How do chemical treatments alter hair porosity and dye retention?
Chemical treatments increase hair porosity by lifting cuticle scales and damaging internal structure, leading to quicker dye uptake but also faster color fading.

What is the pH range for common chemical hair treatments?
Chemical hair treatments typically range from highly acidic (pH 2.5) for some neutralizers to extremely alkaline (pH 14) for strong relaxers, all altering hair's natural pH of 4.5-5.5.

How do chemical treatments alter textured hair porosity?
Chemical treatments significantly raise textured hair porosity by lifting cuticles and altering internal protein bonds, leading to increased moisture absorption and loss.

How do chemical treatments affect hair cuticle structure?
Chemical treatments lift and compromise the hair cuticle, leading to increased porosity, dryness, and reduced strength.
