Because the follicles are <strong>not destroyed<\/strong> in the early and middle stages, treatment can be genuinely effective if started before the miniaturisation process is complete.<\/p>\n<h3>How Is AGA Diagnosed?<\/h3>\n<p>A dermatologist or plastic surgeon will typically take a thorough medical history and perform a scalp examination, often using a dermatoscope \u2014 a handheld magnifying device that allows close inspection of follicle density and miniaturisation.<\/p>\n<p>Blood tests may be ordered to rule out thyroid dysfunction, iron-deficiency anaemia, or other systemic causes of hair loss before confirming an AGA diagnosis.<\/p>\n<h2>Treatment Options for AGA Available in Tokyo<\/h2>\n<figure style=\"margin: 1.5em 0;\"><img decoding=\"async\" style=\"width: 100%; max-width: 100%; height: auto; border-radius: 8px;\" title=\"Hair loss treatment Tokyo: AGA options for expats \u2014 Treatment Options for AGA Available in Tokyo\" src=\"https:\/\/kojihifu.com\/english\/wp-content\/uploads\/2026\/07\/pexels_28994388_1784545147.webp\" alt=\"Hair loss treatment Tokyo: AGA options for expats \u2014 Treatment Options for AGA Available in Tokyo\" \/><figcaption style=\"font-size: 0.8em; color: #888; text-align: right; margin-top: 4px;\">Photo: Pexels \/ Beyzanur K.<\/figcaption><\/figure>\n<p>The landscape of AGA treatment has evolved considerably, and patients in Tokyo have access to the same evidence-based options found in major cities worldwide. These broadly fall into three categories: pharmaceutical treatments, topical agents, and procedural or device-based therapies.<\/p>\n<h3>Oral and Topical Medications<\/h3>\n<p><strong>Finasteride<\/strong> is an oral prescription medication that inhibits the enzyme 5-alpha reductase, thereby reducing DHT levels in the scalp. It is the most extensively studied pharmacological treatment for male AGA.<\/p>\n<p><strong>Dutasteride<\/strong> works through a similar mechanism but inhibits both isoforms of the enzyme and may offer greater DHT suppression; it is<strong> widely prescribed in Japan<\/strong>. Both medications are approved by the relevant Japanese regulatory authorities for male AGA and require a prescription from a licensed physician.<\/p>\n<p><strong>Minoxidil<\/strong>, available in both topical and low-dose oral formulations, works by a different mechanism: it prolongs the anagen phase and improves blood flow around the follicle. Topical minoxidil is available over the counter in Japan, while oral (systemic) minoxidil requires a prescription and is used off-label for hair loss in carefully selected patients.<\/p>\n<p>Clinical reports indicate that finasteride at 1 mg daily leads to a measurable increase in hair count in the majority of men after 12 months of continuous use, with studies suggesting that <strong>approximately 83\u201390% of men e<\/strong>xperience either stabilisation of hair loss or visible regrowth at two years of treatment. These figures are drawn from double-blind randomised controlled trials and reflect results with consistent adherence; individual outcomes vary.<\/p>\n<h3>Procedural Treatments: PRP Therapy<\/h3>\n<p><strong>Platelet-rich plasma (PRP) therapy<\/strong> involves drawing a small amount of the patient&#8217;s own blood, concentrating it in a centrifuge to increase the proportion of platelets and growth factors, and then injecting the resulting solution into the scalp. Platelets contain growth factors such as <strong>PDGF, VEGF, and IGF-1<\/strong> that are thought to stimulate follicular activity and prolong the anagen phase.<\/p>\n<p>Studies suggest that PRP injections can produce a statistically significant increase in hair density and thickness compared with placebo, with one systematic review reporting mean <strong>improvements in hair count ranging from 15 to 30 hairs per cm\u00b2<\/strong> across multiple controlled trials. PRP is not a replacement for medication in moderate-to-severe AGA, but it is often used as a complementary approach to enhance results from pharmacological treatment.<\/p>\n<h3>Low-Level Laser Therapy (LLLT)<\/h3>\n<p>Low-level laser (or light) therapy uses specific wavelengths of red or near-infrared light to stimulate follicular metabolism. It is available as in-clinic devices and cleared for use in hair loss in several regulatory jurisdictions. LLLT is generally considered an adjunctive option rather than a standalone treatment for significant AGA.<\/p>\n<h3>Nutritional and Supportive Therapies<\/h3>\n<p>Deficiencies in iron, zinc, vitamin D, and certain amino acids have been associated with hair thinning, though they are not the primary driver in true AGA. At <strong>BIOTOPE CLINIC or Kojimachi Dermatology &amp; Plastic Surgery Clinic,<\/strong> the preventive medicine menu includes nutritional therapy and IV drip therapy, which some patients find helpful as a supportive measure alongside first-line AGA treatments.<\/p>\n<p>If you are interested in assessing nutritional status as part of a hair health review, this is something that can be discussed during a consultation at our Ichigaya clinic.<\/p>\n<blockquote style=\"border-left: 4px solid #5a8a5a;

