Why Single Donor Matters
One donor.
Every bundle.
No exceptions.
Most hair brands blend bundles from dozens of donors. That means mismatched cuticle directions, tangling, and hair that degrades fast. S. Riviere does not do that.
Every bundle comes from a single donor, unprocessed, temple-sourced from South India, cuticle-aligned root to end. It behaves like your own hair because it was grown the same way.
