How does hair cuticle shape moisture absorption?
Hair cuticle shape dictates water entry and exit, influencing a strand's hydration level and overall health.

What happens to textured hair when ceramide levels are low?
When ceramide levels are low, textured hair becomes porous, prone to dryness, frizz, and breakage due to a compromised cuticle barrier.

Does silk pillowcase material influence hair’s natural oils?
Silk pillowcases minimize friction and absorb less moisture, helping hair retain its natural oils and reducing breakage.

What is the science behind hair friction during sleep?
Hair friction during sleep stems from mechanical forces acting on the hair's cuticle, exacerbated by dry conditions and abrasive surfaces.

Can hair porosity change over time from care?
Hair porosity's behavior and appearance can be influenced by care, though its inherent structure remains a foundational characteristic.

What scientific principles explain fabric friction’s effect on hair cuticle integrity?
Fabric friction damages hair cuticles by lifting scales and causing breakage, a process influenced by fabric texture, hair's moisture, and chemical history.

How do different pillowcase materials impact hair hydration?
Pillowcase materials directly influence hair hydration by affecting friction and moisture absorbency, with smoother fabrics like silk supporting better moisture retention.
