Finasteride and Minoxidil

Finasteride and Minoxidil have both received a ranking of A (indicating the most effective) on the hair loss treatment guidelines announced by the Japanese Dermatological Association.

Used alone, these drugs are very effective forms of AGA treatment. Combining them has been shown to achieve even greater synergistic effects.

We draw from numerous treatment studies to prepare a proprietary formulation of finasteride and Minoxidil, these two class A substances. Our custom-made AGA prescriptions also include supplements like zinc and vitamins that are effective in promoting hair growth.


Minoxidil acts directly on hair matrix cells to improve blood flow. Increasing blood flow transports more nutrients to hair follicles and promotes hair growth.

Used on its own, Minoxidil promotes growth of existing follicles, but it is not very effective at creating fine peach fuzz. Therefore, combining Minoxidil and finasteride is held to be the most effective means of promoting hair growth.

Minoxidil can be administered topically or ingested. While the topical formulation can be purchased at pharmacies, the internal medication is not prescribed at many standard medical facilities and is rather the domain of hair growth clinics.

Note that, in some cases, a patient may be unable to use Minoxidil.

These cases include:

  • Pheochromocytoma
  • Heart arrythmia or heart disease
  • Potential of renal failure through metabolic pathways

When using Minoxidil, always consult with a medical professional.

Minoxidil acts by dilating the blood vessels.

Therefore, it accumulates salt and water in the body, which can lead to heart failure in people with the above contraindications. Because it can also quicken the pulse, we use it in conjunction with beta blockers for their diuretic effect, and ability to reduce the pulse and blood pressure.

It is sometimes used in combination with supplements and other medication in order to reduce blood pressure. For these reasons, we craft a treatment plan only after performing blood tests, electrocardiograms (ECGs), and other diagnostics.

The consumable form of Minoxidil can be purchased by individuals. Not only can counterfeits not produce the desired effect, but self-medicating runs the risk of consuming the wrong amount, which is extremely dangerous and could even exacerbate hair loss.

Among the internal products we prescribe is genuine Minoxidil (it is not found in all of our prescriptions). We also prescribe a proprietary, custom-made blend of finasteride, minerals, and vitamins to maximize hair growth benefits.


Finasteride prevents the 5-alpha-reductase enzyme from acting on the male testosterone hormone and converting it to dihydrotestosterone (DHT).

Because DHT is one factor in hair loss through AGA, blocking the creation of DHT also prevents hair loss.

Finasteride is manufactured and sold in Japan under the “Propecia” name.

How does a custom made prescription work?

Our custom-made prescriptions revolve around Minoxidil and finasteride blended with other products. They are the current best solution to hair loss treatment.

The Japanese Dermatological Association has ranked these two substances as Class A, making them the most trusted solutions in terms of both effectivity and safety.

At Osaka AGA Kato clinic, we prescribe capsules with a proprietary blend of these two substances and other vitamins, zinc, contributes to hair growth, and other substances.

Features of our order-made medication regimen

  • Just 1 capsule per day
  • No need for topical creams
  • Some people see results as soon as 2-3 months
  • Safe, with very few side effects

Here is a sample of some of our past hair regrowth cases.

Male in his 40s

The hairline and entirety around the head had thin hair, making treatment a challenge. While this is an extreme case of alopecia, we used our proprietary treatment to achieve astonishing results.
Using hair transplant therapy for this condition would be prohibitively expensive due to the area needed. Recent advances in AGA treatment are what enabled this dramatic outcome.

AGA can be cured using proper medical treatment.

Thin hair can be cured with proper care at a clinic or hospital. The Osaka AGA Kato Clinic is dedicated specifically to the treatment of AGA.

There are still few clinics specializing in this area in Japan, and we have a wealth of experience. Because trained medical professionals in the hair and scalp perform treatment based on medical evidence, it is a world of difference from what you would find at beauty and hair salons that promote unscientific treatments.

Most patients experience hair growth within six months of treatment and are delighted at the results they see.

We encourage you to come for counseling before your hair loss or thinning progresses.
