Description
Inflammation, fibrosis, scalp tension, “toxins”… they show up next to hair loss, so someone calls it the hidden root cause and sells you a device, massage tool or supplement to fix it.
But presence isn’t causation.
Here’s what those theories can’t explain: hair transplanted from the back of the head into the “tense, inflamed, fibrotic” front keeps growing normally for decades. Same scalp, same blood supply, same everything. The only thing that changed was the follicle itself.
It’s called donor dominance, and it’s why genetics and hormones (DHT), not scalp tension, drive male pattern hair loss.
Before you buy the next “root cause” fix, ask: does this explain why transplants work?
