Want to go back blonde!

Sooo about 3 weeks ago I dyed my hair “magenta brown” and it turned out more purple. Since then it has faded so much and my blonde roots are growing back in, and my hair looks uneven light brown, red, and purple. It’s terrible! I just want to go back blonde so I don’t have to keep up with my hair so often. (I dyed my hair because of a mini life crisis but ANYWAYS lmao) I just need some tips how to go about the process. And please don’t say go to a salon because I am a new/young mother and I really unfortunately can not afford a salon visit any time soon. I’m thinking something from Sally’s? Please help!! Thank you guys! 💓
