AGA is the condition; finasteride, dutasteride and minoxidil are the drugs used against it. The real question most readers are asking is: <em>are there alternatives to the standard drugs?<\/em><\/p>\n<p>In Japan, that question has a practical edge. The Japanese Dermatological Association notes on its public Q&amp;A that because male-pattern hair loss is interpreted as a form of age-related change rather than a disease, most effective treatments cannot be received under health insurance \u2014 they are self-pay (\u81ea\u7531\u8a3a\u7642).<\/p>\n<p>At BIOTOPE CLINIC in Shirokanedai, we frequently see patients who have already read about these medicines online and want to understand what else exists before starting, or who have concerns about taking a hormone-pathway drug long term.<\/p>\n<h2>What the Standard Medicines Do \u2014 and What They Do Not Do<\/h2>\n<figure style=\"margin: 1.5em 0;\"><img decoding=\"async\" style=\"width: 100%; max-width: 100%; height: auto; border-radius: 8px;\" title=\"AGA vs finasteride and minoxidil: regenerative alt \u2014 What the Standard Medicines Do \u2014 and What They Do Not Do\" src=\"https:\/\/kojihifu.com\/english\/wp-content\/uploads\/2026\/08\/pexels_28994390_1787441533.webp\" alt=\"AGA vs finasteride and minoxidil: regenerative alt \u2014 What the Standard Medicines Do \u2014 and What They Do Not Do\" \/><\/figure>\n<h3>Finasteride and dutasteride (oral 5-alpha-reductase inhibitors)<\/h3>\n<p>These tablets block the enzyme that converts testosterone into dihydrotestosterone (DHT), the androgen that gradually miniaturises genetically susceptible hair follicles. They address the driver of AGA rather than stimulating hair directly.<\/p>\n<p>The Japanese package insert for Propecia (finasteride) reports a domestic 48-week double-blind study in 414 Japanese men aged 24\u201350, in which photographic assessment rated 58.3% improved on 1 mg and 54.2% on 0.2 mg, versus 5.9% on placebo. Sexual dysfunction \u2014 chiefly reduced libido and erectile difficulty \u2014 was reported in 2.9% (1 mg) and 1.5% (0.2 mg), and the insert notes post-marketing reports of symptoms persisting after discontinuation.<\/p>\n<p>Dutasteride, approved in Japan in 2015 as the country&#8217;s second oral drug for male-pattern hair loss, inhibits both type 1 and type 2 forms of the enzyme. Importantly, the 2017 Japanese guidelines state that oral finasteride and dutasteride are <strong>contraindicated<\/strong> for female-pattern hair loss.<\/p>\n<h3>Topical minoxidil<\/h3>\n<p>Minoxidil applied to the scalp works through a different mechanism \u2014 it prolongs the growth (anagen) phase and improves follicular blood supply. In Japan, 5% minoxidil is sold as an over-the-counter Class 1 medicine, supplied with a pharmacist&#8217;s explanation rather than a prescription.<\/p>\n<p>The 2017 Japanese Dermatological Association guidelines list finasteride 1 mg daily, dutasteride 0.5 mg daily and topical 5% minoxidil twice daily as <strong>first-line<\/strong> treatments for male-pattern hair loss, and topical 1% minoxidil twice daily for female-pattern hair loss.<\/p>\n<h3>Oral minoxidil \u2014 a common misunderstanding<\/h3>\n<p><strong>Oral minoxidil<\/strong> tablets are frequently marketed online as a &#8220;stronger&#8221; version. They are not approved in Japan for hair loss, and the 2017 Japanese guidelines state plainly that oral administration of minoxidil <strong>should not be performed<\/strong>. The same guidelines also advise against artificial (prosthetic) hair implantation.<\/p>\n<h2>Regenerative Alternatives Offered 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=\"AGA vs finasteride and minoxidil: regenerative alt \u2014 Regenerative Alternatives Offered in Tokyo\" src=\"https:\/\/kojihifu.com\/english\/wp-content\/uploads\/2026\/08\/pexels_23349891_1787441533.webp\" alt=\"AGA vs finasteride and minoxidil: regenerative alt \u2014 Regenerative Alternatives Offered in Tokyo\" \/><\/figure>\n<h3>PRP (platelet-rich plasma)<\/h3>\n<p>PRP uses a small volume of your own blood, spun in a centrifuge to concentrate platelets, which is then injected into the scalp to deliver growth factors around the follicles. Sessions are typically spaced over several months, with results assessed over half a year or more.