Achieving Silky Smooth Underarms: How Many Laser Sessions Do You Need?

How Many Laser Sessions Do You Need?

When it comes to getting silky, hair-free armpits, many people turn to laser hair removal as a long-lasting solution. The popularity of this procedure is due to its effectiveness in reducing hair growth, saving time and effort in daily waxing routines. However, a common question that arises is, “How many laser sessions does it take to achieve optimal results?” In this blog post, we’ll explore the factors that influence the number of laser sessions needed for armpit hair removal and give you some ideas to help you understand what to expect.

Understanding the hair growth cycle:

To understand the concept of laser hair removal, it is essential to understand the hair growth cycle. Hair follicles go through three distinct phases: anagen (active growth), catagen (transition), and telogen (resting). The laser focuses on the hair follicles in the anagen phase because they contain more melanin, which makes the treatment more effective at this stage.

Factors that influence the number of laser sessions:

Several factors can influence the number of laser sessions required for armpit hair removal. Let’s take a closer look at these factors:

  • Hair color and thickness:

Laser hair removal is most effective for people with dark hair and fair skin because the laser focuses on the pigment in the hair follicles. Light or gray hair may not respond as well to treatment. Also, thick hair generally requires more sessions than thinner hair.

  • Hormonal factors:

Hormonal imbalances or conditions such as polycystic ovary syndrome (PCOS) can affect hair growth patterns. In such cases, multiple laser sessions may be required to achieve the desired results due to the presence of extra hair follicles stimulated by hormonal fluctuations.

  • Complexion:

There are different types of lasers available for different skin tones. Laser hair removal technology has evolved considerably, making it possible to treat a wide range of skin tones. However, darker skin types may require more sessions and specialized laser equipment to provide safe and effective treatment.

  • Treatment and maintenance program:

Laser hair removal usually requires multiple sessions to target hair follicles at different stages of growth. Depending on the area to be treated, most professionals recommend a series of 6 to 8 sessions spaced 4 to 6 weeks apart to ensure optimal results. Consistency in following the recommended treatment schedule is crucial for lasting hair reduction.

  • Single answer:

Each person’s response to laser hair removal will vary. While some people experience significant hair reduction after a few sessions, others may require additional treatments to achieve the desired result. The effectiveness of laser hair removal can be influenced by several genetic and physiological factors unique to each person.


Laser hair removal offers a comfortable and effective solution to achieve smooth armpits. The number of laser sessions needed for optimal results depends on several factors, including hair color, thickness, skin tone, hormonal factors, and individual response. Consulting a qualified professional is essential to determine the best approach and treatment plan for your specific needs. Remember to be patient and consistent throughout the process, as multiple sessions are usually required to achieve lasting hair reduction. Say goodbye to the hassle of shaving or waxing and enjoy the freedom of silky armpits with laser hair removal.


Q: Is underarm laser hair removal painful?

A: Laser hair removal can cause some discomfort, but is generally well tolerated. Most people describe the feeling as a rubber band snapping against the skin. The level of discomfort may vary depending on individual pain thresholds but is generally tolerable. Some clinics also offer numbing creams or cooling devices to minimize any discomfort during the procedure.

Q: How long is each underarm laser session?

A: The duration of each underarm laser session can vary, but generally takes between 15 and 30 minutes. Actual time may depend on factors such as the size of the treatment area and the individual’s hair growth density.

Q: Are there any side effects to underarm laser hair removal?

A: Laser hair removal is generally considered safe when performed by a trained professional. However, some common side effects may include temporary redness, mild swelling, or a sunburn-like sensation in the treated area. These side effects usually disappear within a few hours to a few days. In rare cases, there may be temporary pigment changes or blistering, but these are usually transient. It is important to follow the post-treatment care instructions provided by your practitioner to minimize potential side effects.

Q: How many laser sessions do I need to see results?

A: On average, most individuals require around 6-8 laser sessions for underarm hair removal. However, the exact number of sessions may vary depending on factors such as hair color, thickness, skin tone, and individual response to treatment. It is important to note that laser hair removal targets hair follicles in the active growth phase, so multiple sessions are required to treat hairs in different growth cycles.

Q: How long do the results of underarm laser hair removal last?

A: Laser hair removal provides lasting results. After completing the recommended number of sessions, many people experience a significant reduction in underarm hair growth. However, it is important to note that laser hair removal does not guarantee permanent hair removal. Some hair regrowth may occur over time, but it is usually finer and lighter in color. Maintenance sessions may be required once or twice a year to maintain desired results.

Q: Can I shave between underarm laser sessions?

A: Yes, you can shave between laser sessions. In fact, it is recommended to shave the treated area before each session to ensure that the laser energy is targeted at the hair follicles rather than the surface of the hair. However, it is important to avoid waxing, hair removal, or the use of depilatory creams as these methods remove hair follicles and can interfere with the effectiveness of laser treatment.
