One product, six jobs. The Thermal Guard Weightless Leave-In is a primer and leave-in conditioner in one, designed for textured hair that needs real protection without the heaviness. It hydrates, detangles, smooths, and shields hair from heat up to 450°F, all while leaving a barely-there finish that works for fine to medium textures.

At the core of the formula is PGenics™ Hydra, a patented peptide technology exclusive to Bounce Curl. This blend of water-loving amino acids is designed to attract and retain moisture deep within the hair, supporting a healthier scalp environment and smoother-looking strands without adding bulk. Mushroom Extract (Polyporus Umbellatus) and Sodium Hyaluronate work alongside it to reinforce heat protection and lock in hydration. Baobab Oil adds a silky, nourishing finish that smooths without grease.

Instrumental testing confirms it reduces hair breakage and protects against heat damage up to 450°F. Whether you air dry, diffuse, or blow dry, this leave-in primes your hair for whatever comes next.
