The 100 points

What stands out 100 pts

We split Fine Hair Shampoo into 6 standout parts. Each bar shows what the build earns.

  • ACleansing system23 of 39 pts

    The cleansing system sets how the shampoo lathers and how hard it washes. Sodium C14-16 Olefin Sulfonate, Cocamidopropyl Betaine, Sodium Methyl Cocoyl Taurate do this job here.

  • BHumectants14 of 14 pts

    Humectants (Panthenol, Glycerin) pull in water and keep the hair feeling soft.

  • CScalp actives0 of 13 pts

    Scalp-care ingredients (Biotin) are the reason to pick this over a plain wash.

  • DConditioning polymers12 of 12 pts

    Cationic conditioning polymers cling to wet hair and cut tangles. Cetrimonium Chloride, Hydroxypropyl Guar Hydroxypropyltrimonium Chloride, Polyquaternium-7 play that role here.

  • EOils and butters0 of 12 pts

    Oils and butters (Salvia Hispanica Seed Oil) soften the hair and seal in moisture.

  • FProtein and amino acids0 of 10 pts

    Hydrolyzed proteins and amino acids (Hydrolyzed Keratin) are added to coat and temporarily fill rough spots on the hair surface.
