Precision
Health Canada approved scalp microneedling device. Sealed single-use sterile cartridge eliminates cross-contamination risk. Calibrated needle depth targets the follicular zone in the scalp for optimal exosome delivery.
Exosome Serum
Clinical-grade exosome serum derived from stem cells. Carries hundreds of growth factors, proteins, and signalling molecules that communicate directly with hair follicle cells — triggering repair, regeneration, and activity at the follicular level.
Retail Serum
The clinical-grade Exo-Grow serum is 1600x more potent than the retail at-home version. At-home serums sit on the surface with limited penetration. Microneedling delivers clinical serum directly into the follicular zone — a concentration and delivery mechanism that topical application cannot replicate.
Not a serum.
A clinical protocol.
The Exo-Grow clinical serum is 1600x more potent than the retail at-home version. If you have used serums at home without meaningful results, concentration is almost certainly part of the explanation — and clinical delivery via SkinPen addresses it directly.
Topical products cannot reliably penetrate the scalp to the follicular level. SkinPen microneedling creates precise channels in the scalp that deliver the Exo-Grow serum directly to dormant and miniaturised follicles — the ones that need to be reached.
Scalp microneedling stimulates a wound-healing response — triggering the scalp’s own growth factors, increasing blood flow, and activating stem cells in the follicle bulge — at the same time as delivering the Exo-Grow serum. Both happen in a single session.
Exo-Grow produces comparable outcomes to PRP (Platelet-Rich Plasma) for most presentations — without the blood draw, without the variable platelet concentration, and without the injection discomfort. A more consistent, lower-barrier protocol with strong clinical rationale.
Most hair loss research skews male. Exo-Grow works on the underlying mechanisms of female hair thinning — androgenetic alopecia, hormonal fluctuations, post-partum shedding, diffuse thinning — with the same clinical mechanism but applied to presentations that disproportionately affect women.
Non-surgical, no needles into the scalp (microneedling uses surface-level channels, not injection), no blood draw. Most clients return to normal activity the same day. Mild scalp redness and tenderness for 24–48 hours is typical and expected — nothing more.
Most people who come to Tight Clinic for Exo-Grow have already tried the at-home version. Some have tried it for months. The reason it did not deliver what the clinical treatment does comes down to one thing: concentration.
At-home serums are formulated for unsupervised topical use — the concentration is kept lower by design. The clinical-grade Exo-Grow used at Tight Clinic is 1600x more concentrated, and it is delivered directly into the scalp via SkinPen microneedling — bypassing the skin barrier entirely and reaching the follicular zone that topical application does not reach.
You've tried the serum.
This is different.
The comparison is not just concentration — it is the delivery mechanism. The SkinPen creates precise microchannels in the scalp that act as direct pathways to the follicle. The clinical exosome serum travels those channels to reach dormant and miniaturised follicles at the depth that matters.
The result is a fundamentally different clinical outcome from anything achievable at home — regardless of how consistently or correctly the retail product is applied.The comparison is not just concentration — it is the delivery mechanism.

to the scalp.
A thorough review of your hair loss history, health background, and goals. Your practitioner assesses the presentation and recommends the appropriate protocol — vial size, session frequency, and any complementary approaches.
Topical numbing cream is applied to the scalp and left for 30–45 minutes. Most clients use this time to relax — the procedure is well-tolerated with numbing applied.
SkinPen is used across the treatment area to create precise microchannels in the scalp at calibrated depth. Mild pressure or light scratching sensation is typical.
The clinical-grade Exo-Grow exosome serum is applied into the microchannels, penetrating directly to the follicular zone. The 1600x clinical concentration works from inside the scalp, not on the surface.
Avoid washing, products, and heavy sweating for 24 hours. Mild redness and scalp sensitivity resolves in 24–48 hours. Results accumulate over 2–3 months per session through the natural hair growth cycle.

SkinPen Precision is a Health Canada approved microneedling device used in medical aesthetics clinics. Its sealed, single-use sterile cartridge system eliminates cross-contamination risk and ensures consistent needle depth calibration — particularly important for scalp treatment where precise follicular depth targeting matters.
Exosomes are extracellular vesicles produced by cells for intercellular communication — they carry growth factors, proteins, and signalling molecules that instruct recipient cells to repair, regenerate, and activate. In the context of hair follicles, exosomes can reawaken dormant follicles, improve the scalp microenvironment, and promote the transition from resting to active growth phase.
