Hair Exosomes: A Complete Guide to Exosome Hair Restoration

How Exosomes Stimulate Hair Growth

A healthy hair follicle cycles through phases of active growth (anagen), transition (catagen) and rest (telogen). In androgenetic hair loss and other forms of thinning, more follicles become stuck in the telogen phase, producing progressively finer and shorter hairs until the follicle may miniaturise to the point where it is no longer visible. Exosomes aim to shift follicles out of this dormant state and back into active growth.

The AnteAGE MD exosomes used at Berkshire Aesthetics are derived from bone-marrow mesenchymal stem cells and purified so that only the vesicles themselves remain — there are no live cells in the finished product. The vesicles carry a rich payload of growth factors (including VEGF, FGF and PDGF), cytokines and microRNAs that signal to dermal papilla cells and hair matrix cells. The signalling supports follicle stem-cell activity, improves local microcirculation and reduces inflammatory signalling that drives miniaturisation.

Microneedling with SkinPen creates controlled micro-channels in the scalp. The channels serve two purposes: they allow the exosome solution to be delivered into the dermis where follicles live, and the controlled micro-injury itself triggers a wound-healing response that supports follicle activity. The combination of exosomes + microneedling is more effective than either treatment alone.

Exosomes vs PRP vs Minoxidil

Exosomes vs PRP

PRP (platelet-rich plasma) is prepared from a patient’s own blood and contains platelet-derived growth factors that also stimulate hair follicles. PRP has good evidence and is a reasonable lower-cost option. Exosomes contain a broader, more concentrated set of signalling molecules and do not require a blood draw, which makes them more comfortable and easier to standardise. Clinical reports suggest exosomes produce more robust regrowth in many patients, particularly those who did not respond fully to PRP.

Exosomes vs minoxidil

Minoxidil is a topical medication (available as 2% or 5% solution or foam, or as low-dose oral minoxidil on prescription) that extends the anagen growth phase. It works well for many patients but requires indefinite daily use — stop using it and the benefit is gradually lost. Exosomes are a course-based treatment with periodic maintenance. The two approaches are complementary: many patients continue minoxidil while adding exosome sessions for a stronger overall response.

Exosomes vs finasteride

Finasteride (or dutasteride) is a prescription anti-androgen that addresses the hormonal driver of male-pattern hair loss. It is highly effective for many men but is a systemic medication with potential side effects and is not appropriate for female patients in reproductive years. Exosomes work through a different mechanism and can be combined with finasteride for patients already taking it.

Hair Exosome FAQs

What are hair exosomes?

Exosomes are tiny extracellular vesicles that cells use to send signalling molecules to other cells. In hair restoration, purified exosomes derived from bone-marrow mesenchymal stem cells carry growth factors and microRNAs that signal to dormant hair follicles to re-enter an active growth phase. At Berkshire Aesthetics we use AnteAGE MD exosomes delivered via SkinPen microneedling channels, which allows the exosomes to reach the follicles directly.

Do hair exosomes actually work?

Clinical studies and real-world reports show meaningful improvement in hair density, thickness and visible scalp coverage for many patients with early-to-moderate thinning, particularly androgenetic hair loss and telogen effluvium. Exosomes do not create new follicles where there are none — they stimulate existing dormant follicles. Patients with fully scarred or completely lost follicles are not suitable. Response is individual and a consultation assesses likely benefit.

Are exosomes better than PRP for hair loss?

Exosomes and PRP both aim to stimulate dormant hair follicles, but they use different signalling mechanisms. Exosomes contain a broader and more concentrated set of growth factors and microRNAs than PRP and do not require a blood draw. Clinical reports suggest exosomes may produce more robust regrowth, particularly in patients who did not respond well to PRP. PRP remains a valid, lower-cost option; exosomes are often chosen where greater regenerative signalling is wanted or where PRP has not produced sufficient results.

How many hair exosome sessions do I need?

Most patients have a course of 3 sessions spaced 4–6 weeks apart. Some patients with more advanced thinning benefit from a 4-session course. Follow-up maintenance is typically one session every 6–12 months to sustain the response.

When will I see results from hair exosomes?

Early signs of reduced shedding and softer new-growth hairs are often noticed within 4–6 weeks of the first session. Visible density improvement typically develops over 3–6 months. Full effect of a course is assessed at around 6 months after the final session. Progress is monitored with clinical photography at each review.

Does the hair exosome treatment hurt?

Topical anaesthetic is applied before SkinPen microneedling to minimise discomfort. Most patients describe the sensation as mild scratching or pressure rather than sharp pain. Scalp microneedling is generally well-tolerated. Some mild redness and tenderness can persist for 24–48 hours.

What is the downtime after hair exosomes?

There is essentially no social downtime. Scalp redness and mild tenderness settle within 24 hours. Hair should not be washed for 12 hours after treatment; harsh shampoos, heat styling, sauna and swimming should be avoided for 48 hours.

How much do hair exosomes cost?

At Berkshire Aesthetics, hair exosome sessions are priced from £350 per session, with a course of three typically costing £900–£1,200. Pricing is confirmed at consultation after scalp assessment.

Can women have exosome hair treatment?

Yes. Exosome hair restoration is appropriate for both women and men. Common female indications include female-pattern thinning (particularly at the crown and parting), post-partum telogen effluvium, and stress-related diffuse shedding. Suitability is assessed at consultation and underlying medical causes of hair loss are considered before treatment.

Are hair exosomes safe?

Exosome products used in UK medical aesthetics are regulated as cosmetic products and purified to remove cellular material. Delivered by a trained clinician in a CQC-registered setting using sterile technique, treatment has a strong safety record. Common side effects are temporary redness and tenderness. Rare complications include infection or inflammatory reaction, which require clinical review.
