The reason laser hair removal was ineffective

Shaving every morning is a bigger stress than you might think.
Hello.
This is Wi Yeong-jin from Beauty Doctors.
With the beard that grows back quickly
even after just one day, it becomes dark,
and if the skin gets irritated,
it leads to more trouble.
For this reason, many men
consider male laser hair removal.
However, surprisingly, after receiving treatment 5 or 10 times,
I've heard stories of not seeing much change.
Why does this result occur?
Today, I will discuss the reasons in a little 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 the hair from regrowing.
When a specific wavelength of the laser
is absorbed by the melanin in the hair, heat is generated,
and this heat is transmitted to the hair root and stem cells,
leading to destruction.
If this process occurs correctly,
the beard gradually becomes finer and less dense,
and you can feel a noticeable reduction in
the number of shavings.
However, not everyone
will see the same results.
Because the thickness and depth of hair, skin thickness, and melanin concentration
determine the required energy intensity and frequency.
For instance, areas with deep and thick roots like the chin or the philtrum
require stronger energy, while
thin hairs like vellus hairs require shorter pulse widths and
precise settings.
If you don't consider these differences and apply treatment uniformly,
the hair removal effect weakens,
and even after several treatments,
you will experience hair growing back.
Also, male laser hair removal is not a one-time treatment.
Hair goes through a cycle of growth – regression – and resting,
so it needs to be treated multiple times.
Typically, more than 5 to 10 sessions are needed to
feel a significant change.
⚙️ The first key to male laser hair removal
: Energy control
The biggest factor determining the effectiveness of the treatment is energy settings.
To completely destroy the stem cells,
sufficient heat is necessary, but
due to the desire to avoid burns or pigmentation,
it is often done with too weak a strength.
In such cases, the hair may seem to decrease temporarily, but
eventually, it will grow back.
On the other hand, if the energy is excessively high,
there is a risk of damaging not only the hair follicles but also
the surrounding skin tissue.
In this case, side effects such as burns, folliculitis,
and pigmentation can occur.
Therefore, it is important to accurately assess skin type, hair thickness,
depth, and melanin level and then
individually adjust the energy.
Men's facial hair is much thicker and has deeper roots than
women's body hair.
So, if the energy is insufficient, the effect decreases, while
if it's too strong, pain and side effects increase.
Ultimately, how delicately a skilled medical professional
adjusts the settings will determine
whether nothing changes after 10 sessions or
whether you feel changes after just a few sessions.
⚙️ The second key to male laser hair removal
: Equipment
Another easily overlooked factor is
the laser equipment.
Each device has different wavelengths, pulse durations, and cooling methods,
resulting in significant differences in effectiveness or irritation levels.
Especially, pulse duration is very important for removing both thick and thin hairs.
Some older devices have a narrow range for pulse adjustments,
which can lead to inability to effectively remove thin or deep hairs.
For example, the GentleMax Pro Plus can finely adjust the pulse width in 2ms units,
allowing it to handle not only thick beards but also fine vellus hairs.
Moreover, during high-power treatments, a gas cooling system is built-in to protect the skin's surface.
This allows for the safe conduct of high-energy treatments.
Therefore, if you are considering male laser hair removal,
make sure to check what wavelength the equipment emits,
and whether it is suitable for your beard type.
✨ Summary of Key Points
1️⃣ Directly destroy stem cells to
expect semi-permanent effects.
2️⃣ If the energy is weak, stem cell destruction
does not occur sufficiently.
3️⃣ Ultimately, what determines the effect is
energy control and equipment selection.
