Kind Code: A1 An object of the present invention is to provide a method for preventing entanglement of hair or fiber which is apt to be entangled, whereby the entanglement can be suppressed spontaneously and even if the entanglement occurs, the entanglement can be spontaneously released without performing an operation such as passing through a hand. I do. A method for preventing tangling of hair or fiber, comprising the step of contacting hair or fiber with a treating agent containing or blending the following components (A) and (B). (A) Aminopolyether-modified silicone containing a polyoxyalkylene structure that satisfies the following formula (I) 0.005% by mass or more and 5% by mass or less 0.01 ≦ Si / AO ≦ 1.6 (I) [In formula (I), Si represents the number of moles of silicon atoms in component (A), and AO represents the average number of moles of oxyalkylene added in component (A). ] (B) Aqueous medium [selection diagram] None【課題】絡まりが生じやすい毛髪又は繊維において、絡まりの発生を抑制し、絡まりが生じた場合にも手を通すなどの操作を行うことなく自発的に絡まりを解くことができる絡まり防止方法を提供する。【解決手段】毛髪又は繊維を、次の成分（Ａ）及び成分（Ｂ）を含有又は配合してなる処理剤に接触させる工程を有する、毛髪又は繊維の絡まり防止方法。（Ａ）下記式（Ｉ）を満たす、ポリオキシアルキレン構造を含有するアミノポリエーテル変性シリコーン ０．００５質量％以上５質量％以下 ０．０１≦Ｓｉ／ＡＯ≦１．６ （Ｉ） 〔式（Ｉ）中、Ｓｉは成分（Ａ）中のケイ素原子のモル数、ＡＯは成分（Ａ）中のオキシアルキレン平均付加モル数を示す。〕（Ｂ）水性媒体【選択図】なし
