Pubic hair and head hair differ significantly in their structure and appearance, even though both are types of body hair. The primary differences lie in their shape, texture, and the thickness of their outer layer.
According to one reference, pubic hair appeared flatter, curlier and had a thicker cuticle, giving it a coarser appearance compared to scalp hair.
Key Differences
While both types of hair serve protective functions, their physical characteristics vary, influencing how they look and feel.
Structure
The shape of the hair follicle determines the hair's cross-sectional shape and curliness.
- Head Hair: Often more cylindrical in cross-section, leading to straighter or wavier strands depending on the individual.
- Pubic Hair: Tends to be flatter in cross-section, which contributes to its characteristic curliness.
Appearance and Texture
The visible differences in texture and appearance are a result of their structural variations.
- Head Hair: Generally appears finer and can range in texture from very straight to wavy to curly.
- Pubic Hair: Is typically coarser and curlier, with a flatter shape that creates more bends and twists in the strand.
Cuticle Thickness
The cuticle is the outermost protective layer of the hair shaft, made up of overlapping cells.
- Head Hair: Has a cuticle layer, but it may be relatively thinner compared to pubic hair.
- Pubic Hair: Features a thicker cuticle layer. This thicker layer contributes to the hair's coarser feel and appearance.
Quick Comparison Table
Here's a simplified overview of the main distinctions based on the provided reference:
Characteristic | Head Hair | Pubic Hair |
---|---|---|
Shape | Often more cylindrical | Flatter |
Curliness | Varies (straight to curly) | Tend to be curlier |
Cuticle | Thinner | Thicker |
Texture | Finer | Coarser appearance |
These structural differences are adapted to the specific locations on the body and their respective functions.
