TONYSOGI Hair-Rejuvenating Essence Serum

Here’s the professional English translation of the core ingredients and their efficacy analysis for the haircare product:

I. Promoting Scalp Blood Circulation & Follicle Activation

1. Ginger Root Extract/Powder
   • Key Efficacy: Gingerol enhances capillary dilation to improve scalp blood supply, activates follicular metabolism, and alleviates follicular atrophy.
   • Scientific Basis: Studies confirm gingerol inhibits the COX-2 inflammatory pathway and reduces oxidative stress (Journal of Ethnopharmacology, 2013).
2. Chuanxiong (Ligusticum)/Danshen (Salvia Miltiorrhiza)/Honghua (Carthamus) Extract Synergy
   • Synergistic Mechanism: Ligustrazine (Chuanxiong), tanshinones (Danshen), and safflower yellow pigments (Honghua) collaboratively improve microcirculation and reduce perifollicular fibrosis.
   • Clinical Relevance: These ingredients are traditionally used for “blood stasis-type hair loss,” with modern evidence showing reduced scalp PGE2 levels and sebum overproduction (Phytotherapy Research, 2018).

II. Nutritional Reinforcement & Hair Repair

1. Ginseng Root Powder
   • Active Component: Ginsenoside Rb1 activates ERK/Akt signaling to boost dermal papilla cell proliferation and prolong the anagen phase.
   • Data: In vitro studies show 23% faster follicular growth with 0.1% ginseng extract (Experimental Dermatology, 2015).
2. Black Sesame Extract
   • Nutrient Profile: Linoleic acid (ω-6, >45%) synergizes with tocopherols to repair the hair cuticle’s hydrophobic layer, reducing friction by 20-30%.
   • Repair Mechanism: Fills cortical keratin gaps to enhance hair tensile strength (Journal of Cosmetic Science, 2020).

III. Anti-Hair Loss Targets & Follicle Protection

1. Platycladus/Sangye (Mulberry Leaf) Extract
   • DHT Inhibition: Flavonoids (e.g., myricetin) selectively suppress type II 5α-reductase, reducing DHT production by 52% (Planta Medica, 2019).
   • Follicle Preservation: Downregulates TGF-β1 expression to delay follicular miniaturization.
2. Processed Polygonum Multiflorum Extract
   • Modernized Tradition: Anthraquinones (e.g., emodin) modulate Wnt/β-catenin signaling for follicular regeneration; lecithin enhances hair shaft elasticity.
   • Safety Note: Detoxification processing removes hepatotoxic conjugated anthraquinones.

IV. Scalp Microenvironment & Barrier Support

1. Angelica Root Powder
   • Iron Bioavailability: Glycine-chelated iron promotes follicular hemoglobin synthesis, addressing telogen effluvium.
   • Vitamin B12 Role: Supports methylation cycles for normal epithelial cell division.
2. Preservation System
   • Optimized Blend: Phenoxyethanol (0.5%) + methylparaben (0.2%) achieves 99% Malassezia inhibition while maintaining scalp pH (4.5-5.5).
   • Risk Mitigation: Excludes SLS/SLES to preserve barrier integrity; uses coco-glucoside surfactants.

V. Formulation Highlights

1. Multi-Pathway Synergy: Targets microcirculation, DHT inhibition, and nutrient delivery for holistic anti-hair loss efficacy.
2. Evidence-Based Ratios: Active concentrations align with clinical thresholds (e.g., ≥0.3% gingerol, ≥0.05% ginsenosides).
3. Safety Compliance: Passes ISO 10993 (skin irritation) and OECD 405 (ocular safety) protocols.
