"a thick, heavy fringe"
What do you think is the most suitable way to ask for a "thick, heavy fringe" at the hairdresser's? (I think you say "bangs" in America).
I'm thinking "un flequillo poblado" might do the trick (although in Peru it's more common to hear "cerquillo" for "fringe", so we'd ask for "un cerquillo poblado").
Any other suggestions? Maybe incorporating "grueso"...? (Although that maybe implies the hair itself is "thick" in quality rather than the fringe.)

If you want a 'flequillo' like in that picture just go into any hairdressers in Spain and ask for the usual.
You already have the answer and, as you see, depending on where is the hairdresser from you will have to ´adjust´ your words.
un flequillo poblado would work fine in Argentina
However, to avoid a hairstyle catastrophe maybe you could have a picture at hand.
They will probably not cut it as you like, anyway ![]()
cerquillo fuerte (or con volumen if you want it really thick)
