— THE SERIVA WAY
Made for my wife. who'd tried everything
When my wife started shedding, she stopped wearing her hair down and stopped feeling like herself.
Nothing on the shelf actually helped. So I built something that would.

— QUESTIONS
Before you begin
When will I see results?
Most women notice less shedding by week 4 to 6. New growth at the temples and crown usually shows up between weeks 8 and 12. The biggest factor is taking it every day without skipping.†*
Can I take it with other supplements?
Yes. Seriva is made to replace your daily hair vitamin, not stack on top of one. If you take a multivitamin or other supplements for your diabetes, those are fine to keep — and you can always check with your doctor if you want to be sure.‡
Is it vegan?
Not fully. Seriva contains marine collagen and a few other ingredients sourced from the ocean, so it is not vegan. It is gluten-free, dairy-free, and made without artificial colors, sugar alcohols, or aftertaste.
What is your return policy?
Try Seriva for 120 days. If you do not see less shedding and stronger hair, send the bottle back, even if it is empty, and we will refund you in full. No questions, no follow-up emails.
