Thank you all for your response,
about the toppik, I checked and this version of fiber is kind of bad to the skin, the fact that it is sitting on the scalp and blocking the roots, and is not sticking toyour hair, this is one big problem for me, I also know that toppik is not staying with rain, water or even sweat, I saw this video on YouTube about the guy that used toppik and it start dripping on his face during live show, well this is a fact watch the movie. ??? toppik embarrassed me ??? something like that any way.. you will see. Again I am very happy with the haircubed spray and YES, it is 100% water proof - trust me I am using it, and again if hair transplant doctor say not to use toppik and use haircubed so who am I to say NO. Any way I am just trying to help others with same problem and again thank you all for your comments