<\/p>\n<p>The evidence is genuinely mixed. A 2024 systematic review and meta-analysis of 13 randomised trials (431 participants) reported a mean difference of 27.55 hairs\/cm\u00b2 (95% CI 14.04\u201341.06) favouring PRP over placebo, but the authors classed this as low-quality evidence with high heterogeneity (I\u00b2 \u2248 96%) and evident publication bias. A larger 2025 meta-analysis of 43 randomised trials (1,877 participants) concluded that moderate evidence supports PRP for improving hair density and reducing hair loss, while finding no significant effect on hair thickness.<\/p>\n<p>In Japan, autologous PRP for hair is regulated: clinics must file a regenerative medicine provision plan with the health authorities before providing it, and providing such treatment without a filed plan carries penalties under the Act on the Safety of Regenerative Medicine. Plans for hair-growth PRP appear in the Ministry of Health, Labour and Welfare&#8217;s public database \u2014 a useful thing for patients to ask about.<\/p>\n<h3>Stem-cell culture supernatant and &#8220;exosome&#8221; therapies<\/h3>\n<p>These treatments inject the liquid fraction left after culturing stem cells, which contains secreted factors and extracellular vesicles (often marketed as exosomes), into the scalp. This is the fastest-growing category in Tokyo \u2014 and the one where regulatory literacy matters most.<\/p>\n<p>An administrative notice issued by the Ministry of Health, Labour and Welfare on 31 July 2024 stated that no medicine using stem-cell culture supernatant or the exosomes it may contain has demonstrated efficacy and safety and obtained marketing approval, in Japan or abroad. Because these preparations contain no cells, they currently fall <em>outside<\/em> the scope of the Act on the Safety of Regenerative Medicine, and the ministry asked providers to follow the Japanese Society for Regenerative Medicine&#8217;s guidance on extracellular vesicles. Related notices instructed authorities to crack down on &#8220;exosome reagents&#8221; advertised with medicinal claims as unapproved, unlicensed drugs.<\/p>\n<p>Scalp injection of stem-cell culture supernatant is a treatment available within our clinic group at BIOTOPE CLINIC in Shirokanedai \u2014 feel free to ask about its current evidence base and limitations during a consultation with Dr. Karibe.<\/p>\n<h3>Hair transplantation<\/h3>\n<p>Autologous hair transplantation \u2014 moving DHT-resistant follicles from the back of the scalp \u2014 is recommended in the 2017 Japanese guidelines. It is surgical, involves real recovery time, and is generally considered once medical treatment has stabilised shedding.<\/p>\n<table style=\"border-collapse: collapse; width: 100%; margin: 20px 0; font-size: 0.95em;

The 2017 Japanese Dermatological Association guidelines name finasteride, dutasteride and topical minoxidil as first-line therapy; hair-regeneration approaches were reviewed as emerging treatments, not substitutes. In practice, regenerative options are usually discussed as an addition for people already on \u2014 or unable to take \u2014 the standard drugs.<\/p>\n<p><strong>&#8220;Exosome therapy is government-approved regenerative medicine.&#8221;<\/strong> It is not. The ministry&#8217;s July 2024 notice is explicit that no such product holds marketing approval, and because these preparations are cell-free they sit outside the Act that governs regenerative medicine.

Women should not take finasteride or dutasteride, and are generally managed with topical minoxidil at the concentration appropriate for female-pattern hair loss.<\/p>\n<p>Regenerative options are more reasonably considered by people who cannot tolerate or do not wish to take oral 5-alpha-reductase inhibitors, or who have plateaued on medication \u2014 provided they accept that the evidence is less mature. Anyone with sudden, patchy or scarring hair loss should be assessed first, because that pattern suggests a different diagnosis altogether.
