When working with very porous hair, what should a stylist avoid?

When working with very porous hair, applying strong perm solutions should be avoided because such solutions can cause excessive damage to the hair structure. Very porous hair is already compromised and has gaps in the cuticle layer, which makes it prone to breakage and over-processing. Strong perm solutions contain higher concentrations of active ingredients that can further weaken the hair, leading to unwanted dryness, brittleness, and even more severe damage.

In contrast, mild perm solutions are better suited for porous hair as they are less likely to strip away moisture and cause irreparable harm. Conditioners can be beneficial, as they help to strengthen the hair and reduce damage during the perming process. Additionally, using heat styling tools must be approached with caution, but it's not the primary concern compared to the chemical action of strong perm solutions on porous hair. Thus, avoiding strong perm solutions is crucial in protecting the integrity of very porous hair during the perming process.
