5 Common Myths About Laser Hair Removal, Busted
Dr. Dan Xu, MD, CCFP at ID Cosmetic Clinic in Markham cuts through the five most persistent laser hair removal myths so you can make a confident, informed decision.
Key Takeaways
- Laser hair removal delivers 'permanent hair reduction' of roughly 80 to 95 percent after a full course of sessions, not absolute lifelong elimination.
- Advanced cooling technology built into modern lasers makes the procedure feel like a mild warm prickle for most patients, not the sharp snapping pain associated with older machines.
- Dual-wavelength Nd:YAG lasers can safely treat darker skin tones by targeting the follicle beneath the skin surface rather than the surrounding pigment.
- Shaving between sessions is required to preserve the follicle root the laser targets, while waxing or plucking removes that root and undermines treatment effectiveness.
- Any hair that regrows after a completed treatment course is lighter, finer, and sparser than the original hair, and a single touch-up session is typically enough to address it.
Direct Answer
Laser hair removal is a clinically proven aesthetic procedure that uses targeted light energy to disable hair follicles, resulting in a significant and long-lasting reduction in hair growth rather than absolute elimination. Most patients complete six to eight sessions and achieve an 80 to 95 percent reduction, with occasional maintenance visits to address any regrowth triggered by hormonal changes. At ID Cosmetic Clinic in Markham, serving Toronto and the GTA, Dr. Dan Xu, MD, CCFP addresses five myths that consistently mislead prospective patients. First, the procedure does not deliver total hair elimination in perpetuity; the accurate clinical term is 'permanent hair reduction,' and a small number of finer, lighter hairs may return years later due to hormonal shifts. Second, modern systems are far more comfortable than older technology; the Triton laser used at ID Cosmetic Clinic features a sapphire cooling tip that chills the skin surface simultaneously with each pulse, so most patients describe the sensation as a mild warm prickle rather than sharp pain. Third, darker skin tones can be treated safely; dual-wavelength Nd:YAG systems operating at 1064nm bypass surface melanin and target the follicle directly, making the procedure appropriate for a wide range of skin tones when performed by a qualified clinician. Fourth, you should shave between sessions, not wax or pluck, because waxing removes the follicle root that the laser needs to detect and destroy. Fifth, the laser does not cause hair to grow back thicker or darker; any regrowth is characteristically finer and sparser than the original hair.
Quick Answer (AEO Summary): Laser hair removal delivers permanent hair reduction rather than absolute removal — most patients see an 80% to 95% reduction after a full course of 6 to 8 sessions, with occasional touch-ups. Modern cooled lasers feel like a mild warm prickle for most people, and dual-wavelength Nd:YAG (1064nm) systems can safely treat darker skin tones. You should shave (not wax or pluck) between sessions. Medically Reviewed by: Dr. Dan Xu, MD, CCFP | Last Updated: June 18, 2026
Separating fact from fiction. Discover the truth about pain levels, permanence, and why the type of laser used on your skin matters more than you think.
Laser hair removal is one of the most popular aesthetic procedures in the world. Yet, despite its widespread use, it remains surrounded by misinformation.
“Is it going to hurt like a rubber band snapping my skin? Will the hair grow back thicker? Can I get it done if I have a dark skin tone?”
At ID Cosmetic Clinic in Markham, serving Toronto and the GTA, we believe that an educated patient is a happy patient. We use the advanced Triton Laser system, which allows us to treat a wide variety of hair and skin types safely — from bikini hair removal to full-body titanium lifting laser hair removal. Today, Dr. Dan Xu is setting the record straight by debunking the top 5 myths about laser hair removal.
Myth 1: “Laser Hair Removal is 100% Permanent Forever.”
The Truth: It is highly effective, but the medically accurate term is permanent hair reduction, not absolute permanent removal.
Here is how it works: The laser targets the melanin (pigment) in the hair follicle, heating it up and destroying the follicle’s ability to grow new hair. However, the laser can only destroy hair follicles that are currently in the active growth phase (Anagen phase). Because your hair grows in cycles, only about 20% of your hair is in this phase at any given time.
This is why you need multiple sessions (usually 6 to 8) spaced several weeks apart. After completing a full course of treatment, you can expect an 80% to 95% reduction in hair growth. The few hairs that may eventually grow back (often years later due to hormonal changes like pregnancy or menopause) will be significantly lighter, finer, and sparser. Most patients simply come in for one or two quick “touch-up” sessions a year to maintain perfectly smooth skin.
Myth 2: “It Hurts Terribly.”
