Suited to anyone with dry, brittle, or coarse hair that needs added moisture and detangling without extra weight, including hair that's dry from heat styling, color, or other chemical services. It's a consumer, at-home product used as a pre-styling step, not a rinse-out treatment, and needs no professional experience to apply.

It functions as a pre-styling primer rather than a standard rinse-out conditioner, which means the moisture and detangling benefits are applied right before heat styling instead of being rinsed away in the shower. The combination of sodium hyaluronate for moisture retention and argan oil for cuticle smoothing is paired with heat protection up to 450°F, so it covers both a hydration step and a heat-styling prep step in one product for hair that runs dry or brittle.

Apply to damp, towel-dried hair, focusing on the driest mid-lengths and ends. Massage or distribute evenly through the hair. Do not rinse out; style as usual afterward.

Can be used daily if desired. For a complete moisture-focused regimen, Redken recommends pairing it with All Soft Shampoo and All Soft Conditioner — not the Acidic Bonding Concentrate system, which is a separate Redken product line.

Pros: sodium hyaluronate and argan oil target moisture retention specifically, rather than just coating the hair; built-in heat protection up to 450°F means a separate heat protectant isn't strictly necessary; leave-in format needs no rinsing step.

Cons: amodimethicone is a silicone-based conditioning agent, so it isn't a fit for a silicone-free hair routine; the formula carries fragrance along with several fragrance-allergen components (linalool, limonene, citral, geraniol, coumarin), which may matter for fragrance-sensitive users; Redken's stated results are tied to using it alongside the full All Soft Shampoo and Conditioner rather than as a standalone product.
