Seolleung Dermatology <Treatment> Hair Loss Follicle Injections: A Comprehensive Guide to Effects, Side Effects, and Safety

Hello.

I am Kim Da-jung, the head director of Cordia Clinic.

You've probably heard of hair loss follicle injections at Seolleung Dermatology at least once.

However, imagining injections directly into the scalp might make some people feel a shiver down their spine.

‘Will it hurt?’ ‘Is it safe to inject something into my scalp?’ ‘Does it really work?’

These thoughts often come one after another.

That's perfectly understandable.

So today, at Seolleung Dermatology, I'll explain step-by-step how hair loss follicle injections work, what ingredients are used, and whether they are truly safe.

It's never too late to make a decision after you have all the information.

<Treatment Philosophy>

How exactly do they make hair grow?

As the name suggests, it's a procedure that directly injects medication into the scalp.

Oral medications have to pass through the stomach, enter the bloodstream, and travel to the scalp, a process that dilutes their concentration and takes a long time.

Hair loss follicle injections at Seolleung Dermatology bypass these steps, delivering the medication directly to where it's needed.

Hair loss is a process where hair follicles gradually shrink, causing thick, healthy hair to become thin, short, and downy.

Eventually, the hair weakens to the point where it cannot grow sufficiently above the scalp.

Therefore, the goal is to directly provide nutrition and stimulation to these weakened areas to reactivate them.

The injections penetrate the scalp surface at a very shallow depth.

Many people worry about pain, but we apply anesthetic cream beforehand and use a target cooler to minimize discomfort, so you don't need to worry too much.

Let's look at what goes into hair loss follicle injections.

At Cordia Clinic in Seolleung Dermatology, we use growth factors in conjunction with Botox.

Many people find this surprising.

This is because Botox is typically known for wrinkle reduction.

However, recent studies continue to confirm that Botox is also effective in treating hair loss.

The principle is as follows:

When scalp muscles are tense, blood flow to the hair follicles decreases.

Botox relaxes this tension, improving blood circulation and allowing better delivery of oxygen and nutrients.

Even more interestingly, there is experimental evidence that Botox reduces a factor called TGF-β in dermal papilla cells, which causes hair shedding.

A systematic review published in the Dermatologic Therapy journal in 2026 showed that botulinum toxin treatment was effective for androgenetic alopecia, with hair density increasing by 13-20% within 12-24 weeks, and hair diameter improving from the 3-month mark.

Another study showed an efficacy rate of 73.3% for the Botox monotherapy group and 84.8% for the finasteride combination group.

When growth factors are added, the effect is even more synergistic.

Growth factors are proteins that directly stimulate the proliferation of dermal papilla cells.

Botox creates the optimal environment, while growth factors directly nourish the hair follicles, thus dividing their roles.

The exact composition is proprietary to each clinic and difficult to disclose, but these two pillars are the core of hair loss follicle injections.

So, is it safe?

This is probably your biggest concern.

To put it simply, if appropriate dosages and precise injection techniques are followed, it is a procedure with well-established safety.

Common side effects include temporary redness, slight tenderness, and minor bruising, most of which subside within a day or two.

After the procedure, as long as you avoid washing your hair on the same day, there is almost no disruption to daily life.

However, safety depends not only on the ‘medication itself’ but also on ‘who performs the procedure and how.’

This is because the injection depth, distribution, and dosage all vary depending on the medical professional's skill.

Therefore, when considering hair loss follicle injections, it's crucial not to just look at prices or reviews, but to ensure that the medical professional performing the procedure has a thorough understanding of the scalp and hair.

Hair loss is an area where recovery becomes more difficult the longer it is delayed.

I hope you will research thoroughly, consult with a trustworthy medical professional, and find the right approach for you.

Thank you.

This has been Kim Da-jung, Head Director of Cordia Clinic.
