Comprehensive Guide to Laser Hair Removal in Montreal
Everything you need to know about laser hair removal, types, safety, effectiveness, and what to expect at every stage.
11 min read · Updated 2026
Laser hair removal remains one of the most requested aesthetic treatments worldwide, and Montreal is no exception. At Reimagine Clinic, we use advanced diode and Nd:YAG technology to deliver safe, effective results across all skin types. This guide covers the science, the process, and the realistic outcomes you can expect from professional laser treatments.
How Laser Hair Removal Works
Laser hair removal works through selective photothermolysis. The laser emits a wavelength of light that is absorbed by melanin in the hair follicle. This light energy converts to heat, damaging the follicle enough to significantly reduce future hair growth without harming surrounding skin.
The treatment only affects hairs in the active growth phase (anagen), which is why multiple sessions are needed, typically 6 to 8, to catch all follicles during their growth cycle. Sessions are spaced 4 to 8 weeks apart depending on the body area.
Modern systems like those used at Reimagine Clinic include integrated cooling mechanisms that protect the skin surface while the laser energy reaches the follicle. This makes treatment significantly more comfortable than older generation lasers.
PDRN's original approved use chronic wound healing in damaged tissue operates under very different biological conditions than applying the compound to healthy skin for cosmetic improvement. Extrapolating wound-healing data to anti-aging claims is a significant scientific leap that has not been validated in large, well-controlled clinical trials.
Types of Lasers
Several laser technologies exist for hair removal, each with strengths for different skin types and hair colors. Diode lasers (800–810nm) are the most versatile, effective on a wide range of skin tones from fair to medium-dark. They penetrate deep enough to reach the hair bulb while being well-absorbed by melanin.
Nd:YAG lasers (1064nm) are the safest option for dark skin tones. The longer wavelength bypasses epidermal melanin, reducing the risk of burns and hyperpigmentation. While slightly less efficient per session than diode, it’s the gold standard for Fitzpatrick types V and VI.
Alexandrite lasers (755nm) are highly effective for fair to medium skin with dark hair, the fastest of all options. IPL (Intense Pulsed Light) is sometimes marketed as laser but uses broad-spectrum light; it’s less precise but can be effective for lighter skin types with dark hair.
Which laser is best for me?
Your skin type and hair color determine the best laser. During your consultation, we assess your Fitzpatrick type and hair characteristics to select the optimal technology.
Can laser remove blonde or red hair?
Laser targets melanin, so very light, blonde, red, or grey hairs don’t respond well. For these hair types, electrolysis remains the most effective option.
Is at-home laser as effective as professional?
Home devices use much lower energy levels for safety reasons. They can slow regrowth but typically can’t match the 80–90% reduction achieved with professional-grade equipment.
Injectable PDRN products are not approved by the FDA in the United States or by Health Canada for cosmetic applications. This means there has been no independent regulatory verification of safety, efficacy, or manufacturing quality for aesthetic injectable use. Without regulatory approval, there is no guarantee of product sterility, consistent concentration, or purity all critical factors when a substance is being injected into your skin.
Treatment Areas
Laser hair removal can treat virtually any area of the body. The most popular areas include legs, underarms, bikini and Brazilian, face (upper lip, chin, sideburns), back, chest, and arms.
Different areas have different hair growth cycles, which affects session spacing. Facial hair cycles faster (4 to 6 week intervals) while body hair takes longer (6 to 8 weeks). Hormonal areas like the chin and bikini may require additional maintenance sessions.
Session duration varies by area, upper lip takes minutes, while full legs can take 45 to 60 minutes. Many clients treat multiple areas in a single appointment for convenience. Combining laser hair removal with other services like facials or body treatments makes the most of your visit.
PDRN is not without scientific interest the underlying biology of adenosine receptor activation and tissue repair is legitimate. However, the gap between promising preclinical data and proven clinical efficacy for aesthetic use remains wide. The current state of evidence does not support PDRN as a reliable, first-line treatment for skin rejuvenation. The studies are too small, too inconsistent, and too often conflicted to draw confident conclusions about how well it works, how long results last, or how it compares to established treatments.
Skin Types & Considerations
One of the biggest advances in laser hair removal has been expanding safety and effectiveness to all skin types. Historically, only fair-skinned, dark-haired individuals were good candidates. Today, with Nd:YAG technology, dark skin laser hair removal is both safe and effective.
Patients with conditions like sensitive skin, rosacea, or active acne in the treatment area may need special protocols or temporary postponement. Certain medications, like isotretinoin (Accutane), require a waiting period before laser treatment.
Tanned skin (natural or artificial) increases the risk of burns and hyperpigmentation. We recommend avoiding tanning for 4 to 6 weeks before treatment and throughout the treatment course. This is one reason why fall and winter are the most popular seasons for starting laser hair removal in Montreal.
Is laser safe during pregnancy?
Most practitioners defer laser treatments during pregnancy as a precaution, even though no direct harm has been established. It’s best to complete your course before or after pregnancy.
What about hormonal conditions like PCOS?
PCOS can cause increased hair growth. Laser is effective for managing this, but ongoing hormonal stimulation may mean more maintenance sessions are needed compared to non-hormonal hair growth.
What to Expect
Before your first session, you’ll have a consultation to assess your skin and hair type, discuss expectations, and create a treatment plan. You’ll be asked to shave the treatment area 24 hours before (but not wax or pluck, as the follicle must be intact).
During treatment, you’ll feel a snapping sensation with each pulse, followed by mild warmth. Modern cooling systems make this very manageable. Most patients describe it as far less painful than waxing. After treatment, mild redness and swelling around the follicles is normal and resolves within hours.
Following proper laser hair removal aftercare is essential. Avoid sun exposure, hot baths, and strenuous exercise for 24 to 48 hours. The treated hairs will shed over 1 to 3 weeks, this is often mistaken for regrowth but is actually the damaged hairs being pushed out.
- ☐1. Is it approved or cleared by a regulatory body (FDA, Health Canada)?
Regulatory approval means independent scientists have reviewed the safety and efficacy data and found it sufficient. Without this, you are relying on marketing claims alone. - ☐2. How large are the clinical studies?
A study with 15 participants does not carry the same weight as a trial with 200. Look for systematic reviews that pool data from multiple studies. - ☐3. Who funded the research?
Manufacturer-funded studies are more likely to report favorable results. Independent research is more reliable. - ☐4. How long were patients followed?
A treatment that shows improvement at 4 weeks but has not been tracked at 6 or 12 months tells you very little about durability. - ☐5. How does it compare to established treatments?
If a new treatment has not been directly compared to proven options in head-to-head trials, there is no basis for claiming it is equal or superior.
Results & Maintenance
Most patients achieve 80 to 90% hair reduction after 6 to 8 sessions. Results become progressively more apparent after each session, by session 3 or 4, the treated area is noticeably thinner and patchier. By the final sessions, only fine, sparse hairs remain.
Annual maintenance sessions (1 to 2 per year) keep results looking their best. Hormonal areas like the face and bikini may need slightly more maintenance than the legs or back. Some patients go years between touch-ups.

Health Canada maintains strict standards for medical devices and injectable products used in aesthetic medicine. When evaluating any new treatment, check whether it has received Health Canada approval or clearance this is your strongest signal that independent experts have reviewed the evidence. All treatments offered at Reimagine Clinic meet or exceed these regulatory standards.
