When you sweat a lot and feel irritation in your armpits. The problem becomes even bigger when you start feeling body odor and see your clothes staining from this excessive sweating. To combat this, the first thing that comes to mind is shaving the underarms.

But, does shaving armpits stop sweating for real? There is no proof that your armpit hairs are responsible for excess sweat production but there is a connection between sweat collection and bacterial growth in your armpit hair. Let’s discuss this in detail and get you an answer to “Does shaving armpits reduce sweat?”

    Part 1: Why Do Armpit Hair Sweat? 

    Why Do Armpit Hair Sweat?The two main glands responsible for sweat production are the apocrine and eccrine glands. When the body temperature is high, these glands produce sweat. The sweat comes out of the tiny pores in our body and cools down the body temperature by evaporation. You must have heard of “evaporation causes cooling”. Sweat also lets out the waste materials from our bodies. 

    What’s the role of armpit hair in this? Armpits are the areas where sweat glands are most commonly found. This means there will be lots of sweating in the armpits and the armpit hair contributes to this sweat management. 

    Hair As A Wick

    One theory says that the armpit hair acts as a wick in drawing away the sweat from your skin, allowing proper ventilation, and evaporation. This leads to the regulation of body temperature and a cooling sensation. 

    These hair also reduces the friction between your armpits and the torso so that you can move without any sensation of discomfort. 

    Hair As A Barrier

    Opposite to the first theory, there is another belief. According to this, your armpit hair traps the sweat and causes a moist environment. This environment acts as a perfect breeding ground for the bacteria. As bacterial growth increases, there will be more odor and risk of infections. 

    Part 2: Will Shaving Armpits Reduce Sweat?

    Will Shaving Armpits Reduce Sweat?The armpit hair causes the accumulation of sweat and body odor, so what is the solution? Does shaving underarms reduce sweat? Shaving them can help you stay fresh and smell good. Let’s see how it helps. 

    Role of Shaving Armpits in Sweat Production

    Armpit hairs themselves cannot affect the production of sweat but they do play a role in causing discomfort in your pits. Therefore, shaving can be your solution to drive away that uncomfortable feeling. Moreover, as the hair responsible for sweat collection and bacterial growth will be gone, there will be less body odor and risk of infection.

    Clean armpits also allow better ventilation and let the antiperspirants absorb well. As a result, you will feel fresh throughout your day. 

    Are you wondering if thick hair that grows after shaving might worsen the problem?  Shaving does not have any effect on the thickness of your hair. To know more, read Does shaving make hair thicker and grow faster? 

    Factors Causing Individual Variations 

    Shaving can be helpful in most cases however you can expect variations from individual to individual. This is because sweat production is influenced by some factors and these factors indirectly determine the usefulness of shaving your armpit hair. 

    • Genetics: There are people who naturally sweat more than others even in a cold environment. In such cases, shaving the armpit hair will not give you any significant benefits against increased armpit sweating. People with these genetics will have to use antiperspirants more often and keep a check on their hygiene more carefully 
    • Hormonal influences: Hormonal changes can also affect the sweat production. For instance, increased levels of adrenaline cause the apocrine glands to produce more sweat. You also sweat more during menopause. Those suffering from hyperthyroidism face excessive sweating as well
    • Stress and anxiety: During stressful situations, your stress hormones become active. These hormones, adrenaline, and cortisol, activate the fight or flight mode of your body. As the mode becomes active, the body temperature increases and you start sweating more than usual
    • Body temperature: Changes in your body temperature also affect sweat production. Reduced temperature minimizes sweating to retain heat within your body while high temperature causes excessive sweating 
    • Exercise or physical activity: Exercise or extreme physical activities increase the rate of your metabolism which results in more heat production. Consequently, there will be excessive sweating, moisture in your armpits, and high bacterial growth 

    Part 3: How to Get Rid of Sweating in Shaved Armpits? 

    How to Get Rid of Sweating in Shaved Armpits? Shaving armpits does not reduce sweat production but doing so will allow you to look groomed and reduce the underarm odor associated with your pit sweating. So, is there any way that can help you fight the sweating? Yes, there are! Let’s discuss. 


    Deodorant can help with reducing body odor but if you are looking for a product to reduce sweat, try using antiperspirants. Over-the-counter antiperspirants have aluminum salts as their active ingredients. These salts absorb the moisture, turn into a gel, and block your sweat glands from producing sweat. 

    These antiperspirants work for most individuals. If they do not work for you, you can use stronger antiperspirants with 13% of aluminum salts in them. You can use them after bathing or at night when your body is cool. 

    Absorbent Products

    You can also try using absorbent products like sweat-absorbing cotton pads. These pads are mostly reusable and can absorb all the moisture from your underarms. 

    They can be a temporary solution to excessive sweating and cannot be used for sensitive skin. So, you can also wear sweat-resistant fabrics like cotton, linen, merino wool, and bamboo. These fabrics are lightweight and highly absorbent. They allow proper ventilation and reduce the unnecessary moisture collected in your armpits. 

    Maintain Hygiene 

    Maintaining your hygiene does not have a direct effect on reducing sweat but it is necessary to keep body odor away from you. 

    The steps you can take to maintain your hygiene include regular showers, wearing clean clothes, and washing your armpits properly during the shower. After you are done showering, dry your armpits and then wear clothes. Other than this, remove your underarm hair regularly, and take a shower after your exercise or strenuous physical activity. 

    Lifestyle Changes 

    Lifestyle modifications can also help you sweat less. For instance, eating spicy foods causes more sweat production so you can avoid such foods. Moreover, caffeine and alcohol also increase the body temperature and cause excessive sweating. 

    Instead of these, you can drink more water throughout the day and replace caffeine with healthy fresh juices. Furthermore, eat foods that can be easily digested. These foods contain those rich in fiber, Vitamin B, and magnesium like beans, lentils, spinach, and other leafy green vegetables.

    Your armpits are like a close-pitted area where sweat will accumulate and the armpit hair facilitates this accumulation. Shaving can help in improving the ventilation of air, evaporation of moisture, and prevention of bacterial growth. In this way, you can fight sweat production to a great extent just by shaving. 

    However, there are genetic, hormonal, stress-related, and exercise-related factors that can cause variations from individual to individual. So, you can combine shaving with some other sweat-reducing techniques according to your body’s conditions. 

    Moreover, if excessive sweating still persists, you can seek help from a professional.
