     それは髪(かみ)の生(は)え方(かた)や寝(ね)癖(ぐせ)よるものであれば、スタイリングで補(ほ)正(せい)できるのですがそれができないくらい「ぺちゃんこ」の状(じょう)態(たい)なら注(ちゅう)意(い)が必(ひつ)要(よう)かもしれません。

     Sore wa kami no hae kata ya neguse yoru mono deareba, sutairingu de hosei dekiru no desu ga sore ga dekinai kurai “pechanko” no jōtai nara chūi ga hitsuyō kamoshiremasen.

     If it is due to the way the hair grows or simply bed head, it can be corrected with styling, but you must take care not to get to a nearly unsalvageable “pechanko” condition.
