Which hair type is typically the thickest and longest lasting?

Terminal hair is characterized by being the thickest and longest-lasting type of hair. This type of hair is often found in areas of the body such as the scalp, beard, and underarms. Terminal hair undergoes a longer growth cycle compared to the other types, which allows it to achieve greater length and thickness.

Vellus hair, commonly referred to as "peach fuzz," is fine and short, whereas lanugo hair, often found on fetuses, is usually very fine and fine in texture. Intermediate hair, as the name suggests, falls between vellus and terminal hair in terms of thickness and length but does not reach the same density or longevity as terminal hair.

Due to the structural properties of terminal hair, it has a different composition and growth pattern, making it the most robust and lasting type of hair when compared to the others mentioned.