Clinical evidence consistently shows that the hair gained during treatment is typically lost within 6\u201312 months of stopping medication. Patients should understand from the outset that treatment is an ongoing commitment rather than a short course.<\/p>\n<p><strong>Misconception 2: &#8220;Expensive shampoos or herbal supplements can replace prescription treatment.&#8221;<\/strong> Over-the-counter scalp shampoos marketed for hair loss, as well as many herbal supplements, have little robust clinical evidence supporting their efficacy in true AGA. While scalp hygiene and general health are supportive factors, they cannot replicate the DHT-blocking or follicular-stimulating effects of prescription medications or PRP. Delaying proven treatment in favour of unproven alternatives risks allowing further follicular miniaturisation that becomes harder to reverse.<\/p>\n<h2>Who Is a Good Candidate for AGA Treatment?<\/h2>\n<figure style=\"margin: 1.5em 0;\"><img decoding=\"async\" style=\"width: 100%; max-width: 100%; height: auto; border-radius: 8px;\" title=\"Hair loss treatment Tokyo: AGA options for expats \u2014 Who Is a Good Candidate for AGA Treatment\" src=\"https:\/\/kojihifu.com\/english\/wp-content\/uploads\/2026\/07\/pexels_17553840_1784545151.webp\" alt=\"Hair loss treatment Tokyo: AGA options for expats \u2014 Who Is a Good Candidate for AGA Treatment\" \/><figcaption style=\"font-size: 0.8em; color: #888; text-align: right; margin-top: 4px;\">Photo: Pexels \/ Luis Quintero<\/figcaption><\/figure>\n<p>In our clinical experience at<strong> BIOTOPE CLINIC or Kojimachi Dermatology &amp; Plastic Surgery Clinic<\/strong>, the patients most likely to benefit from AGA treatment are those who seek evaluation at an early to moderate stage of hair loss, before widespread follicular miniaturisation has occurred. Candidates should be in generally good health and have realistic expectations \u2014 the goal of treatment is typically stabilisation and partial regrowth, not restoration of teenage-density hair.<\/p>\n<p><strong>Good candidates<\/strong> for pharmaceutical AGA treatment include men with early-to-moderate AGA (Norwood-Hamilton scale I\u2013IV) and women with female-pattern hair loss (Ludwig scale I\u2013II) after systemic causes have been excluded.<\/p>\n<p><strong>Who should approach treatment with caution or seek specialist review:<\/strong><\/p>\n<ul>\n<li>Women who are pregnant, planning pregnancy, or breastfeeding \u2014 finasteride and dutasteride are contraindicated in women of childbearing potential due to the risk of foetal harm<\/li>\n<li>Men with a personal or family history of prostate cancer or certain other androgen-sensitive conditions<\/li>\n<li>Patients with liver dysfunction, as finasteride and dutasteride are hepatically metabolised<\/li>\n<li>Individuals experiencing sudden or patchy hair loss, which may indicate alopecia areata or another dermatological condition requiring different management<\/li>\n<li>Those with significant scalp inflammation, active infection, or bleeding disorders, where PRP injections may not be appropriate<\/li>\n<\/ul>\n<h2>Before, During, and After Treatment: What to Expect<\/h2>\n<h3>Before Your First Appointment<\/h3>\n<p>Bring any records of previous hair loss treatment, including products, supplements, or medications you have used. If you have blood test results from your home country covering thyroid function, ferritin, or vitamin D levels, these can be useful starting points and may reduce the need for repeat testing.<\/p>\n<h3>During Consultation and Initial Treatment<\/h3>\n<p>A thorough consultation will include a scalp assessment and, where relevant, blood tests to exclude systemic causes. If medication is prescribed, it is typically dispensed at the clinic or via a linked pharmacy.<\/p>\n<p><strong>PRP or Stem cell supertanant injection<\/strong> \u00a0sessions involve a blood draw, approximately 20\u201330 minutes of centrifugation and scalp preparation, and then a series of fine injections across the treatment area. Topical anaesthetic cream or a local anaesthetic may be used to manage discomfort.<\/p>\n<h3>After Starting Treatment<\/h3>\n<p>A temporary phase of increased shedding (telogen effluvium) can occur in the first 4\u20138 weeks of starting minoxidil or some other treatments, which is a normal part of the follicular cycle shift and not a sign the treatment is failing. Visible improvement in hair density typically requires at least six months of consistent treatment, and results continue to develop over 12\u201324 months. Regular follow-up appointments allow the treating physician to assess response and adjust the approach if needed.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<dl class=\"kj-faq\">\n<dt>Q.

