Quick checklist
- Confirm the listing shows “System 3” and the Sebastian Dark Oil in the bundle before checkout.
- Use in order: cleanse first, then condition, apply the treat step, finish with a small amount of oil on mid-lengths to ends.
- Start with a pea-size amount of oil and add only if needed to avoid weighing hair down.
- Store products in a cool, dry place away from direct heat or sunlight.
- If you color hair, follow color-care directions and check compatibility notes on the Amazon listing.

If you’re hesitating
- Will it feel heavy? The Sebastian oil is promoted as lightweight; start with a small amount.
- Is it only for colored hair? The System 3 is labeled for colored, dry, damaged hair but may suit anyone with similar texture concerns.
- How many steps? It’s a straightforward 3-step core routine plus the oil for styling.
This bundle earns a spot for anyone who wants a compact, repeatable routine that cleanses, conditions, treats, and finishes without heavy styling products. Makes sense for shelf stashes and sensible gifting when you want something that gets used.
