Though it sometimes means daily maintenance, shaving is the easiest way to remove underarm hair. The key is to get as close a shave as possible by using a shaving gel and raising your arms so the skin is taut (giving you more access to the hair). Because underarm hair grows in so many directions, it's best to shave up, down and side to side. Take your time while shaving, it is not the time to rush.
Although safety razors provide a close shave (outperforming electric shavers by far), the results are temporary: regrowth usually occurs within two to three days.
For the smoothest, closest shave, always use a new blade and a light touch, applying as little pressure as possible. Wet the skin thoroughly and apply a shaving gel or cream (soap is too drying) to keep the skin soft and moist. Lather underarm hair with conditioner if shaving gel is not available. Shave right before you towel dry, when the hair is softer and more manageable.
If you need to shave a specific area twice, apply additional gel or cream. Rinse the skin and gently towel dry. Use oil or moisturizer to finish.
