Relaxers, texturizers, and texlaxing can by synonymous because they are synonymous. In the actual hair world (licensed cosmetologists--not kitchen 'ticians, authors, bloggers, posters and YT "gurus" who have never had a day a professional training) there is no such differentiation. A relaxer is meant to permanently relax the natural texture--not completely straighten. Mixing in buffers, time variations, and application can all vary but it doesn't change the fact that they're all a different (and unprofessional) names for a relaxer. It bothers me when people act like they're actually all different things. They're not.
