Exosomes for Hair Loss: 2026 Hype vs Evidence
Plausible biology, thin clinical data, premium pricing. The honest 2026 read on exosome therapy for hair loss and where it actually fits.
Philippe Boissard
Philippe Boissard, M.Sc., is a hair loss researcher and author. He breaks down the science of androgenetic alopecia and the treatments men actually weigh up, working from the primary literature rather than marketing claims. New here? Start with his guide to how hair loss actually works.
TRT and Hair Loss: How to Run Both Without Wrecking Your Hairline
TRT does not cause hair loss in non-predisposed men. It accelerates AGA in men who carry the predisposition. The trade-off is real, the management is well-defined, and the men who lose the most are the ones who treated the math as an afterthought.
PRP for Hair Loss: Protocol, Evidence, and Realistic Expectations
Platelet-rich plasma works in mild-to-moderate AGA when properly administered. Effect tier similar to topical minoxidil. Protocol variability drives outcome variability between clinics.
Low-Level Laser Therapy for Hair Loss: What the Evidence Actually Shows
Low-level laser therapy produces real but modest hair count gains in randomized sham-controlled trials. Here is where LLLT genuinely fits in a serious hair loss protocol, and where the marketing oversells the data.
Scalp Massage and Hair Growth: Koyama 2016 Reality Check
Scalp massage has a plausible mechanism and one small study supporting modest effects. The right place is as a daily 4-5 minute adjunct, not a primary therapy.
Rosemary Oil vs Minoxidil: What Panahi 2015 Actually Showed
Rosemary oil produced effects similar to 2 percent minoxidil at six months in Panahi 2015. Real but smaller than the headline implies. Where it actually fits in a hair loss protocol.
Saw Palmetto vs Finasteride: What the Evidence Shows
Saw palmetto inhibits 5-alpha reductase weakly. Finasteride inhibits it strongly. When the natural alternative actually fits the protocol, and when it does not.
The Microneedling Protocol That Actually Works (And the Three Mistakes Most Men Make)
Microneedling is the most evidence-backed adjunct in hair loss, and also the one most men do wrong. Three mistakes flatten results: depth too shallow, frequency too high, and using it as standalone instead of a delivery system.
Topical Finasteride: Less Side Effects, Less Efficacy, or Both?
Topical finasteride is sold as the safer, milder, more local version of the oral pill. The pharmacokinetic data does not support that framing as cleanly as the marketing implies. Evidence-based guide to what topical actually delivers.
Dutasteride vs Finasteride: When the Switch Actually Makes Sense
Dutasteride suppresses DHT more aggressively than finasteride, but its 4-5 week half-life and broader receptor inhibition reshape the entire risk-benefit conversation. Evidence-based guide on when switching actually makes sense.
