Smoother, frizz-free hair – shipped to the US
Nanokeratin System is a professional hair-care brand by NKS Laboratories. Here you can choose smoothing aftercare, at-home smoothing and curl care by hair type, and order it directly from our official store with delivery to the US.
Not sure where to start? The Hair Finder asks two questions – your goal and whether the product is for salon or home use – and shows the products that match.
Why hair loses its smoothness in the US
From humid summers in the South and on the East Coast to hard water in many cities, the US is tough on smooth hair. Matching aftercare to your hair type and adding a humidity-protection step is what keeps results looking smooth for longer.
Aftercare by hair type
- Natural hair – Revive: shampoo, mask and aftercare for natural, untreated hair.
- Colored hair – Refine: care designed for color-treated hair.
- Blonde, bleached and highlighted hair – Replenish.
- Thick, resistant and textured hair – Refortify.
After every smoothing treatment, for every hair type, we recommend Reinvent Insulator. It is designed to insulate hair against humidity, salt water, pool chlorine and UV.

Smoothing at home
Resmooth Home Use Kit (softSmooth) is made for soft, natural smoothing with a complementary home care routine. See the full Resmooth range. Instructions for use are included with your order.
Curly and wavy hair
If you want to keep your curls rather than straighten them, Relaminate is our curl lamination system for naturally curly and wavy hair. It is designed to define curls and preserve the natural curl pattern – it is not a perm.
