I am a natural dirty blonde and I recently dyed my hair a medium reddish brown. I wanted to go lighter so I can go closer to my natural but every time I tried to go lighter, it wouldn't look any different. So I bleached it to try and have a light foundation but all it did was make it look orange and I added an ash blonde to to try and counter it but it still looked orange. My roots are dark so I wanted to go to a light brown so I could let my hair just grow out but it turned a nasty, dirty brown-green. I put a darker brown to try and make the green go away and it just looked worse. Not to mention I missed a huge spot on the back of my head that is still blonde. I put liquid detergent in my hair to wash out the color. Is there any way to try and fix this myself or should I just go to a salon and have them strip it and put the right color in it? Any help is much appreciated. Thank you in advance!

Stop trying to fix it it will fall out
