What Is Laser Hair Removal & How Does It Work?
Laser hair removal works through a process called selective photothermolysis. This involves targeting melanin (the pigment in your hair) with concentrated laser light. That light heats and damages the hair follicle, reducing or stopping future hair growth while preserving surrounding skin tissue.
Different lasers are used for different skin tones and hair types, including:
- Diode lasers (commonly 755/810 nm)
- Alexandrite lasers (for lighter skin tones)
- Nd:YAG lasers (1064 nm – ideal for darker skin)
Because hair grows in cycles, multiple sessions are needed to treat hair during its active growth phase (anagen), when it’s most susceptible to laser energy.
What “Permanent Hair Removal” Really Means
One of the biggest misconceptions in this industry is the term “permanent hair removal.”
The truth is, even with the most advanced equipment, no laser treatment can guarantee total and permanent hair removal for every individual. Instead, the term most accurately used is “permanent hair reduction.”
According to the American Academy of Dermatology, most patients remain hair-free for months or even years. When hair does regrow, it tends to be lighter, finer, and far less dense, requiring minimal touch-ups to maintain results.
The Mayo Clinic also states that while laser hair removal can offer long-lasting results, it “does not guarantee permanent hair removal” and maintenance may be required over time. (Source)
How Long Does Laser Hair Removal Last? (Face vs Body)
The longevity of results varies significantly depending on the area treated, laser type used, and your body’s unique response.
Here’s what the clinical data tells us:
- A study using an 810 nm diode laser showed ~70% hair reduction maintained at 1 year after just three sessions.
- Another study using an 800 nm long-pulsed diode showed 54% clearance at 6 months, with 42% maintained at 15 months, though remaining hair was lighter and thinner. (PubMed Source)
- A 2022 review across multiple systems found Nd:YAG lasers offered 30–73% long-term reduction, while Alexandrite lasers averaged 35%+. (Full study)
- A rotational protocol using mixed wavelengths achieved ~75% reduction at six months, showing the value of blended laser systems.
That said, facial hair—especially on the chin, lip, or jawline—is often more hormonally influenced and more likely to return faster than hair on areas like the legs or underarms.
Some clients report no regrowth for years, while others may see some return within months, especially if hormonal conditions like PCOS are present. (Healthline article)
Factors That Affect How Long Results Last
Several key factors influence the duration of laser hair removal results:
1. Hair Color & Skin Tone
Laser hair removal works best on people with light skin and dark hair, as the laser targets melanin in the follicle. The higher the contrast, the more effective the treatment. While newer devices like Nd:YAG lasers have made treatment safer for darker skin tones, results may vary.
2. Hormonal Influences
Hormones play a major role, especially for facial hair. Conditions such as PCOS, thyroid imbalances, or even natural fluctuations can reactivate dormant follicles, triggering regrowth—even after a full treatment series.
3. Consistency of Treatments
The best results are achieved when clients follow the treatment plan closely. Skipping or delaying sessions can allow hair to cycle out of the targetable growth phase, reducing long-term effectiveness.
4. Laser Technology
Not all devices are created equal. Medical-grade lasers with integrated cooling systems and calibrated wavelengths—like those used at Perizia Aesthetics—deliver better results, faster, and with lower risk of side effects.
5. Number of Sessions
Clients who complete a full series of treatments (typically 6–8) and follow up with regular maintenance achieve longer-lasting smoothness compared to those who stop prematurely.
How Many Sessions Will You Need?
Laser hair removal isn’t instant—and it shouldn’t be. To be safe and effective, treatments are spaced out over time to align with the hair’s natural growth cycle.
Most clients need:
- 6 to 8 sessions, spaced 4 to 6 weeks apart
- Touch-ups every 6 to 12 months for long-term maintenance
Facial areas may require more frequent sessions than body areas, depending on hair density and hormonal activity.
While treatment plans are highly personalized, committing to the full schedule is key to achieving results that last.

Maintenance Matters: Why Touch-Ups Are Key
Even after completing the recommended number of sessions, laser hair removal isn’t a “set-it-and-forget-it” treatment—especially on hormonally sensitive areas like the face.
Maintenance treatments help reinforce your initial results and ensure that any dormant follicles activated by hormonal changes are addressed. Many clients schedule touch-ups every 6 to 12 months, though some may go longer without needing one.
The American Academy of Dermatology explains that regrowth is usually finer and less noticeable, and consistent maintenance helps reduce the need for more intensive treatments later.
It’s also worth noting that skipping touch-ups can allow hair to grow back stronger, especially if hormonal conditions are present. This is why personalized maintenance plans, based on your hair growth and body chemistry, are essential for sustaining long-term results.

Ideal candidates typically:
- Have dark, coarse hair
- Are in good health

FAQs: Common Questions About Laser Hair Removal Longevity
Does it last forever?
Not exactly. Laser hair removal offers permanent hair reduction, not complete elimination. Most clients experience months or years of smooth skin, with only light regrowth afterward.
Will I ever have to shave again?
Possibly, but not often. Any regrowth is typically finer and lighter, making shaving less frequent and far easier.
Can I skip maintenance treatments?
You can, but it’s not advised—especially for facial hair or hormonally active areas. Skipping touch-ups may lead to increased regrowth over time.
Is it safe for hormonal hair growth (e.g., PCOS)?
Yes. Laser treatment is an effective solution for hormonal facial hair, though you may need more frequent sessions to manage regrowth. Always consult with a professional to tailor your plan.
What if I stop treatments early?
Stopping too soon may reduce your overall results. Hair may return faster, and in greater density, if the full treatment cycle isn’t completed.
