What Are The Causes of a Failed Hair Transplant?
What Are The Causes of a Failed Hair Transplant?
1. Drying of grafts
The hair grafts can dry out if exposed to air for more than 10-20 seconds. This is especially true for smaller grafts, which are more susceptible to damage or drying. This can occur due to various conditions, such as insufficient immersion of the grafts in a physiologic solution immediately after extraction, poor trimming techniques, shifting of the grafts during the transplant process, or poor placement of the grafts.
2. Implantation of the grafts at an incorrect angle or depth:
Wrong angles or depths of graft implantation can result in an unnatural-looking hairline or patchy regrowth.
3. Insufficient growth:
In some cases, the transplanted hair may not grow or grow to a lesser extent than expected, resulting in a failed transplant.
4. Improper wound healing:
Poor wound healing can lead to scarring, impacting the appearance of the transplanted hair.
5. Rejection of transplanted hair:
In rare cases, the body may reject the transplanted hair, resulting in a failed transplant.
Prolonged storage of grafts:
The solutions to preserve the hair grafts must be carefully monitored and maintained in the correct compositions. If the grafts are stored outside the body for an extended period, the risk of damage to the graft.
Inadequate handling of grafts:
Transferring the hair grafts from the preservation solution to the recipient area can take some time. In addition, if the grafts are taken out and stacked on a surface, they may become exposed to air, increasing the risk of damage to the grafts.
Inaccurate placement of grafts:
Proper handling and delicate treatment of hair grafts are crucial for a successful transplant. In addition, accurate placement of the grafts requires a steady hand and precision to achieve desired results.
Depth of graft placement: If the hair grafts are placed too deeply, they may not survive and produce follicles post-surgery. Similarly, placing the grafts too superficially can lead to infection of the hair follicles. Thus, it’s essential to maintain the correct depth of graft placement to ensure successful hair transplant results.
Imperfect hairline:
A hairline designed in a straight line may appear unnatural after a hair transplant.
Improperly placed hairline:
If the hairline is placed too high, it can result in a forehead that appears too large and can continue to experience balding.
Low hairline placement:
Patients who underwent hair transplant surgery in their early 30s may feel that their hairline appears unnatural and low after a few years. In such cases, correcting the hairline may involve removing the follicular units and reconstructing the hairline.
Insufficient hair density:
In some failed hair restoration cases, thicker hair may be present, but the scalp is still visible. Correcting this sparse appearance may involve the addition of more hair grafts to fill the areas where the scalp is visible. This procedure requires a high level of care and expertise.
Wide scar after FUT:
Follicular unit transplantation (FUT) can result in a linear scar at the back of the scalp. If the incision is closed under tension, it may resemble a wide scar. Hair transplantation can be used to make the scar less noticeable.
Stretched Scar:
A scar may stretch due to sloppy surgical techniques or loose stitches during the hair transplant procedure.
Bushy temples:
The temples typically have fine and light-coloured hair. Still, if excessive volume is present due to thick hair implantation following a hair transplant, it can result in a bushy appearance. This can be corrected to provide a more natural look to the temples.
What techniques are used to repair unsatisfactory Hair transplant results?
To repair failed hair transplant surgeries, an advanced modification of the Follicular Unit Extraction (FUE) technique has been developed by experts in the field. The method is a highly effective solution for hair transplant repair; this could be a combination of micro-pigmentation and further FUE surgery using specialised instruments.
