That same thing happens to me. What has helped is having the deva cut. That has really helped with the "carrot top" effect. lol... Seriously, since I have had the cut, my hair gets bigger by the end of the day but not as big as before. I told her that I specifically didn't want it to be so big, so she helped shape it. For me, that was what it took.
3B with some 3a. Fell off but am now back on the CG bandwagon and looking for my HG products.
