I like to weigh my hair down too... thick/coarse/dry 3ab mix (c is creeping in since I started CG). I condition with Too Shea don't really rinse, put a palm-full of Aloeba as a leave-in & then accordion in a blob of Boots mixed with gel.
No shrinkage with Boots-- possibly because I put so much other weight in?

It a bit producty & dries crunchy but I can accordion it out easily (scrunching frizzes me out.) and by mid day, the product has soaked in completely.

HTH!!
3a/b mix
