I think what you may be talking about are torsion twists. These are an abrupt twist in the hair direction and are part of the hair structure. So other than manually altering them with style techniques (twist outs, heat, etc.), they are not permanently changeable. They do not indicate damage, they are just part of the hair. There are some blog posts that show torsion twists in more detail if you do a google. It's more common to occur in Afro-textured hair but even straight hair can have them, though usually in fewer numbers. Torsion twists are the "kink" in kinky hair. I have some sprinkled throughout my head, and they do disrupt the curl pattern in the strand, so that the curl loses its uniformity.
High Density, High Porosity, Medium Texture, 3B with some kink
