Protecting UV-exposed hair ceramide with oat oil

The hair shaft is composed of a cuticle, cortex and medulla. The cuticle is the outermost protective layer (consisting of overlapping scale-like cells) that provides the hair sensory and shine characteristics.


Ceramides are lipids that naturally occur in the hair strands. The hallmark of a healthy hair strand is a tightly packed cuticle layer which maintains its strength, elasticity, and shine, without it, hair becomes vulnerable to unwanted damage. The main purpose of ceramides is to 'glue' cuticle layers together to ensure the hair will lay flat and remain intact. Although ceramides occur naturally in the hair, sun exposure (UV light), over time, depletes them leading to raised cuticles, resulting in the loss of moisture, causing the hair strands to become fragile. Oat Cosmetics have developed Oat Lipid e (INCI name: Avena sativa (oat) Kernel Oil), a superior oat oil with a unique lipid profile and tested its efficacy to protect the ceramide content in hair after UV exposure, which effectively improves hair shine as well. 

The cuticles overlap like roof shingles, protecting the hair from chemical and physical treatments.1 The cortex is the major component of hair and is responsible for its mechanical strength and pigmentation.1
