Glossary Hair Shine

light-reflective quality indicating healthy, smooth hair cuticles

Hair Shine, also known as Hair Luster or Hair Sheen, refers to the light-reflective quality of hair, which gives it a glossy and healthy appearance. This shine is influenced by the smoothness of the hair cuticle, the natural oils produced by the scalp, and the overall health and hydration of the hair. Factors such as diet, hair care practices, and environmental exposure can impact hair shine.
