3 months after finishing hair removal,

if hair starts showing again

now is the golden time

Let me start with the conclusion.

Hair removal is not a procedure that has a "finish" line.

I’ll explain why in this article.

You finished hair removal, so why is it showing again?

Here’s the thing

This is a point many people misunderstand,

because they think, "I already had 8 or 10 sessions

so it should never grow back now."

But the tricky part is that laser hair removal only destroys

hair follicles that are in the anagen phase at that time.

Hair grows by cycling through the anagen, catagen, and telogen phases

over and over again.

Follicles that were in the telogen phase at the time of treatment

receive almost no laser energy.

So even people who have finished all 8 to 10 sessions may notice, 2 to 3 months later,

that the follicles that were in the telogen phase then

start waking up and become visible again.

Why is it that after the same 8 sessions

some people look smooth

while others see hair again?

Director Wi Young-jin’s

key insight

If you do about 5 more sessions at the 3-month point after the last treatment,

you can keep the smoothest result

for much longer.

Last month, a 33-year-old woman came in after

completing 8 sessions of underarm hair removal at another clinic,

and about a year had passed.

In the exam room, I could see fine hairs

popping up again in spots,

but this was not because the previous treatment was wrong; it is

a completely normal process.

There is one really important thing here.

The 3-month point after the last treatment is the most efficient time

to start the "additional 5 sessions."

That’s because the follicles that had been hidden in the telogen phase

are just now returning to the anagen phase.

If you do about 5 more sessions at this time with an alexandrite or Nd:YAG laser,

you can maintain a smooth result much longer

than when the first series ended.

Director Wi Young-jin’s key takeaway

Hair removal is not about "finishing"; it’s about "maintaining."

If hair starts showing again after 3 months,

that’s a natural sign that telogen-phase follicles have awakened.

If you get about 5 more sessions at this point,

you can keep the smoothest result for much longer.

Recommended additional treatment guide by current condition

However, facial areas like the chin or upper lip are

greatly affected by hormones,

so please note that even these sessions may not completely control them.

If you’ve read this far,

you’re probably wondering this

Q1. I had it done at another clinic—

can I get additional treatment here?

Yes, if the laser type is similar,

your previous treatment history will not have a major impact.

Just let us know which laser was used

and how many sessions you had at your first visit.

Q2. Can’t I just let it grow back?

The cost is a burden.

It’s your choice.

But rather than leaving it alone for 2 to 3 years

and starting over from scratch with 8 sessions,

adding 5 sessions now is

far more efficient in terms of total cost and time.

Q3. What are the side effect risks with additional treatment?

Because the number of follicles has already decreased,

the burden on the skin is much less than it was at the beginning.

Temporary redness or swelling

will calm down in a day or two, so don’t worry.

In the next article, I’ll explain "the first 2 weeks after additional hair removal,

and the changes that are actually visible in the exam room."
