This article explains how many laser hair removal sessions you need, how long you should wait in between laser hair removal sessions, how long hair removal lasts and how long laser hair removal takes.
How many laser hair removal sessions are needed?
The number of laser hair removal sessions needed varies depending on several factors including an individual’s hair type, hair color, skin tone, and the treatment area, as well as the specific laser technology used. Generally, patients require an average of 5 to 8 sessions to achieve optimal results. However, this is a general guideline, and individual results may vary.
A 2008 study published in the Journal of Cosmetic and Laser Therapy shows repetitive treatments are more effective than single treatments. However more side effects occur with a higher number of treatments:
The authors found a positive correlation between hair reduction and number of treatments. The success rates were: 25% for patients receiving four or fewer treatments, 76% for five treatments, 58% for six treatments, and 15% for seven treatments. The lower rate of success in the six and seven treatments’ groups is attributed to a higher incidence of side effects such as hyper and hypo-pigmentation, blister, and folliculitis.
The reason multiple sessions are necessary is because hair growth occurs in different cycles or phases: anagen (active growth phase), catagen (transitional phase), and telogen (resting phase). Laser hair removal is most effective during the anagen phase when the hair is actively growing and contains more melanin, which absorbs the laser energy and results in follicle damage that inhibits future hair growth.
Due to the fact that hair grows in cycles and not all hair follicles are in the anagen phase simultaneously, multiple sessions are required to target hairs in their growth phase. These sessions are usually spaced 4 to 6 weeks apart to ensure the next set of hairs in the anagen phase can be targeted.
Additionally, factors such as hormonal changes/imbalance, medications, and genetic predisposition can influence the number of sessions required to achieve the desired results. Laser hair removal tends to be more effective on darker hair types with more melanin content and may require additional sessions for lighter hair types such as blonde, gray, or red hair.
How many laser hair removal sessions are needed for Brazilian?
On average, clients typically need 6 to 8 sessions spaced 4 to 6 weeks apart to achieve optimal results with Brazilian treatments. However, it is important to understand that individual results may vary. The number of laser hair removal sessions required for a Brazilian treatment varies depending on several factors, including hair color, skin type, hair density, and the specific laser technology utilized.
How many laser hair removal sessions are needed for bikini?
On average, patients typically require 5 to 10 sessions for optimal results with treatments on the bikini area. However, this is a general estimate, and the precise number of sessions may differ among individuals.
How many laser hair removal sessions are needed for legs?
On average, most individuals require approximately 3 to 6 sessions in order to achieve optimal results with treatments on the legs. This estimation takes into account the different stages of the hair growth cycle, which are anagen (active growth), catagen (transitional), and telogen (resting). The number of laser hair removal sessions needed for legs varies depending on several factors such as the individual’s hair growth cycle, hair color, skin type, and the specific laser technology used.
How many laser hair removal sessions are needed for armpits?
On average, most individuals require 6 to 8 sessions to achieve optimal results and long-lasting hair reduction. The number of laser hair removal sessions required for the armpit area can vary from individual to individual, as it depends on factors such as hair color, skin type, genetics, and hormonal levels.
How many laser hair removal sessions are needed for face and neck?
On average, a patient typically requires 6 to 8 sessions, spaced around 4 to 6 weeks apart, to achieve the best results with treatments on the face and neck. However, this number may increase or decrease based on the individual’s unique characteristics. The number of laser hair removal sessions required for the face and neck varies depending on several factors, such as hair color, thickness, skin type, hair growth cycle, and hormonal fluctuations.
How long should I wait between laser hair removal sessions?
You should generally wait 4-6 weeks between laser hair removal sessions, for most treatment areas but you can wait up to 10 to 12 weeks between sessions for areas such as the back and legs, based on the individual’s growth cycle.
Waiting too long between laser hair removal sessions can reduce the effectiveness of the treatment. Laser hair removal sessions are scheduled a few weeks apart to coincide with the hair growth cycle. If you wait too long, new hair can grow, and the laser won’t be as effective in treating it.
It’s crucial to follow the recommended ideal wait times between sessions to achieve the best and long-lasting results.
Is 10 weeks too long between laser hair removal sessions?
No, 10 weeks is not necessarily too long between laser hair removal sessions. The interval period between laser hair removal sessions, usually ranging from 4 to 6 weeks, primarily depends on the individual’s hair growth cycle and treatment area. For example, it is entirely possible that while treating the leg area, based on the individual’s growth cycle it is recommended to wait up to 10-12 weeks between sessions.
Hormonal changes, genetics, and body area being treated could influence the length of the interval period. For instance, facial hair tends to grow faster than leg hair, and therefore may require more frequent sessions. Similarly, individuals with polycystic ovary syndrome could experience faster hair growth, necessitating tailored treatment plans.
Is 8 weeks too long between laser hair removal sessions?
No, waiting 8 weeks between laser hair removal sessions is not necessarily too long, depending on the treatment area and person. However, laser treatment works best when hairs are in the early anagen stage of growth, which is why the general rule is to wait 4 to 6 weeks between sessions. It is best to consult with a professional to determine the ideal waiting time between sessions for your particular situation.
