Laser hair removal is a great way to say hello to silky smooth skin and “au revoir” to the hassles of frequent shaving, waxing, or plucking. It is one of the most effective, long-lasting and relatively painless ways to remove unwanted hair. Because of this, it has become very popular all around the world.

To get the best results you’ll need to go for multiple sessions, with a waiting period between sessions to give any remaining hair time to grow back so they can be targeted by the laser in the next session. How long you should wait depends on several factors which we will explore below. 

How Long Should I Wait Between Each Laser Hair Removal Session?

The interval between laser hair removal treatments depends on the hair growth cycle specific to each body area. Waiting an appropriate length of time between sessions ensures the treatment effectively targets hair follicles in their growth phase, leading to a significant reduction in hair over time. Your technician will assess regrowth patterns and adjust intervals based on individual progress.

Face and Neck

4 – 6 Weeks

The facial region, including the upper lip and chin, typically has a fast growth cycle due to its higher hair follicle density and hormonal influences. This rapid growth necessitates a shorter interval between treatments, usually around four weeks. However, areas with slower regrowth, such as the cheeks and jawline, may need slightly longer intervals. Since facial hair can be hormonally influenced, particularly in women, some might require more frequent sessions to account for fluctuating regrowth patterns.

Bikini Area

4 – 6 Weeks

The bikini area has hair that is usually thicker and coarser compared to other regions. Because of this texture and the region’s moderate growth rate, a four to six-week interval between sessions is optimal. This timing ensures new follicles have entered the active growth phase, making them susceptible to the laser’s energy. Variability in hormonal cycles and hair density might necessitate adjustments to the interval between maintenance laser treatments, so it’s essential to monitor regrowth carefully.


4 – 6 Weeks

Underarm hair generally has a dense and coarse structure with a relatively short growth cycle. To effectively disrupt this growth, treatments are spaced around four to six weeks apart. The frequency ensures that all follicles in the treated area are consistently targeted at their peak growth phase, particularly since underarm hair can be hormonally sensitive, potentially causing regrowth patterns to fluctuate.


6 – 8 Weeks

Leg hair has a slower growth cycle and a more extended dormant period than other body areas. This means that laser treatments can be spaced out over a longer duration, usually six to eight weeks apart. The longer interval allows for more follicles to emerge from dormancy and enter the active growth phase, which is when the laser is most effective. Also, since leg hair tends to be less hormonally influenced than other areas, session intervals are less likely to require frequent adjustments.

Back and Chest

8 – 10 Weeks

Back and chest hair tends to grow slowly but is typically thick and can be dense. Because of this, sessions are spaced eight to ten weeks apart to capture more hair in the active growth phase. The back may also have varying hair densities across different areas (e.g., upper back vs. lower back), potentially requiring more sessions. Hormonal influences can lead to changes in regrowth rates, so adjustments to the interval may be necessary to maintain consistent and optimal results.

How Many Sessions Do You Need for Laser Hair Removal?

On average, six to eight sessions are generally required for significant results, though maintenance treatments may be needed to handle any regrowth over time.

The number of laser treatment sessions required for effective laser hair removal varies based on factors like hair colour, thickness, skin type, body area, hormonal influences, and prior hair removal methods. 

Darker and thicker hair responds more effectively due to higher melanin levels, while lighter hair may need additional treatments. Individuals with lighter skin and darker hair often achieve quicker results due to the contrast, whereas those with darker skin may require specialized lasers.

Different body areas have varying hair densities and growth cycles, influencing session frequency; areas like the bikini and underarms may require fewer sessions compared to the legs or back. Hormonal changes, such as pregnancy or menopause, can affect regrowth, potentially increasing the number of sessions needed. 

Those who have previously relied on waxing or plucking might also need additional treatments. On average, six to eight sessions are generally required for significant results, though maintenance treatments may be needed to handle any regrowth over time.

What Happens if I Wait Too Long Between Laser Hair Removal Sessions?

Waiting too long between hair removal sessions can hinder the effectiveness of the treatment and lead to suboptimal results. If sessions are spaced too far apart, many hairs may miss the optimal window for treatment by reverting to a dormant state, requiring additional sessions to catch these hairs as they re-enter the growth phase. This can potentially lead to uneven results. 

On the flip side, scheduling sessions too closely can target hair that hasn’t yet entered the active growth phase, rendering the treatment less effective. Also, treating the same area too frequently increases the risk of side effects such as skin irritation, redness, and even burns or pigmentation changes, as the skin may not have sufficiently healed from the previous session. 

Adhering to the recommended session intervals maximizes both the efficacy and safety of the whole treatment plan, ensuring that each session contributes to the desired outcome.

Is Laser Hair Removal Worth It?

Laser hair removal is a significant investment in both time and money, but many find the long-term benefits worthwhile. Although the upfront costs can be high, those who achieve significant hair reduction save on ongoing expenses for waxing, shaving, and depilatory products. 

Successful treatments can also greatly reduce the time spent grooming, minimizing the hassle of daily shaving or regular salon appointments. Beyond cost and time savings, the laser hair removal process improves comfort by lessening irritation and ingrown hairs, particularly in sensitive areas like the bikini line.

A successful series of sessions can also boost your confidence, making you feel more comfortable in swimwear or during warm-weather months. However, it’s important to recognize that results vary, with some needing maintenance sessions to manage regrowth and others experiencing varying degrees of success due to individual differences in hair type, skin tone, and hormonal influences. 

Is Laser Hair Removal Right for You?

In the past, only people with dark hair and light skin could safely have laser hair removal. Today, advancements in laser hair removal mean that patients who have light-coloured hair and light skin and patients who have dark skin can also benefit from these treatments. However, there are some things to keep in mind.

Certain medical conditions or medications that increase photosensitivity can impact whether you should consider laser hair removal. That makes it important to consult with a healthcare provider first. Understanding that laser hair removal aims for significant hair reduction rather than total removal is key to setting realistic expectations.

Additionally, successful results require a commitment to the recommended treatment schedule and periodic maintenance sessions. The procedure is not entirely painless but is usually tolerable, with numbing creams or cooling systems helping minimize discomfort. 

Finally, hormonal conditions can affect the treatment’s long-term efficacy, so it’s essential to weigh these factors before starting a series of sessions. Your technician will discuss all these factors when planning your laser hair removal sessions.
