Should she cut her hair before getting extensions?

If a good adhesive is used, those kind of extensions are the best, just make sure it's not wax-based, because it just melts off when it's hot. If it would be wax-based, get it sewn or weaved in. I say yes to the short cut, and she should go as far as to cut it even shorter to take care of the parts that broke off, it looks unhealthy and brittle unless you trim it. Best of luck! =]]
