Final answer:
The product that should be used to equalize the porosity of a client's hair is a conditioner.
Step-by-step explanation:
The product that should be used to equalize the porosity of a client's hair is a conditioner. Conditioners are specifically designed to help restore and balance the moisture and pH levels of the hair, which can help equalize porosity.
Conditioners contain ingredients such as emollients and humectants, which help to fill in the gaps in the hair cuticle and smooth out the hair shaft. This can help to reduce porosity and make the hair more manageable.
For best results, it is recommended to use a conditioner that is specifically formulated for your hair type and porosity level. This will ensure that you are providing the right level of hydration and nourishment for your hair.
