When I was young. Early twenties, back in the early 70's I used to grow my hair long and every time I washed it in the sink or in the tub, I had to pull out clumps of hair from the drain. I noticed at work that the hippies were all losing their long hair. All the guys who were young in the 50's mostly had short hair and weren't going bald. A couple of times I got it cropped and it felt strong and healthy but then let it grow long again. An Italian barber pointed out to me when I was in the chair that I had split ends and was losing a lot of hair. He advised me to keep it cropped for it to grow in stronger. Finally I took heed and bought an electric hair trimmer as in the vid. It works. Saved most of it.
