Cuticle Cells and Hair Structure
The outermost layer of hair is called cuticle cells. These cells protect the inner parts of the hair shaft and prevent water from entering.
Different Layers of Hair
The cuticle is the outermost layer, the cortex provides strength, color, and texture, and the medulla may or may not exist in certain strands.
Animal-Derived vs. Plant-Based Keratin
Most hair products that contain keratin are made from animal parts, which is not vegan-friendly or sustainable. Choosing cruelty-free keratin products made with plant proteins is an alternative.
Cortex and Medulla
The cortex is the middle layer of hair that provides strength, color, and texture to each strand. The medulla, if present, contains soft spongy masses of cells and does not affect chemical treatments.
Conclusion
Understanding the different layers and components of hair is essential for caring for and maintaining healthy locks.
