    Study Notes

    • Hair conditioning serves multiple purposes beyond just softening and preparing hair for styling: protecting against chemical and environmental damage
    • Hair conditioners, also called protective-conditioners, comprise various substances that provide protective, restorative, and shimmering properties
    • Cationic surfactants (e.g., quaternary ammonium phosphates) and polymers facilitate combing; proteins, protein derivatives, and hydrolysates restore and protect the hair structure; fats lubricate and give shine; glycols moisturize and lubricate; and silicones protect and reduce irritations
    • Conditioners work by reducing static electricity, restoring alterations, and smoothing the hair surface through electrostatic attraction, forming a protective film
    • Conditioning shampoos clean and condition simultaneously, saving time; rinse-off conditioners are used on very dry hair and require extended exposure time; leave-in conditioners do not rinse off and are suitable for normal and oily hair; foam spray conditioners are lightweight and versatile; hair oils can be used before or after washing to protect or condition the hair; and serums are recommended for dry hair.
