Care Straight Treatment — Daily Correction for Frizzy, Wavy & Unmanageable Hair

Frizz is not a surface problem. It begins inside the hair fibre — in distortions of structure and uneven moisture distribution that no amount of smoothing serum can permanently fix. The STRAINIA Care Straight Treatment was developed by STRAINIA JAPAN and a professional salon research team to address the root cause: targeting the internal distortion of the hair fibre and equalising moisture from cortex to cuticle. The result, with daily use, is hair that progressively becomes straighter, smoother and easier to manage — not despite itself, but naturally.

93% of users reported noticeable improvement in hair texture in an in-house study of 60 participants.

Key Benefits

• Internal Fibre Correction — Targets and helps correct internal hair fibre distortion, supporting straighter, healthier-looking strands with consistent use
• Frizz, Waviness & Uneven Texture — Reduces all three simultaneously by addressing their shared root cause — moisture imbalance and structural irregularity within the strand
• Keratin & Silk Nourishment — Hydrolyzed Keratin (Wool) and Hydrolyzed Silk AMP deeply nourish and strengthen, restoring what daily styling and environmental exposure remove
• Five-Ceramide Complex (EOP, NG, NP, AG, AP) — Replenishes the hair’s full lipid barrier, sealing in moisture and protecting against ongoing damage
• Heat-Activated Smoothing — Meadowfoam Delta-Lactone activates with blow-dry heat to improve hair alignment and enhance the straight-hair effect
• Botanical Scalp Support — Chamomile, Roman Chamomile, Cornflower, Linden, Calendula and St. John’s Wort extracts soothe the scalp and support a healthy hair growth environment
• Suitable for Resistant Frizz Patterns — Formulated to address multiple frizz types, including complex and resistant curl and wave patterns

How to Use

After shampooing with STRAINIA Care Straight Shampoo, apply an appropriate amount to mid-lengths and ends. Distribute evenly through the hair. Leave for a short time, then rinse thoroughly. For best results, use daily. Follow with STRAINIA Care Straight Serum, Milk or Oil before blow-drying for a complete ritual.

Key Ingredients

• Hydroxypropyltrimonium Hydrolyzed Keratin (Wool) — Cationic keratin that bonds to damaged areas of the hair, reinforcing structure, improving smoothness and reducing breakage
• Isostearoyl Hydrolyzed Silk AMP — Amino acid-rich silk derivative that enhances softness, imparts silky shine and improves the tactile feel of each strand
• Five-Ceramide Complex (EOP, NG, NP, AG, AP) — A full-spectrum ceramide blend that mirrors the natural lipid composition of healthy hair; replenishes the protective barrier and locks in moisture
• Meadowfoam Delta-Lactone — Heat-activated film-former that smooths the cuticle and improves hair alignment during blow-drying
• γ-Docosalactone (Gamma-Docosalactone) — Cuticle-sealing lactone that enhances the straight-hair effect and adds shine
• Botanical Extract Blend — Chamomile, Roman Chamomile, Cornflower, Linden, Calendula and St. John’s Wort soothe the scalp and support long-term hair health
• Dipotassium Glycyrrhizate — Liquorice root-derived anti-inflammatory that calms scalp irritation
