Hair Mesotherapy (Injectable Minoxidil & Dutasteride)

Hair mesotherapy at Wall Street Dermatology delivers injectable minoxidil and injectable dutasteride directly into the scalp via microinjections to address androgenetic alopecia and hair thinning. This targeted delivery bypasses systemic absorption, concentrating the active agents at the hair follicle level. Sessions run 30–60 minutes. Visible hair density improvement is associated with appearing after 3–6 months of monthly sessions.

Wall Street Dermatology offers hair mesotherapy as their primary approach to androgenetic alopecia and hair thinning — distinct from PRP (platelet-rich plasma), which the clinic does not offer. Hair mesotherapy involves the microinjection of pharmaceutical agents directly into the scalp dermis at the level of the dermal papilla and hair follicle bulge, using a fine-gauge needle or mesotherapy gun to deposit small droplets of solution across the thinning zone. The active agents used at the clinic are injectable minoxidil and injectable dutasteride. Minoxidil, a potassium channel opener and vasodilator, is well-established as a topical hair regrowth agent; in injectable form, it bypasses the variable skin penetration of topical formulations and achieves direct follicular delivery at controlled concentrations. Dutasteride is a Type I and Type II 5-alpha reductase inhibitor that blocks the conversion of testosterone to dihydrotestosterone (DHT) — the primary androgen responsible for progressive follicle miniaturisation in androgenetic alopecia. Injectable dutasteride delivered intradermally creates a locally concentrated DHT-inhibitory environment around the follicles with substantially lower systemic exposure compared to oral dutasteride, potentially reducing systemic androgenic side effects while maintaining local efficacy. The combination of a follicular vasodilator (minoxidil) and a DHT blocker (dutasteride) delivered directly to the scalp targets the two primary mechanisms of androgenetic alopecia simultaneously. Each session runs 30–60 minutes including scalp preparation and injection. A monthly session schedule is typically recommended, with visible improvement in hair density and thickness associated with appearing after 3–6 months of consistent treatment. Maintenance sessions sustain the improvement thereafter. Pricing is consultation-based.
