The SHISEIDO Aquair Hydration Shampoo 600ml is a "daily hydration-focused shampoo" under Shiseido’s Aquair sub-brand, designed to solve common hair dryness issues and meet the basic moisture needs of most users. Its core features are:

1. Professional Hydration Technology: Adopts Aquair’s iconic "Moisture-Lock Complex"—a blend of hyaluronic acid, glycerin, and camellia oil. This complex penetrates hair cuticles to replenish moisture, forms a protective film on hair strands, and locks in moisture for long-lasting hydration (up to 24 hours, per brand testing).
2. Mild & Gentle Cleansing: Uses a combination of amino acid-based and mild anionic surfactants—effectively removes daily dirt, excess oil, and light styling product residue without stripping hair’s natural moisture. It has a pH close to that of hair (4.5-5.5), minimizing irritation to hair and scalp.
3. 600ml Large-Capacity Design: Optimized for family and long-term use— the durable plastic bottle with an easy-pour cap (or pump dispenser in some versions) is convenient to use and store; the large capacity reduces the frequency of repurchasing, saving time and cost.
4. Refreshing Texture & Scent: Has a lightweight, non-greasy liquid texture— it lathers quickly and rinses easily, leaving no sticky residue. The fragrance is a fresh, aquatic floral scent (signature of Aquair), providing a pleasant sensory experience during washing.
5. Synergy with Aquair Conditioners: Formulated to work with Aquair’s Hydration Conditioner— the shampoo cleanses and primes hair for moisture absorption, while the conditioner deepens hydration and smoothness, creating a "complete moisture care cycle."

（specific ingredients subject to product packaging; common core components listed below）：Core Hydration Ingredients:
Sodium Hyaluronate (Hyaluronic Acid): A multi-molecular moisturizer— attracts up to 1000x its weight in water, penetrates hair cuticles to replenish deep moisture, and forms a moisture-locking film on hair strands to prevent water loss.
Glycerin: A classic humectant— absorbs moisture from the air and retains it in hair, relieving dryness and frizz, and keeping hair soft and pliable.
Camellia Japonica Seed Oil: Natural plant oil— rich in oleic acid and vitamin E, it nourishes hair fibers, repairs minor cuticle damage, and enhances the hair’s ability to retain moisture.
Mild Cleansing Ingredients:
Sodium Cocoyl Glutamate: Amino acid-based surfactant— derived from natural coconut oil, it produces mild, rich lather, cleanses gently without stripping hair’s natural sebum, and is non-irritating to sensitive scalps.
Sodium Laureth Sulfate (SLES, low concentration): Mild anionic surfactant— enhances cleansing power and lathering ability, but is used in low concentrations (combined with amino acid surfactants) to balance efficacy and mildness.
Solvent & Stabilizing Ingredients:
Purified Water: Main solvent— undergoes multi-stage filtration (including reverse osmosis) and UV sterilization to remove impurities and bacteria, ensuring the stability and safety of other ingredients.
Cocamide DEA: Surfactant booster— improves lathering quality, thickens the shampoo’s texture, and enhances the compatibility of other ingredients, making the formula more stable.
Safety & Mildness Assurance:
"3-Free" Formula: Free of alcohol (dries out hair/scalp), synthetic dyes (causes irritation), and strong synthetic fragrances (uses mild, natural aquatic floral scents compliant with IFRA standards).
All ingredients comply with Japan’s MHLW (Ministry of Health, Labour and Welfare) cosmetic regulations, EU CosIng standards, and China’s NMPA requirements. The product undergoes strict skin and scalp irritation tests to ensure safety for daily use.

Pre-Use Preparation:
Wet hair thoroughly with warm water (avoid hot water, which can damage hair cuticles and strip moisture); gently squeeze out excess water from hair (hair should be damp to ensure the shampoo lathers evenly).
Shampoo Application & Lathering:
Take an appropriate amount of shampoo (about 5-8ml for medium-length hair; adjust based on hair length and thickness) and apply it to the palms of your hands.
Rub your palms together to create a rich, fluffy lather (lathering first in hands helps reduce direct friction between shampoo and hair); then spread the lather evenly over the scalp and hair.
Gentle Cleansing:
Use your fingertips (not nails) to massage the scalp in circular motions for 1-2 minutes— focus on cleansing the scalp (where dirt and oil accumulate) while gently working the lather through the mid-lengths and ends of the hair.
Avoid rubbing hair vigorously (this can cause tangling, breakage, and further dryness).
Thorough Rinsing:
Rinse the shampoo thoroughly with warm water— ensure no residue remains (residue can cause scalp itching, dull hair, or reduce the efficacy of subsequent conditioner); rinse until the water runs clear and hair feels smooth.
Post-Use Care (Optional but Recommended):
For enhanced hydration, follow with Aquair Hydration Conditioner: Apply the conditioner to mid-lengths and ends (avoid the scalp), leave it on for 1-2 minutes, then rinse.
After washing, gently pat hair dry with a soft towel (do not rub) and avoid using high-heat hair dryers (use cool or low heat to preserve moisture).
