1.
one's natural hair; real hair
A person's own natural hair, as opposed to dyed hair, a wig, or extensions. Refers to both the natural color and texture of one's hair.
これは地毛の色です。
This is my natural hair color.
染めていないので、地毛のままです。
I haven't dyed it, so it's my natural hair.
学校の校則で髪を染めるのは禁止されているが、地毛が茶色い生徒もいる。
Hair dyeing is banned by school rules, but some students have naturally brown hair.
USAGE:
地毛 is commonly used in conversations about hairstyling and school dress codes. In Japan, some schools require students with naturally light-colored hair to submit a "地毛証明書" (natural hair certificate) to prove their hair is not dyed.
COMMON COLLOCATIONS:
- 地毛の色 (natural hair color)
- 地毛のまま (with one's natural hair)
- 地毛証明書 (natural hair certificate)
NUANCE:
The 地 in 地毛 means "natural" or "base," as in one's original, unaltered state. This is the same 地 found in words like 地声 (natural voice) and 地肌 (bare skin).
