Buy the Paul Mitchell Super Skinny Serum Anti-Frizz Blowout.

It does the one job a frizz serum has to do, and it does it for less money per bottle.

What was compared

  • Olaplex N°.9 Bond Protector™ Hair Serum · $32.00
  • Paul Mitchell Super Skinny Serum Anti-Frizz Blowout · $30.00

Five reasons

  1. 1. More serum, less money, every bottle

    Paul Mitchell runs $5.58 per fluid ounce against Olaplex's $10.67, and the bottle itself is bigger at 5.1 fl oz versus roughly 3 fl oz. You get nearly double the product for a lower per-ounce cost, not a trade-off, just a better deal.

  2. 2. Actually kills frizz, not just claims to

    Reviewers repeatedly call Super Skinny Serum the top salon smoothing serum, with blowouts staying frizz-free even in humidity. Olaplex No.9 users describe the opposite effect, hair left dry and frizzy, which is the exact problem a frizz serum is supposed to fix.

  3. 3. A proven best-seller beats a shaky newcomer

    Super Skinny Serum has years of steady 'cuts frizz fast' feedback behind it. Olaplex No.9 reviews are split, with buyers unsure it is even worth adding next to No.3 or No.7, which is not the confidence you want from a daily product.

  4. 4. Silicone-free sounds nice, results are the job

    Olaplex markets No.9 as silicone-free, which matters if you are actively avoiding silicones for scalp or buildup reasons. For most people just trying to beat flyaways, Paul Mitchell's lightweight silicone formula does the actual smoothing job more reliably, and if avoiding silicones is your rule then Olaplex is yours, but that is not most frizz-serum buyers.

  5. 5. Yes, Olaplex's name carries weight. Not here.

    Olaplex earned its reputation with patented bond-rebuilding treatments like No.3 and No.7, not with No.9, which is just a finishing serum. Paying extra for the Olaplex label on a plain smoothing product does not buy you that bond technology, so judge it as the serum it actually is.
