Here's why:
* Structure: The cuticle is the outermost layer of the hair shaft, composed of overlapping scales that resemble shingles on a roof.
* Function: It acts as a protective barrier, shielding the inner layers (cortex and medulla) from damage and environmental factors like heat, chemicals, and friction.
* Appearance: The condition of the cuticle greatly influences the shine and smoothness of hair. A healthy cuticle reflects light well, giving hair a glossy appearance. Damaged cuticles can lead to frizz, dullness, and tangles.