Tight Clinic is a Toronto-founded medical aesthetics clinic with two locations, 30 staff, and 500+ Google reviews at 4.9 stars. Exo-Grow scalp microneedling is performed by experienced aestheticians and nurses within a full medical aesthetics environment — not a hair salon or spa setting.

Results our clients
can see.
“I’d been using Exo-Grow at home for six months with minimal results. After three clinical sessions at Tight Clinic my parting has visibly filled in and I’m shedding significantly less. The explanation about the 1600x concentration difference finally made sense of why the home version didn’t work — it’s not the same product. Genuinely impressed.”
“I was considering PRP but was not keen on the blood draw. The team at Tight Clinic explained how Exo-Grow compares — the standardised concentration, no blood draw, the SkinPen delivery getting it to the follicle directly. Two sessions in and the density at my temples has improved noticeably. I’ll be doing the full series.”
“Post-partum hair loss that started nine months ago. I’d tried every supplement and serum recommended — nothing substantial. Three Exo-Grow sessions in and I’m seeing significant regrowth along the hairline. The numbing makes it completely comfortable. Tight Clinic is professional and the results speak for themselves.”
Every question about
Exo-Grow, answered.
15 questions covering the science, the 1600x difference, PRP comparison, candidates, results, downtime, and pricing — answered directly.
Exosome hair treatment uses cell-signalling vesicles (exosomes) derived from stem cells to reawaken dormant hair follicles and stimulate new growth. Exosomes carry growth factors, proteins, and signalling molecules that communicate directly with follicular cells — triggering the repair, regeneration, and activity that hair follicles need to produce thicker, denser hair. Exo-Grow at Tight Clinic uses clinical-grade exosomes delivered into the scalp via SkinPen microneedling, combining two well-established mechanisms for maximum follicular penetration and activation.
The difference is concentration — and it is substantial. The clinical-grade Exo-Grow serum used at Tight Clinic is 1600x more potent than the retail at-home version. At-home serums are formulated for topical application, where penetration through the scalp is limited and active concentration is deliberately kept lower for unsupervised use. The clinical serum is delivered directly into the scalp via SkinPen microneedling — bypassing the skin barrier entirely and reaching the follicular level at a concentration that retail application cannot replicate. If you have used an at-home serum without the results you expected, this is why.
Both PRP (Platelet-Rich Plasma) and Exo-Grow target hair follicle stimulation, but they work differently. PRP involves drawing your own blood, processing it, and re-injecting the platelet-rich portion into the scalp — a more involved process with a blood draw, variable growth factor concentration depending on your own platelet levels, and injection discomfort. Exo-Grow delivers a standardised, clinically concentrated exosome serum via SkinPen microneedling — no blood draw, consistent potency every session, and gentler delivery than injection. For many clients, Exo-Grow is a compelling, lower-barrier alternative to PRP with comparable or superior outcomes.
Exo-Grow and PRP are both clinically validated approaches to hair restoration. Exo-Grow has several practical advantages over PRP: no blood draw is required, the exosome concentration is standardised and consistent across every session (PRP potency varies by individual), and microneedling delivery is gentler than scalp injections. For clients who want non-surgical hair restoration without the clinical complexity of PRP, Exo-Grow at Tight Clinic is a strong and increasingly preferred option. At your consultation, the team can advise whether Exo-Grow, PRP, or a combination approach is most appropriate for your presentation.
Exo-Grow is suitable for most adults experiencing hair thinning, reduced hair density, or early-to-moderate hair loss. This includes androgenetic alopecia (the most common form of hair loss in both men and women), diffuse thinning, post-partum hair loss, stress-related shedding, and hair thinning associated with hormonal changes including perimenopause and menopause. Results are strongest when treatment begins before significant follicular miniaturisation has occurred — earlier intervention typically produces more complete outcomes. A consultation with the Tight Clinic team will confirm whether Exo-Grow is appropriate for your specific presentation.
Yes — Exo-Grow is particularly well-suited to female hair loss and hair thinning in women. Most hair restoration content and clinical trials have historically focused on male pattern baldness, but female hair loss is common — affecting around 40% of women by age 50 — and often inadequately addressed. The mechanisms driving female hair thinning (androgenetic alopecia, hormonal fluctuations, diffuse thinning across the crown and parting) respond well to exosome therapy and scalp microneedling. At Tight Clinic, the team has specific experience treating hair thinning in women, including thinning related to perimenopause and menopause.
