How to colour and restore your hair extensions

so what I do first is I choose the hair colour that I want them to be 

I chose the drugstore superior preference infinia blue black colour from L'Oreal

brush your hair extensions and put them in a bowl, not to big
then follow the instructions on how to colour the hair

Boil some water with a tablespoon of coconut oil and half of the conditioner bottle that comes in the box, set aside

when the hair is ready, rinse them really good and don't worry if they're tangled, with the boiling water mixture it will make it easy to untangle, add them to the boiling water for 5 to 10 minutes

brush the hair gently and leave them to dry 

ta- da !!!they look and feel like new !!
I had my extensions for 3 years they went from blonde to brown and now black
