If Stress and MPB Caused Hair Loss, Could There Be Some Regrowth?

In response to a recent post about stress hair loss vs genetic causes:

Dr Rassman,

What if it’s both? Then does it take one year still to see atleast a little reqrowth? You say a year, but in other posts you have said 6-12 months. Are you talking about how long it takes to first start growing, or how long it will take for the hairs to reach their previous length? Thanks

These numbers of 6 or 12 months are in the ballpark of what we see. It’s an educated guess based upon experience over a long time frame. Either number works, but clearly, if you see regrowth in 6 months then you’re on the lower end of the spectrum. Some may see regrowth sooner than others, but there’s no exact date one can mark on the calendar.

If you have stress induced hair loss AND genetic male pattern baldness, the stress might speed up the existing genetic loss. I really have no way to know if there will be regrowth (or how much) after your stress is under control if you have MPB also at play.
