Hair is more intricate than it seems. While trendy hair products grab attention, understanding hair structure helps make better care choices. Each strand has three main layers: the cuticle, the cortex, and the medulla. Let’s break them down.
1. The Cuticle: Your Hair’s Protective Shield
The outermost layer, the cuticle, consists of overlapping cells resembling fish scales. It protects hair from UV rays, pollution, and chemicals. A healthy cuticle reflects light, giving hair shine and smoothness. When damaged, it leads to dullness, frizz, and breakage.
How to Maintain It:
Minimize heat styling.
Use a wide-toothed comb to prevent damage.
Apply serums or conditioners with silicone to seal and smooth the cuticle.
2. The Cortex: The Core Strength of Your Hair
The thickest layer, the cortex, makes up most of the hair’s weight and volume. It contains keratin, which gives hair strength, elasticity, and resilience. It’s also where melanin determines hair color.
How to Protect It:
Limit chemical treatments and excessive heat.
Use protein-rich treatments to strengthen and repair.
Apply deep conditioning therapies for hydration and resilience.
3. The Medulla: The Essential Yet Elusive Layer
The innermost layer, the medulla, is sometimes absent in fine or light-colored hair. It consists of loosely packed cells and soft keratin, potentially affecting hair texture and flexibility.
Since the medulla’s function isn’t fully understood, focusing on the cuticle and cortex has a greater impact on hair health.
Conclusion: Building a Strong Foundation
Understanding your hair’s cuticle, cortex, and medulla helps in making better hair care decisions. Protecting the cuticle, nourishing the cortex, and acknowledging the medulla can boost shine, strength, and resilience.
Remember, healthy hair isn’t just about products—it’s about knowledge. When you understand your hair’s needs, you can make empowered choices for its long-term health and beauty.
