Intense aroma of cinnamon. I used in hair roots mask. Be careful with the oil can leave burns. The masks add a few drops. One dripped into the palm with shampoo 1 drop, and when washed off shampoo hair, I had burns on the body (shoulders, arms). It passed quickly, but the more I do not experiment. Only in the mask for the hair roots. In this case, no burns by washing mask.
