Last year I received (almost) the full collection in the John Frieda Full Repair range, including the Oil Elixir. This product claims to reverse the look and feel of damaged hair with every use, as well as smoothing, adding shine and strengthening hair. It advises to use only 1 pump on wet or damp hair for strength and smoothness. To tame flyaways and add shine simply apply a few drops to dry hair, avoiding the roots.
I normally used about 5 to 6 pumps before I had my hair cut, now I dispense about 4 pumps, rub my hands together and comb through my hair with fingers, and any residue left on my hands I use to smooth from mid lengths to ends.
What I like about the John Frieda Full Repair Oil Elixir is that it adds shine and makes my hair feel super soft, as well as being very light, so it doesn't weigh my hair down at all. Do try it if you are looking for a softening, smoothing and lightweight oil.
