What is a common indication of high porosity in hair?

A common indication of high porosity in hair is rapid moisture absorption and loss. Hair with high porosity possesses gaps and holes in the cuticle layer, which allows moisture to enter easily but also leads to quick loss of that moisture. This characteristic can make the hair feel dry and brittle, as it is unable to retain hydration effectively.

Hair that absorbs moisture quickly may also experience issues such as frizz and lack of elasticity, as the moisture can cause the hair shaft to swell and then dry out rapidly. Understanding porosity is essential for choosing the right products and care techniques, as individuals with high porosity hair often benefit from heavier, more moisturizing products to help seal in hydration. This knowledge helps in managing the overall health and appearance of the hair, particularly in styling and maintaining its integrity.
