Introduction
As an Aesthetic Director with a deep understanding of skin and hair biology, I’ve often been asked about the intricacies of laser hair removal.
It’s a common misconception that one session is enough to achieve permanent hair reduction. However, the science behind this technique is more nuanced.
Understanding the Science of Laser Hair Removal Sessions
From my experience and ongoing research, I’ve found that the number of sessions required can vary depending on individual factors like hair density, color, and the area being treated. It’s a process that requires patience and understanding of the biological processes at play.
This article will share with you the reasons to why laser hair removal requires multiple sessions for effective permanent hair reduction.
Reason 1: Hair Growth Cycle
If you’ve ever wondered why one laser hair removal session isn’t enough to zap away all unwanted hair, the answer lies in our hair growth cycle, as explained by Philip Kingsley. Our hair grows in three stages: Anagen, Catagen, and Telogen.
Anagen Phase
The Anagen phase is the active growth phase of hair follicles. This is when the hair is growing in size and length, and it’s the perfect time for laser hair removal. Why? Because the laser targets the pigment in the hair follicle, and during the Anagen phase, the follicle is rich with this pigment.
Catagen Phase
Next comes the Catagen phase, a short transitional period where the hair stops growing and the hair follicle shrinks. Since the hair is no longer actively growing, it’s harder for the laser to target the follicle effectively during this phase.
Telogen Phase
Finally, we have the Telogen phase. This is the resting phase where the hair falls out and a new hair begins to form. During this phase, the old hair is detaching from its blood supply and the follicle is getting ready for the next Anagen phase.
Because laser hair removal is most effective during the Anagen phase, multiple sessions are needed to catch each hair as it comes into this phase. So, while it might seem like a hassle to go back for several sessions, remember that it’s all part of the process to ensure effective and long-lasting results!
Reason 2: Individual Differences
Just like how every individual is unique, the number of laser hair removal sessions required can also vary greatly from person to person. This is due to individual differences such as hair color and skin type.
Firstly, let’s talk about hair color. Darker hair absorbs more laser energy than lighter hair, making it easier to treat. This means that if you have dark hair, you might see quicker results compared to someone with lighter hair. On the flip side, individuals with lighter hair might require more sessions to achieve their desired results.
Skin Tone Matters: Why Darker Skin Needs Laser
Next, we have skin type. Laser hair removal works by targeting the pigment in the hair follicle. However, the laser can also be attracted to the pigment in the skin. This means that individuals with darker skin tones might require more careful treatment to avoid damaging the skin, which could potentially lead to more sessions.
So, while it might seem frustrating to need more sessions than your friend, remember that it’s all part of the process to ensure safe and effective results. After all, when it comes to laser hair removal, it’s not a one-size-fits-all situation!
Reason 3: Treatment Area
The size and location of the treatment area can greatly influence the number of laser hair removal sessions required. Let’s break it down.
Firstly, the size of the treatment area plays a significant role. Larger areas, like the legs or back, have more hair follicles to treat. This means they typically require more sessions compared to smaller areas like the upper lip or underarms.
Tailoring Laser Sessions to Your Hair Growth Rhythm
Secondly, the location of the treatment area can also affect the number of sessions. This is because hair growth rates vary across different parts of the body. For example, hair on the scalp grows faster than hair on the arms or legs.
As a result, areas with faster hair growth may require more sessions to catch each hair in the Anagen phase (the ideal phase for laser hair removal).
The average plastic surgeon’s fee for laser hair removal was $389 in 2020, according to the American Society of Plastic Surgeons.
Reason 4: Safety Considerations
Safety is paramount when it comes to any cosmetic procedure, and laser hair removal is no exception. This is where the need for multiple sessions comes into play.
Attempting to remove all hair in one session can be risky. High energy levels are needed to target and destroy all hair follicles at once, which can increase the risk of skin damage, including burns and pigmentation changes.
Moreover, a high level of discomfort or pain may be experienced during the procedure due to the intense energy used.
Why Multi-Session Laser Works Best
On the other hand, spreading the treatment over multiple sessions allows for lower energy levels to be used in each session. This not only minimises the risk of skin damage but also makes the procedure more comfortable for the patient. Each session targets a portion of the hair follicles, ensuring that all are effectively treated over time without overwhelming the skin.
