The Real Reason You're Struggling on Your Natural Hair Journey In order to have a successful natural hair journey, you must first understand exactly what the term natural hair really means. There are several different definitions of the term, but below I've provided the most common definition for natural hair, and the one that we will talk about most often . "The term natural hair is defined as relaxer-free hair, which is different from chemical-free hair. Chemicals, on the surface, are often considered dangerous, but this is often times not the case at all. Most chemicals that you encounter on a daily basis are perfectly safe and harmless. For example, water or H2O is a safe chemical."
