It colours your scalp where the hair is the thinest. It is very easy to spray on. Once you determine where to spray, you can use less to cover more. However, it does leave your hair dry-looking. If you perspire lots from your head, then you must be prepared for dripping down your face - it's colouring after all. Also, wash your forehead after spraying - I use a thin layer of paper towel on the roll to protect my eyes & forehead. 123
I hesitated a long time before I used it. Finally, my hairstylist showed me how by spraying onto a towel. It worked from day one. You couldn't see any thin areas at all, so I didn't worry about it. It didn't run down my face. I've used it on holidays in hot climate where my head got hot, but the colour didn't run.
When it dries, it acts like you just teased your hair & it becomes thick. Unfortunately, your hair becomes dry & doesn't swing & shine like natural hair does. 123
