*10 POINTS!!* How Do I Keep My Human Hair Extensions From Becoming So Tangled?

I just got extensions put in a few days ago and they're driving me nuts after I shower because they get so tangled. I have the good kind, Remi hair which cost like $130. I do condition it in the shower but its after the shower and when it dries that it becomes so unmanageable and tangled! Should I use that child hair dangler spray? Help Pleease!
