Hair Loss Treatment in Seoul: Medical Plans for Regrowth
The short answer
A hair loss treatment program in Seoul combines scalp diagnosis and blood tests with proven medication, PRP or exosome injections, low-level laser and scalp care to slow shedding and support regrowth. In Gangnam an in-clinic session such as PRP typically costs about ₩200,000–₩600,000, sessions take 30–60 minutes, and downtime is minimal. Visible improvement usually takes 3–6 months, so consistent treatment is essential.

Start with the cause
Hair loss has many causes, and the right treatment depends on finding the main one. The most common is androgenetic alopecia, or pattern hair loss, driven by genetics and hormones. Other causes include stress-related shedding (telogen effluvium), iron or vitamin deficiencies, thyroid problems, scalp inflammation, tight hairstyles and autoimmune conditions such as alopecia areata. A good program in Seoul begins with a consultation, magnified scalp imaging and, often, blood tests, so treatment targets the real problem. Our page on blood tests for hair loss in Gangnam explains what is commonly checked.
Building blocks of a program
| Treatment | How it helps | Typical schedule |
|---|---|---|
| Minoxidil | Prolongs the growth phase and enlarges follicles | Daily, ongoing |
| Finasteride or dutasteride | Reduces DHT, a key driver of pattern loss | Daily, if suitable |
| PRP | Platelet growth factors support follicles | Monthly for 3–4 sessions, then maintenance |
| Exosome therapy | Signalling molecules support scalp repair | Every 2–4 weeks in a course |
| Low-level laser | Light energy stimulates follicles | Several times a week |
| Medical scalp care | Treats inflammation, oil and flaking | Weekly to monthly |
Medication choices depend on your sex, age, medical history and plans for pregnancy, so they should always be prescribed by a doctor after a full discussion of benefits and side effects.
What an in-clinic session looks like
For PRP, a small blood sample is taken and spun to separate platelet-rich plasma. The scalp is numbed with cream or a cooling device, and the PRP is injected across thinning areas with fine needles or an injector. Exosome or booster treatments follow a similar process or use microneedling. Sessions usually take 30 to 60 minutes. You may feel tenderness for a day, and you can usually wash your hair the next day.
Timeline and expectations
- Months 1–2: shedding may temporarily increase as weak hairs are replaced
- Months 3–4: shedding slows; new fine hairs may appear
- Months 6–12: improved density and thicker strands for many patients
Treatments generally maintain and improve existing follicles rather than regrow hair on completely bald areas. Stopping medication usually allows pattern loss to resume, so long-term commitment matters.
When to consider a hair transplant
If areas have been bald for a long time, follicles may no longer respond to treatment. In that case, a hair transplant can move healthy follicles to thinning areas, and medical treatment helps protect the remaining hair. Many Gangnam clinics offer both approaches.

Lifestyle factors that help
- Eat enough protein, iron and zinc, and correct any proven deficiencies
- Manage stress and sleep, which influence shedding
- Avoid tight hairstyles and excessive heat styling
- Treat dandruff or scalp inflammation promptly
- Avoid crash diets, which often trigger temporary shedding
Planning treatment from abroad
Because hair loss treatment takes months, international patients usually start with a full diagnosis and an initial PRP or exosome session in Seoul, then continue medication and home care, returning periodically for in-clinic sessions. Ask the clinic for written results of your tests, a medication plan in English and whether follow-up can be done remotely with photos. Check whether prescribed medications are permitted to take home in your country.
Questions to ask the clinic
- What do you believe is causing my hair loss?
- Which treatments are evidence-based for my type of loss?
- How will you measure progress over time?
- What is the total cost of a six-month plan?
Taking standardised photos of your hairline and crown every month, in the same light, is one of the simplest ways to judge whether a plan is working.