Your physician can provide documentation of the medications prescribed and the dosage, which you can share with a doctor in your home country. It is advisable to plan ahead if you know you will be travelling or relocating, as finasteride and dutasteride are available by prescription in most countries.<\/dd>\n<dd><\/dd>\n<dt>Q. How many PRP sessions will I need, and how far apart should they be?<\/dt>\n<dd>Most clinical protocols recommend an initial course of three to six sessions, typically spaced four to six weeks apart, followed by maintenance sessions every three to six months. The exact protocol is tailored to the individual based on the degree of hair loss and response to initial treatment.<\/dd>\n<dd><\/dd>\n<dt>Q. Is AGA treatment covered by Japanese national health insurance (kokumin kenko hoken)?<\/dt>\n<dd>AGA treatment is classified as cosmetic in Japan and is therefore not covered by the national health insurance system. All costs are borne directly by the patient. This applies whether you are enrolled in Japanese national health insurance, an employer-sponsored scheme, or an international private insurance plan \u2014 it is worth checking your individual policy for cosmetic exclusions before your appointment.<\/dd>\n<dd><\/dd>\n<dt>Q. Can women be treated for hair loss at the clinic?<\/dt>\n<dd>Yes. Female-pattern hair loss is assessed and managed at Kojimachi Dermatology &amp; Plastic Surgery Clinic. The treatment approach for women differs from men \u2014 finasteride and dutasteride are generally not appropriate for premenopausal women, but minoxidil, PRP\/Stem cell , and nutritional support can be considered. A full consultation and blood screening are recommended to confirm the diagnosis and identify any contributing systemic factors.<\/dd>\n<\/dl>\n<div class=\"kjmc-en-booking-inline\" style=\"background: #f7fbf7; border: 1px solid #d5e6d8; border-radius: 10px; padding: 16px 20px; margin: 26px 0; text-align: center;\">\n<p style=\"margin: 0 0 12px; color: #1a3a1f; font-size: 0.95em; line-height: 1.65;\"><strong>Have a question about this treatment?<\/strong><br \/>\nMessage us on LINE or WhatsApp \u2014 our English-speaking team usually replies the same day.<\/p>\n<p style=\"margin: 0; line-height: 1;\"><a style=\"display: inline-flex; align-items: center; gap: 8px; background: #06C755; color: #fff; padding: 10px 20px; border-radius: 8px; text-decoration: none; font-weight: bold; font-size: 0.92em; margin: 4px 6px; white-space: nowrap; vertical-align: middle;\" href=\"https:\/\/line.me\/R\/ti\/p\/@710uitns?ts=05311801&amp;oat_content=url#~\" target=\"_blank\" rel=\"noopener noreferrer\">Book via LINE<\/a><br \/>\n<a style=\"display: inline-flex; align-items: center; gap: 8px; background: #25D366; color: #fff; padding: 10px 20px; border-radius: 8px; text-decoration: none; font-weight: bold; font-size: 0.92em; margin: 4px 6px; white-space: nowrap; vertical-align: middle;\" href=\"https:\/\/whatsapp.com\/channel\/0029VbCA1v85K3zY4MLX2a1h\" target=\"_blank\" rel=\"noopener noreferrer\">Message on WhatsApp<\/a><\/p>\n<\/div>\n<h2>Summary<\/h2>\n<p>Androgenetic alopecia is a common and genuinely treatable condition, provided it is diagnosed accurately and addressed with evidence-based interventions at an appropriate stage.<\/p>\n<p>In Tokyo, <strong>English-speaking patients<\/strong> have access to the full range of AGA treatment options \u2014 from oral DHT-blocking medications to PRP injections and supportive nutritional therapy.
