Hair extension trouble. HELP!!

Samantha • Married, 20, army wife
Alright so i was not blessed with flowing locks like some of yall. For 6 years ive worn hair extensions, ive never had this problem so bad. These are high quality human hair extensions and they matte like crazy!!! I dont know how to fix/ prevent this! I put oil, not a lot of product, brush them, hardly use heat on them, but even like 5 mins after wearing them they look like this. Help please!!!
