4C hair features the tightest curls of all, with coils that can be fine, wiry, or coarse, but often do not clump without styling product assistance. It’s more prone to shrinkage and dryness compared to other types, including 4B, and requires the most intensive moisture and protective styling products. Key products for 4C hair include heavy butters, thick creams, and penetrating oils that provide deep moisture and protection, unlike the defining gels and lighter lotions used for other types. Leave-in conditioners, twist and loc butters, and heavy sealants are essential to maintain health and manageability, aiming to protect the hair rather than enhance curl definition which is a primary focus in less tightly coiled types.
