What is the critical relative humidity for hair swelling?
Hair swelling noticeably accelerates beyond 60-70% relative humidity as water plasticizes keratin, particularly impacting textured or compromised strands.

How does hair absorb moisture?
Hair absorbs moisture through its cuticle and cortex, primarily via hydrogen bonds with keratin proteins, with porosity and lipid content shaping its hydration.

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 are the signs of low porosity hair?
Low porosity hair resists water absorption, feels smooth, takes extended time to wet and dry, and experiences product buildup on its surface.

Can damaged hair from chemical treatments regain its optimal moisture absorption capabilities?
Chemically damaged hair can improve its moisture absorption capabilities through diligent care, although its inherent structure may not fully revert to its virgin state.
