Fine hair that has been highly processed (coloured, lightened or otherwise chemically treated) and needs bonding care, smoothing and easier detangling without the weight of a cream conditioner. It is a take-home salon product, designed to follow Acidic Bonding Concentrate Shampoo, and it suits people whose hair goes limp or greasy-looking under richer conditioners.

Fine hair that has been coloured or lightened is stuck between two problems: it needs conditioning and bond care, but creamy conditioners flatten it. This one changes the delivery rather than the goal. It sprays on as a liquid, absorbs quickly and rinses clean, so the citric acid and 11% Bonding Care Complex reach the damaged lengths while the hair keeps its lift. Used after Acidic Bonding Concentrate Shampoo, Redken measured up to 1.5x more inner strength and 4x easier detangling, and testers reported 48 hours of volume.

1. Shampoo, ideally with Acidic Bonding Concentrate Shampoo, and rinse.
2. Spray onto wet hair from the ends up to the mid-lengths.
3. Distribute evenly through the hair.
4. Rinse thoroughly.

Pros

• Spray format coats the lengths of fine hair evenly without overloading the roots
• Silicone-free and rinses clean, with no residue or coating
• Citric acid and an 11% Bonding Care Complex target bonds weakened by colour and lightening
• Consumer testing found 48 hours of volume and two days of non-oily hair

Cons

• Probably too light for thick, coarse or very dry hair, which needs more slip
• The strength and detangling figures were measured with Acidic Bonding Concentrate Shampoo, not the conditioner alone
• Contains fragrance and fragrance allergens (limonene, linalool, citronellol)
