In a pre-perm analysis, which hair characteristic is assessed along with porosity, elasticity, and texture?

In a pre-perm analysis, assessing density is essential as it refers to the number of strands of hair per square inch on the scalp. Density influences how well the hair will hold a perm, as hair with a higher density may require more product and careful application to ensure even penetration of the perm solution throughout.

Understanding density helps stylists predict how the hair will react to the chemical process, ensuring the results are consistent and satisfactory. Evaluating this alongside other characteristics like porosity, elasticity, and texture creates a comprehensive picture of how the hair will respond to the perming treatment, enabling better decision-making in terms of timing and technique for optimal results.
