Procerin has been on the market for over 20 years — longer than Hims, Keeps, or most telemedicine hair loss brands. That's a lot of user experience to draw from. Here's what actual users report, including feedback from participants in the IRB-approved clinical study.
Clinical Study Participant Feedback
Procerin's IRB-approved clinical study included video interviews with participants who used the product. Several consistent themes emerge from their feedback:
"I noticed a significant difference in the thickness of my hair after using Procerin consistently for about 4 months. The shedding slowed down first, and then I started seeing regrowth in areas that had been thinning."
"What I liked about Procerin is that it was natural. I didn't want to deal with the side effects of finasteride — I'd read about them and they concerned me. With Procerin, I haven't had any side effects at all, and my hair loss has definitely slowed down."

Common User Experiences
Based on reported user feedback over 20+ years, here are the patterns:
What Users Like
- No side effects — the most frequently cited positive
- Reduced shedding within 2–3 months
- Gradual thickening of existing hair
- Easy to use (daily capsules + topical)
- 90-day guarantee reduces financial risk
- Natural ingredients feel safer than prescription
Common Complaints
- Results take 3–6 months — requires patience
- Won't reverse advanced baldness (Norwood V+)
- Must be used consistently — miss doses, lose ground
- Some users see maintenance (no further loss) rather than visible regrowth
- Monthly cost adds up over years of use
Who Reports the Best Results?
The pattern from user feedback is consistent with the clinical data:
- Best outcomes: Men under 40, Norwood II–III, who use both capsules and topical consistently for 6+ months
- Moderate outcomes: Men in their 40s–50s at Norwood III–IV — typically see slowed progression and some thickening
- Limited outcomes: Men with advanced loss (Norwood V+) — most report maintenance at best
Procerin combo: oral capsules + XT topical activator.
Procerin Rx User Feedback
Procerin Rx — prescription topical for moderate-to-advanced loss.
Procerin Rx is newer to market, so the user experience base is smaller. Early feedback highlights:
- Users appreciate the single topical application (vs. pill + separate topical with Hims/Keeps)
- Topical finasteride is preferred by men who tried oral finasteride and experienced side effects
- Onset of visible improvement is reported at 4–6 months
- The telemedicine process is described as quick and straightforward
