i have the same hair type and always have had issues with starting my locks with twist. this time around i was excited to see that my twist were actually staying. i believe it is becuase i started twisting my hair much shorter than previous times.... So try finger twisting your hair just to test it out or even comb coil and see how it stays if they come out completely then give your hair more time... my hair is currently finger twisted and though all of them will not stay twisted most of them are... if i continue to have problems with the hairs that wont twist im going to tear and rip that area. good luck
