Shock loss typically begins 2 to 3 weeks after a procedure. it affects only the transplanted area. you will not see it in areas outside the transplanted area. hair loss outside the transplanted area is due to something different.
in your case, the history is classic for shock loss. i do not know that anyone has noted a percentage of people who have it. I think it very well could be much higher than 20% depending on how you transplant. a very dense transplant will be more likely to produce shock loss. a very limited density with a small recipient site will be less likely. trauma is the primary factor in shock loss. having said this, some people are particuarly sensitive to trauma and are more likely to experinence it.
Shock loss will grow back, but never quite as strong as before the procedure. the hair that grows back will be finer in nature. It will not cover as well as before the procedure. Each time the hair on the top cycles, it is prone to come back finer. this is the process of androgenic alopecia. in my opinion, hairs are like cats. they have a limited number of lives or in the case of hair, cycles. with androgenic alopecia the cycle frequency speeds up. the growing phase shortens, the resting phase is longer, and each new cycle brings a finer, lighter colored hair. eventually the finer hairs begin to grow slower and shorter than the surrounding hairs. finnally, they become fine, whispy vellus hairs that no longer provide any length or coverage. i do not like shock loss because it speeds up the hair loss process, in my opinion. this is why it is best to avoid grafting into hair bearing areas, unless the patient fully understands the risks and wants to make a pre-emptive strike against hair that is prone to fall out. hairs that are already fine may have shock loss and come back so fine that they do not provide coverage. therefore, it is sometimes necessary to graft into fine hair that provides little coverage in order to accomplish a level of satifactory coverage. this would be an example of shock loss that provides a better result than before surgery. shock loss of good, high quality hair is not a good idea because the resulting coverage could be less than the coverage prior to surgery. |
