For Nguyen and many other Vietnamese Americans, nail salons have long served as a gateway to American culture. They have been a stepping stone to a more prosperous life, offering flexible working hours, a sense of community and an easier way to make money.

Much like at restaurants and hair salons, the industry standard for tipping at the nail salon ranges around 15 to 20 percent, and it is generally recommended that if you've received extra services or specialty designs, a minimum of 20 percent is appreciated.

The prevalence of Korean nail salons in New York came partially from the fact that these salons offered cheaper options for manicures and pedicures, which opened up the industry to customers across the economic spectrum. Yet, the cheaper the prices posted by the salon, the less tip money the workers will receive.

If you have weak or brittle nails, consider a regular or shellac manicure as they are less damaging. If longevity is a priority, opt for a gel or dip powder manicure. If you want to add length or dramatically change your nail shape, acrylics could be your best bet.
