I love this range ,especially the hair repair serum which is oil based . it really helps with split ends and frizz . i spray some on damp hair before styling . it also acts as a heat protectant . i have frizzy hair so i also smooth Some onto dry hair and it helps tame the frizz and give me a sleek and shiny look. I dont have a problem with it weighing down my hair or making it look oily. Its quite lightweight as well and smells incredible.
