Just had my first succesfull second day hair today! Lol
What I did was tie my hair into a "pineapple" the night before so my curls would stay in tact the next morning. Then when I take out the scrunchie in the morning, I shake out my curls gently and wet my hands under the sink and basically, start scrunching my hair until it's fairly wet. Then I apply a LITTLE more of my LaBella styling gel and diffuse and I'm good to go! If I notice some frizzies creeping up, I grab a little more leave-in which is my regular rinse-out condish and apply that to my trouble spots.
I have never used CurlJunkie so I can't really give my opinion on that but if you're looking for a nice CG spray, I recommend Giovanni LA Hold Spritz.
