ULULIS Black Serum vs &honey Deep Moist Hair Oil:
Which Repairs Better?
Both the ULULIS Premium Black Serum Hair Oil and the &honey Deep Moist Hair Oil 3.0 are stocked by TokyoShelf โ and people frequently ask which one to choose. They're priced similarly, both are Japanese domestic formulas, and both claim to repair damaged hair. But the underlying approach is completely different, and the right choice depends on what your hair actually needs.
Product Profiles
Structural repair oil using biomedical actives. Built on the Water Conc. philosophy โ 95%+ water-soluble repair actives. Launched 2026.
Intensive moisture oil using botanical and apiary actives. Natural-ingredient focus with high honey, royal jelly, and argan oil concentration.
Formula Philosophy โ Two Different Approaches
ULULIS Black Serum is built on biomedical repair technology. PDRN (Polydeoxyribonucleotide) originates from regenerative medicine; Tosurea targets broken disulphide bonds inside the hair cortex. The formula absorbs into the shaft and works structurally โ the improvement accumulates over weeks because the repair compounds are genuinely rebuilding internal structure.
&honey Deep Moist 3.0 is built on botanical intensity. At 99% natural-origin ingredients, it delivers moisture through organic honey (a potent humectant and antioxidant), royal jelly EX (protein and lipid-rich), and Moroccan argan oil. It coats and conditions with exceptional richness โ the effect is immediate, sensory, and highly effective for extreme dryness.
Head-to-Head: 10 Categories
| Category | ๐ค ULULIS Black Serum | ๐ฏ &honey Deep Moist 3.0 |
|---|---|---|

| Frizz control (cumulative) | Improves over weeks as internal structure repairs Builds | Consistent but not cumulative โ resets each wash |
| Build-up risk | Low โ water-soluble base Better | Moderate โ honey and oil can accumulate |

Side-by-Side Ratings
For Damaged Hair Specifically
This is where the two products diverge most clearly. Bleaching and chemical processing cause three types of structural damage: broken disulphide bonds inside the cortex, degraded moisture retention capacity, and protein voids. The ULULIS Black Serum addresses all three through PDRN (moisture), Tosurea (bonds), and 10ร keratin (protein). The &honey formula provides intense surface conditioning but its actives don't penetrate the cortex to work structurally.
| Damage Type | ULULIS Black Serum | &honey Deep Moist 3.0 |
|---|---|---|
| Broken bonds (bleach, perm) | โ Tosurea bonds directly to break sites | โ Surface conditioning only |
| Internal moisture loss | โ PDRN restores cellular moisture capacity | โ Honey adds external moisture โ washes off |
| Protein voids | โ 10ร hydrolysed keratin fills cortex gaps | โ Hydrolysed silk provides some surface fill |
| Cuticle damage | โ 10ร collagen water seals cuticle | โ Honey + argan smooth cuticle effectively |
| Breakage / elasticity loss | โ Bond repair reduces snap-breakage | โ Conditioning reduces friction-breakage |
| Dryness between washes | โ Structural fix holds through multiple washes | โ Good same-day; resets with each shampoo |
For hair with no significant chemical damage โ colour-healthy, naturally dry, or just wanting richness and gloss โ &honey's botanical intensity is genuinely excellent and may be the more enjoyable product to use day-to-day. The repair argument only tips decisively toward ULULIS when there's real structural damage underneath.
