How Long Does It Take to See Results from Underarm Hair Removal?

How Long Until I See Smooth Underarms?

  • I start noticing finer, lighter hair regrowth within 2-4 weeks after my first session
  • For full results, I typically need 6-8 treatments spaced 4-6 weeks apart
  • This allows the laser to target hairs in different growth cycles
  • After my final session, it takes around 4 more weeks to see maximum hair reduction
  • Only 20% of my underarm hair is in the active growth phase at any given time
  • The laser can only disable follicles during this active anagen phase
  • So I need several sessions to catch all the hairs in their growth cycles

Factors Affecting Hair Removal Results


In my years in the aesthetics industry, I’ve talked to many people about underarm hair removal. They often ask, “How long until I see results?” I’ve seen first-hand how treatments work and talked with experts too. So, I can share some insights.

Underarm hair removal is a common aesthetic procedure that many individuals opt for to achieve smooth underarms. The process involves eliminating unwanted hair from the underarm area. People choose different methods such as shaving, waxing, or using hair removal creams. However, for a more permanent solution, laser hair removal for underarms is a popular choice.

The process of underarm hair removal can differ from person to person. Some see quick results, while others wait a bit longer. It depends on the method and your hair type.

In the article below, I’ll dive deeper into this topic. We’ll look at what affects these results and what you can expect. This way, you’ll have a clear idea before starting your journey.

Overview of Underarm Hair Removal

Underarm hair removal can be achieved through various methods, each with its distinct pros and cons. Shaving is fast and painless, but only removes hair temporarily. Waxing removes hair from the root, leading to longer-lasting results.

Laser hair removal is a more permanent solution that targets hair follicles, reducing hair growth over time.

When undergoing underarm hair removal, several factors can impact the results. The density of hair, skin colour, and the chosen treatment option can affect the effectiveness and duration of the procedure. In some cases, individuals may experience ingrown hair or slower hair growth post-treatment, influencing the overall outcome.

Each laser hair removal treatment can remove up to 25% of hairs that are in an active (anagen) stage. Treatments are typically performed every 8-10 weeks and are continued until the desired reduction is achieved.

Types of Underarm Hair Removal Treatments

One of the most sought-after methods for underarm hair removal is laser treatment. Laser hair removal targets hair follicles using a concentrated beam of light. This heats up the follicles and prevents future hair growth. This leads to a reduction in unwanted hair and results in smoother underarms over time.

Compared to non-laser treatments like waxing or depilatory creams, laser hair removal may offer more long-lasting results. Laser treatment may be more expensive at first, but its long-lasting results and effectiveness make it a popular option for people who want to permanently reduce hair.

So, when is the best time to schedule your laser hair removal session? While there’s no one-size-fits-all answer, it might be beneficial to plan your sessions around your menstrual cycle to maximize the treatment’s effectiveness. Always consult with your skincare professional for personalized advice.

Timeline for Seeing Results

When opting for laser hair removal for underarms, individuals can expect to see a range of results over time. Understanding the timeline for these results can help manage expectations and plan for maintenance.

Immediate Effects after Treatment

After a laser hair removal session, you might experience some immediate effects like a bit of redness or swelling in the area that was treated. These effects typically subside within a few hours to a day, and individuals may already experience a smoother underarm appearance.

Gradual Reduction in Hair Growth

Over the following weeks and months post-treatment, there will be a gradual reduction in hair growth. Some hair may continue to shed, and the regrowth will be finer and sparser. This phase showcases the effectiveness of laser treatment in targeting and inhibiting hair follicles.

Achieving Permanent Hair Reduction

Multiple sessions of laser hair removal can significantly reduce hair growth, leading to long-lasting results for most people. While complete hair removal may not be possible for everyone, noticeable permanent hair reduction can be accomplished, providing smoother underarms.

Managing Expectations and Maintenance

After getting laser hair removal for your underarms, it’s important to have realistic expectations about the results and understand what maintenance is needed to keep the outcomes. The following factors play a role in managing expectations and ensuring optimal results.

Frequency of Sessions for Optimal Results

The frequency of laser hair removal sessions is crucial for achieving optimal results. Typically, a series of sessions spaced several weeks apart is recommended to target hair follicles in different growth phases adequately. Consistency in treatment sessions is key to maximizing the effectiveness of laser hair removal.

Post-Treatment Care for Underarms

Proper post-treatment care is essential in maintaining the results of laser hair removal for underarms. To get the best result, you should avoid the sun, moisturize your skin, and follow any instructions given by your treatment provider.

Comparing Laser Hair Removal with Other Methods

Comparing laser treatment with non-laser methods like waxing, shaving, or depilatory creams can help people make an informed decision about underarm hair removal. Knowing the differences in how long hair removal methods work and their possible side effects can help choose the best method for smooth underarms.
