Questions? We've got you.

When will I get my order?

We’re currently in our limited first-batch preorder phase. Orders will ship shortly after the preorder period ends. We’ll keep you updated every step of the way and send you a tracking link as soon as your Kerovu order is on its way.

Can I cancel before it ships?

Yes. You can cancel your preorder anytime before it ships, no questions asked. Once your order is on the way, our standard return policy applies.

How do I pick my shade?

We’ve made it simple. Each shade is designed to blend naturally with your hair color, so you don’t need an exact match. If you’re between two shades, we recommend going slightly darker — it creates a more natural, fuller look.

**Colors may vary slightly by screen and lighting.

Is it safe for sensitive skin?

Kerovu fibers are made with cosmetic-grade ingredients commonly used in hair and skin products. They sit on your hair, not your scalp, and wash out with shampoo. If you have very sensitive skin, we recommend doing a quick patch test first.
