Wear gloves and a long sleeve shirt so you don’t get bur splinters. If you have MTG use that I pull the burs apart with my fingers and the use a WET BRUSH to got them out.
Coconut oil is really good!
Detangler. However it seems that baby powder works like a charm
You can use a mixture of lotion and fly spray. I know it's wierd but it works
Try using a detangler and use it generously. Slowly try to untangle the hair from he burrs.
