Dull, lifeless hair
Why does hair sometimes look dull and lifeless?
Some of these factors can cause hair to lose some of its ability to store moisture. As a result, the hair becomes prone to breakage and looks brittle. The stress we put on our hair can damage the outer cuticle layer. When this happens, the hair no longer reflects light and looks dull and lifeless. Another undesirable side effect of this damage is that it makes the hair difficult to comb and style.
