Have you noticed that many clinics advertise laser hair removal as a solution for achieving permanent hairlessness? Yet, it's not uncommon to see individuals returning for additional laser sessions even after completing their initial treatments. This raises an important question: What is the true nature of the permanence associated with laser hair removal, and why do so many people pursue follow-up treatments?
If this topic piques your curiosity, you’ve come to the right place. In this article, we will delve into the results of laser hair removal and assess whether this procedure is sufficiently safe for multiple sessions.
1. What Are the Preparation, Procedure, and Post-Treatment Care for Laser Hair Removal?
The effectiveness and safety of laser hair removal largely hinge on your commitment to pre-treatment, treatment, and post-treatment care.
Preparation
Preparing for laser hair removal primarily involves selecting a reputable laser provider and ensuring your skin is adequately prepped. This entails ensuring that your skin is free from dead cells, impurities, and excess oils before undergoing treatment. Additionally, it’s crucial to avoid direct sun exposure, refrain from plucking hair from the roots, and maintain hydration. Lastly, be sure to shave the treatment area prior to your appointment.
Procedure
Before the procedure, discuss your expectations, pain tolerance, and any skin sensitivity with your doctor. The treatment itself generally involves applying a local anesthetic to the area, placing protective goggles over your eyes, and then carefully directing the laser at the treatment site.
A detailed explanation of the laser hair removal procedure can be found in a medical review published by the Mayo Clinic [1].
Post-Treatment
Following a laser hair removal session, your skin may become sensitive and more vulnerable to damage. Therefore, it's essential to take care of your skin as you prepare for subsequent sessions. This includes avoiding hot baths, sun exposure, skincare products that contain harsh chemicals, and any scrubbing. Instead, opt for cold showers, gentle products, and loose-fitting clothing.
2. Who Is a Good Candidate for Laser Hair Removal?
If your skin tone ranges from fair to brown and your hair is dark, you are generally a suitable candidate for laser hair removal treatments. Additionally, advancements in laser technology have made it possible for individuals with colored hair and darker skin to benefit from this procedure.
Moreover, laser hair removal is particularly advantageous for those dealing with conditions such as PCOS, hypertrichosis, and hirsutism. A clinical trial highlights the effectiveness of laser hair removal for women experiencing hirsutism [2].
3. Who Should Avoid Laser Hair Removal?
Despite its many benefits, laser hair removal is not suitable for everyone. Individuals with cold sores, viral infections, tattoos, keloid scars, bleeding disorders, sunburned skin, skin cancer, or active acne should postpone their laser sessions until their conditions improve.
Furthermore, it is advisable to steer clear of laser hair removal during pregnancy. The contraindications associated with this treatment have been thoroughly discussed in an informative article by the UK Health Center [3].
4. Is Laser Hair Removal Safe?

It is essential that your skin is compatible with the laser and not listed among the contraindications mentioned earlier. While mild to severe side effects such as redness, inflammation, discomfort, skin dryness, blisters, and crusting may occur, these can often be managed through proper aftercare.
The efficacy and safety of the ND-Yag laser for hair reduction have been documented in a research article published in the Minia Journal of Medical Research [4].
5. How Many Treatments Are Necessary?
At any given time, hair exists in various growth stages, including the actively growing anagen phase, the transitional catagen phase, and the resting telogen phase. Laser treatment is most effective on hair that is in the anagen phase.
The effectiveness of your treatment will largely depend on the proportion of hair present in the anagen phase during your sessions.
Additionally, the number of initial treatments required for laser hair removal can vary based on the specific body part being treated, hair growth patterns, hair thickness, and the underlying reason for excessive hair growth. On average, 4 to 6 sessions can lead to over a 90% reduction in hair growth.
A study conducted across two centers illustrated the outcomes of laser hair removal within 3 to 5 treatments involving 948 patients [5].

6. Is Laser Hair Removal Permanent?
Unfortunately, laser hair removal does not provide permanent results as many might expect. Only electrolysis offers a truly permanent solution by targeting individual hair follicles.
In contrast, while lasers can effectively destroy some hair follicles, they may also induce a resting phase in others. Hair follicles that enter this resting phase can become active again after a certain time, leading to hair regrowth.
Additionally, some of the destroyed follicles may regenerate, resulting in more unwanted hair. Consequently, the results of laser hair removal can last anywhere from a few months to a couple of years, depending on follicle activity.
7. How Often Should I Schedule Follow-Up Treatments?
The frequency of follow-up sessions for laser hair removal is dictated by the rate of hair regrowth. Therefore, once you observe that your hair is beginning to regrow and you wish to address it again, you can schedule additional treatments. Typically, individuals require 2 to 3 follow-up sessions annually.
An article by Healthline elaborates on the varying needs for laser hair removal follow-ups [6].
