How Can Events Trigger MPB Onset?

Hey Doc,

This is such a great site and I learn so much from here. I had some questions for you. I see you mention that certain events can cause an onset of MPB. Can you elaborate on this, as far as how certain events can cause an early start of MPB. Also, is it possible that a person may never have developed MPB even if he has to genes for it, if that person would have never engaged in an activity that that you say can cause an onset of MPB.

Last question, I asked you once about perscription meds causing hair loss. You indicated that a women should regain her hair back with in a year if the hair loss was caused by the meds. How long would it take for a male to regrow hair that was lost due to perscription drugs?

Thanks!

No one really knows exactly how it happens, but stressful events (such as a major illness) can start a process of genetic hair loss. It can also be such that the genetic hair loss was in progress all along and that the stressful event just made the hair loss more evident (with rapid hair loss during the stressful times), but I doubt that it’s possible to avoid MPB by avoiding these stressful events.

Prescription medications may cause hair loss, but that may be the last item on the list of possible reasons for your thinning hair. For both men and women, one year is a good, safe rule of thumb to wait for regrowth of hair that was caused by medications. But in the real world things are not so simple and there may also be other factors involved for the hair loss.
