  1. @theworldofcraig reviewing Kérastase Elixir Ultime at 06:35 in a YouTube Shorts video
    • The Elixir Ultime from Kérastase is their jewel in the crown. In my opinion, it's extremely overpriced and I will tell you why I think it's very overpriced5:41
    • It's basically dimethicone. It's about £60. It has two different sorts of dimethicone in it and then it is camellia oil. There is no scientific data to suggest that camellia oil makes the hair stronger, that it makes it grow longer or anything like that6:35
    • I think the Elixir Ultime is great and I have tried it and I think the texture is lovely but it is occlusive so it doesn't really do much to the structure or strength of the hair8:18
    • It will make it feel lovely and if you love the way it makes your hair feel hoorah8:28
  2. @theworldofcraig reviewing Kérastase Extraordinary Oil Midnight Serum at 07:28 in a YouTube Shorts video
    • This has coconut oil in it which some people would say has better properties on the head than the camellia oil. It is a little bit more researched if you like7:11
    • Ultimately, these have very similar ingredients lists. They're both L'Oreal7:28
    • The extraordinary oil the nighttime serum will do very similar things to the hair8:35
  3. @theworldofcraig reviewing Kérastase 8H Magic Night Serum at 10:03 in a YouTube Shorts video
    • Interestingly, this serum is not meant to go on the scalp. It's meant to go on the hair9:08
    • The thing that's doing the heavy lifting in this is niacinamide
    • The second ingredient again is dimethicone that is the basis of a lot of the Kérastase serums because it makes the hair feel really slippery10:03
