What type of hair is considered the thickest and strongest?

Terminal hair is recognized as the thickest and strongest type of hair on the human body. This category of hair is characterized by its coarse texture, greater pigmentation, and length compared to other types of hair. Terminal hair typically develops in areas such as the scalp, face, armpits, and pubic region, especially during puberty due to hormonal influences.

The structure of terminal hair includes a more developed medulla, which contributes to its strength and resilience. It also has a thicker shaft and a more substantial cuticle layer compared to fine or vellus hair. Fine hair is often softer and less pigmented, making it much less robust, while vellus hair is the fine, light hair that covers much of the human body and is even thinner and weaker than fine hair. Soft hair generally refers to any non-terminal hair that may not possess the same characteristics of strength and durability found in terminal hair.

The distinction between these types of hair is essential in hair removal practices, as each requires different techniques and considerations based on their structural differences.
