How Often Should Laser Hair Removal Be Performed?
Laser hair removal should be performed every 4-5 weeks, depending on the treatment area and individual factors. Regularity is crucial because the laser targets hair in the active growth phase (anagen). Maintaining the recommended intervals ensures the most effective removal of hair follicles and leads to long-lasting results.
Why Is Regularity Important?
Hair grows in three cycles:
1️⃣ Anagen – the active growth phase, during which the laser effectively destroys hair follicles,
2️⃣ Catagen – the transitional phase, when hair stops growing and is less responsive to the laser,
3️⃣ Telogen – the resting phase, after which hair falls out, and a new growth cycle begins.
Since not all hairs are in the anagen phase simultaneously, a series of treatments at regular intervals is required to target as many follicles as possible effectively.
How Many Sessions Are Needed for Permanent Results?
✅ On average, 6 to 8 sessions are recommended, but the number can vary based on:
✔️ Hair color and thickness – darker and thicker hairs respond better to laser treatment,
✔️ Treatment area – different body parts have varying numbers of hair follicles; for example, legs may require fewer sessions than the face,
✔️ Hormonal balance – hormonal fluctuations (e.g., high androgen levels) can lead to increased hair growth, extending the treatment duration,
✔️ Individual response – some people may achieve desired results in 4-5 sessions, while others may need up to 10.
Can the Treatment Intervals Be Shortened or Extended?
❌ Shortening the intervals is not recommended, as the laser is only effective on hairs in the anagen phase. Performing treatments too frequently may not produce the desired results.
❌ Extending the intervals beyond the recommended time frame is also not advisable, as hairs that could have been treated effectively may transition to the next growth phase, delaying the overall process.
How to Maintain Results After Completing the Treatment Series?
🔹 After completing the full series, maintenance sessions are recommended every 6-12 months to target any remaining hairs that may grow due to hormonal changes or natural skin regeneration.
🔹 Avoid plucking or waxing hair between sessions, as removing the follicle can reduce the effectiveness of future treatments. If hair removal is necessary, shaving is the best option.
🔹 Protect treated areas from sun exposure by using SPF 50 sunscreen, as the skin becomes more sensitive to UV radiation after laser treatment.
In our opinion
🔹 Laser hair removal should be performed every 4-5 weeks to target hair in the active growth phase effectively.
🔹 A full treatment course usually consists of 6-8 sessions, but individual factors may influence the number of required treatments.
🔹 Regularity is key – altering the recommended intervals can reduce the effectiveness of the procedure.
🔹 After completing the sessions, maintenance treatments every 6-12 months help ensure long-lasting smooth skin.
