Description

ULULIS Premium Water Conc. Black Serum Conditioner is a high-concentration rinse-out conditioner formulated for hair that feels persistently dry, damaged, or weakened — whether from colour, bleach, heat, or age-related structural changes. Part of the Japan-domestic ululis Premium lineup sold at Matsumotokiyoshi, this treatment delivers over 95% moisture and repair actives per bottle, making it one of the most densely formulated mass-market conditioners available in Japan today.

Tosurea and PDRN are the two hero actives that set this apart from standard conditioners. Tosurea is a next-generation bonding repair ingredient that targets damaged areas along the hair shaft, rebuilding structural integrity from within. PDRN — a precision moisture-binding compound used in advanced skincare — works at a cellular level to restore deep hydration. Together, they address damage that surface-coating silicone products cannot reach. Alongside these, Black Serum Water — a proprietary blend of fermented black rice extract, black soy peptide, and black pearl protein — penetrates to strengthen the hair fibre and improve resilience against heat and friction.

Collagen water and keratin water are formulated at 10× the concentration of the standard ululis range, locking repair actives inside the strand and delivering a noticeably smoother texture from first use. The scent is a refined black floral that fades cleanly. Pairs well with the ululis Premium Water Conc. Black Serum Shampoo for the full-line repair system.

Key Ingredients
  • Tosurea (Ammonium Diaminoethyl Thiosuccinate) — next-generation bonding repair active that attaches to damaged sites inside the hair shaft and rebuilds structural integrity
  • PDRN (DNA-Na) — precision moisture-binding ingredient that restores cellular-level hydration deep within the hair cortex
  • Black Serum Water Complex — 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 — formulated at 10× 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) — biotech-derived ingredient supporting the hair barrier and surface smoothness

HOW TO USE
  1. Shampoo hair and rinse thoroughly.
  2. Squeeze out excess water — 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 10× 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 — a palm-sized portion for medium-length hair — 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 — 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 — not an export reformulation or parallel import from a third-party warehouse.
