Bleaching Black Hair, Then Dyeing Blue

I had previously been dyeing my hair black, 3 or 4 times, and needed to get the black dye out. I had been using Garnier Nutriese Soft Black all over my head.

I used Satin Bleach and Enzyme developer, 40 volume first, then a 20 volume to get some of the orange out. I only wanted the front half of my head to be blue. So I pinned back the unwanted hair, used a mixing bowl and comb, did it one line of hair at a time. This was the first day, with the 40 volume. I stupidly did not take a picture of my hair after the 20 volume.

I put tape over my ears to protect them, wore gloves. I squeezed some Blue Velvet hair dye in the mixing bowl and went from there.
