Can Billy be used on underarms?

Yes, absolutely! Billy works perfectly on underarms, whether you're a man or a woman. It's even one of the easiest areas to maintain with this trimmer .

Why Billy you'll love Billy for your armpits:

Underarms are a sensitive area with thin skin and folds—exactly the type of area billy was designed for. The cut-resistant ceramic blade allows you to pass over this area without any risk of cuts, even in the creases and folds.

Unlike a conventional razor that easily cuts you under the arms (especially if you go quickly), billy remains safe. You can raise your arm, stretch the skin a little, and pass billy calmly without stressing, it takes 2 minutes, no need for cream or rinsing.

Billy doesn't shave close to the skin like a bladed razor, and that's precisely what protects you from problems. You get an almost close shave (especially without a guard, there's a little less than a millimeter left) but without the cuts, the irritation, and especially without that regrowth that stings and itches for three days. With Billy, the regrowth is soft and comfortable because the hair isn't cut at an angle under the skin.

Armpit technique:

• Raise your arm to expose your armpit.
• Billy goes all over the place (armpit hair grows in multiple directions)
• The built-in LED helps you see every hair, even the small ones
• It takes 20-30 seconds per armpit max

You can use Billy without a clipper for a close-cropped result, or with the 3mm clipper if you prefer to keep it a little longer. Many people find that without a clipper it's perfect for underarms: neat, tidy, and comfortable.

The advantage of underarms is also hygiene. Well-groomed underarms mean less sweat clinging to hair, less odor, and your deodorant works better. In summer (and for athletes) it's truly a game changer.

Billy in the shower for armpits, it's ultra fast: you wash, you pass Billy for 30 seconds on each armpit, you rinse, it's done. It just becomes a reflex in your routine.

For women, Billy completely replaces razors or underarm wax. No more cuts, irritation, itchy regrowth, or the hassle of waxing. One quick pass and you'll be clean for several days.

On the men's side, more and more men are taking care of their underarms for hygiene and comfort. Billy allows you to do it discreetly and quickly, without looking like you spent three hours on it.
