Under the microscope, hair strands look like shingles on a roof. Overlapping cuticle layers protect the fragile inner layers of every hair strand. Light reflects from this cuticle layer, giving hair its natural shine. When hair begins to look frizzy or dull it means the cuticle layer is damaged or no longer lying flat. On a molecular level, the bonds that hold the cuticle cells together weaken over time. The individual cuticles are raised as damage occurs and the hair strands tangle and break. The change in the way our hair looks and feels is often a reminder that a good hair conditioner is a necessity and should be used every time we wash our hair. Choose a conditioner that suits your hair type and ensure you apply to the mid-lengths and ends of the hair and not the roots or scalp. Shop by your hair type on the main menu if you’re not sure which conditioner is best for your hair.
