Box dye color

You can use a lower vol developer (I always use my own so i know exactly what strength it is) but you may not get the result expected, so always strand test first.
20 vol is still going to lift, you want 10 vol or even lower to make it into a deposit only dye
You can't substitute conditioner for developer

Thank you for that.

I really like the box dye its ash blonde/pearl but I expect it will have 30 or 40 vol developer in it, if I put 10 vol would I leave for the full time or half it just for a colour deposit.

****  just seen a tube color, Wella Koleston Perfect Special Pearl Ash Blonde 12/81 - 60ml
could I use 10 or 20 vol with that, and do they give an instruction of how much developer to use?

Thanks again, you have been a big help.

I don't know what vol is recommended for the Koleston, you would have to ask at Sallys or ring the manufacturers, professional products don't always come with instructions.

You won't get the colour on the box, lowering the developer is likely to give  a darker result, so always strand test.
TBH you will be better with a demi (28 wash) dye, (rather than a permanent) they work really well with lower vols of peroxide
What colour is your hair now, and what are you trying to achieve?

Im sure I read that the box dye was only 28 washes, even though it says permanent. I dont think it tells you what the developer is.

Where would I buy demi 28 wash??

Thanks

Box dyes that are labelled semi permanent or ammonia free. Or go to a sallys and ask for demipermanents

The formulation instructions say to use 1 part Demi Color to 1 1/2 parts Balancing Lotion. Whatever you are looking at was probably supposed to say "Rusk Balancing Lotion" but got cut off for whatever reason. Here is the link to the formulation chart PDF:

It also has information on processing times.
