What Is Laser Hair Removal?

Unwanted body hair can be a constant hassle, leading many individuals to seek effective and long-lasting hair removal solutions such as shaving, waxing, and laser energy. Laser Hair Removal is a non-invasive treatment using lasers and selective photothermolysis, targeting hair follicles. The lasers’ energy, through selective photothermolysis, is absorbed by the melanin in the hair, generating heat that damages the hair follicle. This damage from laser energy inhibits the follicle’s ability to produce new hair, leading to adverse effects and a reduction in hair growth over time due to selective photothermolysis.

The process of Laser Hair Removal, also known as selective photothermolysis, involves lasers directing laser beams at the targeted follicle area, where the light energy penetrates the skin and is absorbed by the melanin in the hair. This causes the hair follicles to heat up and become damaged. Unlike other hair removal methods like shaving or waxing, lasers target the root of the hair follicle, resulting in longer-lasting effects. Over a series of laser sessions, this procedure can significantly reduce hair growth in patients and, in some cases, prevent it altogether.

Is Laser Hair Removal Permanent?

Laser Hair Removal is often considered a permanent hair removal solution with many individuals experiencing hair reduction after completing a series of Laser Hair Removal sessions.

The effectiveness and longevity of Laser Hair Removal results can vary depending on factors such as:

Hair Color & Skin Type: Laser Hair Removal tends to be most effective on individuals with light skin and dark hair. The contrast between the hair color and skin tone allows lasers to better target the hair follicles. People with lighter hair colors or darker skin tones may experience less effective results, as the laser’s energy may be less absorbed by the hair follicles.

The technology behind laser hair removal has advanced significantly, with newer lasers being able to treat a wider variety of skin tones and hair colors. Despite these advancements, the basic principle remains the same: the laser is most effective when there is a stark contrast between the hair color and skin tone. This allows the laser to target the hair follicles more precisely without damaging the surrounding skin.

Hormonal Factors: Hormonal changes caused by pregnancy or menopause can influence hair growth patterns. Hormonal imbalances may result in new hair growth, even after successful laser hair removal treatments.

It is important to note that while laser hair removal can significantly reduce hair growth, it may not be able to completely eliminate hair growth caused by hormonal changes. Individuals undergoing treatment for body hair should discuss their medical history, hair follicle, and any hormonal conditions with their practitioner to set realistic expectations and develop an effective treatment plan.

Treatment Area: Certain areas of the skin may respond differently to Laser Hair Removal. Areas with coarser hair, such as the bikini area or underarms, may require more sessions to achieve desired results. Some areas of the skin may also have more resistant hair follicles, leading to slower hair reduction.

The responsiveness of different areas to laser hair removal can be attributed to the density and thickness of the hair follicles. Areas with dense, coarse hair tend to absorb more laser energy, resulting in more effective treatment. However, these areas may also require more sessions due to the resilience of the hair follicles. On the other hand, areas with finer hair may respond quicker but might require touch-ups to maintain smoothness.

Number Of Sessions: The number of Laser Hair Removal sessions required to achieve optimal results varies from person to person. Most individuals need multiple sessions, typically spaced a few weeks apart, to target hair during different growth cycles.

Hair grows in cycles, including the growth phase (anagen), the transitional phase (catagen), and the resting phase (telogen). Laser hair removal is most effective during the anagen phase when the hair is actively growing. Since not all hairs are in the same phase at the same time, multiple sessions are necessary to target all the hair follicles effectively. Typically, six to eight laser sessions are recommended for most individuals to achieve significant hair reduction.

Post-Treatment Maintenance

To maintain the results of Laser Hair Removal, periodic maintenance sessions may be necessary. After completing the initial series of laser treatments, individuals may need touch-up sessions every six to twelve months to address any new hair growth that may occur.

Maintenance sessions, including laser treatments, are essential to keep the skin smooth and hair-free. These sessions help manage any new hair growth and ensure that the results remain consistent over time. Factors such as hormonal changes, weight fluctuations, and even certain medications can trigger new hair growth, making these touch-up sessions a crucial part of the hair removal process.


Laser Hair Removal is an effective method for long-term hair reduction, providing many individuals with smoother, hair-free skin. While it may not guarantee permanent and complete hair removal, laser hair removal offers substantial hair reduction results. The longevity of the effects varies from person to person, influenced by factors such as hair color, skin type, hormonal influences, treatment area, and laser.

To maximize the benefits of Laser Hair Removal, it is essential to undergo treatments at a reputable clinic with experienced practitioners. A personalized laser treatment plan and proper post-treatment maintenance will help individuals achieve the best and longest-lasting results for permanent hair removal.
