Type 3 hair, characterized by loose curls, requires lightweight ingredients like aloe vera and jojoba oil to enhance curl definition and maintain moisture without weighing the hair down.

In contrast, Type 4 hair, known for its tight coils and kinks, needs richer, more nourishing ingredients like shea butter and castor oil to deeply moisturize and protect against dryness and breakage.

These differing ingredient choices cater to the unique structures of Type 3 and Type 4 hair, ensuring each hair type receives the specific care it needs for health and vitality.
