Think of it like shingles on a roof - it's made up of overlapping scales that protect the inner layers of the hair shaft. Here's a little more about it:
* Structure: The cuticle is composed of keratinized cells that are flattened and tightly packed.
* Function: It acts as a barrier to protect the hair from damage, such as heat, chemicals, and friction. It also helps to keep the hair hydrated and prevent it from becoming brittle.
* Appearance: The condition of the cuticle can significantly impact the appearance of the hair. A healthy cuticle makes hair look smooth, shiny, and manageable. A damaged cuticle can lead to frizz, dullness, and split ends.
