Okay, I am going to start by letting you all know, shrinkage is a normal and good thing. Although it hides our hair's true length, shrinkage is one of the best indicators of textured hair health. Natural hair that is properly hydrated and moisturised will shrink. Shrinkage is also a sign of your hair's elasticity and its resistance to breakage. Shrinkage is an indicator that your hair is healthy, hydrated and happy but even though your hair is happy, it can really frustrate the owner. For those who may have a much looser wavy curl pattern or just aren't familiar with the concept of shrinkage, let me explain. Shrinkage is a decrease in length when hair goes from wet to dry.
