Infused with a blend of Argan, Lemon, and Marula Oil, the range works across all hair types to tame frizz, add shine, and leave hair feeling weightlessly silky. Whether you're looking for a daily ritual or a deep treatment, there's a Dark Oil product for every step of your routine.

The Full Dark Oil Range

Cleanse

Sebastian Dark Oil Shampoo 250ml
Start your routine with this gentle, sulphate-free shampoo that cleanses without stripping. It preps hair for the full Dark Oil experience, leaving it soft and ready to absorb the nourishing treatments that follow.

Sebastian Dark Oil Conditioner 250ml
Pair with the shampoo for a complete cleansing ritual. This conditioner detangles and smooths, delivering instant softness and manageability from root to tip.

Sebastian Dark Oil Conditioner 1000ml (with free pump)
The salon-size option — ideal for those who can't get enough. The free pump makes application effortless, and the larger format is excellent value for regular use.

Sebastian Dark Oil Shampoo & Conditioner Duo 250ml
The perfect introduction to the range — or a travel-friendly pairing. Both products together at a great value.

Treat

Sebastian Dark Oil Lightweight Hair Mask 150ml
A weekly indulgence that delivers deep nourishment without weighing hair down. Ideal for fine to medium hair that needs moisture and shine without heaviness.

Sebastian Dark Oil Lightweight Hair Mask 500ml
The full-size version for those who've made the mask a non-negotiable part of their routine. Rich, restorative, and utterly luxurious.

Style & Finish

Sebastian Dark Oil 30ml
The iconic oil itself — a multi-tasking styling treatment that can be used on damp or dry hair. Apply a few drops to smooth frizz, add mirror-like shine, and protect against heat. The 30ml size is perfect for on-the-go touch-ups.

Sebastian Dark Oil 100ml
The full-size oil for everyday use. A little goes a long way — work through mid-lengths and ends before blow-drying, or use on dry hair for an instant glossy finish.

Sebastian Dark Oil Taming Elixir 140ml
A lightweight, leave-in elixir that tames flyaways and adds a sleek, polished finish. Perfect for those who want control without stiffness — ideal for blow-dry prep or finishing.

Sebastian Dark Oil Silkening Fragrant Mist 200ml
The finishing touch. This fragrant mist adds a veil of silkiness and a signature Dark Oil scent — a sensory ritual as much as a styling step. Spritz over styled hair for a luminous, touchable finish.

How to Build Your Dark Oil Routine

For everyday smoothness: Shampoo → Conditioner → Dark Oil (Styling)

For a weekly treatment: Shampoo → Hair Mask → Dark Oil or Taming Elixir

For a finishing touch: Silkening Fragrant Mist over any styled look

For fine hair: Opt for the Lightweight Hair Mask and the Taming Elixir over the heavier oil
