Leave-in conditioners do not penetrate the hair strand, but are formulated to quickly coat the hair and protect it until the next washing. They are lightweight, and will contain lighter conditioning agents, which add little weight to the hair.
The thin film left behind by ingredients found in conditioners like panthenol, amino acids and Vitamin B5 also help raised cuticle scales on each hair strand to lie flat, which enhances hair color creating luster and shine. Flat cuticles also make the hair strands smoother and detangling much easier.
