Frequently asked questions
Straight answers about the formula, subscriptions, shipping and returns.
How many capsules should I take?
Take 2 capsules daily. Please don’t exceed the recommended serving. One bottle holds 60 capsules — a 30-day supply.
What’s in Rootiva Hair Density & Strength Complex?
Keratin complex (Cynatine® HNS, 500 mg), biotin (3,000 mcg), zinc (15 mg), copper (1.65 mg) and vitamins A, E, B5, B6 and niacin. See the full Supplement Facts.
Does biotin affect lab tests?
Yes — biotin can interfere with certain laboratory tests. Tell your healthcare provider you take a biotin-containing supplement before any blood work.
When will I notice a difference?
We don’t promise a timeline: individual results vary, and hair goes through growth cycles over months. Consistent daily use matters more than speed. If it isn’t for you, see our 30-day return policy.
Who should check with a doctor first?
Anyone who is pregnant or nursing, takes medication, or has a medical condition should speak with a healthcare professional before using any dietary supplement.

Subscribe and save 10% on a 1-month bottle, 20% on a 3-month supply or 25% on a 6-month supply. A new supply ships every 30, 90 or 180 days with free shipping, and you can skip, pause or cancel from your order email.
What are the shipping costs?
Standard shipping is $6.95 (3–5 business days) and free on every subscription and on one-time orders over $99. Express is $14.95 (1–2 business days). We ship within the United States.
