Which type of hair is characterized by having tightly coiled curls?

The type of hair characterized by having tightly coiled curls is coily hair. Coily hair typically has a tighter, more spiral-like curl pattern compared to other hair types. This hair texture can range from soft, looser coils to very tight, defined corkscrew curls.

Understanding hair types is crucial in cosmetology, as each type requires specific techniques and products for effective styling, maintenance, and care. Coily hair often tends to be drier than straight or wavy hair due to its structure, which can make it more challenging for natural oils from the scalp to travel down the hair shaft. This understanding plays a significant role in how cosmetologists approach treatments and styles for clients with different hair textures.
