What is capillary dutasteride?
Capillary dutasteride is an antiandrogenic drug used medically that, when applied to the scalp (capillary mesotherapy) or taken orally as prescribed by a doctor, slows hair loss in androgenetic alopecia by inhibiting the conversion of testosterone to DHT, the main cause of follicle miniaturization.
Medical evidence and support
Dutasteride is an antiandrogenic drug authorized by the Spanish Agency of Medicines and Medical Devices (AEMPS) for the treatment of prostatic hyperplasia and, off-label, for androgenetic alopecia. The Spanish Academy of Dermatology and Venereology (AEDV) and the Spanish Society of Aesthetic Medicine (SEME) recognize its use in capillary mesotherapy as a complement to oral treatments or as an alternative when these are not tolerated. Comparative studies show efficacy equivalent to or greater than oral finasteride.
What does the capillary dutasteride treatment consist of?
The treatment is carried out entirely in the medical office of the Instituto de Benito in Barcelona or Madrid, in an outpatient session always designed and supervised by a licensed aesthetic doctor. It consists of the following steps:
Personalized medical assessment:

The doctor evaluates the type and pattern of hair loss, rules out hormonal or nutritional causes, and, if appropriate, recommends a genetic test for androgenetic alopecia. First visit €50.
Treatment Preparation

The scalp should be clean. No gel, no hairspray, no styling products. The doctor selects the personalized cocktail suitable for your type of alopecia.
Application of treatment in consultation

The doctor performs microinjections on the scalp with a very fine needle, following the treatment pattern. The session is well tolerated.
Start looking the way you want to feel

Results are built session by session: first, hair loss is stopped, then density improves, and finally, hair thickness. The doctor plans the necessary periodic maintenance.

Is it forever?
Continuity is needed to maintain the result. If discontinued, hair loss may reappear.
Difference between topical dutasteride and oral finasteride?
Both are antiandrogenic. Finasteride: oral, inhibits the conversion of testosterone to DHT only through the type 2 5-alpha-reductase enzyme. Dutasteride: inhibits both enzymes (type 1 and 2), making it more potent. Topical application (mesotherapy) reduces systemic exposure compared to the oral route.
How soon are results seen?
Hair loss stops at 8-12 weeks. Improvement in density and thickness from the 3rd-6th month. The AEDV indicates that in androgenetic alopecia the treatment must be sustained: if discontinued, hair loss may reappear in the following 6-12 months.
Is it safe for women?
In women of childbearing age without adequate contraception, it is contraindicated due to teratogenic risk. In selected women (perimenopause, menopause, confirmed contraception), it can be prescribed with specific medical evaluation.

The combined pack has better documented results according to SEME, especially in moderate androgenetic alopecia.
Is the genetic test mandatory before starting?
No, but it is highly recommended, it rules out other causes of hair loss and allows for a more precise prognosis. SEME indicates that in doubtful cases the genetic test is the most reliable diagnostic tool.
