In short
Injected minoxidil applies the drug directly into the scalp with micro-injections to stimulate hair growth. A 30–45 minute session with no downtime, with effects lasting 3–6 months. Price: €90 per session. Treatment is performed by Dr. Rubén Bermejo Pérez, a registered aesthetic physician (COMB no. 63226), at Clínica Sagrada Família, Barcelona.
Dr. Bermejo explains how minoxidil mesotherapy works and why it works best with consistency and in combination.
Medical judgement
“Topical minoxidil gets where it can. Injected minoxidil gets exactly where it needs to — the follicle — at the concentration it needs to work.”Dr. Rubén Bermejo Pérez
How it works · Injected minoxidil
More blood flow, a more active follicle.
Minoxidil widens the small vessels of the scalp.
It receives more blood and nutrients.
It works best when continued and combined.
What it treats
Injected minoxidil acts as a vasodilator — it improves blood supply to the follicle and extends its growth phase. In androgenetic alopecia it complements dutasteride's DHT blocking by providing the vascular stimulus the follicle needs to regain activity. One of the combined treatments with the most evidence for this indication.
Topical minoxidil needs daily application and its absorption through the scalp is variable. Many patients don't tolerate the topical form because of irritation, contact dermatitis or facial hair growth. Injection removes these problems — it's applied monthly or every two months at a much higher local concentration.
Injected minoxidil is often combined with hair PRP and injected dutasteride in the same protocol. Each works differently — minoxidil dilates vessels, PRP stimulates with growth factors and dutasteride blocks DHT. The combined protocol is the most effective option available for androgenetic alopecia.
Diffuse shedding from stress, hormonal changes or nutritional causes also responds to injected minoxidil. Here, follicle vasodilation slows active shedding and improves the quality of existing hair while the underlying cause is addressed. It's usually combined with hair mesotherapy in this context.

At Clínica Sagrada Família, C/ Torras i Pujalt 1 (3rd floor), Barcelona. It is performed personally by Dr. Rubén Bermejo Pérez, registered physician no. 63226.
Topical minoxidil is applied daily to the scalp and its absorption varies — depending on skin condition, the amount applied and washing. Injected minoxidil goes directly into the dermis of the scalp once a month — the local concentration is much higher and consistency is guaranteed without relying on a daily routine.
Minoxidil is a vasodilator — it opens potassium channels in vascular smooth muscle, improving blood supply to the follicle. A better-supplied follicle receives more oxygen and nutrients, extends its growth phase and produces thicker, stronger hair. It doesn't act on DHT — that's why it's combined with dutasteride.
Injection significantly reduces the systemic side effects of oral minoxidil — low blood pressure, fluid retention, excess hair growth. Systemic absorption is minimal. Possible local effects are mild tenderness or redness at the injection points for the first few hours.
Reduced shedding starts to show between the second and third month. Better density and thickness of existing hair show from the fourth month. The full result is assessed 6 months after starting.
Yes — it's the most complete combination available today. Minoxidil dilates the follicle's vessels, PRP stimulates it with growth factors and dutasteride blocks the DHT that destroys it. The three work through completely different mechanisms and reinforce each other. They can be given in the same session or alternate sessions.
Not necessarily. Injection can fully replace topical use — one of its main advantages for patients who don't tolerate the topical form or prefer not to depend on daily application. If you already use it, we'll decide at the consultation whether to combine both routes or replace one with the other.
Don't wash your hair for the first 6–8 hours. Avoid intense exercise and direct sun on the scalp for the rest of the day. Don't apply topical minoxidil on the day of treatment. Otherwise, normal life straight away.
