[Sticky] Colour B4 Information

I've not done chemistry in a while, but that looks quite different actually from colourb4 ( http://www.tesco.com/groceries/Product/Details/?id=266441865 ). I'd treat it as though it were a bleach product, so wait a week before you do anything else to it other than vegi dye/condition.

ok thank u Ilex 🙂

i think i'll do the first try this afternoon, (and maybe the second if necessary),
and if i have to do a bleach bath i'll wait next week like you said 🙂
(and during the week, coconut oil coconut oil coconut oil^^)

hope it won't be a weird color!

If it has hydrogen peroxide, then it's definitely a colour stripper and not a colour remover, so you need to wait a month after using it before using any other peroxide based product.

But you *can* put a veggie dye in straight after, just no more strippers, permanent dye, bleach or bleach bathing.

hmmm ok thank u.
it's complicated!
and i'm a little bit impatient... :/

That is exactly what I was worried about! I'm glad you checked 🙂

you are like a chemist!
(and i'm watching breaking bad, i'm thinking about hair stuff in the same time xD)

I'm planning my Jo Bazz experiment on Friday night...... i have the FEAR!

So do you recommend a clarifying shampoo before? What about for the next few days?

Hi, I used Colour B4 just before the end of December, then did a bleach bath yesterday (photos and stuff on the thread I started which mentions mint green in the title...) but am wondering whether I should give the Colour B4 another go. I had put purple dye (which came out mostly black) on top of bleached/Midnight Blued ends and an inch or so of roots twice or three times toward the end of last year (I think maybe... late Sept, late Oct and mid Dec?) and my hair's about shoulder length/top layer comes to my ear, so I'd think there should really be some blonde(ish) hair at the ends. The bit from roughly ear down was sort of dirty-blonde/slightly greenish when I first used the Colour B4, and I used a demi-permanent dark blonde over the whole lot a couple of days after Colour B4. But on the red areas, it gets darker toward the ends.

Anyway, tl;dr version: is it worth another application of Colour B4, do you think? I can't really afford to waste the money, but just as importantly, I can't afford to waste the physical energy involved in all that rinsing (disability stuff) if it's likely to make no real difference. I know you can't really tell without a strand test, but any opinions would be really helpful.

Colour B4 isn't designed for semis--some have some luck with it and some don't.  I say if you can't afford it for a second time, don't do it because there's no garauntee it would do anything.

Ah, well, it's more that I think maybe there's still permanent on it, explaining the red? Obv nobody can diagnose over the internet, but is is feasible that what I assumed was my actual underlying colour having gone coppery due to lightening in the perm colourant was actually still colour deposit? (Given that, thinking about it, the ends should have been bleach blonde, probably?)

Ooh, sorry, I misread 🙂

You could try it again, but sometimes the red pigment in darker dyes stain the hair and are difficult to lift out, even with bleach.

Ah, drat! Well, I've bought the Superdrug own brand equivalent thingy, will do a stand test. Trouble is, any hair I could feasibly snip off without it being obvious,  isn't actually red. Was thinking of sectioning off a stand of my fringe and strand testing that...

hey guys i dyed my bleached hair pink a few months ago and now i am letting it fade as i want to go blonde again (hopefully white blonde) and i was wondering if colour b4 works as good on semi permanent dyes as it does on permanent dyes ?

I'm having a hell of a job getting rid of my red dye, Stargazer over a virgin medium brown base. I've lost count of the number of clarifying shampoos I've done, as well as using anti-dandruff shampoo, a cheap version of lime Source shower gel and a mix of clarifying shampoo, lemon juice, lemon washing up liquid and bicarbonate of soda. All in all I must have washed it in one or another of these at least 20 times since dying, and in hot water every time, but it's barely faded beyond the first wash 🙁

I'm thinking now of trying Colour B4, but what are the chances of this working after a lot of force fading attempts? This is going to be a really expensive waste if I try it and it doesn't work 🙁 I should mention also that I left the dye to develop for 10 hours and I think I read on here that veggie reds can sometimes permanently stain the hair, but is this only when applied to a bleached base or can it also permanently stain virgin hair? I'm really frustrated because I just want the dye gone now and my virgin hair back 🙁 Having read that veggie dyes wash out of hair completely after 5 or 6 washes, leaving no trace, I am quite stumped as to why it's clinging so stubbornly, if not for the length of time I left it on...

As stated earlier on this page of the thread, Colour B4 is not designed for semi dyes.  Some have luck with it, some don't, but it's a crapshoot.  A lot of people have had decent luck with Scott Cornwall's Decolour Remover lifting semis, though.  Be aware that pinks are *really* sticky (and some basically fuse to your hair and will never fully lift out), so your dreams of going platinum might have to wait until you grow out the pink.

I've never a veggie red stain my roots, so I'm stumped as well.  The only thing I can think of is if there's a bit of weathering along your hair which made a little bit of a rough surface for the dye to grab on to?  Try Scott Cornwall's Decolour Remover; a lot of people have had luck with that and veggie dyes.
