Type 4 hair is often described as coily or kinky—it's naturally dry and spongy in texture, and can range from soft and fine to thick and coarse. Type 4 hair features tightly coiled curls with a distinct "S" pattern. The curls are small in diameter and have a springy, bouncy texture. These strands form tight zig-zag curls right from the scalp and are prone to significant shrinkage, which can make detangling challenging.
Because coily hair struggles to retain moisture, it can be more susceptible to breakage. Regular use of conditioner is key to keeping the hair hydrated and tangle-free. Coily hair benefits from reparative ingredients, such as nourishing oils and butters, to strengthen and moisturise the strands.
