I have 3c 4a hair types and my 4a is at the roots of my head. How can i keep my 4a from breaking off
You can keep both textures from breaking off by cowashing, deep conditioning once a week or every 2 weeks, monthly protein treatments (if you're not protein sensitive), and doing protective or low-manipulation styles such as twists, braids, finger coils, and flat twists. Just be sure not to braid or twist your hair too tight or you might encounter breakage and thinning around the edges and roots.
its not going to break, just moisturize it
