Porosity
The layer of the hair that has the biggest influence on the hairs porosity is the:
Cuticle layer
The hairs porosity is always increased after using a:
Alkaline pH product
When evaluating porosity, normal and resistant hair will feel:
Smooth and silky
The hairs elasticity is due to the nature of the:
Cortex layer
Neutralizer of fixers usually contain:
Hydrogen peroxide
Neutralizers must be applied right after:
Blotting
The waving process can only be halted completely by:
