What are the ingredients?

The label states "with Roucou oil." The rest of the print is too tiny to read:) However, you may find more information at www.davines.com.

Protect against heat?

I use this product almost everyday before blow drying my hair. It smells amazing when you put it on and, when you're finished styling your hair with hot tools. I've believe it has protected my hair and it leaves my hair feeling fresh and light. I have naturally curly hair so when I am done styling I usually use about 1/2 a pump to calm down any frizz. I've had the product for 8 months and I've used half a bottle. A little goes a long way!
