Hey! I've got no clue what I'm doing so I am just going to start from the beginning and hope I don't bore you.
I went from not dying my hair for three years so all my hair was my natural colour a dirty blonde/ lightest brown . Picture one
I then decided to go pastel pink. I used a box dye l'oreal and it lighten my hair to a yellow/blonde. Picture two
I then used touch of silver twice weekly purple shampoo left on for 1hour.
The next day my sister used a toner called p10 (don't know the brand name) and my hair turned out this colour picture three .
A week after bleaching my hair I used carnation pink dye by directions and conditioner and it didn't take to my hair . I thought I could have been I didn't using a clarifying shampoo before hand and also didn't use silicone free conditioner .
So today I tried to go pastel purple . I used neon blue , flamingo pink , and carnation pink with a silicone free shampoo.
And it's super patchy my root took but the rest it's patchy and some place didn't take at all ,
I think my bace wasn't good enough that's why it's went so patchy so I need to bleach again so my questions are :
How can I removed what purple is in my ( without using colour b4 can't stand the smell ) ?
How do I safely bleach my fine hair again without causing to my damage?
Would going to sallys getting bleach and developer be better than using box dyes?
Would a 3%10vol developer work on my hair ? Current colour and roots ?
Pastels are tricky, and often require a second application to get them even. I would give your hair a good shampoo, no conditioner and blow dry. Then mix your mix slightly darker than before and re-apply. Make sure you leave it on for several hours.
If you want to lighten further wait at least a month after your last bleach/box dye, and bleach over coconut oil. You should be able to get a nice lilac on that base though
If you want to lighten further, wait at least a month and then you can do a bleach bath. Your base looks quite good but it might be that its a ti y bit too dark and its grabbing the purple as a toner instead of lilac.
You can try re applying and leaving it on for longer or diluting a darker purple with conditioner so its a tiny bit darker than the lilac.
