Olaplex, long celebrated for its hair-repair technology, has earned widespread praise from both shoppers and celebrities. The brand’s No. 6 Bond Smoother, a leave-in reparative styling treatment, has been spotlighted on red carpets by stars such as Julianne Moore, 65, and Margot Robbie, 35.
During a 2024 appearance, Moore showcased a sleek updo, while Robbie’s hair flowed in soft blonde waves. Celebrity stylists used the Bond Smoother to enhance their hair’s health and appearance.
Halley Brisker applied it to Moore to “max out the shine… and seal the cuticle,” while Jacob Schwartz used it on Robbie to “add moisture back in” and protect highlighted strands against breakage.
The key to Olaplex’s success is its patented bond-building technology. The formula penetrates hair deeper than standard treatments, repairing strands from root to tip, reducing breakage, shedding, and frizz. The product works on both air- and blow-dried hair, leaving it smooth, silky, and frizz-free for up to 72 hours.
Shoppers have echoed these results. One reviewer on Amazon noted that the Bond Smoother transformed hair that was “looking old and damaged” into strands that are “softer, silkier, smoother, healthier, and younger looking.” An 85-year-old user reported hair that appeared “fuller and healthier.”
Olaplex No. 6 Bond Smoother continues to rank among the most popular hair products for consumers seeking lasting shine, repair, and protection.
