K18 HeatBounce Conditioning Heat Protectant
K18 HeatBounce Conditioning Heat Protectant
K18 HeatBounce is a conditioning leave-in heat protectant that’s interesting because it doesn’t use the K18 peptide—instead it uses other peptides, including a fruitfly-inspired one designed to help protect against heat and mechanical stress. It’s silicone-free and has more of a cream-to-mist texture compared to super watery sprays like Iron Sleek or Dream Coat. The scent is fine and on the softer side, but it’s not my favorite from K18.
