Tired of shaving every other day or booking endless waxing appointments that leave your skin irritated and your wallet lighter? You’re not alone.
Searching for smooth, hair-free skin often feels like a frustrating cycle. If you’ve considered laser hair removal, you’ve probably wondered why there are so many types and which one actually works for you.
Here’s the deal: not all laser hair removal treatments are created equal. What works beautifully for one person might lead to breakouts, burns, or zero results for another. That’s where understanding the different types of laser hair removal becomes your secret weapon.
In this guide, we’ll help you choose the right type of laser based on your skin tone, hair type, and goals. Smooth skin starts with smart choices. Let’s get into it.
What is Laser Hair Removal and Why Does the Type of Laser Matter
Laser hair removal uses targeted light energy to destroy hair follicles. The laser’s wavelength is absorbed by the pigment (melanin) in the hair, generating heat that stops future growth. But here’s the key: different lasers penetrate the skin at different depths and intensities.
That’s why one type of laser might work wonders on fair skin with dark hair, while another is designed to be safe for deeper skin tones.
According to a study published in the Journal of Clinical and Aesthetic Dermatology, the choice of laser directly affects both the effectiveness and safety of treatment, especially for individuals with higher Fitzpatrick skin types (darker skin tones).
Breaking Down the Types of Laser Hair Removal (And Which One’s Right for You)
Let’s go through the most common laser hair removal types used today. Each has a specific wavelength, level of skin penetration, and compatibility range.
1. Alexandrite Laser (755 nm)
Best for: Light to olive skin (Fitzpatrick I–III)
Great for: Arms, legs, chest, underarms
Speed: Very fast treatment time
The Alexandrite laser is one of the most widely used technologies, known for its ability to treat large areas quickly. It targets melanin effectively, which makes it ideal for fair skin with darker hair. However, it’s not recommended for deeper skin tones, as it can cause pigmentation changes.
2. Diode Laser (800–810 nm)
Best for: Light to medium-dark skin (Fitzpatrick I–IV)
Great for: Coarse or stubborn hair (e.g., back, bikini line, chest)
Comfort: Painless with cooling systems
Diode lasers offer deep skin penetration and are excellent for dense or coarse hair. They’re a top choice for men’s hair removal. With modern cooling technology, they’re also one of the most comfortable options out there.
They tend to require fewer sessions than IPL and are safer on slightly darker skin tones, although care must still be taken with higher Fitzpatrick types.
3. Nd: YAG Laser (1064 nm)
Best for: Dark to very dark skin (Fitzpatrick IV–VI)
Great for: All body areas, including sensitive skin
Safety: Minimal risk of pigmentation issues
The Nd: YAG laser is your go-to if you have deeply pigmented skin. Its long wavelength allows it to bypass the skin’s surface pigment and target the follicle directly, reducing the risk of burns or discolouration.
4. Ruby Laser (694 nm)
Best for: Very light skin (Fitzpatrick I–II)
Great for: Fine hair, facial areas
Drawback: Slower treatment speed
The Ruby laser was the first laser developed for hair removal. It’s gentle and works well on light, thin hairs, but it’s less commonly used now because it can’t safely treat darker skin and takes longer per session.
5. IPL (Intense Pulsed Light) – Not Technically a Laser
Best for: Light skin with dark hair
Great for: Larger areas (legs, arms)
Budget-Friendly: More affordable than true lasers
IPL uses a broad spectrum of light and is not as focused as a laser. That makes it more flexible but less powerful. It often requires more sessions and isn’t safe for darker skin tones. However, it’s commonly used in cosmetic clinics due to its low cost and added skin rejuvenation benefits.
How to Choose the Right Laser for Your Skin Tone and Hair Type
Laser hair removal works best when it’s based on a clear understanding of your skin and hair type. To make the right treatment decisions, dermatologists often refer to the Fitzpatrick Skin Type Scale, a system that helps identify how your skin reacts to light and laser exposure. This scale plays a key role in selecting the safest and most effective laser technology for your individual needs.
Here’s a quick overview:
- Type I: Very fair, always burns
- Type II: Fair, burns easily
- Type III: Medium, sometimes burns
- Type IV: Olive skin, rarely burns
- Type V: Brown skin, tans easily
- Type VI: Deeply pigmented skin, never burns
If you’re Type I–III, Alexandrite or Diode is typically ideal.
If you’re Type IV–VI, you’ll need the safer, deeper-reaching Nd: YAG.
Have light hair? Diode may still work, but you’ll need an expert approach.
Matching the Right Laser to the Right Body Area
Not all lasers perform equally on every part of the body. Here’s a quick guide:
Medium areas (most common treatment zones):
- Underarms
- Half legs
- Bikini line
- Forearms
Diode and Alexandrite lasers usually perform best on these medium areas, which offer the perfect balance of speed, precision and comfort.
Benefits of Using the Right Type of Laser Hair Removal
Choosing the right laser means:
- Faster sessions and quicker results
- Fewer total treatments (typically 6–8 for noticeable reduction)
- Minimised side effects (less redness, no burns)
- Long-term smoothness with finer regrowth
Laser hair removal isn’t just about looking good. It’s about saving time, reducing skin irritation, and feeling confident in your own skin, every single day.

Debunking Myths About Laser Hair Removal
Let’s clear a few things up:
- “It’s painful.” Not true. With modern cooling systems, most people compare it to a quick snap or warm pulse.
- “It doesn’t work on dark skin.” That’s outdated. Nd: YAG lasers are made for deeper skin tones.
- “It’s only for women.” False again—laser hair removal is one of the fastest-growing services for men in Canada.
