Temporary and Permanent Shock Loss after transplantation


Speaking of hair transplants, shock loss is temporary or permanent hair loss as a result of surgical or other trauma.

Temporary shock loss results from trauma to the scalp and can occur for a variety of reasons. This loss is called temporary because the hair grows back after a specified period of time. The reason for shockloss must be resolved at the root before regrowth occurs.


When can shock loss occur and what are the most common causes? Surgical Shock Loss

Shock loss can occur during any type of surgery. In hair transplantation, a typical example of temporary loss is when incisions are made in an area where the hair is very fine and weak due to the miniaturization process induced by DHT (dihydritestosterone) aggression to the hair follicles. This event is considered very common following hair transplantation.

Another example of Shoch Loss is when a strip of skin in the recipient area is taken with the STRIP technique so that it is then dissected and the follicular units to be grafted are prepared. Once the strip of skin has been removed, the surgeon must bring the two ends closer together by sewing them together or placing special staples. If there is too much tension, the blood supply to the occipital area can be drastically reduced, traumatizing the hair on the affected area. Also in this case the shock loss is temporary and once the situation is restored the hair should grow back.


Shock Loss caused by external factors that traumatize the follicles

Another type of shock loss is telogen effluvium typically due to stress, chemicals, poor diet and hormonal disorders (LINK). This is usually caused by external factors that have traumatized the hair follicles. Once the trigger is removed the hair follicles re-enter the anagen phase producing new hair.


Conclusions on Hair Shock Loss

Shock loss can therefore be considered temporary when the hair grows back while permanent when the process does not change. Usually hair follicles subject to permanent shock loss are those already in an advanced stage of miniaturization that would have been lost anyway in a few years.

For this reason it is always necessary to take an anti DHT for a few months before a hair transplant.
