Did you know that Laser hair removal is one of the most effective ways to reduce unwanted hair? In fact, its current market size was valued at around $1.13 billion. This implies the increasing demand for safe, long-lasting, and effective hair reduction, which is possible only with laser hair removal techniques.
However, the success of hair removal often depends on your hair growth cycle. So, the best thing to do is understand this cycle and know why you need multiple treatment sessions for complete removal.
Let’s discuss the hair growth cycle further and learn how it impacts the effectiveness of laser hair removal.
How Does the Hair Growth Cycle Work?
There are three stages in your hair growth cycle: anagen, catagen, telogen, and exogen. Each of them plays a key role in how your hair grows and affects the way laser hair removal sessions work. Let’s understand these phases of hair growth in more detail:
- Anagen Phase (2-7 Years)
This is the most active growth phase of your hair when the follicles remain within the skin. During this time, your hair is fully rooted, and the pigment is concentrated in the shaft. The same pigment absorbs the laser energy, which heats up and damages the follicle to prevent future hair growth.
- Catagen Phase (2 to 3 Weeks)
This is a very short, transitional phase in which your hair stops growing. The hair follicle begins to shrink during this time, and your hair is often pushed upward as it prepares to enter the next phase. The hair does not grow actively anymore, and the follicle begins to detach from the hair shaft.
- Telogen Phase (3 to 4 Months)
This is the resting phase when your hair stops growing completely, and the follicle remains inactive. Your hair may stay in the follicle until it eventually sheds, making room for new hair to grow.
- Exogen Phase (2 to 5 Months)
This shedding phase is an extension of the telogen stage, during which old hairs are shed from the follicle to make room for new growth. This is when you may naturally lose 50–100 hairs per day from the scalp. Since the follicle is either empty or in early development for new hair, this stage is mostly not responsive to laser treatment.
Why Does the Hair Growth Cycle Matter for Laser Hair Removal?
The effectiveness of laser hair removal depends on treating hair during the anagen catagen telogen phases of its growth cycle.
Laser hair removal often targets the anagen phase of your hair. That is why the pigment in the hair easily absorbs the laser's energy. However, all hair follicles are never in the same phase of the growth cycle at the same time. This means you require multiple laser hair removal sessions to target hair at different stages of growth. Let’s understand why:
Different Stages of Your Hair
Every hair is not in the anagen phase at a given moment. Some of your hairs may be in the catagen or telogen phase, too. This means they are not actively growing or embedded in the follicle. Laser hair removal is most effective in the anagen phase, which includes over 20–30% of your hair. Hence, multiple treatments might be needed to target hairs at different points in the cycle.
Hair Growth Varies by Area
Different areas of your body have different growth cycles. For instance, the hair on your legs may have a longer anagen phase than the hair on your upper lip. That is why certain areas of your body might need more hair regrowth cycle laser treatment sessions to achieve the desired result.
What Are the Benefits of Multiple Hair Removal Sessions?
You may need multiple laser hair removal sessions because of your hair’s growth cycle. Their additional benefits include:
- Better Hair Reduction: Laser sessions target your hair in its growth phase. This means you can get several hair follicles treated with multiple treatments.
- Long-Lasting Results: Hair regrowth becomes finer, lighter, and slower with repeated sessions. Over time, many people experience semi-permanent or near-permanent hair reduction.
- Full Coverage of the Treatment Area: Not all hairs are active at once. Multiple visits help catch those that were dormant or in a different growth phase during earlier sessions.
- Less Discomfort in the Long Run: Treatments often become faster and more comfortable because hair density reduces over sessions.
- Reduced Risk of Ingrown Hairs: Consistent laser sessions can decrease the chances of ingrown hairs and is a better alternative to shaving or waxing.
- Cost-Effectiveness Over Time: Laser treatments can be a bit expensive than other traditional hair removal methods. However, you will have fewer maintenance sessions in the future. This makes them an economical option for many.
- Customized Treatment Progress: You can easily adjust the laser settings based on your skin tone and hair thickness. Sometimes, results from previous treatments can also help to maximum effectiveness.
- Improved Skin Texture and Tone: Repeated sessions can make skin feel smoother and look clearer over time. Hair removal also reduces irritation from shaving or waxing in the long run.
- Consistent Results: A permanent hair reduction process prevents patchy areas. It ensures the hair removal process happens smoothly across the treated region in your body.
What Are the Factors That Affect the Success of Laser Hair Removal?
The hair growth cycle plays a key role in ensuring successful laser removal sessions. However, certain factors influence its effectiveness, like:
- Hair Color
A laser can easily target darker hair because it contains more pigment. However, fine or lighter hair may not be able to absorb as much laser energy. This often makes it harder to treat them.
- Hormonal Changes
Hormonal imbalances caused by polycystic ovary syndrome (PCOS) or pregnancy can affect your hair growth patterns. This may also make your hair more resistant to laser treatments.
- Skin Tone
Laser hair removal works best on individuals whose hair color and skin tone are quite different. However, you may require specialized laser types and settings, especially if you have a darker skin tone. This is usually done to avoid skin damage while still targeting your hair follicles effectively.
- Treatment Consistency
The effectiveness of laser hair removal sessions if you skip or delay the procedures. Always stick to the recommended treatment schedule to ensure more hairs are targeted in their active growth phase. In short, following the correct hair removal treatment duration leads to better long-term results.
Final Thoughts
If you are considering laser hair removal, then you must also understand your hair growth cycle. If your hair is in the anagen or growth phase, this process works in a better way. However, you may still need multiple laser hair removal sessions to target all hair follicles over time. It’s a highly effective procedure, but the results often depend on factors such as hair color, skin type, and the specific area being treated.

FAQs
- How many sessions for laser hair removal do I need?
Most people require between 6 to 8 sessions for optimal results, but the exact number depends on your hair type, skin tone, and the treatment area. Some individuals may need occasional maintenance sessions after the initial course.
2. Is laser hair removal safe for all skin types?
Yes, but the type of laser used matters. While traditional lasers worked best on light skin with dark hair, newer technologies such as Diode and Nd:YAG lasers can safely and effectively treat a wider range of skin tones when used by a qualified professional.
3. How long should I wait between laser hair removal sessions?
Sessions are spaced 4 to 6 weeks apart for facial areas and 6 to 8 weeks apart for body areas. This timing ensures the maximum number of hairs are in the anagen phase for each treatment.
