"These days, I see a lot of people getting laser treatment for underarm hair removal.

Does that really mean the hair won’t grow back?"

"Shaving or waxing seems simpler...

Why do people get it?"

Among body hair areas, the underarms are one of the parts that can feel more noticeable and burdensome when exposed.

Because they can give an impression of looking less feminine or unclean, many people regularly manage them with shaving or waxing.

However, recently, laser hair removal has been getting more attention among the various hair removal methods.

As a result, people who have been shaving or waxing before may wonder, “Wouldn’t it be inconvenient to keep visiting the clinic?”

So why do so many people choose laser hair removal?

Today, I’ll explain the reasons in detail.

It can’t be said that shaving and waxing are completely wrong methods.

Shaving is a method of cutting the surface of the hair with a sharp blade, and waxing is a method of pulling the hair out, so both have the advantage of being easy to do at home.

However, the biggest problem is pigmentation caused by repeated irritation.

Both methods continuously irritate the skin, so the area often becomes more sensitive over time, which can lead to pigmentation.

In particular, with shaving, the cross-section of the hair is left exposed, so when it grows back, it can look rougher and less clean.

For these reasons, laser hair removal is being considered as an alternative because it can reduce skin irritation while providing a relatively longer-lasting effect.

Laser hair removal can be applied not only to the underarms but also to various other areas.

At this time, it is important to know that the suitable device and wavelength differ by area.

Basically, the principle of destroying the hair root is the same, but depending on the wavelength used, the types of hair that can be removed effectively differ.

For example, the underarm skin is relatively thin, but the hair is coarse and the hair roots tend to be deep.

Therefore, it is important to choose a device that can protect the skin surface while delivering energy deep into the hair root.

However, even with an appropriate device, the procedure cannot be completed in just one session.

This is not a problem with the device, but rather because of the hair growth cycle.

Hair goes through the anagen, catagen, and telogen phases, and laser hair removal works most effectively on hairs in the “anagen” phase, when melanin pigment is abundant.

Therefore, hairs in the catagen or telogen phase can only be removed later, after they move into the anagen phase.

Since not all hairs have the same cycle, it is important to gradually complete the hair removal effect through repeated sessions.

Laser hair removal is often described as “semi-permanent.”

You may wonder, “If it’s permanent, wouldn’t it be completely over?” but there is a reason for the term semi-permanent.

Laser hair removal uses energy that reacts to melanin pigment to destroy the hair root, and once the hair root is destroyed, it is difficult for the hair to grow back.

However, over time, some hair roots may recover, or fine vellus hair that was previously not very noticeable may gradually become thicker and more visible.

These fine hairs have little melanin content, so they are not noticeable at first, but over time they can change into terminal hair, which makes it feel like the hair has grown back.

Of course, it is not something that needs to be managed as often as shaving or waxing,

and if you receive about 2 to 3 additional sessions after the hair grows back, you can maintain the hair removal effect for a long time.

Many people may also be considering Hongdae laser hair removal.

Because you have to visit a dermatology clinic and repeated sessions are needed, you may be wondering whether to manage it at home instead.

Of course, shaving or waxing can also be an option, but you may find them inconvenient because they repeatedly irritate the skin and require frequent maintenance.

If you want to keep the area neat for a longer period of time, considering laser hair removal may be a good choice.
