Can environmental factors like sun and pollution affect hair’s porosity?
Sun and pollution elevate hair porosity by damaging the cuticle and degrading proteins, causing strands to absorb and lose moisture rapidly.

Can nightly hair protection methods truly prevent damage to delicate strands?
Nightly hair protection methods can significantly prevent damage to delicate strands by reducing friction and preserving moisture.

How do ancient oils hydrate textured hair?
Ancient oils hydrate textured hair by smoothing cuticles, reinforcing lipid barriers, and for some, penetrating the cortex to reduce protein loss.

What ancestral factors contribute to the unique moisture needs of textured hair?
Textured hair's unique moisture needs stem from elliptical follicle shapes impeding oil distribution and a distinct lipid structure leading to higher permeability.

How do hair cuticles react to different sleep surfaces?
Hair cuticles react to different sleep surfaces primarily through friction, with smoother materials like silk reducing cuticle lifting and moisture loss, preserving strand health.
