Most stores just sell you a product and leave you to figure it out. We don't.
At Cova, we only stock what we genuinely believe works — and we back every order with real guidance on how to get the best results for your specific hair type. No jargon, no guesswork.
We're an authorised K18 retailer, which means every product you receive is 100% authentic — not the counterfeits flooding Amazon and marketplaces right now.

Clinically proven, not just hyped |
Most treatments sit on the surface and wash away within days. K18 works differently — rebuilding your hair from the inside at a molecular level, so every wash leaves it stronger, softer, and more resilient than the last. This isn't a mask. It's a reset.
