Organic argan oil has a very small molecular structure that easily penetrates and smooths the cuticle layer as it repairs damage in the deepest areas while restoring strength. Argan oil provides a natural micro-barrier that protects from styling heat and UV rays. The result is brilliant shine with a silky-soft feel for healthy, beautiful hair. How it works: Our original argan oil treatment has many beneficial uses. This very small molecular structure penetrates deep into hair while conditioning, strengthening, repairing and smoothing the cuticle layer without adding weight or residue.
