When to use volume 10 versus volume 20 developer (dye, color, blonde)

[Bubblybunnie]

I bleached my hair, and now intend to apply wella 6A / 7A That's a medium/dark blonde. I intended to use 20 but the hair is so light after bleaching I wonder if using volume 10 may be more appropriate. My hair is currently doing fine but I do not want to damage it any more than I need but I also do not want it to look off since I will not be doing anything to it other than upkeep many months.

Will 20 be appropriate? Or 10? The Wella 6A/7A is a permanent dye.

The link below is an image of what it actually is now, my face is cropped out so do not be alarmed.

Thank you!!!

I would use 10 volume since you are depositing color and not wanting any lift.

Wella 6a or 7a will probably be much darker than you anticipate. 6a is likely to give you a medium brown and 7a is even more brown that blonde. Wella permanent runs 2-3 shades darker than it says. Read the reviews - everyone that uses wella says this.

Even 8a will get you a dark blonde/light brown that's more brown than blonde. To be honest, Wella 9a or a mix of 8a/9a might be more what you are looking for or maybe just 8a. Try a small strand for test before you commit.

I have very lightblonde hair now, everyone tells me I look much older, the truth hurts lol. I want to go darker. Like honey blonde
Almost white on top as for awhile i thought id go natural, rest is just faded lighter. Can't find wella brand.
Can you please suggest another brand. I understand the 20 vm thats in box color s too strong. My hair is in ( surprisinly)
Good condition.
Thank you.
