Question: 1 / 400

What hair type typically has the least amount of tensile strength?

Coarse hair

Medium hair

Fine hair

Fine hair is characterized by its thin and delicate structure, which contributes to having the least amount of tensile strength compared to other hair types. Tensile strength refers to the ability of hair to withstand tension or pulling without breaking. Fine hair’s smaller diameter means that it has less overall mass and strength, making it more prone to damage from stretching or excessive manipulation.

Coarse hair, on the other hand, has a thicker diameter and a higher tensile strength due to its stronger structure. Medium hair falls in between coarse and fine hair and therefore has moderate tensile strength. Curly hair can vary widely in strength depending on the exact type of curls, but generally, it is not defined by having the least tensile strength. Thus, fine hair stands out as the hair type most susceptible to breakage under tension, reflecting its lower tensile strength.
