I had hair transplant procedure a week ago and I’ve note that the hair is still growing in the grafts. Does this mean the hair has been accepted and that it will continue to grow?
Following hair transplantation hair in the grafts will continue to elongate for about 10 days. Some of this may be continued hair growth, but it also reflects a move toward anagen effluvium. In anagen effluvium the dermal sheath begins to contract and move toward the surface of the skin much like an accordion. This shortening of the dermal sheath will push the bulb of the hair shaft toward the surface of the skin. Therefore, some of the elongation of the hairs is not due to growing, but rather due to a contraction of the dermal sheath toward the skin surface.
Once the dermal sheath contracts, the hairs will either begin to shed on their own beginning in two to three weeks after the transplant. Some of the hairs will continue to rest on the surface of the skin for a prolonged period of time. Eventually the scalp skin will either begin to form a wall around the resting, non-growing hair, or the scalp will form a pustule or pimple like reaction that will eventually burst and the non-growing hair will exit the skin with the exudate from the pimple or cyst like structure.
It is probably a good idea to minimize the number of the cyst like structures that you get because they represent unnecessary inflammation. Inflammation may not always be a good thing. In theory inflammation might sometimes lead to an autoimmune response toward one’s own hair and this in turn may compromise future graft growth.
In order to minimize inflammation, we generally recommend that patients begin removing non-growing hair fragments beginning three weeks after the hair restoration procedure. The best way to manage this is to aggressively wash the scalp with soap and a wash cloth. Non-growing hair will come out easily like removing a pin from a soft stick of butter. Growing hairs on the other hand must be plucked and it takes a good bit of force to accomplish this.
Sometimes hairs do continue to grow following a hair transplant without ever going into the resting phase, but it is unlikely that you will see more than 10% go into the resting phase. It is far more likely that the hairs will shed. Occasionally hairs almost shed, but then continue to grow. We can easily recognize these hairs because they have a dark tip that is coarse followed by a narrow constriction that is of lighter color. This is followed by a gradual darkening of the hair shaft and increase in hair diameter once again. We call these hairs that exhibit signs of this trauma pol pinkus hairs and they are a sure sign of recently transplanted hairs that have continued to grow.
