I thought I was crazy but I'm glad to read many others had similar experiences with their hair (which is too bad).
My hair tangled up in knots that were unbearable after a couple washes. It was literally a workout getting these knots out of these wefts while watching my $500 spent on hair rip out in clumps. I've had extensions from Sally's that were more tame able...
The lady who helped me find the extensions was kind, courteous, and helpful. I will return to find out the colors I purchased but otherwise I will not be returning for services.
