You scrutinize labels and invest in products that are free from harsh sulfates, parabens, and silicones, but never compromise on luxurious performance and tangible results.

Hair That Actually Feels Thicker

Users say their hair 'looks and feels fuller' from the very first wash. The formula builds body from the root up without any sticky or heavy feeling, giving you lasting volume that doesn't collapse by midday.

Finally, Manageable Hair That Listens

Reviewers note it 'tames frizz' and makes hair 'easy to style.' By repairing the inner structure, hair becomes more cooperative, holds styles better, and requires less heat tool manipulation to look polished.

A Clean Scalp That Breathes

The gentle, thorough cleanse leaves your scalp feeling 'incredibly fresh' and 'not stripped.' This balanced environment helps promote healthier hair growth from the foundation up.

Less Hair Left in Your Brush

Customers report 'significantly less breakage' and hair that 'doesn't snap off' when brushing. Stronger hair strands mean you retain more length and see fewer stray hairs on your shoulders.

The Luxury Feel of a Salon Treatment at Home

From the rich, pearlized lather to the subtle, sophisticated scent, the experience is consistently described as 'a spa day in your shower.' It turns daily care into a moment of premium self-care.

Color-Treated Hair Stays Vibrant Longer

The sulfate-free, pH-balanced formula is gentle on hair cuticles, helping to 'lock in color' and prevent premature fading, so your color investment lasts.

No More Weighed-Down, Greasy Roots

Even fine hair types love that it 'cleans thoroughly without buildup.' Hair feels light, clean, and voluminous for longer between washes, free from that heavy, oily feeling.

Resilience Against Daily Damage

Hair becomes more 'resistant to heat' and 'environmental stress.' The protective ceramide layer helps shield hair from the drying effects of blow-dryers, pollution, and humidity.

For best results, follow with the matching conditioner. Timeline Expectations: Week 1: Hair feels deeply cleansed, lighter at the roots, and easier to style.

Born from Kose's Decorté laboratories in Tokyo, this shampoo was created to answer a modern dilemma: how to restore hair's natural volume and health without weighing it down. Japanese researchers identified that daily stress, environmental factors, and styling damage were compromising hair's internal structure, leading to limpness. The solution is the exclusive AQ Repair formula, centered on a patented ceramide complex derived from Japanese rice. Every batch is produced in a GMP-certified facility under Japan's strict Pharmaceutical Affairs Law, ensuring pharmaceutical-grade purity and consistency. It's not just a shampoo; it's a precision repair treatment, consistently ranking as a top choice for volume and repair in Japan's demanding beauty market.

Decorté AQ Repair Volume Shampoo is formulated with a blend of targeted ingredients designed to repair, volumize, and nourish hair. Key components include hydrolyzed silk protein, which penetrates the hair shaft to strengthen and repair damage from environmental stressors and styling, while also imparting a smooth, silky texture. Ceramide NP is included to reinforce the hair's lipid barrier, helping to retain moisture and improve elasticity, thereby reducing breakage and frizz. Botanical extracts such as rosemary leaf extract and chamomile flower extract provide antioxidant benefits, soothe the scalp, and add natural shine without weighing hair down. Sodium laureth sulfate serves as a gentle cleansing agent that effectively removes impurities while maintaining the hair's natural oils. Panthenol (pro-vitamin B5) acts as a humectant to attract and lock in moisture, enhancing hair's softness and manageability. Together, these ingredients work synergistically to restore hair's vitality, boost volume from the roots, and deliver a luxurious, healthy-looking finish suitable for daily use in a premium hair care regimen.
