What determines the strength of the chemical permanent wave lotion?

Hair density
Condition of the hair
Length of the hair
Hair color

The correct answer is: Condition of the hair

The strength of the chemical permanent wave lotion is primarily determined by the condition of the hair. The condition refers to the hair's overall health, including factors such as porosity, elasticity, and any previous chemical treatments it may have undergone. Hair that is damaged or overly porous may react differently to the perm solution than healthy hair, requiring careful consideration when determining the strength of the lotion to be used. When assessing the hair, a stylist must ensure that the lotion used is appropriate for the specific state of the hair to achieve the desired wave without causing unnecessary damage. Proper evaluation of hair condition helps in selecting the right formula to ensure optimal results while minimizing risks of over-processing or unwanted outcomes.
