Deep-Treat While You Dream

The Oil Night Long Set pairs three complementary growth oils designed for layering or rotation in your nightly ritual. Each bottle targets a different barrier to length, from sluggish follicles to weakened bonds, so you wake up to stronger, glossier hair without greasy build-up.

Formulated without sulfates, silicones, mineral oil or animal testing, each dry-touch blend soaks in fast yet works for up to 8 hours, giving you effortless “beauty-sleep” growth.

What’s Inside This Set:

  1. Rosemary Hair Oil Intense Growth Syrup 100ml
  2. Castor Camellia Root Renewal Hair Oil 100ml
  3. Argan Almond Bond Boost Hair Oil 100ml
