Spiral and Rainshower,
I'm sitting here under my hooded dryer (w/ a processing cap on) with Rainbow brand (colorless henna). It is all natural and smells like fresh cut grass! It was a messy application, but my curls looked super cool all stretched out. I used 2 of the 4 oz of powder and mixed w/ 1/2 cup of boiling water and 2tbs of olive oil.
Spiral, what I'm doing now (cassia, right?) is the gloss that you speak of? So I can do this twice a month or however often I want? I can't wait to see what my results will be like . I'm happy to hear that it has caused your hair to thicken, and that is most certainly welcome over here! I'd love bigger hair. Thats actually my number 1 dream...even more than length (my hair is at APL).
Will post results!!!
