Does anyone know anything about dyeing hair? (UK)

I bought the real hair extensions from Sallys and whenever I dyed them I used box dye. I took them from blonde to dark brown and back again and the box kind worked just fine.

Boots sells bleach.

I've used them both on my hair but not sure how they'll work on extensions. x

I've used Live Colour bleach on my hair before, I got it for about £4 from Savers and it took my hair from dyed jet black (my natural colour is dark brown) to strawberry blonde

You need to use bleach and a high developer (20, 30 or 40, depending on how light you want them).. you can't lighten already colored hair with just regular hair color- it has to be bleach. You'll have to lighten it to the 'level' that you want it, and then end up toning it to the shade that you need- that's where your blue/ purple toner will come in. It happens fast, so be careful- you don't want to end up with lavender hair!

The two things mixed together to make hair bleach are usually a blue colored powder which is called powder bleach or 'hi lift' or something else, the liquid is developer which comes in different strengths called volumes or 'vol' on the bottle, 5 vol developer is the weakest and 40 vol is the strongest.

The reason the extensions came out a different color is because everyone's hair lightens at different speeds and as its not your natural hair it is not going to bleach at the same rate. You will either need a hairdresser or friend to help you apply the bleach to only the extensions... I would go to a hairdresser to be on the safe side but if you can't afford it that Just do a lot of research online first - there are a ton of websites and videos on bleaching hair at home.

You might need a toner too.

Sorry I thought they were on your head not clip ins. You can do it yourself then! good luck

HELP!

Over the last few months I've had hightlights lots of times and I'm now pretty much blonde. The problem is, my clip-in hair extensions are still a caramel type colour. I've tried dyeing them with 2 different dyes that have promised to lift your colour up to 6 shades ... I'll be lucky if they've went up one!
So I think I need to bleach them. Can I only buy this from Sally's or Salon Services? Also, what do I buy (as stupid as that sounds!) as I know when the hairdresser bleaches my hair with that bluey/purpley stuff that she mixed up, she puts 2 ingredients in. What are these?!

Most likely the colour never lifted because when they were manufactured they had a hair colour placed on them that got them to the colour they are now. You cannot, now put a colour onto another colour and want it to go lighter, colour on colour does not lighter, you can only tone or darken with dye.

You will need to bleach, 30 vol peroxide mix with the bleach powder to a creamy consistency, here is where it gets tricky, you need to get that bleach on bloody quickly, because if you do not, the bit you have done first will be bleaching (the molecules will be breaking down during this process) and you will still, frantically be trying to paste the bleach mixture onto the rest of the hair.

When it is all pasted with bleach mixture, you should time it from there - continually checking that it is lifting to ABOVE the shade you want (this is so when you put the toning colour on, it will work), however, that first bit you did that would most likely be a white by now...... watch it isn't breaking off.....

If you are lucky enough to do all that and still have the hair intact, you will need to put on a toner of your desired colour.

Or alternatively, you could do as another posted suggested and buy extensions that are the same colour as your hair.

Hello. I am a hairdresser, have been for thirty years. Those two ingredients are color and peroxide ( they call it developer these days - it sounds better for your hair, but it's just peroxide) You will need to pick out the color you want at Sally's, but make sure the level of lightness is what you have been getting at the salon. You look about a level 7 or 8, but it's hard without seeing you up close in person. First, find the colors that are the right level, then choose a shade from that that is closest to what you want. Mix equal parts of the developer (40 volume) and the color. The instructions will be on the color bottle. Any color in Sally's will do.

You must "watch" the color. After about 20 or 30 minutes, rub off some color and dry with blow dryer (just a little spot) and see how the color is doing. If you haven't reached desired lightness, comb color thru to the dry part and keep lifting until you reach lightness desired. Hope this helps.

Also, by the way, the stuff used on your hair to highlight is too bright to put on a big chunk of hair like extensions. That's why I suggest using color instead of highlight stuff. It will look more natural.

You may do better just buying extensions that are the color of your hair.

How much do the colour and peroxide cost in the UK roughly?

Sorry, I have no idea. I live in the U.S. (Virginia)
