Hello,

This is Dana Plastic Surgery!

Today, we’ll take some time to look at the causes of hair transplant surgery failure and the appropriate graft survival rate before undergoing the procedure.

If you are planning to have a hair transplant, be sure to check out the information prepared by Dana Plastic Surgery!

Causes of Hair Transplant Surgery Failure and the Appropriate Graft Survival Rate

So, what causes hair transplant failure?

Even if hair transplants are performed at too high a density, the graft survival rate can decrease, and if they are transplanted at too low a density, satisfaction will be lower.

In some cases, the amount of follicles collected may have been insufficient compared to the transplant area.

In such cases, it is difficult to say that the hair transplant failed.

However, if the density may be lower, the doctor performing the hair transplant should explain this in advance!

The second cause of hair transplant failure is when the skin or soft tissue suffers excessive damage during the procedure, which can lower the graft survival rate.

The third cause of hair transplant failure is damage to the follicles during the process of harvesting, separating, and sorting the hair.

In such cases, the graft survival rate may decrease, so this can be considered a cause of hair transplant failure!

Dana Plastic Surgery conducts extensive research to reduce hair damage during hair transplant surgery and is doing its best to advance hair transplant techniques.

The fourth cause of hair transplant failure is when the direction or angle of the transplanted hair is incorrect.

If the direction of the transplanted hair is wrong, it can not only look unnatural,

but may also appear as though the hair density is lower.

The fifth cause of hair transplant failure is an incorrect design of the transplant area.

This applies whether the design is asymmetrical or the design was made too wide.

Cause of Hair Transplant Failure ⑥

The sixth cause of hair transplant failure is inflammation occurring in the transplanted area.

However, mild folliculitis can occur during the process of graft survival and regrowth after transplantation,

and it can be temporary and relatively common.

In theory, mild folliculitis is not said to significantly reduce hair growth,

but severe folliculitis can lower the graft survival rate,

so proper care and treatment are necessary!

Cause of Hair Transplant Failure ⑦

The seventh cause of hair transplant failure is when the patient’s expectations are too high.

This applies when the hair transplant results are not bad, but the patient’s expectations are high.

Cause of Hair Transplant Failure ⑧

The eighth cause of hair transplant failure is a constitution that easily develops scar tissue and is prone to scarring,

as well as acne-prone skin.

Acne-prone skin may already have scar tissue forming during the process of developing and resolving acne,

and for people who are prone to hypertrophic scars or have a keloid-prone constitution,

the tissue becomes harder, so the graft survival rate may be lower than that of others!

Cause of Hair Transplant Failure ⑨

The ninth cause of hair transplant failure is neglecting post-operative care.

  • Sleeping in a way that puts pressure on the transplanted area

  • Excessive smoking or drinking

  • Engaging in intense exercise

  • Wearing glasses in a way that presses on the transplanted area and lowers the graft survival rate

  • Undergoing another cosmetic surgery within a few days after hair transplant surgery

Cause of Hair Transplant Failure ⑩

The tenth cause of hair transplant failure is when the reason cannot be identified.

Because the hospital cannot track and verify how the patient managed care over 24 hours after the hair transplant surgery,

there are cases where graft survival is disappointing even though there were no problems during the procedure.

Hair transplant surgery does not have a 100% graft survival rate,

and it is also impossible to make hair density exactly 100% the same.

Therefore, cases with a graft survival rate in the 90% to early 90% range are considered very successful hair transplant surgeries.

In addition, female hairline correction is more difficult than male hairline correction.

Because of issues such as hair direction and design, even if the same density is transplanted, it may appear lower.

However, if you choose a hospital with extensive experience and strong hair transplant skills,

this is a surgery that can still produce the results you want.
