Doesn’t work for straight hair; helps hair health
It did not at all add volume to my straight hair. I will say that since using my hair does feel healthier. Although, it’s hard to say if it’s the product itself or a combination of products I’ve been using to work on my hair health. Love the smell.

Didn’t like it
I wanted to love this product but it’s a no. It’s way too expensive and I wish I would have returned it. It caused my scalp to itch, my hair to frizz and no volume. I wouldn’t buy it again.
