Sebastian Dark Oil Smooth and Shine Conditioner – 33.8 fl oz, lightweight detangling with jojoba & argan

Sebastian Professional Dark Oil Smooth and Shine Conditioner is a detangling, lightweight conditioner formulated with jojoba and argan oils to leave hair smooth, shiny and softly fragranced.

This salon-grade conditioner belongs to Sebastian's Dark Oil collection and is designed to complement daily washing for all hair types. It combines lightweight conditioning agents with botanical oils to reduce friction and enhance surface shine without weighing hair down. Use after shampooing to aid comb-through, improve manageability and build a soft, luminous finish that pairs well with the Dark Oil Styling Oil.

How does this conditioner improve detangling and manageability?

The formula smooths hair cuticles and adds slip so combs and fingers glide through wet strands with less breakage. Jojoba and argan oils help soften fibers while conditioning agents coat the hair to minimize friction during brushing. Results are easier styling and reduced tugging when towel-drying or combing.

• Lightweight conditioning reduces knotting without heavy residue
• Botanical oils add slip for gentler detangling
• Coats hair to protect during wet handling
• Rinses clean to maintain volume and body

Will Dark Oil Conditioner weigh down fine hair or make it greasy?

This conditioner is formulated to be lightweight so it conditions without heavy buildup that flattens fine hair. Applied primarily to mid-lengths and ends, it leaves fine strands with body and shine rather than oiliness. For oily roots, avoid direct scalp application and focus on lengths where moisture and detangling are needed most.

• Use sparingly at roots to prevent greasiness
• Concentrate product on mid-lengths and ends
• Rinse thoroughly to maintain lift at the crown
• Suitable for daily or regular use depending on hair needs

How should I use Dark Oil Conditioner in my routine?

After shampooing, distribute an appropriate amount evenly through damp hair and leave for a minute or two before rinsing. For targeted repair, leave on slightly longer on particularly dry ends. Follow with Sebastian Dark Oil Styling Oil for enhanced shine and frizz control, or style as usual for lightweight, soft finish.

• Apply post-shampoo to damp hair—focus on lengths and ends
• Leave in briefly for light conditioning; rinse thoroughly
• Pair with Dark Oil Styling Oil for added shine and control
• Can be used daily or as needed for detangling
