Does long side bangs work with someone who has a small forehead?

Anybody can look good in bangs, your stylist can cut them to be the most flattering length for you. Bangs can be very thick or they can be wispy, and may depend on the thickness of your hair, and especially thin bangs might make your forehead look smaller or larger. Ask your stylist what type of bangs your hair type can pull off, and decide from there if those are the bangs you want to get.
