The 100 points
We split Olaplex N°.0.5 Scalp Longevity Serum Treatment into 3 standout parts. Each bar shows what the build earns.
Scalp-care ingredients (Ceramide Eop, Ceramide Np, Ceramide Ap) are the reason to pick this over a plain wash.
Oils and butters (Oryza Sativa Bran Oil, Leptospermum Scoparium Branch/Leaf Oil, Coco-Caprylate/Caprate) soften the hair and seal in moisture.
Humectants (Glycerin, Propanediol, Sodium Hyaluronate Crosspolymer) pull in water and keep the hair feeling soft.
Optional
78 / 100. We have not found a shelf product that closes more of the gap yet.
