My 62 year old wife had heart valve replacement surgery over a year ago. Since that time she has been steadily losing hair — not in clumps, but rather over her entire head. Her dermatologist advised that this may well be due to the stress of the surgery.
a) Do you agree? if so
b) then what can she do about this,and how long should it last before the hair
I agree with the dermatologist that the stress of the surgery may be causing your wife’s hair loss. We know that those people who carry the genetic hair loss genetics, can precipitate hair loss from stress. Furthermore, certain medications that your wife is probably taking (after the valve replacement) may also be contributing to the hair loss. There is not much you can do about this type of medication induced hair loss if these medications are critical to your overall health. Explore the medications with your dermatologist. You should never change or stop any medication without discussing it with your doctor first.
There is a good chance that the hair will return after the hair goes through its sleep (telogen) cycle. That generally takes 3-6 months. Minoxidil may help as well.
