Hey Beauty Lovers! This is one of the best-selling John Frieda hair products, but somehow I've never given it a go. And since my hair lately has become rather frizzy I decided to finally try out this famous smoothing hair serum. And I really love it! After washing my hair I apply one pump of the serum into still wet hair [just into the lengths and ends, avoiding the roots] before blow-drying it. It also has heat protection which is great! The formula is light and doesn't weight the hair down, leaving it looking smooth and glossy, whilst eliminating frizz and repelling humidity.
