I didn't watch the video, but I can understand - she's doing what seems best for her hair. I have a family member that tried to stretch between relaxers and her hair suffered as a result. So, she went back to her 8 to 12 week relaxer routine, and her hair is thriving (it's MBL and thick). To most, every 4 weeks may seem excessive, but I wouldn't presume to tell anyone what they should or should not do to their hair. If her hair does reject this method, I hope that she does a "look what I've learned" update video in an effort to help others.
