Those of us who can’t live without regular blowouts know we’re nuts for continuously turning a blind eye toward the damage that even the highest-end blow dryers can inflict on the hair. (For the record, we are not dim-witted, we are vain—and we’d rather look good now and suffer bad hair down the line.) My fellow blowout devotees: what could possibly be more gratifying than a hairstyling tool that gives solid results every time, without ever damaging your hair? That notion may sound like a contradiction, but when it comes to the Japanese hairstyling device called the Repronizer, it’s all true. I have discovered that, every time I use the Repronizer, the quality of my hair actually improves.
