Overly porous hair occurs when the hair has an excessive ability to absorb moisture due to a compromised cuticle layer. This condition often arises from various factors such as chemical treatments, excessive heat styling, or environmental exposure. As a result, the hair loses its ability to retain moisture and essential oils, leading to a dry, damaged state.

When hair is overly porous, it becomes fragile and brittle, making it more susceptible to breakage. The cuticle, which is the hair's protective outer layer, becomes rough and damaged, further contributing to the hair’s inability to maintain its strength and elasticity. This culminates in a texture that is not only dry and damaged but also lacks the shine and softness that healthy hair typically has. Consequently, maintaining a proper hair care routine with moisturizing treatments and protective styling is essential for individuals with overly porous hair to restore its condition and prevent further damage.
