Sebastian Professional Dark Oil Styling Oil 95ml is a lightweight hair-finishing oil that smooths, shines and softens in a single pass — and is widely regarded as one of the best-performing styling oils on the professional market. Argan oil is supported by a signature blend of sandalwood and cedarwood, giving the product its dark, sophisticated colour and its trademark warm-woody, distinctly grown-up fragrance.

Key ingredients
- Argan Oil (Argania Spinosa Kernel Oil) — Moroccan plant oil rich in vitamin E and oleic acid; smooths the cuticle and adds gloss.
- Sandalwood Oil (Fusanus Spicatus) — soft, warm aromatic note that contributes to the signature fragrance.
- Cedarwood Oil (Juniperus Mexicana) — adds depth and that distinctive woody aroma.
- Cyclopentasiloxane and Dimethiconol — silicone-based slip and shine agents that flash off without weighing the hair down.
- Ethylhexyl Methoxycinnamate — UV filter that helps protect against the visible effects of sun exposure on hair.
What it does
- Smooths hair for up to 48 hours
- Tames frizz and flyaways
- Adds glossy shine without weighing hair down
- Improves combability and softness
- Provides UV protection against sun damage
- Disappears into the hair in seconds — no greasy residue

Who it's for
Best suited to dry, frizz-prone, rebellious or damaged hair, but the lightweight formula is also gentle enough to use on all hair types — fine and oily included — as long as application is moderate. Particularly useful for thick, coarse or curly hair that needs taming and gloss, and for those who want a finishing oil that doubles as a subtle hair fragrance.
How to use
- Dispense 1–3 pumps into the palms, depending on hair density and length.
- Rub the hands together to distribute the oil evenly.
- Apply through damp hair before styling to smooth the cuticle and prime for heat protection.
- Or apply to dry, finished hair for an instant smoothing and shine top-coat.
- Focus on mid-lengths and ends; use sparingly near the roots, especially on fine hair.
