Clients with long hair can have what type of porosity?

• A. Even porosity
• B. Normal porosity
• C. Uneven porosity
• D. Low porosity

Answer: (C)

Porosity is how easily hair takes in and holds moisture or chemicals. In long hair, the ends have endured more wear, friction, sun exposure, and possible chemical processing than the roots. That extra exposure damage can raise the cuticle more at the ends, so moisture moves in and out at different rates along the length. That variability along the strand is what we call uneven porosity. So, long hair often shows uneven porosity because the ends behave differently from the scalp area. If porosity were uniform, you’d expect the same absorption pattern throughout the entire strand, which isn’t typically the case with very long hair.
