Permanent Hair Removal Through Lasers

True or False?

The CANDELA GentleLase laser machines used by City Laser Clinic do achieve permanent hair reduction on treated areas. You can expect to achieve between 80% to 95% hair reduction with a CANDELA GentleLase laser Hair Removal treatment program. These results will be influenced by factors including your skin type, hair colour and hormones. We also advise 2 to 3 maintenance laser visits a year as being necessary to manage new hair and growth from follicles not able to be treated during earlier visits. Laser Hair Removal treatment permanently removes hair in follicles during the hair growth (Anagen) phase. At any time, about 85% of hairs are in the growth stage and will be removed by Laser.

During Anagen stage, the hair is most receptive to Laser as it is rich in protein, keratinized cells and melanin.

How long the hair follicle is in the Anagen, (growth) phase is determined by our individual 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 hair follicles enter 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 Hair Removal treatment during the transition and resting phases. The duration of these phases varies from person to person and is affected by individual genetic (DNA) make-up, age, health and gender. As hair follicles move back to the growth phase they become susceptible to Laser Hair Removal treatment and can then be removed permanently, this requires follow up visits.

Maintenance laser visits are required to remove hair from new follicles that develop and start to grow hair. This is why we recommend 2 to 3 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 natural dark hair and dark skin you can still be benefit from laser treatment for hair removal, however additional laser treatments are usually required to achieve satisfactory results.

Why does hair seem to regrow in the treated area?

There are two common reasons that hair grows in an area that has been treated by Laser. Firstly, as described above, Laser hair removal treats and removes hair in the Anagen (growth) phase; it is not effective on hairs during their Catagen or transition phase or their Telogen or resting phase when the hair begins to shed. Maintenance laser hair removal visits are directed at treating hears as they come back to the Anagen (growth) phase. Hair does not grow from the follicles that have been treated and destroyed by the laser; the growth is from the hair follicles that were in transition (Catagen) and resting (Telogen) phases during the treatment. The duration of the hair growth cycle varies in different parts of the body, and so the follow up treatment schedule must allow for the time it takes the hair to move to the Anagen (growth) phase during which it can be effectively treated and the follicle destroyed. The following table Indicative table of Hair growth:

Scalp ArmsPubic Area
Anagen (Growth) phase2 to 3 years (sometimes much longer)18 to 24 months6 to 8 months
Catagen (shrivelling) phase2 to 3 weeks6 to 10 weeks6 to 10 weeks
Telogen (resting) phaseAbout 3 monthsAbout 3 MonthsAbout 5 Months

The duration of these phases varies depending on our genetic (DNA) make-up, as well as age, and health. This hair growth schedule reveals why a maintenance program of about 3 months is required for most parts of the body, whilst some parts such as the pubic area (Brazilian) require follow up laser treatments for up to 8 months, and sometimes longer; so as to treat hair that was in the Catagen and Telogen phases during earlier treatments.

New Hair starts growing due to life changes

This is the second common reason for new hair in treated areas. Hair follicles are activated by hormonal changes (such as puberty, pregnancy, and ageing). Some medical conditions such as Polycystic Ovary (PCOS) will also promote hair growth as will exposure to some chemicals. As we age, hair grows in new parts of our bodies and also grows thicker in other parts – and thins in other parts. Male Baldness is a common and visible evidence of natural hair thinning. Laser hair removal treatment cannot prevent hair growth of hair from follicles that have not yet formed; that are programmed by our DNA to form months or years after Laser Hair Removal treatment. Totally new hairs may grow in the body area that was treated, after permanent removal of hair existing at the time of laser treatment. It is important to consider that whilst new hair may grow, the hair will not be as thick as it would have been without the Laser Hair Removal treatment of the earlier growth – and the later growth can be effectively treated by Laser, so as to maintain the desired appearance.
