Description

ULULIS Premium Water Conc. Black Serum Conditioner 335g is a high-concentration rinse-off conditioner for persistently dry, damaged, and colour-treated hair β€” the sealing step in the ululis Premium Black Serum system, completing the Tosurea and PDRN repair cycle started by the Black Serum Shampoo. It delivers over 95% moisture and repair actives in a single rinse-off step that leaves hair noticeably more resilient and frizz-resistant after each use.

  • Tosurea (Ammonium Diaminoethyl Thiosuccinate) β€” continues bonding to damaged sites after the shampoo step, maximising repair coverage
  • PDRN (DNA-Na) β€” extends the cellular-level moisture binding started by the shampoo, sealing hydration inside repaired zones
  • 10x concentrated Collagen Water and Keratin Water β€” fills and seals surface and internal damage
  • Black Serum Water complex β€” multi-active conditioning complex that strengthens each strand
  • Refined black floral scent β€” the signature ululis Premium fragrance
  • 335g β€” apply to damp hair after shampooing; leave 1–2 minutes then rinse

How it works: The conditioner applies a second dose of Tosurea and PDRN immediately after the shampoo has prepared the hair surface β€” maximising the total amount of repair material that bonds to damaged zones in one wash session. PDRN's moisture binding in the conditioner layer is sealed in during rinsing as the cuticle closes, providing a sustained moisture reservoir that prevents the dryness that typically returns within a day of washing with standard products.

ULULIS Premium Black Serum Conditioner vs Black Serum Hair Oil: The Conditioner is the rinse-off step used in the shower after every wash β€” it provides internal repair and moisture sealing. The Black Serum Hair Oil is the leave-in finishing step applied to towel-dried hair β€” it adds shine, heat protection, and frizz control on top of the conditioning base. Both are needed for the complete system; the Conditioner alone does not replace the Hair Oil's leave-in function.

Key Ingredients
  • Tosurea (Ammonium Diaminoethyl Thiosuccinate) β€” next-generation bonding repair active that attaches to damaged sites inside the hair shaft and rebuilds structural integrity
  • PDRN (DNA-Na) β€” precision moisture-binding ingredient that restores cellular-level hydration deep within the hair cortex
  • Black Serum Water Complex β€” fermented black rice extract, black soy peptide, and black pearl protein combined to penetrate the strand and increase fibre strength and resilience
  • Soluble Collagen Water + Hydrolysed Keratin Water β€” formulated at 10Γ— the concentration of the standard ululis line; wraps each strand in a moisture film and locks repair actives inside
  • Exosome (Human Adipose-Derived Mesenchymal Cell Exosome) β€” biotech-derived ingredient supporting the hair barrier and surface smoothness

HOW TO USE
  1. Shampoo hair and rinse thoroughly.
  2. Squeeze out excess water β€” hair should be damp, not dripping.
  3. Dispense an appropriate amount into your palm and spread evenly through mid-lengths to ends, avoiding the scalp.
  4. Leave on for 1–2 minutes, then rinse thoroughly with lukewarm water.
  5. Pro tip: For bleached or heavily processed hair, extend the leave-on time to 3–5 minutes and use a wide-tooth comb to distribute evenly before rinsing. This allows Tosurea and PDRN to bond more deeply before the treatment is washed out.

FAQ

How is the ululis Premium Black Serum Treatment different from the standard ululis Moist Treatment?

The standard ululis Moist Treatment (blue bottle) is formulated at 90%+ moisturising components and is excellent for preventing everyday dryness. The Premium Black Serum steps up significantly: 95%+ moisture and repair actives, Tosurea and PDRN for structural repair rather than surface conditioning, and collagen and keratin water at 10Γ— the concentration. If your hair has visible damage, colour fatigue, or texture changes, the Premium Black Serum is the more targeted option.

Can I use this on fine hair without it feeling heavy?

Yes. Despite the high active concentration, the formula is designed to rinse clean without weighing hair down. Multiple reviewers on @cosme and LIPS with fine or volume-sensitive hair note the treatment gives moisture and softness without flatness. The key is using the right amount β€” a palm-sized portion for medium-length hair β€” and rinsing thoroughly.

Is this suitable for colour-treated or bleached hair?

Yes, and it's specifically designed with this concern in mind. Tosurea and PDRN address the inner cortex damage caused by chemical processing, while the Black Serum Water complex helps reinforce the strand surface. The formula is also free from sulfates and petroleum surfactants that can accelerate colour fade.

How does this compare to the Shiseido Fino Premium Touch Hair Mask?

The Fino Premium Touch Hair Mask is a rinse-out treatment known for intense royal jelly conditioning β€” rich, deeply softening, particularly effective on very dry or coarse hair. The ululis Premium Black Serum Treatment focuses more on repair through next-gen biotech actives (Tosurea, PDRN, exosomes) and structural rebuilding. Fino excels at immediate softness and slip; ululis Premium is better suited for hair where the goal is long-term resilience and damage repair alongside hydration.

Is this the Japan-domestic version?

Yes. TokyoShelf sources this product directly from Japan's domestic retail network, including Matsumotokiyoshi, where it is sold to Japanese consumers. The packaging carries full Japanese labelling as required under Japanese cosmetics law, and the formula is the Japan-domestic version β€” not an export reformulation or parallel import from a third-party warehouse.
