Hair Conditioner - Types

Types

  • Pack conditioners, are heavy and thick, with a high content of surfactants able to bind to the hair structure and "glue" the hair surface scales together. These are usually applied to the hair for a longer time. The surfactants are based on long straight aliphatic chains similar to saturated fatty acids. Their molecules have a tendency to crystallize easily, giving the conditioner higher viscosity, and they tend to form thicker layers on the hair surface.
  • Leave-in conditioners are thinner and have different surfactants which add only a little material to the hair. They are based on unsaturated chains, which are bent not straight. This shape makes them less prone to crystallizing, making a lighter, less viscous mixture and providing significantly thinner layer on the hair. The difference between leave-in and pack conditioners is similar to the difference between fats and oils.
  • Ordinary conditioners, combining some aspects of both pack and leave-in ones. These are generally applied directly after use of a shampoo, and manufacturers usually produce a conditioner counterpart for this purpose.
  • Hold conditioners, based on cationic polyelectrolyte polymers, holding the hair in a desired shape. These have both function and composition similar to diluted hair gels.

Famous quotes containing the word types:

    “Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.”
    —Talcott Parsons (1902–1979)

    “He types his laboured column—weary drudge!
    Senile fudge and solemn:
    Spare, editor, to condemn
    These dry leaves of his autumn.”
    —Robertson Davies (b. 1913)

    “He’s one of those know-it-all types that, if you flatter the wig off him, he chatter like a goony bird at mating time.”
    —Michael Blankfort. Lewis Milestone. Johnson (Reginald Gardner)