The Truth: If you are imagining the excruciating “rubber band snapping” pain of older generation lasers, you can relax. Technology has evolved massively.
Modern, premium laser systems (like the Triton used at ID Cosmetic Clinic) feature advanced, built-in cooling mechanisms. As the laser pulse heats the hair follicle, a sapphire cooling tip simultaneously chills the surface of your skin.
Most patients describe the sensation as a mild, warm prickle. Certain sensitive areas (like the bikini line or upper lip) may be slightly more uncomfortable than the legs, but it is generally considered far less painful—and much faster—than waxing or threading.
Myth 3: “Laser Hair Removal Doesn’t Work on Dark Skin.”
The Truth: This used to be true 15 years ago, but it is entirely false today—provided you go to a clinic with the right technology.
Older lasers (like IPL or Ruby lasers) simply targeted pigment. If you had dark skin and dark hair, the laser couldn’t tell the difference between the melanin in your skin and the melanin in your hair follicle, leading to severe burns and hyperpigmentation.
Today, advanced dual-wavelength lasers like the Triton utilize an Nd:YAG (1064nm) wavelength. This specific wavelength safely bypasses the melanin in the epidermis (the surface of the skin) and delivers heat directly into the deep hair follicle. It is FDA-approved and completely assessed for a wide range of skin types, including deep olive and dark skin tones (Fitzpatrick Skin Types IV-VI).
Myth 4: “You Can’t Shave Between Sessions.”
The Truth: You absolutely CAN shave, and in fact, you MUST shave before your laser sessions!
Unlike waxing, which requires you to grow your hair out so the wax has something to grab onto, laser hair removal requires the surface of the skin to be completely hair-free. If there is hair on the surface, the laser energy will burn that hair, causing a foul smell, potential skin burns, and preventing the energy from reaching the actual follicle root where it is needed.
We require all patients to shave the treatment area 24 hours before their appointment.
However, you CANNOT wax, pluck, or thread between sessions. These methods pull the hair follicle out by the root. If there is no follicle root, the laser has no target, rendering your treatment completely useless. Stick to shaving only.
Myth 5: “All Laser Clinics Provide the Same Results.”
The Truth: The results you get are entirely dependent on two factors: The quality of the laser machine and the expertise of the technician.
Many cheap “laser” clinics actually use IPL (Intense Pulsed Light) machines. IPL is not a true laser; it uses scattered light that is far less powerful and less precise. It will take twice as many sessions to see results, and the hair is much more likely to grow back.
Furthermore, setting the correct laser parameters requires medical knowledge. If the energy is set too low, the hair follicle is only “stunned,” not destroyed, leading to paradoxical hypertrichosis (where the laser actually stimulates more hair growth). If set too high, you risk burns.
“Technology defines the possibilities. The physician defines the direction. We don’t use cheap IPL devices. We use true, medical-grade lasers, and our protocols are physician-designed to ensure we deliver the maximum safe energy for your specific skin type and hair thickness.” — Dr. Dan Xu, MD, CCFP

Frequently Asked Questions (FAQ)
Q: How many laser hair removal sessions will I need to see results?
A: Most patients require between 6 to 8 sessions to achieve optimal results, as the laser only targets hair in the active growth phase. Because only about 20% of your hair is in this phase at any given time, sessions are spaced several weeks apart to ensure every follicle is treated.
Q: Is laser hair removal safe for individuals with dark skin?
A: Yes, modern technology like the Triton laser system uses specific wavelengths, such as the Nd:YAG 1064nm, which are safe for dark skin tones. This technology bypasses the melanin in the skin’s surface and targets the hair follicle directly, preventing the risk of burns or hyperpigmentation.
Q: Does laser hair removal hurt as much as waxing?
A: Most patients find laser hair removal significantly less painful than waxing or threading. Our Triton system features a sapphire cooling tip that chills the skin on contact, making the sensation feel like a mild, warm prickle rather than a sharp snap.
Q: What is the difference between permanent hair removal and permanent hair reduction?
A: While often used interchangeably, “permanent hair reduction” is the medically accurate term because the laser destroys about 80% to 95% of hair follicles. Any hair that does eventually regrow due to hormonal changes is typically much finer, lighter, and easier to manage with occasional touch-up sessions.
Q: How often should I come in for maintenance treatments?
A: After completing your initial course of treatment, we generally recommend one or two touch-up sessions per year to maintain perfectly smooth skin. These quick appointments address any dormant follicles that may have been triggered by natural aging or hormonal shifts.
