Hello, I am 40 years old who used styling gel to keep my hair spiked for over two decades. I just got Provillus for first time due to the fact that I am just starting to lose my hair on top of my scalp and wanted to stop it from losing.. Anyway, I read the instruction and the explanation about styling gel was very vague and brief.. It didn't answer my question.. My question is.. What is proper procedure to apply styling gel? I always apply gel immediately after shower. Now, with Provillus, I should wait til my hair dry then apply Provillus then how long should I wait before applying gel? Or what is best time efficient procedure to work with shower+gel+Provillus? Also, is there any styling gel out there that works very well with Provillus that I could apply both at the same time to save time? Many thanks!
