A Criteria Guide by Cause
“Hair loss treatment” covers very different approaches depending on what’s actually causing the shedding. This guide explains how hair loss type is diagnosed and how treatment is matched to cause rather than applied generically.
What’s the fastest way to know which hair loss treatment fits me? Gradual, pattern-shaped thinning usually points to androgenic hair loss, treated with topical or oral medication and sometimes PRP or laser therapy, while sudden diffuse shedding often points to telogen effluvium, treated by identifying and resolving the trigger — a consultation with bloodwork is the reliable way to tell them apart rather than guessing from symptoms alone.
Why “Hair Loss”
Isn’t One Diagnosis
Hair loss is a symptom, not a single condition — the underlying cause can be genetic pattern loss, a temporary reaction to stress or illness, an autoimmune process, or a nutritional or hormonal factor, and each of these responds to a different kind of treatment. Androgenic (pattern) hair loss, the most common type in both men and women, is driven by genetic sensitivity to DHT and follows a fairly predictable, gradual pattern over years. Telogen effluvium, by contrast, is a sudden, diffuse shedding usually triggered by a specific event — significant stress, illness, rapid weight change, or childbirth — that resolves once the trigger is addressed.
Because these causes require genuinely different treatment approaches, an accurate diagnosis matters more for hair loss than for almost any other cosmetic dermatology concern. A consultation that includes a scalp exam and, when relevant, bloodwork to check thyroid function, iron levels, or hormonal markers is the starting point for any realistic treatment plan. For a broader look at finding the right specialist, see Dermatologist in Korea.
The Main
Hair Loss Types
Androgenic (pattern) hair loss
Genetically driven, gradual thinning — receding hairline or crown loss in men, diffuse part-line thinning in women. The most common type, and typically progressive without treatment.
Telogen effluvium
Sudden, diffuse shedding triggered by stress, illness, rapid weight change, or childbirth, usually appearing 2–3 months after the triggering event. Often resolves once the trigger is addressed.
Alopecia areata
An autoimmune condition causing patchy, well-defined bald spots. Requires different treatment from pattern loss and is typically evaluated separately at consultation.
Nutritional or hormonal contributors
Iron deficiency, thyroid dysfunction, and certain hormonal shifts can contribute to or worsen shedding, which is why bloodwork is often part of an accurate diagnosis.
Female pattern hair loss deserves a specific note, since it’s often overlooked or misdiagnosed compared to the male version. Rather than a receding hairline, it typically shows as gradual widening of the part line and overall thinning across the crown while the frontal hairline stays relatively intact — a pattern easy to mistake for telogen effluvium if the gradual timeline isn’t considered carefully. Hormonal factors, including thyroid function and, less commonly, polycystic ovary syndrome, are more frequently relevant contributors in women and are typically screened for during workup.
Treatment Options
Matched to Cause
| Option | Best For | Typical Course | Notes |
|---|---|---|---|
| Topical minoxidil | Androgenic loss, first-line | Daily, ongoing | Requires consistent long-term use |
| Oral medication (finasteride/dutasteride) | Androgenic loss, moderate-advanced | Daily, ongoing | Prescription, candidacy discussed at consultation |
| PRP (platelet-rich plasma) | Supporting existing follicles | 3–4 sessions | Often combined with medication |
| Low-level laser therapy | Mild-moderate loss, maintenance | Ongoing, at-home or in-clinic | Supports rather than replaces other treatment |
| Hair transplant referral | Advanced, stable pattern loss | One-time procedure | Evaluated case by case |
Telogen effluvium generally isn’t treated with these options directly — the priority is identifying and resolving the trigger, with supportive care in the meantime.
Choosing
By Your Case
Early pattern loss
Topical minoxidil alone is often a reasonable starting point, with oral medication added if progression continues despite consistent use.
Moderate pattern loss
A combination of oral medication and PRP tends to produce a stronger response than either alone, and is commonly recommended together.
Sudden, diffuse shedding
Bloodwork and a review of recent life events (illness, stress, diet, childbirth) usually take priority over starting hair-loss-specific treatment immediately.
Advanced, stable pattern loss
A transplant evaluation is discussed alongside continued medical management, since medication alone is less likely to restore significant density at this stage.
What to Expect
Across Treatment
- Month 1–2
Shedding may temporarily increase
Some patients notice a brief increase in shedding when starting minoxidil, as the hair cycle resets — this is expected and typically settles.
- Month 3–6
Initial response visible
Reduced shedding and early signs of density improvement typically become visible in this window for patients on consistent treatment.
- Month 6–12
Fuller assessment of response
This is generally when treatment effectiveness is more clearly assessed, and the plan adjusted — continuing, adding PRP, or considering other options.
- Ongoing
Long-term maintenance
Androgenic hair loss treatment is generally ongoing rather than a fixed course, since stopping treatment typically allows progression to resume.

Hair loss diagnosis benefits from continuity — seeing the same provider across several months makes it easier to judge whether a treatment is actually working versus normal month-to-month variation in shedding.
Common Mistakes
That Delay Results
Stopping treatment as soon as shedding slows is one of the most common setbacks, since androgenic hair loss treatment is generally maintenance-based — the underlying genetic sensitivity to DHT doesn’t go away, so progression tends to resume once medication stops. Patients sometimes interpret an early plateau as “cured” and discontinue, only to see loss continue months later.
Judging results too early is another frequent issue — because the hair growth cycle takes months, checking progress weekly or comparing photos taken only a few weeks apart rarely shows a meaningful trend either way. And treating a sudden shedding episode as pattern loss without ruling out a treatable trigger like thyroid dysfunction or iron deficiency can mean months spent on the wrong approach when the actual fix was addressing the underlying cause directly.
Frequently Asked
Questions
- How do I know if my hair loss is androgenic or something else?
- Androgenic (pattern) hair loss typically follows a predictable pattern — receding hairline or crown thinning in men, diffuse thinning at the part line in women — and progresses gradually over months to years. Sudden, diffuse shedding across the whole scalp is more often telogen effluvium, usually triggered by stress, illness, or a nutritional change, and a consultation with bloodwork can help distinguish between the two.
- Is hair loss treatment reversible?
- Telogen effluvium is often reversible once the underlying trigger is identified and resolved, with regrowth typically visible within several months. Androgenic hair loss is progressive and treatment generally focuses on slowing further loss and supporting existing follicles rather than fully reversing loss that occurred years earlier, though early treatment tends to preserve more hair long-term.
- How long before hair loss treatment shows results?
- Topical and oral medication typically require 3–6 months of consistent use before a meaningful difference in shedding or density becomes visible, since hair growth cycles are inherently slow. PRP courses are usually reassessed after 3–4 sessions spaced about a month apart.
- Is finasteride or dutasteride available in Korea, and is it safe?
- Oral medications like finasteride and dutasteride are available in Korea by prescription following medical evaluation, and are generally considered effective for androgenic hair loss in appropriate candidates. Potential side effects and candidacy are discussed at consultation, since these medications aren’t suitable for everyone.
- When is a hair transplant the right next step?
- A hair transplant is typically considered when pattern loss has progressed to the point that medication and PRP alone are unlikely to restore meaningful density, or when a patient wants a more definitive result than ongoing maintenance treatment provides. This is evaluated case by case rather than at a fixed loss percentage.
