Before & After
Real Customer Experiences
"2-inch baby hairs growing back in my thinning areas. I was on Nutrafol for a year with zero results. This is the only supplement that has ever worked for me."
"My nails stopped splitting at 3 weeks. My hair was noticeably less in the drain at 6 weeks. I will subscribe forever."
"Post-menopause hair thinning is real and brutal. At month 3 I photographed my part — the difference was undeniable. These are real doses. That's why it works."
Frequently Asked Questions
Will this cause breakouts?
High-dose biotin causes acne in people deficient in B5 (Pantothenic Acid). We include 30mg of B5 specifically to prevent this. If you still experience breakouts, start with 1 capsule daily for 2 weeks before increasing to 2.
What if it doesn't work for me?
30-day full refund, no questions. Contact support@gennsy.com. If you don't see a change in shedding or nail strength within 30 days, we'll refund you. We stand behind the formula.
How long until I see results?
Hair grows ½ inch per month. Week 2–3: less shedding. Month 1: stronger nails. Month 2: baby hairs at the hairline. Month 3: visible fullness. Photograph your part every 4 weeks under the same light.
Safe during pregnancy or nursing?
Please consult your doctor before taking this supplement during pregnancy or nursing. The formula includes Iron, Folate and other nutrients commonly found in prenatal vitamins, but the specific dosages should be reviewed by your provider.
How To: Daily Routine
Take 2 capsules with breakfast
Fat-soluble vitamins (A, D, E, K) absorb better with food. Pair with a glass of water. Make it part of your morning ritual .
Photograph your progress
Take a photo of your part under the same light every 4 weeks. Hair change is gradual — side-by-side comparison is how you see it.