Female hair thinning has several common drivers: androgenetic alopecia (genetically-driven follicular sensitivity to DHT), hormonal shifts (fluctuating oestrogen and progesterone during perimenopause, menopause, post-partum, or thyroid conditions), chronic stress and elevated cortisol (which pushes follicles prematurely into the resting phase), nutritional deficiencies (particularly iron, ferritin, and zinc), and traction or styling damage over time. Exo-Grow addresses the follicular side — reactivating miniaturised or dormant follicles and improving the scalp environment for growth — but a thorough consultation will consider the underlying drivers and whether additional support (such as bloodwork with a GP or naturopathic care) is warranted alongside treatment.
Yes — and combination approaches often produce the best outcomes. Exo-Grow scalp microneedling pairs well with topical minoxidil (applied after the microneedling channels close, typically 24–48 hours post-treatment), oral or topical finasteride/dutasteride where appropriate, nutritional supplementation targeted to identified deficiencies, and lifestyle or hormonal support. At Tight Clinic, clients who see Dr. Liz Rychlik (N.D.) alongside their Exo-Grow treatments can address the systemic contributors — hormonal balance, stress, and nutritional status — while the clinical exosome treatment works at the follicular level.
Scalp microneedling works on two mechanisms simultaneously. First, the microchannels created by the SkinPen needles trigger a wound-healing response — the scalp produces growth factors, increases blood flow to the follicular area, and stimulates stem cells in the hair follicle bulge. Second, the microchannels act as direct delivery pathways for the Exo-Grow serum — allowing the clinical-grade exosomes to penetrate the scalp at the follicular level rather than sitting on the surface. The combination of mechanical stimulation and targeted exosome delivery is what makes Exo-Grow scalp microneedling significantly more effective than topical application alone.
For Exo-Grow scalp microneedling, a series of 3–4 sessions spaced 4–6 weeks apart is the standard protocol for most presentations. Hair growth cycles mean that results accumulate over time — you are not just treating the active follicles but stimulating dormant ones through multiple growth cycles. Maintenance sessions every 3–6 months are recommended following the initial series to sustain and build on results. Your Tight Clinic practitioner will assess your specific presentation at consultation and provide a personalised protocol.
Scalp microneedling with SkinPen is generally well-tolerated. A topical numbing cream is applied before the treatment and left on for 30–45 minutes, significantly reducing sensation. Most clients describe mild pressure or a light scratching sensation during the procedure rather than pain. The scalp is more sensitive than facial skin in some areas — around the hairline and temples — but the numbing cream typically manages this effectively. Post-treatment, you may experience mild tenderness and redness for 24–48 hours, similar to a mild sunburn sensation.
A full Exo-Grow scalp microneedling session takes approximately 60–75 minutes including numbing time (30–45 min) and the treatment itself (20–30 min). There is no formal downtime — most clients return to their regular activities the same day. Avoid washing the scalp, sweating heavily, or applying products for 24 hours post-treatment. Redness and mild scalp sensitivity typically resolve within 24–48 hours. The full series of 3–4 sessions is typically completed over a 3–4 month period.
Hair growth follows biological cycles, which means results develop gradually. Most clients notice reduced shedding within 4–6 weeks of the first session, with new growth and improved hair density typically visible at 2–3 months. The most significant improvements generally appear at 3–6 months — after the full initial series is complete and through one or two complete hair growth cycles. Individual results vary based on the cause and extent of hair loss, age, and consistency of treatment. Before-and-after photos are taken at Tight Clinic to track progress objectively over the course of treatment.
Yes — Exo-Grow scalp microneedling is a well-tolerated, non-surgical procedure with a strong safety profile. The SkinPen device is Health Canada approved, and the Exo-Grow exosome serum is a clinical-grade formulation used in medical aesthetics internationally. Side effects are typically limited to mild redness, scalp tenderness, and minor swelling that resolves within 24–72 hours. The treatment is not recommended during pregnancy, in clients with active scalp infections or inflammatory conditions, or in those with certain autoimmune conditions — your Tight Clinic practitioner will review this at consultation.
At Tight Clinic, Exo-Grow hair microneedling is priced as follows: Microneedling with Exo-Grow (0.5 Vial) — $675 and Microneedling with Exo-Grow (1 Vial) — $800. The 1-vial option is the recommended protocol for most presentations — it delivers a higher exosome concentration per session and typically produces stronger results. A series of 3–4 sessions is standard; maintenance sessions are recommended every 3–6 months thereafter. Pricing at other Toronto clinics varies widely — the clinical-grade Exo-Grow serum used at Tight Clinic is 1600x more potent than retail formulations.
