I can absolutely relate! I paid WAY too much money to go to "the best" (yeah right) groomer because the last groomer shaved off his top knot--just after we got him home. He was 4 and a half months old. By the time he was 11 months...(last month) Chase finally had his top knot back. I just wanted it trimmed ever so slightly and I stayed in the waiting room. I COULD NOT HAVE BEEN MORE EXPLICIT to this scissor happy woman. When Chase came out he had the SHORTEST "visor" cut I have ever seen. I almost flipped but somehow held it together. If done correctly, on some dogs the visor cut looks really cute but what was she thinking!!!!!! I can tell you that one month later it has grown maybe 3/4 of an inch. Maybe a bit less. If I had the courage I would try to groom him myself.
