hair growth help!!

so to start, i really need help on growing my hair. my hair has always been long and healthy and shiny. junior year i balayaged it and got highlights twice and it was still healthy and shiny. a few months after the balayage, in june. the hair lady dyed it all blonde instead of balayage. but it was fine it worked out it didn’t cause no harm. all summer my hair was fine. then at the end of september if my senior year i decided to blend out my roots cause i didn’t wanna dye it again, so i got box dye, first mistake. i blended out some peices through my hair and it finished out looking greyish/green. so i got color oops, second mistake. a few weeks after color oops my hair started breaking off

and i had to get it cut a few times to even out. now i’m here and i’m in desperate need to grow my hair and feel confident again.

i just don’t know what products or anything to use so if any of you babes know some please help ❤️ here’s pics for an idea!!

first is balayage, second is all blonde, third is now (: my heads also tilted back more in the third pic so it looks longer then it is
