• The SHISEIDO Aquair Hydration Oil Control Shampoo 600ml is a "dual-effect shampoo for oil control and hydration" under Shiseido’s Aquair sub-brand, designed to solve the core problem of "oily scalp + dry hair" and meet the daily haircare needs of most people. Its core features are:
  1. "Hydration-Oil Balance" Technology: Adopts Aquair’s proprietary "Sebum-Regulating Complex"—a blend of zinc pyrithione (mild oil-control agent), hyaluronic acid (hydrating ingredient), and glycerin. This complex targets excess sebum at the scalp while replenishing moisture to hair ends, achieving "oil-free roots + smooth ends."
  2. Mild & Deep Cleansing: Uses a combination of amino acid-based surfactants and mild anionic surfactants—effectively removes excess oil, daily dirt, and light styling product residue without stripping the scalp’s natural protective barrier. It has a pH value close to the scalp (5.0-5.5), minimizing irritation.
  3. 600ml Large-Capacity Design: Optimized for long-term family use— the durable plastic bottle with an anti-slip grip and easy-pour cap (or pump dispenser in some versions) is convenient to use; the large capacity reduces repurchase frequency and saves costs.
  4. Fresh & Long-Lasting Effect: After washing, hair stays fresh and non-greasy for 2-3 days (depending on scalp oiliness)— the lightweight texture avoids limp hair, while the subtle aquatic fragrance (signature of Aquair) leaves a fresh scent on hair.
  5. Compatibility with Daily Haircare: Suitable for daily use (1-2 times a week for dry scalps, daily for oily scalps) and can be paired with Aquair’s Hydration Conditioner (for dry ends) or Oil-Control Conditioner (for oily scalps) to enhance results.

（specific ingredients subject to product packaging; common core components listed below）：Core Oil-Control & Hydration Ingredients:
Zinc Pyrithione: Mild oil-control agent— regulates scalp sebum secretion by inhibiting the activity of oil-producing glands, absorbs excess oil, and prevents greasy hair without drying the scalp.
Sodium Hyaluronate (Hyaluronic Acid): Multi-molecular moisturizer— penetrates hair cuticles to replenish moisture for dry ends, forms a moisture-locking film, and avoids "oil control + dryness" contradictions.
Glycerin: Humectant— balances scalp moisture, relieves dryness caused by oil control, and keeps hair soft and smooth.
Mild Cleansing Ingredients:
Sodium Cocoyl Glutamate: Amino acid-based surfactant— derived from natural coconut oil, produces mild lather, cleanses oil and dirt gently, and is non-irritating to sensitive scalps.
Sodium Laureth Sulfate (SLES, low concentration): Mild anionic surfactant— enhances cleansing power and lathering ability; used in low concentrations to avoid over-drying while ensuring oil-control efficacy.
Scalp-Care & Stabilizing Ingredients:
Panthenol (Provitamin B5): Converts to pantothenic acid in the scalp— soothes scalp irritation, strengthens the scalp’s protective barrier, and reduces oil secretion caused by scalp sensitivity.
Purified Water: Main solvent— undergoes reverse osmosis and UV sterilization to remove impurities and bacteria, ensuring the stability and safety of other ingredients.
Cocamide DEA: Surfactant booster— improves lather quality, thickens the shampoo’s texture, and enhances ingredient compatibility.
Safety & Mildness Assurance:
"3-Free" Formula: Free of alcohol (stimulates oil secretion), synthetic dyes (causes scalp irritation), and strong synthetic fragrances (uses mild aquatic 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 scalp irritation tests to ensure safety for daily use.

Pre-Use Preparation:
Wet hair and scalp thoroughly with warm water (avoid hot water, which can stimulate oil secretion); gently squeeze out excess water (hair should be damp to ensure even lathering).
Shampoo Application & Lathering:
Take an appropriate amount of shampoo (about 5-10ml for medium-length hair; adjust based on hair length and oiliness) and apply it to the palms.
Rub palms together to create a rich, fluffy lather (lathering first reduces direct friction between shampoo and scalp); then focus on applying the lather to the scalp and roots (where oil accumulates).
Gentle Cleansing:
Use your fingertips (not nails) to massage the scalp in circular motions for 1-2 minutes— pay extra attention to oily areas (e.g., crown, hairline); gently work the lather through the mid-lengths and ends to remove light dirt.
Avoid over-massaging (this can stimulate the scalp and increase oil secretion).
Thorough Rinsing:
Rinse the shampoo thoroughly with warm water— ensure no residue remains (residue can cause scalp itching, oiliness, or dull hair); rinse until the water runs clear and the scalp feels fresh.
Post-Use Care (Optional):
For dry ends: Apply Aquair Hydration Conditioner to mid-lengths and ends (avoid the scalp), leave on for 1 minute, then rinse.
After washing, pat hair dry with a soft towel (do not rub vigorously) and use a hair dryer on low heat (high heat can trigger oil secretion).
