Formulated for people with curly or wavy hair whose curls tend to fall flat, lack root lift, or feel weighed down — DevaCurl markets the CurlHeights line specifically around volume and body rather than moisture alone. It's a consumer retail conditioner (also usable by professional curl specialists), suited to anyone already following a sulfate-free, silicone-free "Curl Care" type routine, since this product is formulated to match that approach rather than break from it. DevaCurl recommends pairing it with the matching CurlHeights cleanser (and optionally the cream) for the volume and frizz results the brand states; used alone as a standalone conditioner it should still work as a basic rinse-out, just without the brand's stated system-level results.

Where a lot of volumizing conditioners lean on lightweight silicones to fake a weightless feel (silicones that can, over time, coat curls and flatten their natural clumping), this one is built without silicones, using film-forming polymers like PVP and Polyquaternium-39 alongside humectants to add body — keeping it consistent with DevaCurl's broader silicone-free, sulfate-free curl care approach rather than departing from it for the volumizing line.

Use after the CurlHeights cleanser, while curls are still wet. Apply the conditioner and use your fingers to gently detangle, gliding it through from the mid-lengths down to the ends. Rinse out; it is not intended to be left in.

Because it's silicone-free, it shouldn't build up on curls the way some volumizing conditioners can over repeated use, and the humectants (glycerin, aloe, hyaluronic acid) add moisture without the heaviness that can flatten curl clumps. The stated 2X volume and 83% frizz reduction numbers, however, are DevaCurl's own system-level claims — they're based on using the cleanser, conditioner, and cream together, so using this conditioner by itself may not reproduce those specific results. It's also a rinse-out product only, so it won't provide all-day hold or volume on its own the way a leave-in or styling cream would, and it contains fragrance along with common fragrance-associated ingredients (linalool, benzyl salicylate), which can be a consideration for people with fragrance sensitivities.
