Porosity refers to the hair's ability to absorb and retain moisture.
How do we test the porosity of the hair? Fill a glass with water at room temperature and put one / two strands of hair in the water. If the hair remains on the surface then the porosity is low. If it goes to the bottom then the porosity is high and if it sinks only to the middle of the glass then the porosity is medium.
Hair characteristics with low porosity:
- It takes a long time for the hair to become saturated.
- It takes a long time for the hair to dry.
- The products tend to clog the hair.
- Natural oils do not penetrate the thread very well.
- The hair is considered quite healthy and shiny.
- It is not prone to break or split ends.
- Hair can look healthy but does not have much volume and elasticity.
- Light products such as gel or foam are more suitable than creams or hair butter.
- It takes heat to open the cuticles so that products or moisture can penetrate.
- Apply the products on wet hair, when the cuticles are open for optimal results.
- Use light oils such as argan or jojoba.
Hair characteristics with medium porosity:
- The hair is usually very elastic and has a lot of volume.
- It is very easy to maintain.
- Absorbs and retains moisture easily.
High porosity hair characteristics:
