Failure of the hair transplant surgery can occur due to the technical failure by the surgical team or due to sloppy surgical methods. There are many clinics for hair transplantation but unfortunately, hair transplants done by an inexperienced surgeon leads to poor results, low self esteem, patient dissatisfaction and depression.
Correcting these failed hair transplants is challenging because of the reduction in the donor area, bad hairline designs and previously done scarring. It can also be very traumatic for the patient.
The hair graft can dry up in case it is exposed to air for more than 10-20 seconds. Tiny grafts are at much greater risk of damage or drying. This can happen due to the below mentioned conditions:
The solutions meant for the survival of the grafts should be well maintained and they must be in their accurate compositions. If the graft is left out of the body for a long time then the risk of damage is higher.
It takes some time to move the grafts from the physiological bath solution to the recipient area. Thus if the grafts are taken out and piled up on a surface then the grafts end up getting exposed to air.
It is very important to handle the grafts delicately. It requires a steady hand while placing the grafts.
Placing the graft too deep also kills the graft and it can produce folliculitis after the surgery. Placing a graft too deep or too superficially can cause infection of hair follicles.
In some failed cases of hair transplantation, the hair may look less dense and the scalp may be still visible. Implanting the grafts in between can be helpful in correcting the scanty look on the scalp. This procedure needs a lot of care and skill.
Follicular unit transplantation often results in a linear scar at the back of the scalp. If the incision is closed under tension then it can appear as a wide scar. Hair transplantation can be done in this scar to make it less visible.
Loose stitches or improper surgical tools can stretch the scar.
Temples usually have fine and light colored hair. Increased density on the temples after hair transplant due to thick hair implantation gives a bushy look. This can be redesigned to give a natural appearance of the temples.
This technique was previously termed Follicular Unit Extraction and was published in 2002 by Dr Bernstein and Dr Rassman. This technique involves extraction of individual follicular units (FU) or follicles from the donor area and implantation in the recipient area. It established the use of small, circular punch which aided in incision of the skin and separation of surrounding tissue from the graft. This technique gained popularity in next few years after facing initial criticism like any other.
In the year 2018, the term ‘extraction’ was replaced by ‘excision’ in an attempt to emphasise the minimally yet invasive nature of the procedure and avoid misleading patients.
