When my hair started turning white/gray it went from straight to wavy. Over the years I've tried several products and learned to embrace and love my waves. I thought this was an oil when I bought it but was pleased to see that it actually has controlling properties as well. I love how it smooths my waves after I diffuse (I use before and after). However, it smells awful. Really bad. In the bottle it smells great but once I spray it the smell changes - a lot. I use the entire 69 line so it's not something else I'm using that stinks I only smell it once I use the spray. Because I love it so much I choose to assume that the smell doesn't linger once it's dry. I hope I'm right. If it had a better scent I'd give it 5 stars.
