Is Laser hair removal permanent?

Laser hair removal is one of the most sought after non-surgical treatments within the aesthetics industry. Laser hair removal offers a permanent reduction in hair growth; however, it cannot be classed as permanent hair removal.

Laser hair removal is usually purchased in packages as a single treatment may target some of the hair follicles during one session, however only a certain amount of hair will be in the active growth phase known as the anagen hair growth cycle. Having a package of 6-12 laser hair removal sessions, you can get up to 80-90% of hair reduction. Each session will target the hundreds of hair follicles within the skin which are in the active growth phase. Due to the nature of the hair growth cycle, it is impossible to know which hair follicles are in the active phase and which are in the resting phase. This is the reason why the treatment packages are recommended with 6 -12 as a minimum.

Laser hair removal works on the principle of selective photo-thermolysis which will have a chromophore meaning the target within the skin. For laser hair removal the target is the melanin with the hair follicle. The laser penetrates the skin causing thermal damage to the hair follicle the surrounding skin is not impacted in any way resulting in slower regrowth and finer hair.


Results can vary from person to person, this has several factors which include the skin type, hair density, medical conditions, medications, and the client’s background. Laser hair removal is suitable for all Fitzpatrick’s skin types. Some people will see results sooner, whilst others may see results on their 5or 6 session. Some clients may need more sessions than others this all depends on different factors. Following a course of 6-12 sessions the hair growth will be slower, hair will be finer, skin will be smoother and most importantly it will reduce the amount of time spent shaving.

Medication and Health conditions: 

These will be discussed within your initial consultation with the therapist. The therapist will go through any existing health conditions and medications within the medical history section of your consultation. It is important to give accurate information during the process. Any health condition such PCOS and Hirsutism the therapist will give you information on the how the laser will work, how many sessions will be required and discuss the realistic expectations from laser hair removal.


Treatment packages will be recommended as 6-12. After the initial 6-12 sessions maintenance treatments will be required to keep up with the treatment’s effectiveness. This all depends on the clients results and expectations. The maintenance treatments will help you stay hair free for longer. Top up treatments may be between 1-3 times a year however this is assessed on an individual basis.
