Most armpit hair usually only grows to be two to three inches long, so an inch and a half should do the trick. Whatever length you choose, there is one iron-clad rule to follow: Whatever hair is visible when you put your arms down at your sides, you trim them down until they disappear. Whether you trim or shave is ultimately up to you too, of course.
Select your comb length, and then use the aforementioned trimmer and cut that hair down to size. The discussion of armpit hair came up: how much is too much? All your body hair has this quality, even that on your head and beard. It's armpit hair. It hides under there and helps wick sweat away from the skin—and sends out pheromones to attract mates.
The photographer friend asked me to raise my arms up, then to set them at my sides. I was wearing a tank top, and when I followed his order, a tuft of armpit hair stuck out from my arm, popping forward like a little weed. That paper, Axillary Odor: Experimental Study of the Role of Bacteria, Apocrine Sweat, and Deodorants , concluded that one of the best ways to prevent underarm stink is to get rid of underarm hair.
Francis had to back up a bit to help me understand why. There are two kinds of sweat glands, apocrine and eccrine.
Eccrine sweat glands are all over your body lovely , while the apocrine type are concentrated in hairy spots, like your nether regions and those pits I am constantly shaving. Normal bacteria hanging out on your skin combine with apocrine sweat to produce an odor—the one you know as B. Francis says. Why on earth would anyone need help smelling? The theory goes that our stank pits actually help us find potential mates.
Just as pups greet each other with a rear-end sniff at the dog park, you might be turned on or off by the scent emanating from the pair of pits parked on the bar stool next to yours. Sensitivities to androgen levels also influence where terminal hair grows on the body, for everyone. When more androgens are produced, more areas will grow terminal hair, such as the legs, arms, chest, stomach, and feet.
This is because the armpits release an odor containing pheromones, a naturally-producing chemical that plays a role in sexual attraction. This makes the pheromones even stronger. Researchers came to this conclusion by asking the men in the study to wear a shirt for 24 hours and to abstain from using any deodorant or scented body products.
This included a stressful mock job interview and saliva samples to measure cortisol. Armpit hair prevents skin-to-skin contact when doing certain activities, such as running and walking. Tired of sweating excessively or dealing with sweat stains on your clothes? Shaving your armpits can help since hair actually holds onto moisture. Some people naturally sweat more than normal, though.
This is called hyperhidrosis , a condition that causes people to sweat excessively from their hands, feet, and armpits. A study involving men found that removing armpit hair by shaving significantly reduced axillary odor for the following 24 hours.