In addition, multiple sessions allow for the treatment to be tailored to the individual’s response. The specialist can monitor the progress and adjust the treatment parameters if necessary, ensuring optimal results while prioritising the patient’s safety.

Reason 5: Long-Term Effectiveness
It’s a common misconception that one session is enough to achieve permanent hair reduction. However, the science behind this technique is more nuanced.
Laser hair removal targets the melanin in hair follicles using a concentrated beam of light. This light is absorbed and transformed into heat, damaging the follicles and inhibiting future hair growth.
Laser Hair Removal Targets the Right Hairs at the Right Time
The critical aspect to understand here is the hair growth cycle, which consists of different phases: anagen (growth), catagen (transition), and telogen (resting).
At any given time, your hair follicles are in various stages of this cycle. The laser is most effective on hair in the anagen phase, as this is when the hair is actively growing and the pigment is most abundant.
However, not all hairs are in this phase simultaneously. This is why multiple sessions are necessary – to catch each hair in its growth phase over time.
How Often Should You Have Laser Hair Removal?
Laser hair removal is usually performed with several weeks or months apart, but enough time should be allowed for hairs to pass through the different growth stages.
If you do not cater for or leave enough weeks between sessions, hairs in the treatment area may not be in the anagen phase and the treatment might not be effective.
Four to Six Week Gap is the Best
Based on overall research, about four to six weeks is the best time gap to allow the hairs to cycle in and out of the anagen phase.
At Wellaholic, we recommend customers to follow up on their hair removal sessions every four weeks. Session length varies based on the size of the target area, too, so broad men with unwanted back hair can expect longer treatments than women looking to smooth their bikini line.
Conclusion
In the journey towards smooth, hair-free skin, understanding the process of laser hair removal is key. As we’ve discussed, there are several reasons why this treatment requires multiple sessions:
- Hair Growth Cycle: Laser hair removal targets hair in the Anagen phase, and multiple sessions ensure all hair follicles are treated as they enter this phase.
- Individual Differences: Factors like hair color and skin type can affect the number of sessions needed.
- Treatment Area: The size and location of the treatment area can influence the number of sessions.
- Safety Considerations: Multiple sessions allow for lower energy levels to be used, reducing the risk of skin damage and making the procedure more comfortable.
- Long-Term Effectiveness: Multiple sessions can lead to longer-lasting results compared to other hair removal methods.
While it might seem like a lengthy process, remember that each session brings you one step closer to achieving your desired results. And as always, it’s important to consult with a professional for personalized advice. They can assess your individual needs and guide you through the process, ensuring you get the most out of your laser hair removal journey. Here’s to smooth, hair-free skin!
Frequently Asked Questions (FAQ)
How does the thickness of hair affect the number of laser hair removal sessions needed?
Thicker hair absorbs more laser energy, often requiring fewer sessions for effective removal. Conversely, finer hair may need more sessions as it absorbs less energy.
Are there any specific post-treatment care instructions to follow after each laser hair removal session?
Yes, post-treatment care includes avoiding sun exposure, not using saunas or hot tubs for a few days, and applying aloe vera or a soothing lotion to reduce any irritation.
How does laser hair removal on hormonal areas like the face or bikini line differ from other body parts?
Hormonal areas like the face or bikini line may require more sessions due to denser hair growth influenced by hormonal fluctuations, compared to less dense areas like the arms or legs.
Is there a recommended age to start laser hair removal for optimal results?
While there’s no strict age limit, starting laser hair removal in your late teens or early twenties can be optimal, as hair growth patterns have typically stabilized by this age.
How does the color of the hair affect the number of sessions required for laser hair removal?
Darker hair, which has more melanin, typically responds better to laser treatment and may require fewer sessions. Lighter hair lacks melanin and often needs more sessions for effective removal.
What happens if I stop laser hair removal after 2 sessions?
Stopping laser hair removal after just 2 sessions may lead to partial results. Some hair follicles will be treated, but many will remain unaffected, likely resulting in uneven hair reduction and regrowth.
Is 3 sessions of laser hair removal enough?
Generally, 3 sessions of laser hair removal are not sufficient for complete results. While some reduction will be noticeable, most individuals require 6 to 8 sessions to effectively target all hair follicles in their growth cycles.
