There's a biological threshold past which no medication—finasteride, minoxidil, or anything else—can revive a hair follicle. Understanding this "point of no return" explains why early treatment is so important.
The Arrector Pili Mechanism
Each hair follicle is attached to a tiny muscle called the arrector pili (this is what makes your hair "stand on end"). Research has shown that this muscle connection is critical to follicle health and regenerative capacity.
As androgenetic alopecia progresses:
- DHT causes follicle miniaturization (shrinking)
- The follicle gradually becomes shallower
- At some point, the arrector pili muscle detaches
- The empty space fills with adipose (fat) tissue
- Once this happens, the follicle can't be pharmacologically rescued
"The follicle isn't 'dead'—it still exists. But without its muscle anchor and surrounded by fat, it can no longer be stimulated to regrow terminal hair by medication."
What This Means
- Slick bald areas: Follicles here are largely past the point of no return
- Thinning areas: Follicles here can often still be rescued
- Recently lost hair: Best chance of recovery
Why Early Treatment Matters
This is why dermatologists emphasize starting treatment early: every month you wait, more follicles cross the threshold. Treatment works by supporting follicles that are still viable. Once they cross over, they're beyond medication's reach.
The only solution for follicles past the point of no return is surgical transplantation—moving DHT-resistant follicles from the back of the head to balding areas.
Don't Wait Until It's Too Late
The best time to start treatment is before follicles cross the threshold.
