Fantastic product! Definitely silky hair
Hair serum is a game-changer for anyone looking to achieve smooth, shiny, and manageable hair. This product has truly transformed my haircare routine. With just a few drops, it works wonders in taming frizz, adding a gorgeous shine, and leaving my hair feeling incredibly soft. I love how lightweight it is, so it never weighs my hair down or makes it greasy. Plus, the heavenly scent leaves my hair smelling amazing all day long. I highly recommend adding hair serum to your daily routine for hair that looks and feels fabulous!

Love this!!
Been using this hair serum since I can’t remember. It never disappoint. For me, it’s the best hair serum out there. Great for any kind of weather. My hair is mixed Afro /chemically relaxed hair and I always apply this before and after hairstyling. Keeps my hair soft and not frizz. Thank you Chi! I hope you’ll never change.

Holy grail silky hair product- favourite for years
This is a miracle elixir for my delicate hair! I adore it. It smells beautiful, adds a subtle shine to the hair without weighing it down or making it sticky- you don’t need very much at all. This size really lasts a while considering how little you need for each application. It’s smooths my hair down to prevent flyaways when straight, contains frizz a moderate amount when curly, protects against heat for both blow drying and straightening tools. It’s got such a silky effect on my hair I can’t stop stroking it after I’ve added a little to my strands. It’s a must in my refining as it has been for nearly 10 years. I realise it’s a bit expensive but it really is worth the splurge in my opinion. Even if you only use it rarely for a date or other special occasion, as it’s an assured good hair day in a bottle. Highly recommend you try it for a multi use product that gives such a beautiful result

Chi Silk Fusion Leave in serum.
Definitely recommend this product especially for kinky curly coily hair, or afro coily curly hair eg; 4c, 4b, 3c, 3b, 3c, hair types. Put on a little bit on the parm of your hand, and put it on hair , that's already sectioned ready for Straightening with either eg, hair tongs, Tymo hair Straighteners, or Straighting brushes.The hair will come out bone Straight using this product on dry hair before straightening.I used this product my youngest daughter's hair, who's mixed race ( biracial), 3b coily curly hair type. And the result was really lovely, very Straight with absolutely NO frizz at all whatsoever. Definitely recommend.
