Beard Hair Removal: Why More Sessions Alone Won't Cut It

"I had 8 sessions somewhere else, and I still have beard hair."

This is something I hear all the time in the consultation room.

The number of sessions may not be the real issue.

With men's beard hair removal, choosing the wrong wavelength means
no matter how many sessions you get, you may only see half the results.

💡 Check this before you read on

Q. If I just keep adding more sessions, won't the beard eventually disappear completely?

A. The truth is, if the wavelength isn't right, more sessions will only get you so far.
Beard hair is structurally different from hair on other parts of the body.

Q. Is there a specific reason men's beards are especially difficult to remove?

A. Yes, there is.
It comes down to the depth and thickness of beard follicles, which are different from other areas.
I'll walk you through the details below.

Q. Between 755nm and 1064nm, which wavelength should I go with?

A. It's not a matter of choosing one or the other—alternating between both wavelengths is the right approach.
The strategy varies depending on skin tone and follicle depth.
I've broken it down by type below.

"For men's beards, alternating between 755nm and 1064nm is the most effective approach, because beard hair is deep and thick."

The Real Reason Men's Beards Are Hard to Remove

"My beard is naturally thick—isn't that just something I have to live with?"

I hear this from patients fairly often,
and they're half right, half wrong.

Yes, the beard is thick,
but that alone isn't why hair removal doesn't work.

The real issue lies in the location and structure of the follicles (hair roots).

Men's beard follicles are located
about 1.5 to 2 times deeper than typical arm or leg hair.

The hair shafts themselves are also significantly thicker.

Laser hair removal works by being absorbed by melanin—the pigment inside the hair—
which converts to heat and destroys the follicle.

But here's the key point.

The depth to which a laser penetrates the skin
depends on its wavelength.

The longer the wavelength, the deeper it reaches;
the shorter the wavelength, the more energy is released near the surface.

The 755nm Alexandrite wavelength
has high melanin absorption, making it highly effective on darkly pigmented hair.

However, its skin penetration depth is relatively shallow.

The 1064nm Nd:YAG wavelength
has lower melanin absorption but significantly stronger deep tissue penetration.

Beard hair is deep and thick.

That means 755nm alone, which acts more superficially,
may not deliver enough energy all the way down to the follicle root,

while 1064nm alone
loses energy efficiency due to lower melanin absorption.

This is where it gets a bit tricky.
Some patients ask, "Can't you just turn up the energy?"

Cranking up the energy indiscriminately
can damage the skin surface first.

That raises the risk of burns or post-inflammatory hyperpigmentation.

That's why alternating between 755nm and 1064nm became the solution.

Each wavelength compensates for what the other can't fully cover.

This is also why GentleMax Pro Plus
is widely used for beard hair removal.

It allows seamless switching between both wavelengths within a single device.

For reference, the foundational research on wavelength-specific melanin absorption in laser hair removal is available through laser hair removal studies on PubMed, the U.S. National Library of Medicine.

👨‍⚕️ Dr. Youngjin Wi's key takeaways:

Fair skin + dark beard → Good response to 755nm, but 1064nm should be combined due to follicle depth

Darker skin tone → 755nm alone raises the risk of burns; a higher proportion of 1064nm is needed

Deep follicles + coarse beard → Without alternating both wavelengths, energy may not reach the root

How 755nm and 1064nm Are Used Alternately

GentleMax Pro Plus
is a device that can instantly switch between
755nm Alexandrite and 1064nm Nd:YAG wavelengths within a single platform.

Here's how I typically approach beard hair removal.

First, I use 755nm to deliver energy to the melanin in the hair near the surface.

This wavelength has high reactivity to beard hair,
which tends to be darkly pigmented and coarse.

Second, I follow up with 1064nm to fill in the gaps.

This delivers additional energy
to the deeper follicle areas that 755nm may not have fully reached.

To be candid,
patients who had been receiving beard hair removal using a single-wavelength device
often tell us after just 2–3 sessions here that
"this feels completely different from before."

It's not just a device difference—it's a difference in how the wavelengths are used.

In my experience, beard hair removal
is generally planned for around 6–8 sessions.

Intervals of 4–6 weeks are standard,
but because beard hair tends to have a shorter growth cycle,
the interval is sometimes set slightly shorter than for other areas.

"I've had 10 sessions and it still hasn't reduced enough."

