地肌

1. Origins, structure, and basic meaning

• Structure: 地肌 (じはだ) is a compound noun for the bare scalp visible beneath the hair.
• Basic usage: 地肌が見える makes the exposed scalp the perceived subject after hair is parted, while 地肌に風が触れる marks the place touched by air after a hat is removed.

2. Common pitfalls and similar expressions

• Scalp rather than skin in general
  • Both 髪を分けた地肌 and 帽子を脱いだ地肌 refer to scalp skin. These inputs do not support broadening the word to bare skin over the whole body.
