Theorem hair products are designed to be used in a variety of ways depending on the product. Generally, Theorem products should be used after shampooing and conditioning the hair. For styling products, such as mousses, gels, and creams, apply a small amount to damp hair and style as desired. For finishing products, such as hairsprays, apply a light mist to finished styles. For treatments, such as masks and oils, apply to damp or dry hair and leave on for the recommended amount of time before rinsing.