When I look into cases like this,
it's often because energy settings were kept too low at each session,
or only a single wavelength was repeated without ever switching.

But there's one important caveat.

For patients with darker skin tones,
increasing the proportion of 755nm can overstimulate the skin's own melanin,
potentially leading to post-treatment hyperpigmentation.

This is an unfortunate limitation,
so for these patients, I increase the 1064nm proportion
and handle the energy settings with extra care.

Under the standard skin type classification (Fitzpatrick scale),
wavelength selection needs to be approached more cautiously for Type IV and above.

That said, for those with dense beards and deep follicles,
the dual-wavelength approach remains the most effective option available.

If you're curious about how this compares to other hair removal methods,
take a look at our full laser hair removal guide as well.

👨‍⚕️ Dr. Youngjin Wi's key takeaways:

755nm alone: High melanin absorption / Limited reach to deep follicles / Best suited for fair skin

1064nm alone: Strong deep penetration / Lower melanin absorption reduces energy efficiency / Safer for darker skin tones

Dual-wavelength combination: Most effective for deep, thick hair like beards / Wavelength ratio must be adjusted based on skin tone

What You Need to Know Before and After Treatment

This is one of the most common misconceptions,
but you must shave the day before your laser hair removal session.

If the laser is applied while beard hair is still protruding above the skin,
the energy gets consumed at the surface
and never fully reaches the follicles.

It also significantly increases the risk of surface burns.

After treatment, it's normal for the area to be slightly red or mildly swollen around the follicles for about 2–3 days.

In my experience, this settles within 1–3 days in most cases,
and severe reactions are rare.

There's one thing I always make a point of explaining upfront:
rather than complete elimination, a realistic goal for beard hair removal is
an 80–90% reduction.

Because beard hair is influenced by hormones,
there is a slightly higher chance of regrowth compared to other areas,
and some fine hairs may return over time.

This is something I always discuss with patients before we begin.

Dr. Youngjin Wi reassesses wavelength ratios and energy settings at every session
based on how the skin is responding.

The settings used at sessions 1, 3, and 5 onward
are not the same.

As follicles are destroyed and the remaining hair becomes finer and less dense,
the wavelength strategy needs to adapt accordingly.

👨‍⚕️ Dr. Youngjin Wi's key takeaways:

Shave the day before (mandatory) → Improves energy delivery efficiency to the follicles

Mild redness and swelling for 2–3 days after treatment is normal → Usually resolves on its own

An 80–90% reduction is the realistic goal for beard hair removal, not complete removal → Set expectations accordingly before starting

Key takeaway: If repeated beard hair removal isn't producing results, the problem may be wavelength selection. Because beard hair is deep and thick, alternating between 755nm and 1064nm is essential to deliver energy effectively all the way to the follicle root.

Frequently Asked Questions

Q1. Is there a specific area that hurts the most during beard hair removal?

A. Yes.

The area just below the upper lip, around the philtrum, has a high density of nerve endings,
and many patients feel stronger pain there.

GentleMax Pro Plus has a built-in Dynamic Cooling Device (DCD)
that sprays a cooling mist onto the skin surface just before each laser pulse,
which helps reduce discomfort to a noticeable degree.

That said, it still hurts,
so we always give sensitive patients a heads-up before we begin.

Q2. My skin is on the darker side—is beard hair removal still an option for me?

A. Yes, but wavelength selection is critical.

The darker the skin tone, the more we reduce the proportion of 755nm
and lean toward 1064nm to lower the risk of hyperpigmentation.

Turning up the energy indiscriminately
or proceeding with 755nm alone
can leave the skin looking uneven or patchy afterward,
so assessing skin tone first and setting the wavelength ratio accordingly is essential.

Q3. I've heard skin can become rough after beard hair removal—is that true?

A. When treatment is performed properly, this is uncommon.

However, if energy settings are too high
or sessions are spaced too closely together, the skin doesn't have enough time to recover,
and changes in surface texture can occur.

In my experience, as long as you maintain at least a 4-week interval
and keep up with moisturizing and sun protection after treatment,
texture issues are rare.

Post-treatment care is part of the result.

Feel free to reach out with any questions via KakaoTalk or phone.

We also welcome patients from near Hapjeong Station, Hongdae, Sinchon, and Ewha,
and we're open on Sundays.
