About a month ago, I made a nice blowout after watching a video on youtube. Just wash your hair and airdry it in twists. (I used my shea/coco mix for moisture).
I think I made 4 big sections in my head and made 4 twists in each section--16 twists in total. Make sure they are completely dry before you untwist.
Then comb out each twist with a big comb very gently.
You will get a nice, fluffy fro with no heat!
Also, if you don't fully comb out some of the twists you get some nice waves along with the fro which looked too cute!
I took pics but my 'puter crashed and I lost all of my pics I have ever taken!
This is the video that helped me:

Good luck!