Can I do laser hair removal every week?
No you should not do laser hair removal every week. The ideal time frame for laser hair removal sessions is typically 4-6 weeks. Scheduling treatments too close together can damage the skin and does not give the hair enough time to fall out naturally. Laser hair removal works by targeting hair in its growth stage, which is typically every 4-6 weeks. This ensures that the laser targets as many hair follicles as possible.
Additionally, spacing out appointments allows the skin time to heal and regenerate after each session.
What happens when you wait too long between laser hair removal sessions?
Waiting too long between sessions (for example 6 months) can reduce the effectiveness of the treatment and cause you to need more sessions overall. Typically, hair grows in cycles, so it’s important to catch the hair during its active growth phase.
Waiting too long between sessions of laser hair removal generally does not lead to skin damage or burns. Waiting too long between laser hair removal sessions also does not cause more pain during the treatment.
Can I wax in between laser hair removal sessions?
No you should not wax in between laser hair removal sessions. Waxing immediately after laser hair removal may potentially undo the laser progress, and it is not advisable. Waxing removes the hair from the root, which the laser targets during treatment. Waxing can cause hair to grow back thicker and darker, which may require further laser treatment. The laser targets the melanin in the hair follicle, so if the hair is pulled out before it falls out naturally, the laser won’t be able to target it. It is recommended to shave the hair instead in-between laser sessions.
How long does laser hair removal last?
Laser hair removal is a long-lasting method for hair reduction, with most individuals experiencing a 70-90% reduction in hair density. The permanence of laser hair removal varies from person to person and is influenced by factors such as hair color, skin type, hair growth cycle, hormonal imbalances, genetic factors, and the consistency of treatments. The duration of laser hair removal efficacy is dependent on individual factors and the consistency of follow-up treatments.
It is essential to consider that laser hair removal does not result in the complete cessation of hair growth, but rather a significant reduction in hair density and coarseness.
Following the initial treatment regimen, touch-up sessions may be required at varying intervals, typically 1-3 times a year, depending on an individual’s response to treatments and specific hair regrowth patterns.
What is the laser hair removal timeline?
The laser hair removal timeline can be divided into 4 stages, which include:
- Treatment sessions,
- Post-treatment care
- Long-term maintenance.
Once the initial 4-6 treatment sessions are completed, you may experience a significant reduction in hair growth. However, due to hormonal changes or individual factors for hair growth, some clients might require maintenance sessions once or twice a year to keep their results.
By following this laser hair removal timeline and adhering to the recommended treatment plan, individuals can achieve long-lasting, satisfactory results with minimized hair growth in the targeted areas.
What happens to stubble after laser hair removal?
After laser hair removal, the stubble undergoes a process termed as “Photothermolysis.” This is a selective process where controlled thermal damage is caused to the hair follicles, making them less likely to grow unwanted hair.
The treated stubble will eventually shed, as the heat from the laser has compromised the hair follicle, making it less functional. The shedding may take up to 2-3 weeks post-treatment, but it’s essential not to confuse this with hair growth. During this period, you may notice what appears to be hair regrowth; however, this is simply the shedding of the treated hair as it is being pushed out of the follicle by the body’s natural process. This phenomenon is known as the “Ejection Phase.”
How long does laser hair removal take?
The duration of a laser hair removal session depends on several factors, including the size of the treatment area, the density and type of hair, and the specific laser technology employed. Generally, laser hair removal sessions can take anywhere from a few minutes to an hour or more per session. A 2012 research paper published by Se Hwang Liew in the American Journal of Clinical Dermatology shows hair clearance of 30 to 50% is generally reported 6 months after the laser treatment.
Here’s a breakdown of the factors affecting treatment duration:
- Treatment area size: Smaller areas like the upper lip or underarms may take as little as 5-10 minutes, while larger areas, such as the back or full legs, can take up to an hour or more.
- Hair density: Higher hair density (the number of hair follicles per unit area) takes longer, as more hair follicles need to be targeted during the procedure. Likewise, lower density areas may require less time for each session.
- Hair type and thickness: Coarser and darker hair may require slightly longer treatment sessions, as these hair types absorb more laser energy and require more thorough targeting for effective treatment.
- Laser technology: The efficacy of laser hair removal is dependent on the specific laser device used. Systems like Nd:YAG, Alexandrite, and Diode utilize different wavelengths and pulse durations, which can influence the overall treatment time. Experienced practitioners will choose the best-suited laser for each patient’s skin type, hair type, and treatment goals.
- Treatment protocol: It typically takes multiple sessions (6-7 on average) spaced several weeks apart (4-6 weeks) to achieve optimal results. This spacing allows targeting hair follicles during their active growth phase (anagen phase) and reduces the possibility of damaging the surrounding tissue.
In conclusion, the time required for laser hair removal largely depends on the patient’s unique characteristics and the specific laser technology. While each session’s duration may vary, achieving optimal results will ultimately require a series of treatments performed by an experienced practitioner.
