heatless curls

I’ve been on a journey to make my hair healthy again , I recently bleached it a little bit , dyed it a light color and cut the split ends completely i would say my hair is pretty healthy right now but the thing is i stopped using heat on it and i’ve been doing heatless curls , they turn out really cute however the problem is i used to get keratin treatments to straighten my hair cuz my hair is naturally wavy so whenever i do heatless curls i could never get the top section of my hair to look good only the mids and ends look good the top of it just looks so messy and weird , does anyone have something similar going on or knows a technique that i could use for it to make it look blended and good? i usually do sock curls using this technique below
