Built for thick, curly hair.
Light enough for the rest.

radiance by k. shampoo and conditioner

GHK-Cu copper peptide shampoo and conditioner from Radiance by K.

Kay started this at 16 after years of bottles that never worked on her curls. Friends with finer hair borrowed a bottle anyway. It still felt clean, soft, and easy to manage.

It started with her hair.

About Kay

Hi, I’m Kay. I’m 16.

I started Radiance by K with my dad after years of buying products that never worked for my thick, curly hair. When nothing met my standards, we spent months testing formulas until we finally found one that did. My hair is the healthiest and softest it’s ever been — and that’s why this exists.

We built it for curls, but people with thinner hair tried it too. Same two bottles. Different hair. Easier routine.

The set

Two bottles. One routine.

500 ml each. Formulated with GHK-Cu copper peptide. Made to clean without stripping and condition without weighing hair down.
