How Long Does Hair Fall Out in Laser Hair Removal?


If you want long-lasting hair reduction treatment, laser hair removal has shown promising results. It involves targeting hair follicles with focused light, gradually destroying them, and inhibits hair growth.

This article aims to discuss hair fall-out post-treatment, and touch some concepts of laser hair removal misconceptions.

How Laser Hair Removal Works

Melanin (produced by melanocytes, which are cells of the skin) is the one targeted by laser. The latter produces heat, thus destroying melanin in the process. As a result, it inhibits future hair growth, and leads to longer-lasting solutions for hair removal.

Post-Treatment Shedding

After a session of laser hair removal, hair on the treated area will start to shed. It is a process that typically occurs around 1-3 weeks post-treatment. There are cases when hair grows back initially but eventually it will shed. Thus, the treated area will appear smooth and hair-free.

Factors Affecting Shedding

Hair color, thickness, and target area are factors that can affect shedding. This sometimes requires a few more treatments to achieve optimum results. For instance, darker and thicker hairs tend to respond better to this form of hair removal. There are people with lighter or finer hair that may need several more treatments.

Results and Expectations

You need to understand the limitations of laser hair removal. While it can be expected that it can achieve 70% to 90% reduction of hair, it cannot be truly emphasized that some treatments may not achieve this at all.

However, eventually, these people who are somewhat resistant to laser hair removal can respond well with repeated treatments. Or, when they avail of maintenance treatments so they, too, can achieve reduced hair growth.

Common Myths

Common misconceptions about laser hair removal include the following:

  • Pain-free
  • Instant results
  • Suitable for all skin and hair types

In reality, the procedure can cause temporary discomfort, requires multiple sessions before results are visible, and is not appropriate for all.


In summary, laser hair removal is an effective and popular method for long-lasting hair reduction. Understanding the post-treatment shedding process, factors affecting shedding, and having realistic expectations are essential for successful results.


While some may argue that laser hair removal is not a permanent solution due to the need for maintenance treatments, it is important to note that these treatments are typically required less frequently. Hence, the term “maintenance”. 

With maintenance treatments, individuals can continue to enjoy the benefits of smooth, hair-free skin even if new hair growth occurs due to hormonal changes or genetic factors.
