If you have straighter hair, invest in dry shampoo
Curly girls, we're all about moisture. Wavy girls can have problems with oiliness. Bangs mean that you'll be touching your face more than usual to touch them up, etc, which means they'll get oilier. A travel-size dry shampoo in your handbag will go a long way for when your bangs are starting to get that stringy, greasy look. Try Drybar's Detox Dry Shampoo, $13, which smells great, but doesn't make your hair feel like straw.
Bring your inspiration with you... and your glasses
If you saw Ciara on the red carpet with the bangs you want, or Sophie Turner, or even Nicole Scherzinger, bring those pictures with you. Find as many of them as you can find from as many angles so that your stylist can know what you want and know how to adapt it for you. Also, if you wear glasses, they're going to affect how long your bangs will be and how they're going to be styled — so be sure to take them along.
