The Story

A salon-grade, leave-in repair conditioner engineered for damaged, colour-treated hair. Formulated to strengthen and hydrate bleached or highlighted fibres, it reduces fragility while restoring surface sheen. Citric acid helps rebalance and reinforce the hair cuticle; lightweight silicones and conditioning polymers smooth and protect against heat up to 450°C, leaving hair more resilient with a polished finish.

Apply a small amount to towel‑dried hair, concentrating on mid-lengths and ends. Do not rinse. Style as usual. Reapply to dry hair for targeted smoothing or protection before heat styling.

Water-based formula blends citric acid with amodimethicone, dimethicone and polyquaternium polymers for strengthening, smoothing and conditioning. Free from sulphates; includes lightweight emollients and humectants to hydrate without weighing hair down. Contains fragrance and standard preservative system.

At Ellie Jules, every order is prepared with care to ensure it arrives as beautifully as it was chosen. Enjoy complimentary shipping on orders over €100, with secure, reliable delivery across our full range of jewelry, fragrances, skincare, accessories, and home accents.

Should you wish to return an item, we offer hassle-free 30-day returns on eligible purchases. Our dedicated customer care team is always here to guide you with warmth and discretion, ensuring your experience with Ellie Jules is as seamless as the pieces we curate.
