What product can be used to equalize the porosity of the hair?

Fillers are specifically designed to equalize the porosity of the hair. When hair has uneven porosity, meaning that some areas absorb moisture and color differently than others, fillers help to create a more uniform texture. This is especially useful in hair coloring processes, as it allows for better absorption of color and a more even finish. Fillers work by filling in the gaps in the hair cuticle, providing a more consistent surface for the application of products.

Conditioners, while beneficial for overall hair health and moisture, do not specifically target porosity issues in the same way that fillers do. Gel and serum serve different purposes; gel is often used for styling and adding hold, while serum can be used to add shine and manage frizz, but they do not address the underlying problem of uneven porosity. Thus, fillers stand out as the most effective product for equalizing hair porosity.
