Hair Styling Products: Coating Action and Adding Body

What product can slightly increase the diameter of the hair with a coating action, adding body to the hair?

Options:

A. Hair sprays

B. Shampoos and conditioners with silicone

Answer:

The product that can slightly increase the diameter of the hair by adding a coating, thereby adding body, includes hair sprays and certain shampoos and conditioners with silicone.

A product that slightly increases the diameter of the hair with a coating action, adding body to the hair, could be a hair spray or specific volumizing shampoos and conditioners that include silicone or other coating agents. Hair spray, in particular, is a common styling product that stiffens hair by providing a coating over the hair. It was first developed by Chase Products in 1948. The use of hair spray can hold styles in place for extended periods and may leave the hair feeling 'crunchy' if not brushed out.

On the other hand, many shampoos have a pearlescent appearance due to the addition of glycol distearate, a wax derived from stearic acid that can also contribute to the coating effect, thereby increasing the hair's diameter slightly and adding more body. Moreover, the inclusion of silicone in shampoos and conditioners can provide additional conditioning benefits while also creating a coating that makes each strand of hair thicker.
