Underarm odor is a common concern that can affect daily comfort and self-confidence. Many people ask: Does underarm hair removal stop underarm odor? The answer isn’t a simple yes or no—it depends on various factors. In this article, HBIO Clinic explores how hair removal may help reduce odor and what you should know before choosing a solution.

Does Underarm Hair Removal Help Eliminate Odor?

Underarm hair removal is often chosen for smoother, cleaner skin. But can it actually stop odor? While hair removal doesn’t directly cure body odor, it can help reduce it in certain cases.

Reasons why underarm hair removal can help reduce underarm odor:

  • Reduce bacteria: Underarm hair can create a humid environment and is a place for bacteria to accumulate, causing odor. When underarm hair is removed, bacteria will have less opportunity to grow and develop, thereby helping to reduce odor.
  • Easier hygiene: After hair removal, cleaning the underarm area becomes easier, helping to remove sweat and dead cells, minimizing the formation of odor.

However, underarm hair removal cannot completely cure underarm odor because:

  • Underarm odor is mainly caused by sweat glands: Underarm odor is caused by the secretion of sweat from the apocrine glands combined with bacteria on the skin, not just the existence of hair. If the odor problem originates from sweat glands, underarm hair removal will not completely solve the problem.
  • Still need intensive treatment: If you have severe underarm odor, you need to find other treatments such as using deodorants, medication, or consult medical solutions such as Botox injections or sweat gland surgery.

In short, does underarm hair removal eliminate odor? Underarm hair removal can help reduce odor in some cases by eliminating the environment for bacteria to grow. However, to completely cure underarm odor, you still need to have a combination of treatments and proper care. If underarm odor is a serious problem, consult a doctor to find the right treatment.

How long does underarm hair removal last? Hair removal methods

Laser Hair Removal

Laser is one of the most permanent hair removal methods. After each treatment, the hair is completely destroyed, and most of it will not grow back for about 6 months to 1 year. However, to maintain the results, you may need maintenance treatments after about 1 year.

Waxing or Shaving

Methods like waxing or shaving provide temporary results, usually lasting 2 to 4 weeks. After this time, the hair will grow back and the procedure will need to be repeated.

IPL Hair Removal

Like lasers, IPL also provides long-term results. However, you will need several treatments to achieve the best results. After completing a course of treatment, the results will last for 6 months to 1 year, but you may still need maintenance treatments.

How to care for underarm skin after underarm hair removal

How to care for underarm skin after underarm hair removal
After underarm hair removal, the skin under the armpits can be sensitive and easily irritated. To help the skin recover quickly and maintain smooth skin, you need to take some steps to properly care for the skin. Below are some notes and ways to care for the skin under the armpits after underarm hair removal:

Keep the armpits clean and dry

After hair removal, you need to keep the armpits clean to avoid bacteria that cause irritation or infection. You should wash the armpits with warm water and a gentle shower gel, avoiding products containing alcohol or strong chemicals.

Avoid using deodorant immediately after treatment

After hair removal, you should not use deodorant or products containing alcohol, because they can irritate and damage the skin under the armpits. Let the skin rest for at least 24 hours before using these products again.

Apply moisturizer or soothing gel

After hair removal, the skin may feel dry or irritated. Use a moisturizer or soothing gel that contains natural ingredients like Aloe Vera or chamomile extract to soothe and hydrate the skin. This helps the skin recover quickly and reduces itching.

Avoid direct sunlight

The armpit area after hair removal can be very sensitive, so avoid exposing the skin to direct sunlight for at least 48 hours. If you need to go out, you should wear long-sleeved shirts or use sunscreen for the armpit area to protect the skin from the harmful effects of UV rays.

Limit strenuous exercise and sweating

After hair removal, avoid sports or activities that cause a lot of sweating within 24 hours to minimize the risk of skin irritation. Sweat can clog pores and cause inflammation.

Avoid shaving or plucking immediately after hair removal

At this time, the pores are still open and the skin needs time to recover. Avoid using shaving, plucking or waxing methods after hair removal to avoid further damage to the skin.

Do not scratch or rub vigorously

The skin under the armpit area after hair removal may feel itchy or slightly uncomfortable. However, avoid scratching or rubbing vigorously as this can damage the skin, leading to inflammation or even infection.

Drink enough water and eat healthy

A healthy diet and adequate hydration help keep skin healthy from the inside out. Drink enough water and supplement foods rich in vitamins A, C, E to support the skin regeneration process.
