After a hot summer, your hair may feel drier than usual. Before applying treatments, determine its porosity level with this straightforward test trusted by hair care experts.
Wash your hair with shampoo and rinse thoroughly to remove residues. Once dry, snip a small section (or use a strand from the ends if hair is long) and place it in a bowl of room-temperature water. Wait 2-4 minutes and observe:
1. Hair stays on top (low porosity).
2. Hair floats (medium porosity).
3. Hair sinks (high porosity).

Knowing your hair's porosity guides effective care. Here's tailored advice for each type, based on proven hair science.
Low porosity hair has tightly closed cuticles that resist moisture absorption, often leading to product buildup and a stiff, straw-like feel. Opt for lightweight, liquid products like clarifying shampoos and hair milks that absorb without greasiness.
Medium porosity hair balances moisture absorption and retention well, holding styles and color effectively. Limit frequent coloring or heat styling to prevent damage. Use protein-rich deep conditioners occasionally to sustain optimal hydration.
High porosity hair loses moisture rapidly due to damaged, raised cuticles, causing frizz and dryness. Seal in hydration with leave-in conditioners, oils, and butters to smooth cuticles and lock in moisture.
