Quick science lesson: the curlier your hair, the harder it is for the natural sebum (the oil produced by your scalp) to travel down your hair. As a result, curls are notoriously dry and need a lot of moisture to thrive.
Of course, just how much your hair needs depends on the texture, density, and a slew of other factors. As someone with 4c hair, it is constantly parched. When I don't give it moisture, it tends to snap, crackle, and pop — and it looks dehydrated (as seen in the image above). So I've made sure to make moisturisers my BFF, so my curls look healthy and soft.
