Why Should Men Shave Their Armpits?
Shaving or trimming armpit hair is a personal choice, but many men find it improves hygiene, comfort, and overall freshness. Here are the most common benefits:
- Odor reduction: Less hair means fewer places for odor causing bacteria to cling, helping reduce underarm smell.
- Better deodorant contact: With less hair blocking the surface, deodorant and antiperspirant can reach the skin more evenly and work more effectively.
- Comfort during workouts: Shaving or trimming can reduce friction, tugging, and sweat buildup—especially under fitted gym gear.
- Aesthetic appeal: Some men prefer the cleaner look of shaved or neatly trimmed underarms, especially for a more groomed appearance.
Many men also report that deodorant works better on shaved underarms, helping with odor control on active days.
Why Do Some Men Avoid Shaving Their Armpits?
Some men choose not to shave their armpits for a variety of personal, cultural, or skin related reasons. Here are the most common ones: (If irritation is a concern, learn how to prevent razor burn.)
- Grooming preferences: Some simply prefer the natural look, while others feel smoother skin stays fresher—it’s personal as sensitive skin may prefer trimming.
- Skin sensitivity: Underarm skin is delicate. If shaving leads to irritation, redness, or razor burn, many men avoid it—especially if technique or tools aren’t ideal.
- Sweat & comfort concerns: Hair can help wick sweat from the skin, while others feel smoother skin stays fresher. It often comes down to personal comfort and trial and error.
- Aesthetic choice: Some men like the fuller, natural appearance of underarm hair or prefer maintaining a neat, trimmed length rather than going completely bare.
What Tools You’ll Need for a Smooth Underarm Shave

How to Shave Armpit Hair: Step-by-Step Guide to Shaving Your Underarms
To shave your underarms smoothly, trim long hair first, soften the area in the shower, apply shave gel, then shave gently using light strokes in multiple directions as needed. Finish with moisturizer and avoid deodorant right away to reduce irritation.
Step 1
Select a Fixed Comb Length
The right comb length on your trimmer can help you tame full, natural growth that hasn’t been touched by a razor for a while – or ever. The King C. Gillette All-in-One Styler with 3 interchangeable combs for different lengths for you to choose from.
Why it matters: Trimming bulk first prevents razor clogging and makes shaving easier.
Step 2
Trim
Trim your underarm hair. Trimming the hair before shaving can help prevent clogged blades.
Why it matters: Shorter hair allows the razor to glide cleanly and reduces pulling or tugging.
Step 3
Shower
The water will help soften your underarm hair (which can be wiry) and make it easier for the razor to glide over your skin. King C. Gillette All-in-One Styler is waterproof so you can trim in the shower.
Why it matters: Softened hair requires less force to cut, helping reduce irritation.
Step 4
Lather Up with Shave Gel
A good lather helps to hydrate hairs, enhance razor glide, and protect your skin while you shave your underarms.
Why it matters: Shave gel improves glide, reduces friction, and helps prevent razor burn.
Step 5
Check for Dull Blades
Blade feeling dull or lubrication strips looking faded? It may be time for you to swap your blade refills before you begin.
Why it matters: Sharp blades cut cleanly and reduce the chances of redness and bumps.
Step 6
Shave with Light, Gentle Strokes
Attach a blade to your King C. Gillette All-in-One Styler. Shave with light, gentle strokes, rinsing often, and with the skin pulled taut.
Why it matters: Light strokes protect sensitive underarm skin and lower irritation risk.
Step 7
Rinse Your Blades Often
Run the blades gently under the faucet every few strokes, both the back and front sides of the blades, and then gently shake excess water off. Do not tap your razor against the sink or wipe against a towel; these habits can reduce the life of the razor by affecting the intricate design of the blade components. Rinsing the blades under running water helps to remove built-up shaving gel, hair, and dead skin.
Why it matters: Clean blades maintain better glide and last longer without damaging components.
Step 8
Shave in Multiple Directions
Because underarm hair grows in multiple directions, start downward, then sideways, and finish upward if needed re-lather between passes.
Why it matters: Shaving with the grain alone won't catch all hairs, multi-direction passes give smoother results.
Step 9
Reapply Shave Gel as Needed
You may find that you need to shave over the same spot in different directions to get a smooth shave. In order to help prevent shaving rash on your underarm skin, ensure that you reapply GilletteLabs Rapid Foaming Shave Gel before you re-stroke.
Why it matters: Never dry-stroke—added lubrication helps prevent razor burn and bumps.
Step 10
Rinse, Dry, and Moisturize
Moisturizing after shaving your underarms is critical – it helps soothe the skin.
Why it matters: Moisturizing calms freshly shaved skin and helps prevent redness or dryness.
Pro Tip:
“Avoid applying deodorant immediately after shaving. Wait at least 24 hours to prevent irritation and allow skin to recover."
Common Mistakes to Avoid While Shaving Underarms
Most underarm shaving irritation comes from avoidable mistakes like dry shaving, pressing too hard, or using dull blades. Avoiding these habits helps prevent razor burn, razor bumps, and post‑shave itching.
- Dry shaving: Always hydrate the hair and skin to prevent pulling and razor burn.
- Pressing too hard or using long, aggressive strokes: Gentle, short strokes protect sensitive underarm skin.
- Using dull or damaged blades: Replace blades when they tug or the lubrastrip fades for a cleaner shave.
- Using face razors on underarms: Face razors aren’t designed for thicker, multidirectional underarm hair. A body specific option like the GilletteLabs Body + Intimate Razor For Men with Magnetic Shower Hanger that provides safer control and smoother results.
