I don’t believe for one second that these extensions are 100% human Indian or Russian hair sourced from temples. As soon as I received my micro rings and ultra tips I washed them with a professional shampoo and conditioner before having them fitted, to my horror they were coated with a horrible silicone which was washing off a strange browny/greenish colour. It took 2/3 washes before the water ran clear!!! Once they were fitted and blow dried they didn’t feel as sleek and smooth as my previous virgin Russian bonds that I’ve had. Overall I am really disappointed in these and won’t be reordering. I doubt the lifespan of these are up to 12 months as stated.
