Full Legs Laser Hair Removal: How Many Sessions Will I Need?



1. How does laser hair removal work?



Laser hair removal is a cosmetic procedure aimed at removing body hair on various areas of the human body. The most commonly treated areas are the legs, underarms and bikini. However, more and more patients decide to undergo laser hair removal to remove their facial hair or even every single hair on their body. In essence, the procedure relies on a laser and color pigments present in the hair.



The laser targets pigments that are presents in body hair to send light energy down to the hair follicle. There, the energy turns into thermal energy, heating up the hair follicle so much that it damages it and prevent any further hair growth. Laser hair removal is only effective when the hair is in the anagen phase of the hair growth cycle. Indeed, it is the only time where the hair and the follicle connects. As a matter of fact, if the hair is another stage of growth, then the root does not connect to the follicle and the energy cannot reach it.



20% of a person’s hair is in the anagen phase of growth at any point of time. Thus, considering a margin of error, the laser will be able to target up to 18% of hair during one session. That is why patients need more than one session to remove all their hair. As hair growth is mostly stimulated by hormones, it is possible that being on a hormonal treatment (i.e. birth control or hormone therapy) or going through an intense hormonal change (i.e. pregnancy) interfere with the treatment. Patients may thus require extra sessions or a touch-up here and there.



2. Is laser hair removal permanent?



It is important to remember that full legs laser hair removal is not permanent. Being a relatively new hair removal method, few research has been done on it and there aren’t enough long-term samples to judge whether it is indeed permanent. So far, only electrolysis can be called a permanent hair removal method as approved by the FDA. However, electrolysis is a much longer, more painful and expensive process than laser hair removal.



However, laser hair removal can still be permanent. The results of the procedure will depend from one patient to another. Yet, most patients undergoing laser hair removal will see permanent hair growth reduction. Some will even never see a hair again. That’s why that, according to industry standards, laser hair removal can contribute to reducing hair growth by up to 90%. While some patients will need touch-up sessions once a year after their initial treatment, some will need a touch-up once every five years and some other not at all.



3. What factors impact the results?



The results of your full legs laser hair removal sessions will depend on many factors. Some, patients will have control over. Some, they won’t. Laser hair removal is widely known to work better on fair skin and dark hair. Thus, it is possible that dark skin may need more session. Indeed, the laser relies on the contrast between skin and hair to target the hair pigments. Dark skins usually do not have that contract.



Similarly, blonde hair on white skin are difficult to target. However, both can still undergo laser hair removal as improvement in laser technology allow to target light hair and work on dark skin. They might just need more sessions. The thickness of the hair may also affect the results. 



As mentioned above, hormone impact the hair growth cycle and may interfere with the treatment. Thus, patients on birth control or any other hormonal medication may need extra sessions. Similarly, it is recommended to stop taking some medicines such as antibiotics because they increase sensitivity, and thus, pain.



Finally, your personal routine in-between each full legs laser hair removal session will have an impact on your results. If you shave or pluck, you will interfere with the treatment and make it difficult to target the hair during sessions. Indeed, waxing remove both hair and root. Thus, the hair must grow again completely, which can take up to six weeks. Coupled with the hair growth cycle, it may reduced the number of hair that the laser can treat. Shaving also stimulate hair growth and patients should refrain from shaving as much as possible. Finally, it is recommended to avoid direct sun light and to wear a strong SPF at all time to protect the skin.



4. How many sessions of full legs laser hair removal will I need?



The industry standards want a basic full legs laser hair removal to include six sessions. However, most people need between eight and twelve sessions to see optimal results. Again, this will vary from one patient to another. Each individual is unique and so will be their treatment. Skin complexion, hair color, hair texture, past hair removal history, medication, may all impact the results of laser hair removal as well.



All patients are eligible for a free consultation prior to starting their treatment at Infinity Laser Spa. Thus they can ask as many questions as they have? The technician will also explain the procedure, give an estimation of how many sessions patients will need as well as a personalized quote. Needing eight sessions is absolutely normal. Patients may need to come back for a touch-up. 



Patients will start to see results early on in their treatment. Although not all patients will see hair growth reduction from the first session, they will start to see good results after three to four sessions. It is when approximately 50% of the hair has been treated. Be patient as you wait to see results and follow all your technician’s recommendations to ensure your maximize the results of your sessions.
