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.

“Our major universities are now stuck with an army of pedestrian, toadying careerists, Fifties types who wave around Sixties banners to conceal their record of ruthless, beaverlike tunneling to the top.”
—Camille Paglia (b. 1947)
“If there is nothing new on the earth, still the traveler always has a resource in the skies. They are constantly turning a new page to view. The wind sets the types on this blue ground, and the inquiring may always read a new truth there.”
—Henry David Thoreau (1817–1862)
“... there are two types of happiness and I have chosen that of the murderers. For I am happy. There was a time when I thought I had reached the limit of distress. Beyond that limit, there is a sterile and magnificent happiness.”
