- A soft texture denotes healthy hair
- Healthy hair can move easily, because the texture is soft .
- As you may also know, healthy hair has adequate elasticity and tensile strength. This allows it to stretch and recover- without breaking.
- Healthy hair has natural sheen, or luster- as the outermost layer of the hair shaft reflects light. It has elasticity, it can stretch more than just a little. It does not get tangled when wet. The water content of healthy hair gives it a straight feel or appearance.
