Myth: Trimming Makes Hair Grow Faster
The ends have no say in what the follicle does.

The verdict
Growth happens at the follicle, below the skin. The ends are not connected to that process by any signalling mechanism, so cutting them cannot speed it up.
What's true underneath the myth
Damaged ends tangle, catch on neighbouring strands and can split further along the fibre. Removing them can reduce breakage and improve manageability, so people who trim sensibly often retain more length over time.
That's a retention effect being misread as a growth effect.
