How does Laser Hair Removal work?

Lasers that are used for Laser Hair Removal are absorbed by Melanin. The GentleLASE laser system, a revolutionary long-pulse high energy Alexandrite Laser emits a beam of light that passes through the skin to the hair follicles where it is absorbed. The laser energy is transformed into heat.

This destroys the hair follicle leaving the surrounding skin unaffected. After a series of laser treatments the follicles become sterile which prevents the reproduction of further hair growth. This destroys the hair follicle leaving the surrounding skin unaffected. After a series of laser treatments, the follicles become sterile preventing the development of further hair growth in that follicle. Laser Hair Removal is a safe, effective and commonly used treatment, providing great results in the removal of unwanted hair in all areas of the body.

Our FDA approved laser is equipped with a Dynamic Cooling Device. Cryogen is sprayed onto the skin, cooling the upper layers and providing patients with increased comfort. This GentleLase laser system effectively and almost painlessly treats the unwanted hair without causing any damage to the skin.

How the laser works to safely destroy Hair Follicles

Laser permanently removes hair in follicles during the growth (Anagen) phase.  At any time, about 85% of our hair is in the growth stage and will be removed by Laser. During this stage, the hair is most receptive to Laser because it is rich in protein, keratinized cells and melanin. The amount of time the hair follicle stays in the Anagen phase is determined by our genetic make-up.

A hair’s Anagen phase may last for several years, with Anagen hairs representing about 85% of our hair. At the conclusion of the Anagen phase, the follicle enters the Catagen or transition phase and then the Telogen or resting phase when the hair begins to shed while the follicle is stimulated to begin a new cycle. Hair is not susceptible to Laser during the Transition and resting phases. Please see the City Laser Clinic page about the Stages of Hair Growth. The duration of these phases of hair growth varies from person to person and is affected by our basic genetic (DNA) make-up, age, health and gender.  Different hair colour and follicle shape also affects the timings of these phases.

As hair follicles move back to the growth phase they become susceptible to laser treatment and can then be removed permanently, hence the need for follow up visits to treat the follicles that were not in the growth (Anagen) phase during earlier visits.  Maintenance laser visits are also required to remove hair from new follicles that start to grow hair.  This is why we recommend 2 to 3 laser Maintenance visits each year.


Laser Hair Removal treatment is more effective with thick dark hair than it is with thin light hair. If you have naturally dark hair and dark skin you can still benefit from laser treatment for hair removal, however additional laser treatments are usually required to achieve satisfactory results. Laser treatments have been used for many years for a variety of medical and cosmetic procedures. CANDELA GentleLase laser, the most trusted name in the industry, has pioneered the development of some of the safest and most effective laser technologies and products available on the market today.

How Many Treatments?

At City Laser Clinic , we recommend at least 8 to 10 laser hair removal treatments, 6 weeks apart for a significant reduction of up to 75 -80 %. This does require your commitment to laser treatments every 6 weeks, or as otherwise assessed and advised by your City Laser Clinic laser therapist based on assessment of your hair and skin type. Please contact City Laser Clinic to arrange a FREE laser consultation to discuss a laser hair removal treatment plan that suits your needs with one of our trained, qualified and experienced laser hair removal staff.

Is Laser Hair Removal suitable for everyone?

The ideal candidate for Laser Hair Removal is a person with light skin and dark hair. People with light skin and dark hair will receive the best results (up to 75 – 80% reduction after 6 to 10 treatments). People with dark skin and dark hair can still be treated, but may need more laser treatments.

People with blonde, red and grey hairs cannot achieve significant hair removal with available laser machines. To achieve the best results, City Laser Clinic uses the CANDELA GentleLase – Genuine Laser for hair removal. The CANDELA GentleLase delivers a laser beam on a specific wavelength most suited to hair removal. The laser energy that is used is more effective than other processes and assures safe destruction of the active (Anagen) hair follicles in the treated area.
