In short
Hair biostimulation applies regenerative actives to the scalp to slow hair loss and strengthen the hair. Sessions of 30–45 minutes with no downtime, with effects lasting 9–12 months. Price: from €55 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 hair biostimulation improves the follicle and its environment, as a complement to other treatments.
Medical judgement
“Hair biostimulation doesn't add or replace. It activates what the follicle already knows how to do — grow — and gives it the conditions to do it better.”Dr. Rubén Bermejo Pérez
How it works · Hair biostimulation
Improving the follicle's environment.
Applied with micro-injections into the scalp.
The vessels and fibres that surround and nourish the follicle.
Usually alongside other treatments.
What it treats
Hair biostimulators — polynucleotides, PDRN and similar — activate scalp fibroblasts and improve the follicle's micro-environment. The result is thicker, stronger hair with a longer growth cycle. The ideal regenerative complement for early androgenetic alopecia or fine hair lacking density.
Hair biostimulation significantly improves the quality of existing hair — thickness, shine, elasticity and resistance to breakage. For people without alopecia who notice their hair has lost density and vitality, it's the most suitable treatment without a full medical protocol.
Hair biostimulation is the ideal regenerative complement to PRP and injected dutasteride. While PRP stimulates with your own growth factors and dutasteride blocks DHT, the biostimulator improves the scalp tissue that surrounds and nourishes the follicle. The combined protocol is more effective than any single treatment.
A scalp damaged by excessive dyeing, chemical treatments, heat or mechanical stress loses the micro-environment hair needs to grow. Biostimulation repairs and regenerates it — improving circulation, scalp hydration and follicle response.
The practical side
Everything you need to know before your consultation. No small print.
Longer-lasting than hair mesotherapy. With maintenance sessions the result holds and builds up.
Including anaesthetic and micro-injections. Initial protocol of 3–4 sessions, 3–4 weeks apart.
Possible mild tenderness or redness of the scalp for the first few hours. Normal life straight away.
It depends on the type of biostimulator and the session protocol. It is set at the assessment.
The hair cycle
Growth, transition and rest.
The growth phase: it lasts years.
A brief transition in which the follicle shrinks.
Rest: the hair falls and a new one starts.

The guide price starts at €55 per session. It depends on the type of biostimulator and the session protocol, and is set at the assessment. The first consultation is free. You can see all fees on the prices page.
Usually 9–12 months — longer than hair mesotherapy. With maintenance sessions the result holds and builds up.
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.
Hair biostimulation uses injectables — usually polynucleotides or PDRN — that activate scalp fibroblasts and improve the follicle's micro-environment. Unlike PRP, which uses growth factors from your own blood, biostimulators are standardised external products that act on the scalp's cell regeneration mechanisms.
PRP uses your own growth factors — from your blood — and needs a blood draw and centrifugation. Biostimulation uses standardised external products acting on the scalp's cellular micro-environment. They complement each other — PRP stimulates the follicle and biostimulation improves the environment it has to work in.
The improvement starts to show from the second or third session — less shedding, thicker and shinier hair. The full result is assessed 3–6 months after starting. Like all regenerative hair treatments, the effect is gradual and builds with each session.
We use local anaesthetic or mechanical vibration to minimise discomfort. The scalp is sensitive but most patients tolerate it well. The main discomfort is the anaesthetic prick — the rest is well tolerated.
The usual initial protocol is 3–4 sessions, 3–4 weeks apart, then maintenance sessions every 4–6 months. Consistency is especially important in hair treatment — the follicle needs continued stimulus to stay active.
Yes — it's the most effective combination. Biostimulation improves the follicle's micro-environment, PRP stimulates the follicle with growth factors and dutasteride blocks the DHT that destroys it. Each works at a different level — together they cover every front of hair treatment.
Don't wash your hair for the first 6–8 hours. Avoid intense exercise, heat and direct sun on the scalp for the rest of the day. Don't apply irritating products to the scalp for the first 24 hours. Otherwise, normal life straight away.
