My hair has similar curl to Dana's mom's (but longer and brunette w/ no chemical treatments / color).

It can get wild, so I wear it "down" on freshly shampoo'd days. Day two, sometimes down, depending on my mood. Day three / four, it's generally up in a floofy, very high ponytail, so it looks like a curly "puff" on me. LOL!
The year before last I was watching the Shopping Channel and sooooo got carried away...

I decided to try out this:
Ojon Swa treatment to see if it worked on me. For some reason, I thought my hair was thinning...

Uhm, yes, it works! After using the serum as directed, I noticed the teensy wee fine baby hair around my face growing longer. My whole head of hair got stronger and wilder. I stopped using it because it was just too much wackiness going on. LOL!
My SIL saw the difference in my hair, so she uses it. Her hair is straight, uber-fine, oily, and it works well for her, for having stronger, thicker hair.
I also used the
Swa shampoo & conditioner but skipped the fortifying lotion because even the 'poo and conditioner make a difference with my hair.
