Frequently Asked Questions

[{"q":"What is DHT and why does it cause hair loss?","a":"DHT (dihydrotestosterone) is an androgen hormone derived from testosterone via the enzyme 5-alpha-reductase. In men with a genetic predisposition to male pattern baldness, DHT binds to androgen receptors in scalp follicles and triggers a progressive miniaturization process — shortening hair growth cycles and gradually reducing follicle size until hair stops growing. Not all men are susceptible; genetic androgen receptor sensitivity is the determining factor."},{"q":"What does a DHT blocker actually do?","a":"A DHT blocker reduces DHT's effect on hair follicles, either by inhibiting 5-alpha-reductase (reducing DHT production from testosterone) or by blocking DHT at the androgen receptor. The goal is to slow or halt follicle miniaturization in men with androgenetic alopecia. DHT blockers do not typically reverse advanced hair loss — they're most effective at preserving existing hair in the early-to-mid stages of thinning."},{"q":"What's the difference between natural and pharmaceutical DHT blockers?","a":"Pharmaceutical DHT blockers like finasteride and dutasteride are potent 5-alpha-reductase inhibitors with strong clinical evidence for halting and partially reversing hair loss. They also carry a risk of side effects including sexual dysfunction in a minority of users. Natural DHT blockers (saw palmetto, beta-sitosterol, pumpkin seed oil) have a modest but real evidence base, work more gently on the 5-AR pathway, and have a much lower reported side effect profile. The tradeoff is potency: natural options are less likely to produce dramatic results but are better tolerated."},{"q":"Does saw palmetto actually work for hair loss?","a":"Yes, with realistic expectations. Multiple clinical studies show saw palmetto produces measurable improvement in hair density and hair count in men with androgenetic alopecia — better than placebo, but less effective than finasteride. A 2012 randomized trial showed 38% of men taking saw palmetto showed improvement vs. 66% for finasteride. Saw palmetto is a legitimate option for men in early stages of hair loss who want to address DHT without pharmaceutical side effect risk."},{"q":"Can a DHT blocker regrow hair I've already lost?","a":"Possibly, in follicles that are miniaturized but not completely dormant. Once a follicle has fully miniaturized and ceased activity, regrowth is unlikely from DHT blocking alone. The earlier you intervene, the better the odds of preserving and potentially recovering some hair. Men in early stages (Norwood I–III) see the best results."},{"q":"How long before I see results from a DHT blocker?","a":"Hair growth cycles are 3–6 months long. Most men require 6–12 months of consistent use before meaningful results are visible. Early signs — reduced shedding and improved hair texture — may appear sooner. Stopping treatment typically causes any gains to reverse within months, as DHT-driven miniaturization resumes."},{"q":"Is finasteride safe?","a":"Finasteride is well-tolerated by most men and has a decades-long clinical record. However, a subset of users — estimated at roughly 1–2% in clinical trials, though self-reported rates vary — experience sexual side effects including reduced libido and erectile dysfunction. In most cases these resolve after stopping the medication. A smaller group reports persistent symptoms after discontinuation (Post-Finasteride Syndrome). Anyone considering finasteride should review these risks with a physician."},{"q":"What is Procerin?","a":"Procerin is a two-part hair loss supplement system — an oral tablet and a topical serum — formulated with natural DHT-blocking ingredients including saw palmetto and beta-sitosterol. It is backed by an IRB-approved double-blind clinical study, which is uncommon for over-the-counter supplements. It is designed for men with androgenetic alopecia in the early-to-moderate stages.
