second box removed a lot of dark again, but I had only kept it on 30 minutes so I think I should have left it longer. It was kind of chocolate brown with some ginger streaks, but it was ok. I left it that way for another week. The good news it that after the treatments my hair was lighter and shinier with more body and looked healthier than before the first treatment. So at least my hair seemed to be handling the process without too much visible stress. Today I used a third box and left it on for an hour and finally, the black is completely gone from my hair. It's a light brown color and there is still a bit of a ginger tint, but it's not bad. I'm going to leave it now for another week or so with several shampoos before I try to color again. I'm just trying to get to a very light ash brown color which is closer to my natural hair in the summer. Hopefully with the wait I'll be able to put another color on (again a temporary one) without it turning dark again. I'll be doing a test strand this time just to be sure. So overall, if you're patient, you can get the color out. It depends on your hair and it's history for your own individual result I suppose. As for the smell, well I was expecting something much worse after reading the reviews, but I didn't find it to be anything too horrible. Of course, it doesn't smell like roses, but I threw out the packaging just after the treatment and nothing in my apartment smelled bad. I think the day of the treatment you can smell it faintly on your hair, but by day 2 and after another shampoo, I didn't smell anything and the people around me didn't notice it either. I'd buy this again if I ever have another mishap and I'd definitely recommend it to my friends.

Great stuff!
Worked great. I wanted to get rid of build up. You see I’m really lazy I will put box dye red over box dye red and use different colour reds and so forth. So what ended up happening is the bottom of my hair was darker than the top and completely saturated with colour build up. You can sort of see it in my first photo. Now, I am removing red. I knew that whatever colour was underneath would not be anywhere near my natural colour and would probably be orange or muddy because red hair dye often has bleach in it to make it bright so I knew I would uncover patchy bleached hair which is what I found and is normal. Do not expect it to take off red permanent dye and leave your natural colour, your natural colour is gone bro. Do not panic and try and bleach it. If it is like the first round of mine (the second picture is after using 2 boxes for one round of colour B4) you need another box. What’s left in the first picture is colour build up from multiple box dyes. I used colour b4 again (and only needed 1 box this time as I didn’t go over the yellow at the top) and most of the rest of the build up dropped out. I rinsed it for longer than stated, in fact I rinsed it until I saw the colour stop changing. I would highly recommend doing this for reds. Red clings on for dear life. Also DO NOT skip the buffer. I saw lots of red drop out in the suds of the buffer. I’ve seen a lot of people on YouTube skip the buffer but really don’t especially if you got red. My hair is the perfect palette for a red semi colour now and I’m only going to use semi from now on. You can tell you have colour build up if the ends stay dark, dull, feel heavy and loses its shine. The difference my hair feels is amazing. I did find it dried out a bit but probably because I didn’t use conditioner incase I wanted to do it again. Make sure to shampoo your hair with a clarifying shampoo and again don’t freak out if you see some weird colour when you use it. If you don’t want this to happen, if you don’t want to spend two days with what my teen calls “a hair colour that isn’t a hair colour” then maybe a bleach bath is for you but I didn’t want to do that my hair has been through enough! Hah. Also don’t expect it to be the perfect lightness and even if you’ve been using box dyes. Box dyes are terrible it’s likely going to be a patchy dye underneath. Highly recommend but take like 2 days off for it and get your stuff outside done so you don’t have to go outside looking weird af.

It works
So I tried a different product first before this one and it didn’t work. Then I tried this, worked completely. My hair was practically black and it lifted it completely. To a more light brown ginger colour now. Although it works some things to note - it smells awful. Really chemically smell. And I found I could handle the smell. But it was like there was a very strong after smell that lingered in my house. Took me 2 days to get rid off. Another thing was it made my hair SO dry! As in my whole head was extremely dry, itchy and just driving me crazy. I have experienced extremely dry flaky skin all through my hair now. Something I have never had before. I’ve re washed my hair twice. But I am going to try a hair mask tomorrow. So while I needed to use the product I don’t know if I would recommend it. Just for the afterwards of what happens. But it does work.

It does work
I have dyed and bleached my hair for many many years. I have added bright colours to slices of bleached hair and I have dyed over it to "correct" I have had the infamous khaki effect from colouring bleached hair brown and I have had the over processed ends that are soooo dark they lack any depth of colour. So I took it upon myself to use colourb4 and to honest it didn't expect much because of what I have put my hair through. I applied the product and wrapped in cling film and then waited an hour. I could see after this time that some colour had lifted and I started the rinsing process making sure I followed the instruction times to the letter. My hair felt fine until I added the buffer and then it started to feel very rough and tangled, I continued to rinse but I didn't try to untangle the hair I just let it rinse through. After I had finished the rinse I did add a little conditioner just to the ends and It immediately smoothed out and I could get my fingers through no problem. The colour is admittedly a little brassy and slightly gingery but I did expect this but I have to say that it is evenly stripped and although it is a little darker at the ends it has almost summery highlighted effect to it (I'm thinking Isla Fisher colouring) it looks healthy, it looks natural and it has made me happy. I will probably use a wash in wash out ash blonde colour but only to tone the brassyness out but I'm honestly not in a rush as I don't feel my hair looks too bad. I am fully aware that even dark hair dyes have an element of peroxide to them and this contributes to the gingery effect after stripping but even so I can't fault colourb4 it has done everything it said it would do. I would add that there is an eggy smell to the product but nothing much worse than hair dye produces and it is bearable. All in all I think this product has made my hair look so much better and I am so pleased with the results.

It's magic!!
I have tried to get rid of my very, very dark brown hair to get back to my natural dark blonde for the past 4 months. It's taken me 2 bleaches, one set of highlights, roughly 10 hair dyes and I was still left with absolutely dreadful brassy tone. No ash tone dye or silver shampoo seemed to take off the brassiness, mind you it did tone it down a little. After reading the reviews I was slightly sceptical whether or not this product would work on my previously bleached hair, also the comments about the foul smell turned me off a little. I must admit, this colour remover is the best thing I've used! I absolutely regret not buying this in the first place! I don't really understand what's the big deal about the smell - it's slightly unpleasant but I prefer it to the smell of bleach (or most hair dyes for that matter) any given day. I have long over the shoulder hair and I wrapped my hair in cling film and kept the stuff on for an hour. I religiously followed the guidelines, rinsed my hair for 10 minutes before the buffer and I must admit, my hair was very ginger before applying the buffer (part C). After applying the buffer twice, my roots were a bit gingery but this was stated in the leaflet that came in the pack (apparently bleaching turns your own hair colour ginger) but the ends of my hair were my natural hair colour! I applied silver shampoo and conditioner straight after rinsing out the buffer because I was worried about the brassy tones. My hair turned slightly lighter tone overnight and I dyed my hair with ammonia free dye which was about 2 tones lighter than my own hair and it looks fabulous now! I definitely recommend this to everyone who is desperate to get rid off any unwanted colour or wants to get back to their natural haircolour. Also, another bonus is that it did absolutely no damage to my poor hair. You know how your hair falls out after bleaching it? Nothing of the sort happened with this product, my hair was shiny, not porous or dry whatsoever. It didn't burn my scalp, just took out the dreadful brassiness and left me with the exact colour I wanted.
