Understanding hair science is essential for stylists aiming to provide exceptional services and advice to their clients. Knowledge of hair care principles informs product choice, technique execution, and treatment suggestions, ultimately enhancing a stylist’s expertise and client satisfaction.
The Structure of Hair
Hair is primarily made of a protein called keratin, which gives it strength and structure. Each hair strand includes three main parts: the cuticle, cortex, and medulla. The cuticle is the outer layer that protects the inner components. The cortex is responsible for the hair's strength and color, while the medulla is the innermost part that is often absent in fine hair types.
Recognizing these components helps stylists make informed decisions. For example, if a client experiences frizz and split ends, recommending a deep-conditioning treatment can help seal and protect the cuticle, thus restoring shine and manageability.
