My wife has been cutting mine for decades.
Once, a long, very long time ago, when my wife was still a girlfriend,.”….oh, let me cut your hair….”
NEVER AGAIN. So bad it was, she said “oh that’s going to take awhile to grow out”.
For the last 20 years of my wife’s beautiful life, only *I* trimmed her hair, straight across at the waist. I trusted NO ONE else, based upon a couple scissor-happy butchers hacking off way too much.
