It’s worth it.
I love it it makes my hair soft and hydrated without being greasy or heavy, and the scent isn’t strong either. It’s perfect for curly hair to make it easy to comb through or straighten. After years, finally an amazing leave-in conditioner has come to the mark

Only hydrating, not full moisture
I've tried using different spray amounts and also just applying it to my hands first and running through the hair - I find this method works best, considering this is a milky product. If you colour/process your hair, this won't be enough moisture. I dye my hair blonde and this product worked decent through the summer heatwaves but once temps got cooler, I had to reach for the leave-in mask version. Not crazy about it and I don't think its worth re-buying as I can always use less amounts of the k18 mask and just have 1 go-to product all year round. In the end, this is case dependent how thirsty your hair is..
