I have coloured, fine, thin hair that can be on the oily side.
I've used oils before with no luck. They always leave my hair heavy and greasy feeling. This one works perfectly.
Two tips: 1) you MUST shake well, as vigorously as you possibly can; 2) use the least amount possible and work up, you can get too much of this oil very easily.
Follow the instructions, you won't regret it.
