I have fine, thin, wavy hair that can be frizzy and almost straight in winter and curly in summer. This is the best conditioner I have ever found. It moisturizers my hair, but does not weigh it down. I have stopped trying any others, I will use this for life! I love that it has a flat top--you can store it upside down so you don't have to fight to get the conditioner out of the bottle. And it has a nice light scent and a little bit goes a long way.
