Which of the following correctly defines hair's terminal classification?

The classification of hair as terminal refers to the thick, dark, and coarse hair that typically grows in specific areas of the body, such as the scalp, beard, underarms, and pubic region. Terminal hair is different from other types of hair, like vellus hair, which is finer and softer and found covering most of the body. The defining features of terminal hair include its increased pigmentation, length, and density compared to other hair types.

Understanding terminal hair is essential in cosmetology, as it affects various aspects of hair treatment, styling, and hair growth patterns. This classification is crucial for professionals when considering hair removal methods, designing hairstyles, or recommending hair care products that suit the specific type of hair.
