Unhealthy hair usually has a rough texture, lack of shininess and luster, have split ends, lack of moisture and elasticity even after treatment and easily broken. Damaged hair will also get tangled up and result in knots due to hair dryness.
Healthy hair should never feel brittle and dry, but smooth and hydrated. Typically, if you have long hair that means it's growing out healthily, but it is possible to have long, damaged hair if you color it too often. So pay attention to the feel of those locks!
