Spontaneous MPB Reversal?

In your experience, have there ever been any documented cases of ‘spontaneous’ male pattern baldness reversal? That is, are you aware of any cases where a bald male’s hair regrew without use of any treatment for hair loss?

No, but if you are aware of any complete reversals, I would love to know.

I have seen near complete reversal in some rare cases where men under 35 years old have reversed their balding after taking finasteride. Some men with telogen effluvium may lose hair temporarily, but it is rarely in a typical pattern and is more diffuse.
