How to say "brow" in Japanese

• 額ひたいJLPT N3approx.Common
  nounThe neutral word for the forehead; it covers 'brow' in phrases like 'wipe one's brow' or 'a high brow'. It sits equally well in writing and in everyday speech.
  額ひたいの汗あせをふきなさい。↗

  Wipe the sweat from your brow.
• でこCommon
  nounA colloquial word for the forehead — 'brow' in the wipe-your-brow sense — normally written in kana; its casual flavor suits relaxed talk. Adding the polite prefix お gives おでこ.
• おでこCommon
  nounThe polite-prefixed form of でこ; it refers to the forehead, so it covers 'brow' in that sense. Typical contexts: commenting on a wide forehead or the bump left by a knock.
  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.

All three mean the forehead — 'brow' as in wiping sweat from it, none covering the eyebrow sense; 額 is the neutral word, while 「でこ」 and 「おでこ」 are kana forms, 「でこ」 colloquial and 「おでこ」 its polite-prefixed counterpart.
