Product details

Sebastian Professional Dark Oil Smooth and Shine Mask is a lightweight, deeply nourishing hair mask infused with jojoba and argan oils to add smoothness, shine, and a captivating scent.

This intensive mask from Sebastian's Dark Oil line delivers rich conditioning without weighing hair down. Formulated to work across hair types, it blends jojoba and argan oils to replenish moisture, tame frizz, and amplify shine while leaving a memorable fragrance. Use it as part of the Dark Oil routine to enhance manageability and surface gloss after cleansing.

How does this mask improve dry or frizzy hair?

The mask replenishes lipids and hydrates the hair fiber, reducing surface roughness that causes frizz and dullness. Lightweight oil extracts smooth the cuticle for easier combing and reduced static without creating greasiness.

  • Argan oil helps soften and restore flexibility to brittle strands.
  • Jojoba oil mimics natural sebum to seal moisture without residue.
  • Rich emollients smooth the hair surface for less frizz and more shine.
  • Designed to rinse clean for weightless movement.

When and how should I use the Dark Oil Smooth and Shine Mask?

Apply the mask after shampooing for an in-salon deep treatment or use weekly as a targeted repair step. Leave it on according to your hair's needs, then rinse thoroughly to reveal softer, glossier hair.

  • Use after cleansing: apply mid-lengths to ends, leave 3–10 minutes depending on porosity.
  • For intensive repair, extend processing time or use heat cap briefly.
  • Rinse completely to maintain a non-greasy finish and natural movement.

Will this mask work with colored or chemically treated hair?

The formula is suitable for color-treated and chemically processed hair because it focuses on replenishment and cuticle smoothing rather than coating. Regular use helps improve manageability and shine, supporting professional color and chemical services when incorporated into a maintenance routine.

  • Supports color vibrancy by smoothing the hair surface for better light reflection.
  • Helps reduce breakage and split ends from chemical processing.
  • Safe to use as part of a salon or at-home maintenance schedule.

Who is this for? Sebastian Dark Oil Smooth and Shine Mask is formulated for anyone seeking deep conditioning without heaviness—ideal for fine to coarse textures, natural or chemically treated hair, and those who want instant shine plus a luxurious scent. Available in a 16.9 fl oz size for salon-style treatments at home; packaging may vary.
