When you use scissors that aren't completely sharp, or are used for cutting things other than hair, the hair is actually crushed/torn rather than severed neatly. So essentially you are creating a frayed area, much like the frayed end of a rope. It's really not better than a split breaking off, and could be worse. You'd have to look at the hair under a microscope to do an actual comparison. I have a microscope, but like to live in an oblivious state so refuse to do a check on my hair, lol.

I've gotten my routine down to the bare essentials, finally
