Care Straight Shampoo — Targeting the Root Cause of Unruly Hair

Most shampoos clean the hair. The STRAINIA Care Straight Shampoo does something more precise: it works to correct the uneven moisture distribution inside the hair core that STRAINIA identifies as a key contributor to distortion, waviness and frizz. Developed in collaboration with a specialist hair quality salon research team, this formula supports the hair from within — so that every wash becomes a step toward smoother, more manageable hair.

This is not a coating or a masking solution. It is a daily care shampoo designed to gradually guide the hair toward a more balanced, ordered state — making it easier to style, easier to control, and easier to love.

Key Ingredients

• Hydroxypropyltrimonium Hydrolysed Keratin (Wool) — Helps repair and strengthen the hair structure from within
• Isostearoyl Hydrolysed Silk AMP — Adds smoothness and shine while supporting moisture retention
• Ceramide Complex (EOP, NG, NP, AG, AP) — Five ceramide types to reinforce the hair’s natural lipid barrier
• γ-Docosalactone & Meadowfoam-δ-Lactone — Heat-responsive lactone ingredients that help control waves and improve manageability
• Glyceryl Glucoside — Supports moisture balance within the hair shaft
• Chamomile & Botanical Flower Extracts — Soothing complex including Roman chamomile, cornflower, linden blossom and St. John’s Wort
• Cholesterol & Phytosterols — Help restore the hair’s natural lipid structure

How to Use

2. Apply an appropriate amount of shampoo and lather gently, working from roots to ends
