hair dye and help pls

I NEED SUPER COOL HAIR DYE RECCOMENDATIONS!!!

but it also has to be easy to hide cz super religious Christian parents 

I'm trying to convince them to let me get like brown highlights or something 

and then Id like add colors when I go back to uni or wtv

I was thinking of getting like oil spill kinda highlights? like blue pink purple and teal but I also wanna see if there are any other options that I might like more?

also I cut my bangs too short which normally I wouldn't have really cared cz short bangs don't really look that awful on me but like this time I ended up cutting it both short AND thick so I look like a fucked up dora

Give like hairstyle recommendations to make my bangs look less fucked or js like hairstyles that hide the bangs of whatever

cz everything I find online is either too much to wear to class or js makes me look chopped asf

so yea if there's anything I can do to make my hair not look like dora send help my way pls
