Hair care that starts inside.
Rootiva Hair Lab is built around one daily habit: two capsules, every day.
One bottle. Two capsules. Every day.
Hair routines tend to get complicated. We wanted the nutrition step to be the simple part.
Rootiva Hair Density & Strength Complex brings Cynatine® HNS soluble keratin together with biotin, zinc, copper and vitamins A, E, B5, B6 and niacin. The full Supplement Facts are published on every product page.
We don’t promise timelines or results — individual results vary — and we won’t pretend a supplement replaces a balanced diet or advice from your healthcare professional.
Simple, honest, easy to keep
One focused formula
Keratin, biotin, zinc, copper and a handful of vitamins — in two capsules a day.
Plain talk
We tell you what’s on the label and leave out what we can’t back up.
