I've never really been a fan of using black to create silver. I find it results in a very dull and flat silver, almost matt looking.
Why don't you try 10/86 or 9/81 in KP?
Any silver colour will fade though and if you use 6% any virgin brown hair will lift and expose warmth.
Number 1 rule of hair colour - tint will not lift tint.
Your options are bleach, or lift and deposit like magma, which as you're toning afterwards would just a waste of product.
You also can try 10/0 which breaks that number 1 rule due to the ammonia content. Although I feel this is unreliable...
MFI says no, just koleston. But I've done it, however you won't be covered by insurance should anything go wrong.
I'd recommend using shades as mix tones. For example of you need blue mix tone then use 7/81 or 5/81 depending on requirements.
1) I use wella. The product depends on my starting point but I'm likely to use illumina or colour touch.
2) There are reasond why you'd do a root stretch:
- To add dimension to a full head of foils
- To transition someone from foils or full head tint/bleach to a balayage
- To help fix ghost...
She sounds pathetic if I'm being honest. Shes acting as if its some horrific tragedy and her hair has fallen out or gone orange... I mean come on you've got a bit of tint staining on your skin!
Try not to let her bother you as anyone who agrees with her is just as ridiculous!
Don't be hard...
I totally agree.
I don't think it really stands as a criticism of a brand when you're not weighing colour and using matching developer, you'll only ever get the best performance with them, I understand they're more expensive but the benefits outweigh the higher cost for me.
