Texture
People often use texture for the width of each strand: fine, medium, or coarse. Some also use it for how straight or curly hair is.
Density
Density is how many strands grow on your scalp. Low density hair shows more scalp.
Porosity
Porosity is a term stylists use for how easily hair takes in and holds water.
How they affect volume
Fine hair can go flat under heavy products, whatever its density. Light products and lifting the roots as you dry can help.
Hair type charts
You may see hair types described by numbers and letters, from fine and straight to thick and tightly coiled. They are a starting point, not a rule.
FAQ
See a doctor or dermatologist about scalp conditions, hair loss, or sudden thinning.
General information, not medical advice. Patch test new hair products, keep them out of your eyes, and stop use if irritation occurs. See a doctor or dermatologist about scalp conditions or hair loss.
