Funny coincidence, since I'm using DevaCurl right now. I am really loving the results.
It might be that you're not using enough of the conditioner on your hair. I make sure to use a somewhat generous amount in it and leave it in my hair for 5+ minutes while I do the rest of my stuff in the shower. Then I GENTLY rinse with cold water, but make sure not to rinse all of the conditioner out. For safety measures, I squeeze a bit of the conditioner again and focus on the ends.
I use Arc Angel. It's a stronger hold gel and I love it. Maybe you need Arc Angel instead of the original Angel.
