Why is low porosity hair so hard to maintain?

Low porosity hair can be harder to maintain because the cuticle layer of the hair shaft is tightly packed, which makes it difficult for moisture and products to penetrate the hair shaft. As a result, low porosity hair can be more prone to product buildup, which can leave hair feeling heavy, greasy, and weighed down. Additionally, because low porosity hair does not easily absorb moisture, it can take longer to dry, and heat styling tools may be required to open the cuticle and allow products to penetrate. This can make low porosity hair more susceptible to heat damage and breakage. To properly care for low porosity hair, it is important to use lightweight, water-based products that can penetrate the hair shaft and to avoid heavy oils and butters that can cause buildup. It is also important to use heat styling tools sparingly and to incorporate deep conditioning treatments to help hydrate and nourish the hair.
