# 爪のラップ（nail wrap）

### マニキュアが「爪をラップする」しくみ

ネイルエナメル（マニキュア）は爪表面に薄い膜を形成し、爪内部の**水分蒸発と外部からの水分侵入を同時に防ぎます。**これにより、割れを抑え、しなやかで美しい爪をキープしやすくなります。

📍 色付きの[ネイルカラー](https://tpandco.jp/collections/nailcolor-all-brands)だけでなく、[ベースコートやトップコート](https://tpandco.jp/collections/base_top_coat_all)も同様の保護効果があります。

詳しくは、ブログ記事の[「マニキュアは、爪に悪いのか？ マニキュアのケア効果」](https://tpandco.jp/blogs/items/nail_polish_is_good)をご参照ください。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://helpcenter.tpandco.jp/docs/definition-of-words/neirukeanisuruto/norappunail-wrap.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
