How to say "forehead" in Japanese

• 額ひたいJLPT N3approx.Common
  nounThe neutral word for the forehead, the part of the face above the eyebrows; it also covers the 'brow' sense and fits neutral description where a colloquial tone would be out of place.
  額ひたいの汗あせをふきなさい。↗

  Wipe the sweat from your brow.
• でこCommon
  nounThe colloquial form, usually written in kana; it refers to the same forehead but sounds casual and can come across as blunt, so it belongs in relaxed conversation rather than neutral description.
• おでこCommon
  nounでこ with the polite prefix お; in conversation this is the natural way to mention the forehead, softer than bare でこ and comfortable in most everyday talk.
  前髪まえがみが、おでこにかからないように髪かみを上あげることをおすすめします。↗

  I recommend putting up your hair so your fringe doesn't get on your forehead.

Use 額 for the forehead in neutral description or writing; in casual speech pick 「おでこ」, 「でこ」 with its polite prefix, or bare 「でこ」 when a blunt colloquial tone fits.
