アッシュ

• Reading: アッシュ
• Romaji: asshu
• Pronunciation: /aɕ.ɕɯ/

Meaning

Ash-toned hair colour; a cool grey-ish shade that neutralises warm tones in Asian hair.

アッシュ is one of the most popular hair colour categories in Japan. Because Asian hair tends to have warm red/orange undertones when lightened, achieving a cool ash tone requires specific techniques and is highly sought after. Salons offer many variations: アッシュグレー (ash grey), アッシュブラウン (ash brown), アッシュベージュ (ash beige), and more. Requesting アッシュ at a salon instantly communicates that you want cool-toned, non-brassy colour — making it one of the most commonly used hair colour terms.

Examples

1. アッシュっぽい色にしたいんですけどブリーチ必要ですか？ I want an ash-ish color — do I need bleach for that?
2. アッシュグレーにしたらめっちゃ透明感出た。 I went ash gray and it gave me amazing translucency.
3. アッシュって色落ちしたらオレンジっぽくなるのが悩み。 The annoying thing about ash is that it fades to an orangey tone.

Usage Guide

Context: hair salon, beauty, fashion

Tone: stylish, sophisticated

Do Say

• アッシュ系のカラーって透明感あって好き。 (I love ash-toned colours — they have such translucency.)
• アッシュにしたいけど色持ちはどう？ (I want to go ash — how long does the colour last?)

Don't Say

• 「アッシュにしてください」だけだとバリエーション多すぎて美容師が困る (Just saying 'make it ash' is too vague — there are many ash variations)

Common Mistakes

• Expecting アッシュ without bleaching on dark Asian hair — achieving true ash tones on naturally dark hair almost always requires some level of lightening

Origin & History

Regional notes: Used across Japan. One of the most commonly requested hair colour categories at Japanese salons. Especially popular because it counteracts the warm undertones of Asian hair.
