Final answer:
For hair with excellent porosity, a mild perm solution is recommended, as it is gentler on the hair and reduces the risk of damage. Consult a professional for the best perm solution for your hair.
Step-by-step explanation:
For hair with excellent porosity, you should select a mild perm solution. Excellent porosity means that the hair shaft can easily absorb and hold onto moisture, which makes the hair more porous. Using a strong or aggressive perm solution on hair with excellent porosity can lead to over-processing and damage.
Mild perm solutions have a lower pH level and are gentler on the hair. They allow for a more controlled processing time, reducing the risk of damage. These solutions are ideal for hair that is already porous and in good condition.
It's important to consult with a professional cosmetologist or hairstylist to determine the best perm solution for your specific hair type and condition.
