Hello.

This is We Yong-jin, the chief director.

​

Daily shaving is surprisingly a big stress.

The beard that grows back quickly makes it dark again after just one day,

and if the skin gets irritated and trouble arises, it becomes even more cumbersome.

​

For this reason, many men consider male laser hair removal.

However, surprisingly, I often hear stories that there was no significant change even after 5 or 10 sessions.

​

Why do such results occur?

Today, I will discuss the reasons in a bit more detail.

​

💡 How does male laser hair removal work?

Male laser hair removal is

not just a procedure to remove surface hair.

​

It directly destroys the stem cells in the hair follicles

to prevent hair from growing back.

​

✔️When a specific wavelength of the laser is absorbed by the melanin pigment in the hair, heat is generated,

✔️this heat is transmitted to the hair roots and stem cells, leading to destruction.

​

If this process is done properly, the beard gradually becomes thinner and less dense,

and ultimately, you can feel a significant reduction in shaving frequency.

​

However, not everyone experiences the same results.

​

Due to differences in hair thickness and depth, skin thickness, and melanin concentration,

the required energy intensity and number of sessions vary.

​

For example,

👉 areas like the chin or philtrum, where the roots are deep and thick, require stronger energy,

👉 while fine hair, like vellus hair, requires shorter pulse widths and precise settings.

​

If these differences are not considered and treatments are done uniformly,

the hair removal effect weakens, and you may experience hair growing back even after several sessions.

​

Moreover, male laser hair removal is not a one-time procedure.

​

Because hair goes through the growth–regression–resting cycles, it must be treated multiple times.

Typically, you should receive at least 5 to 10 sessions for a noticeable change.

⚙️ The first key to male laser hair removal

: Energy control

The biggest factor determining the treatment effect is energy settings.

​

To completely destroy the stem cells, sufficient heat is required, but

due to the desire to avoid burns or pigmentation, many treat with too weak of a strength.

​

In this case, hair may appear to be reduced temporarily, but it will ultimately grow back.

​

Conversely,

if the energy is excessively high, it poses a risk of damaging not only the hair follicles but also the surrounding skin tissue.

At this stage, side effects such as burns, folliculitis, and pigmentation may occur.

​

Therefore, what is important is

to carefully assess the skin type, hair thickness, depth, and melanin levels

and adjust the energy accordingly for each individual.

​

Men's beards are much thicker and deeper than women's body hair.

​

So if the energy is insufficient, the effect decreases,

and if it is too strong, pain and side effects increase.

​

Ultimately, the degree of precision with which an experienced medical staff adjusts will determine whether

you see no change after 10 sessions or feel changes after only a few.

​

⚙️ The second key to male laser hair removal

: Equipment

Another easily overlooked factor is laser equipment.

​

Each device has different wavelengths, pulse widths, and cooling methods, leading to significant differences in effectiveness and irritation.

Especially, pulse width is a very important variable in removing both thick and fine hair.

Some older devices have a narrow pulse control range, which may not adequately remove thin or deep hair.

​

For instance, the GentleMax Pro Plus

can finely adjust the pulse width in units of 2ms,

effectively dealing with both thick beards and thin vellus hair.

​

Additionally, even during high-output treatments, it features a gas cooling system that protects the skin surface.

This allows for safe high-energy procedures.

​

Thus, if you are considering male laser hair removal, you should check what wavelengths the equipment used emits,

and whether it matches the characteristics of your beard.

​

✨ Summary of Key Points

1️⃣ Directly destroying stem cells can lead to a semi-permanent effect.

​

2️⃣ If the energy is weak, sufficient destruction of stem cells does not occur.

​

3️⃣ Ultimately, what determines the effect is energy control and equipment selection.
