Coily (Type 4) Hair: The Definitive Guide
Coily, or Type 4, hair is characterized by tightly packed, S- or Z-shaped strands that require specific care to maintain hydration and prevent breakage.
Identifying Coily (Type 4) Hair
Coily hair, also known as Type 4, is distinguished by its tightly packed, S-shaped, or Z-shaped curl patterns that are evident from the scalp. Unlike wavier or curlier hair types, coily hair often appears shorter than its actual length due to shrinkage, sometimes as much as 75%. Strands can range from fine to coarse, but the defining characteristic is the very tight curl or zig-zag pattern. This hair type exhibits little to no defined curl pattern without product, and when stretched, individual strands often retain their tight coils.
