Here is a video of when I dyed half of my hair teal and the other half purple. I bleached my hair twice before doing this. This is on my old YouTube channel and my new channel is Forever The Sickest Flower Child. I used Beyond The Zone hair dye, usually around ten dollars per bottle. This is my all time favorite dye. If you have any questions just ask me!
Step 1: Separate Your Hair Unevenly Down the Middle
I did mine unevenly because I wanted some of the colors to come together instead of being completely separated.
Step 2: Dye Half of Your Head One Color
Step 3: Now the Other Side
Step 4: Let the Dye Sit for 30-45 Minutes
Step 5: Wash It Out
Once again, heres the video.
