What causes variations in hair’s water absorption?
Hair's water absorption varies due to cuticle integrity, internal structure, environmental humidity, and chemical treatment history.

How does hair porosity influence product effectiveness?
Hair porosity, influenced by cuticle structure and external factors, dictates how effectively products hydrate, strengthen, or weigh down textured hair.

What causes hair cuticle damage?
Hair cuticle damage occurs when its protective scales lift or erode due to mechanical friction, chemical treatments, thermal styling, or environmental stressors.
