How Long Does Laser Hair Removal Last?


Hair-free skin has been a universal desire for centuries. Removal of unwanted hair to achieve smooth and hair free skin has introduced various techniques in the realms of cosmetology and medicine. Among many other traditional and modern techniques laser hair removal treatment has made its significant place as the most effective treatment and long-lasting effects.

Laser Hair Removal

Laser hair removal is a cosmetic procedure in which a concentrated beam of light called a laser is used to damage the hair follicles to reduce and remove unwanted hair. The melanin in the hair follicles got heated up by absorbing the energy produced by laser technique and thus damaging the follicle delaying or even ceasing future hair growth.

Though the process of hair removal is considered highly effective and safe the results vary from person to person. Laser treatment may not guarantee permanent or complete hair removal for everyone. But here it is worth noticing that if the laser does not remove hair growth then it makes the hair lighter and finer than before. When considering hair removal, experienced and professional experts must be consulted first.

They determine whether in a specific case, the laser treatment would be appropriate or not to bring the desired changes. How long the laser hair removal results will last vary from person to person and may be caused by several different factors. It is essential to understand the complexities and complications of the process of laser hair removal.

How Long Does Hair Removal Last?

After the first five or six sessions, most of the individuals experience a prominent reduction in hair growth. Some got permanent hair growth removal whereas others feel the need for some more sessions to keep the hair growth in check. The longevity of hair removal treatment depends on many factors including hair color, skin color, hair thickness, hormonal influences, and genetics. Let’s discuss each of the factors in detail.

Factors Affecting Hair Removal Duration:

Hair Color and Type:

The effectiveness of the treatment largely depends on the contrast between the color of the hair and the skin. The treatment gets maximum success in individuals having light skin with dark and gritty hair. The laser energy is absorbed by the hair follicles, lighter hair colors do not respond effectively to the laser energy and thus affect the duration of the results and longevity of the treatment.

Skin Type:

As the darker colors respond to the laser treatment effectively so individuals having fairer skin and darker hair usually experience better results whereas people with darker skin tones may need specialized devices to prevent skin damage. In this case, the Fitzpatrick scale is considered the best to determine the best laser treatment for various skin types.

Hormonal Influences:

Hormonal fluctuations have a great influence on the results of laser hair removal treatments. For instance, individuals during pregnancy, menopause, or conditions like polycystic ovary syndrome (PCOS), usually undergo hormonal imbalances. They may have new hair growth even after the successful initial sessions.


Genetic factors also play an important role in determining the thickness, density, and growth cycle of an individual’s hair. By nature, some have hair that is strong and resists the laser treatment affecting the duration of laser hair removal treatment results.

Treatment Area:

Different body areas have different hair growth abilities, patterns, and characteristics. Facial hair needs extra maintenance sessions for effective hair removal. Moreover, the areas having finer and lighter hair growth may need some extra sessions for permanent hair removal.

Number of Sessions:

Laser hair removal sessions are not administered in a fixed number. Rather multiple sessions can be arranged to fix the desired issue. Depending on the individuals and treatment area the sessions can range from 6 to 8 or even more. The laser treatments also facilitate individuals who need occasional maintenance sessions to keep hair growth in check.

Maintenance and Longevity:

The longevity and efficacy of laser hair removal results vary from person to person relying on several factors. Some people may enjoy permanent hair reduction while others may experience hair regrowth sooner. Maintenance sessions that are fewer in number than the initial sessions are also used to target the new hair growth that an individual may face even after the initial sessions due to hormonal changes, genetics, and lifestyle.


To sum up the above detail, the longevity of laser hair removal treatment results is greatly influenced by a complex interplay of factors, including hair and skin color, genetics, hormonal influences, treatment area, and the number of sessions. Though the very approach offers significant hair reduction mostly permanently still it is essential to opt for best laser hair removal treatment with realistic expectations.

Consulting with an experienced practitioner, discussing your requirements, medical history, and following the practitioner’s advice are the steps leading to 100% results.
