Kerastase Chroma Thermique is by far the best heat activated leave-in product for color-treated hair. A triple-threat product that smooths, protects, and adds amazing shine without weighing hair down. Add to towel dried hair starting at the ends and working upward, then style with heat as usual.
spray de mode: I love this one by Bumble and Bumble because it is very versitile; you can use it to texturize your hair after it has been blow dried, or spray it onto your hair as a finishing tool to smooth fly-aways.
sheer laquer: This one by Shu Uemura makes the list because of the instant shine results that it adds to the hair. It gives the hair a strong shine while maintaining a firm hold; this one works great for polished looks and updos.
double force: This product by Kerastase is great for layering into the hair when flat ironing it, or when used to break-up curls for added dimension. It’s great because it leaves a mostly matte finish with a more subtle shine.
