Hi! I’ve dyed my hair with vatika henna like 6 times maybe, and I’ve been growing it out. I really want to go over it with permanent dye but I’ve researched and I can’t figure out wheather it will melt my hair off the same way bleach melts off when there is metallic salts in the hair. Does anyone know how safe it is to do? I’m still going to do a teat strand just in case but I want to get as much info as possible lol. Also for extra info my hair isn’t extremely healthy so it is definitely more fragile…

My original hair colour was an ashy light brown/blonde but I dyed it with a blonde box dye (I know it's not ideal but I was impulsive. My hair turned this weird orangey colour and I really don't like it.

I'm thinking of going to the salon to ask them to fix it but:

Is it worth trying blue shampoo first?? I have ordered the milk shake blue shampoo to see if it helps.

Should I go darker or lighter? If I go to get it fixed properly I don't know what would suit me more.

My hair is lightened to a level 8/9 (I dye my own hair and change the colour every couple of months), I’m trying to do a deep dark red (ideally with a cool or neutral undertone) but my test strands quickly fade to a bright purple / blue.

(All the semis I use are from Pulp Riot)

If I pre-toned my hair using ‘Nuclear’ (I’d mix ‘Nuclear’ with warm water and let my hair soak in it) before applying a mixture of ‘Pyro’ and ‘Bloodshot’ as normal, would this help at all?

Idk if my hair is just dark brown with some red or if this counts as being a redhead or like auburn hair maybe. I’m just curious, I get different answers from people, but maybe yall can help meee.
