Nerissa Irving did a YouTube video talking about how she washes her hair. It is a two part video. I can't link the first video, because there is a shower scene... lol. But above are a few screen shots of of the first and second video. Before Nerissa washes her hair, she does a color check/correction. She looks for any spots where there may be sun damage or embedded lint. She then uses Bigen to color correct those spots. I can link part two of the video where she shows how she moisturizes her hair and creates her big curls -
Thanks Nerissa! I also did a blog a while back on an alternative color spot correction here.
