So I did a strand test with two of my dreads. I mixed the bleach and developer and applied it to two dreads. I then covered it in aluminum foil. I waited 30 minutes and then had a peek. They were still black some with a couple of brown. The other dreadlock had this reverse ombre effect where only the top portion had bleached. I removed the foil and waited another 30 minutes. After removing the product I noticed that the locks had not really bleached. Anyone know what I did wrong? The blue flash bottle said not to add heat so I did not, but was I supposed to? I dyed my hair black a year ago with Bigen so could that have played a part? By the way I used 30 volume developer.
By the way I know most members don't approve of bleaching hair. So please don't tell me to sit in the sun with a bottle of lemon juice or just don't respond if it is not going to be useful advice. I have enclosed a webcam snapshot. Thanks in advance!
