  6. If you want the area to be hair-free, consider getting hair removed by laser which eliminates irritation from excessive shaving. If a series of laser appointments is out of your budget and you still want to get rid of the hair under your arms, you can reassess the way you shave. It’s important to moisturize the hair and skin with a conditioning shaving cream to reduce pulling and friction. You also want to avoid dull razor blades that require repeated swiping, and make sure to shave in the direction of the hair growth, which is most often upward, so that you aren’t tugging at the follicle.
