Why Do Some People Have 'Wet' Hair and Others Have 'Dry' Hair?

Hair feels wet or dry depending on what it’s made of. Imagine your hair is like a sponge, some sponges absorb lots of water and feel soft, while others don’t hold much water and stay stiff. Wet hair has more moisture inside the strands, making them feel softer and smoother. Dry hair doesn’t have as much moisture, so it feels rougher. Your hair gets its texture from the kind of protein it’s made of, like a special kind of glue called keratin.
