First I mixed the cinnamon with one of my V-05 conditioners.
FINAL REVIEW: It did not work AT ALL. My hair looked exactly the same as it did before the treatment. It didn't even look lighter in the sun! Maybe my hair is too coarse and thick to take to the treatment, because as you can see, I applied A LOT of cinnamon paste to my hair!
See? Still dark! The bright side is that cinnamon is said to have other great properties. It is said to prevent hair breakage and reduce hair loss. So I ended up with supposedly stronger, cinnamon-y hair (my hair STILL smells like a sweet potato pie)! But no lightening. So don't waste your good cinnamon on this one.
