There are a couple of possible causes for having dead ends. More often than not, it’s caused by an overload of chemical products and chemical treatments done to your hair. These treatments can include bleaching, rebonding, hair color, and so on.
Frequent use of traditional shampoo and other hair products that contain harmful chemicals can also contribute to damaging your hair. This is because these chemicals tend to dry out your hair to the point that it loses most of its moisture. This is the point where your hair starts to become drier and rougher.
Hair damage can only get worse from there, especially if you don’t pay close attention to letting your hair recover or in doing the necessary steps to bring back lost moisture.
