Julianne Moore and Margot Robbie Use the Treatment 85-Year-Olds Say Makes Hair “Fuller”

If you had asked me about Olaplex two months ago I would have said there’s no way a brand can live up to the amount of hype it’s received. But now that I’ve actually tried it, I will admit that I am too cynical — it deserves the praise. The real testament to its efficacy is that it’s used by people of all ages, shoppers and celebrities alike. For the latter, take the recent example of Julianne Moore and Margot Robbie, 63 years old and 33 years old, respectively, both of whom used Olaplex’s No. 6 Bond Smoother hair treatment as part of their Golden Globes glam this weekend. 

The actresses arrived on the red carpet for their respective Golden Globe nominations, Moore for May December and Robbie for Barbie. Moore sported a sleek updo and Robbie had flowing blonde tresses. No. 6 Bond Smoother is a leave-in, long-lasting, reparative styling treatment so versatile it was used on both actresses’ juxtaposing hairstyles. 

Celebrity stylist Halley Brisker, per a press release, said he used No. 6 on Julianne Moore to “max out the shine… and seal the cuticle.” For Margot Robbie, her stylist Jacob Schwartz said he used No. 6 to “add the moisture back in” to her highlighted hair to keep it looking “lit from within.” He added that it “protects against breakage and keeps the hair strong.”

The crux of No. 6 Bond Smoother (and all Olaplex products) is its proprietary and patented bond-building technology. The explanation of why and how it works is science-heavy, but the gist is this: Per the brand, the ingredient penetrates hair at a deeper layer than most products. There, it heals damaged strands (regardless of whether it's the root, mid, or end) to prevent and reduce breakage, shedding, and frizz. You can Olaplex’s Bond Smoother on air- or blow-dried hair and you should see smooth, frizz-free, silky, and defined strands for up to 72 hours. 

One of the 39,000-plus five-star Amazon shoppers said they began using Olaplex’s Bond Smoother because their hair was “looking old and damaged.” After using this their hair is “softer, silkier, smoother, healthier and younger looking.” An 85-year-old shopper said this made their hair “appear fuller and healthier.”
