Curl Therapy is a lightweight, leave-in conditioner from L'ANZA's Healing Curls range, built specifically for curly, wavy, and coily hair that needs hydration and detangling without added weight. Rather than rinsing out, it's worked through damp or dry hair and left in through diffusing or air-drying.
The formula centers on a vegan butter complex -- mango, moringa, and capuacu butters -- alongside plant-based protein derived from peas and potatoes, intended to supply amino acids that support curl strength and bounce. L'ANZA also includes mineral-fortified PCAs (a moisture-binding ingredient class) to help curls hold onto hydration between washes, plus a mix of botanical extracts -- sunflower seed, meadowfoam seed, milk thistle, cactus, and olive oil -- included for shine and everyday antioxidant support. The brand markets the formula as vegan.
Because it's a leave-in rather than a rinse-out treatment, it's meant to go on towel-dried curls and stay in through the drying process, with a separate styling product (such as others in the Healing Curls line) layered on afterward for hold and definition. It tends to suit curl types on the drier or coarser side more than fine, straight hair, since the butter-based formula adds noticeable richness. It's sized at 160 mL (5.4 fl oz).
