Totally get it, I fought using a level for hanging shelves forever. Wasted so much time fixing my sloppy work.

My neighbor in Spokane tried that exact vinegar fix on his Samsung last year. It worked for a week before the pump seized completely, and he had to pay for the part plus a service call. Sometimes you're just putting off the real repair.

Yeah, that tracks with what a friend in trust and safety told me.

Tell me about it, claire_hayes35, mine's a fancy paperweight now.

Honestly I bet the water TEMPERATURE changes the hair's surface itself. Like cold water might flatten the cuticle down tighter, locking stuff in. So shine AND color stay better, it's all connected.
