FrizzBgone - Hair Type: I bought this after about the 6th break out of lice at my daughter's school. It is a very light conditioner; it definitely wouldn't be enough to use as a leave-in. It is very light and smells much better than many of the lice repel products. I use it on my daughter's wavy (2a-b) hair to scrunch it in the morning. It doesn't make her hair greasy even after using it for 3 days in a row (without washing). I'll definitely repurchase it, but you should be aware that as a leave-in, it will likely be too light.
