Tonic could easily apply through the whole scalp as the great design of the nozzle of the tonic bottle which could quickly and equally spray on to large area of my scalp. I could feel the tonic absorbed into the scalp as it dry quickly after applying it. Tonic doesn’t gives oily feeling but only leave refreshing smell after applying it. Anyway it is a good tonic to be recommended, bought 1 extra as gift for my friend.
