Trigger word is "retro_hair" but words like "bangs", "big hair" and "messy hair" work as well. Weighting these words can result in flatter or puffier hair depending on your preference. Leaving out or not adding weight to "big hair" and "messy hair" but adding "bangs" will produce a more mid-90s look with flatter hair whereas emphasizing "big hair" and "messy hair" will produce a more 80s-early 90s look.
