Removing Red dye

Photo below is after bleaching out Manic panic. Obviously still stained pink.

This is Splat red that I had, I tried to bleach this and it hardly lightened, only a bit lighter at the tips.

This is my current hair. Slightly lightened Red Splat with Lavender Splat over top.

I'm gonna get Color B4 and try to go dark gray using diluted Arctic Fox Transylvania. I'm probably gonna order everything next week. I'll update with how it turns out.

The plan is to do a deep conditioner the day before I use Color B4 and deep condition right after. I will wait a couple days after the second condition to put the dye in, so that it will stick better.

A colour remover may get the red out, but clarify like crazy beforehand, and don't use any conditioners or products that will block it.
I would go for bleach powder/shampoo/oils before a colour remover on that depth of red though. generally colour removers work best on faded direct dyes.
If you can fade it to a light pink like the first pic, you can tone that to grey with a blue toned green dye diluted. I am not sure what base transylvania has, more blue than green i think?

The red won't fade except at the ends. I will do a clarifying shampoo. I did a bleach about a month ago and only the ends were pink, the rest stayed the same color, which is why I'm going to do the color remover.

Also yeah, Transylvania is a dark gray almost black with blue tones.

The bleach powder/shampoo/oils method is the best way of removing stubborn direct dyes.
Bleach can actually push the colour further in making it harder to remove.
Colour removers don't always work on direct dyes either.
So do the bleach powder/shampoo/oils treatment first, then use your colour remover if it doesn't get all the red out.

Start by soaking your hair in coconut oil for at least two hours, then mix 1oz bleach powder with 4oz shampoo and a teaspoon each of coconut and olive oil. Really work this mix into the oiled hair. Cover, and heat with a hairdryer, after 5-10 minutes rinse with hot water. Condition as usual and finish with a vinegar rinse.

I'll try that this weekend, I found a gray dye at Sallys that I will probably get if it works.

thank you
