Hello, I’m Kim Jin-Oh, the director of NHI(New Hair Institute)

Hair transplant failures… even though it makes us feel bad just thinking about it, we need to analyze factors that cause hair transplant failures.

In general, three factors are cited.
I’ll explain them separately.
Some are associated with the surgeon who is operating, some with the patient.

The first factor is damaging hair follicles that produce the hair during operation. A hair follicle is a membrane in the root area where hair is formed. In other words, they are like hair pockets. This is a structure that needs to be handled with great care.
It’s very important to make sure that the hair follicles don’t dry up during surgery.

It’s like a fish. Just like how fish die out of the water, hair follicles can only survive outside the body for a limited period of time if the moisture is maintained. Typically, when a doctor extracts or implants hair follicles, it can be damaged. If the doctor doesn’t have much experience with hair transplanting, the possibility of hair follicles getting damaged are a little higher. So it is very important to choose an experienced doctor. Ultimately, choosing a good-skilled hair transplant surgeon will have an effect on these results overall.

The second factor is post-operative complications.
Doctors and medical staffs who assist (the actual) hair transplant are not the only ones that can damage hair follicles. In some cases, the patient is responsible for it.
I told you earlier that for 10 to 11 days after a hair transplant, hair follicle is affected by the external environment. So, the patient has to be careful not to let the transplanted hair fall out due to shock or scratching within the 7-10 days after surgery.

Especially during the early stage of surgery, hair follicles can fall out even with a small shock. As time passes and the hair follicles fully adapt, the chances of them falling are reduced. However, patients need to also reduce the possibility of hair follicles falling off in the first place due to scratching and so on.

You must be careful when putting hats on and off right after surgery and since hair follicles may fall off when the operated area bumps into something you must be cautious the earlier the (post-operation) stage.
Moreover side effects, such as infections and allergic reactions to certain drugs may also decrease the survival rate of the graft.

Such cases are very rare.
Even if it happens, it’s not that much of a concern because it can be treated with medicine early on.

Thirdly, also known as Factor X, there may be cases where the survival rate of graft is not high even when the doctor has performed the surgery with great practice and the patient has managed very well.
This factor is not caused by the doctor nor the patient.
Such cases are called Factor X when the factors are unclear and, hence, called as the unknown factor.

The patient’s body type or growth characteristics can also cause low (hair) growth. There are some people who chronically experience inflammation. Patients with such conditions tend to have blood vessels that overgrow. As a whole, we call factors that inhibits the survival rate of graft that are unknown or unclear X Factor.

It’s actually not easy to control this part, but it’s not very common to judge that the Factor X caused a bad result. Actually there is a limit to how much we can control when it comes to Factor X. However, cases that are determined as failures due to Factor X  are not that common.
So don’t worry too much about this.

In summary, the first of the three factors that cause hair transplant failures is the possibility of hair follicles getting damaged during the hair transplant surgery, which depends on the doctor and the medical staffs’ skills.

Second factor is complications caused by post-op shock or infections in which case patients need to take good care of themselves.

Third factor is Factor X, which is when the factors that inhibit the survival rate of graft are unknown although these cases are rare.

You can summarize and understand like so.
