People with fine or flat hair who want detangling and shine from their conditioner without the heavy silicones or emollients in richer conditioners built for thick or coarse hair.

Fine hair tends to tangle easily and go flat fast when a conditioner is too rich, which is the balance this formula is built around: enough cetearyl alcohol and cetyl esters to detangle and add shine, but backed by a starch-and-protein combination aimed at supporting lift at the root instead of just smoothing the ends. It's meant to complete the routine started by the Volume Boost Shampoo rather than stand in for a heavier, deep-conditioning treatment.

• Apply to wet hair after shampooing
• Leave in for 1–3 minutes
• Rinse thoroughly

Pros:

• Lightweight conditioning agents (cetyl esters, amodimethicone) detangle and add shine without the heavy buildup of richer conditioners
• Modified potato starch plus hydrolyzed soy protein are formulated toward root lift rather than pure surface softening
• Vegan and Leaping Bunny cruelty-free, matches the shampoo's paraben-free formulation

Cons:

• Short 1–3 minute contact time (a rinse-out, not a mask) means it's a maintenance conditioner, not a deep treatment for very damaged hair
• Contains isopropyl alcohol and several fragrance allergens (limonene, linalool, hexyl cinnamal, coumarin, benzyl alcohol, amyl cinnamal)
• As with the shampoo, the brand's advertised "system-level" volume results apply to the full routine, not this bottle alone
