"I already had a hair transplant once, but the result was not satisfactory. Is hair transplant revision surgery possible?"
Hair transplant revision surgery is possible, but it requires much more careful planning than the first surgery. This is because the available hair follicles in the back of the head, which have already been used, and the skin condition altered by the previous surgery must both be taken into consideration. Therefore, in revision surgery, it is very important how efficiently the remaining hair follicles are utilized and how favorable an environment is created for graft survival.
As hair transplants have become more common, the number of people visiting clinics to consider revision surgery has been steadily increasing. I am Director Yoo Hwa-jung of Modi Hair Plant Clinic. In this article, I will explain why hair transplant revision surgery is more difficult than the first surgery, the cases in which revision surgery is needed, and what points are considered to help graft survival.
Key Summary
✔ Hair transplant revision surgery is more difficult than the first surgery due to reduced available hair follicles and scarred skin.
✔ Existing scars cannot be removed, but treatments to improve the graft survival environment can be performed concurrently.
✔ In revision surgery, how efficiently the remaining hair follicle resources are used is most important.
Why Is Hair Transplant Revision Surgery More Difficult Than the First Surgery?
From the perspective of the person performing the surgery, there are largely two reasons why revision surgery is more difficult than the first surgery.
1) The available hair follicles are reduced
A hair transplant is not a surgery that creates new hair where there was none. It is a surgery in which the surplus hair follicles in the back of the head (occiput) that can be extracted — these are called available hair follicles — are harvested and transplanted to the desired area, mainly the frontal area or the crown.
So, for someone who has already undergone surgery once, the available hair follicles in the back of the head are already reduced. In the second or third surgery, even with limited surplus, only the necessary hair follicles must be carefully harvested while minimizing damage to the back of the head.
2) The texture of the skin has changed
| Normal Skin | Scarred Skin |
|---|---|
| Normal skin structure is maintained | Skin structure may have changed |
| Blood flow environment is relatively stable | Blood flow environment may have changed |
| Tissue flexibility is relatively good | Tissue may be firm or have reduced flexibility |
| General transplant plan applies | Individual plan needed depending on condition |
When you touch an area with a scar, the feel is different from skin without a scar. When light is shone on the surface, the way it reflects is also different. Normal skin has fine hairs, some roughness, and structures such as sweat glands, but scarred skin exhibits different characteristics, such as these normal structures not being clearly visible.
Skin scarred in this way recovers more slowly than normal skin and is a relatively unfavorable environment for transplanted hair follicles to become established.
Situations That Lead People to Seek Hair Transplant Revision Surgery
The circumstances of those considering revision surgery vary. In some cases, the density of the transplanted hair did not turn out as desired, and in other cases, many grafts were placed but, for various reasons, only scarring remained and the hair follicles did not survive well.
To summarize, the first surgery is generally performed on normal skin, but from the second surgery onward, there is a possibility that the skin texture or normal structure has been altered by the previous surgery. These factors can slow recovery and make graft survival (the establishment of transplanted hair follicles) more difficult. Accordingly, revision surgery takes more time, and the surgical difficulty itself tends to be higher.
Can Existing Scars Be Reversed?
First, to be honest, scars that have already formed cannot be completely removed. It is difficult to reverse changes that have already occurred. However, the key to revision surgery is making every possible effort, within those conditions, so that the transplanted hair follicles can become established as well as possible. Moving each hair follicle is like transplanting a small piece of tissue, so creating an environment that supports graft survival is very important.
Concurrent Methods to Support Graft Survival
At Modi Hair Plant, we perform the following methods concurrently to help skin under unfavorable conditions.
- Use of blood flow improvement agents immediately after surgery — helps ensure smooth blood supply to the transplanted hair follicles.
- Concurrent hyperbaric oxygen therapy the day after surgery — aims to help skin recovery and support the transplanted hair follicles in becoming established.
- Simultaneous harvesting and injection of hair follicle stem cells — hair follicle regenerative cells are harvested from tissue that is otherwise discarded during hair follicle harvesting, and injected into the transplant area together.
In addition, various other methods to support graft survival are applied concurrently. However, the response and degree of recovery may differ from person to person, so which method will help and to what extent is most accurately determined after examining the actual scalp condition.
Frequently Asked Questions
Does revision surgery always yield worse results than the first surgery?
Not necessarily. However, it is true that with reduced available hair follicles and changed skin conditions, there are more factors to pay attention to than in the first surgery. Therefore, from the second surgery onward, we recommend choosing a clinic even more carefully.
The back of my head was heavily damaged by one surgery. Can I still have hair harvested again?
The possible plan varies depending on the condition of the remaining available hair follicles. The less surplus there is, the more a careful approach is needed—harvesting only as much as necessary while minimizing damage to the back of the head. Whether it is possible and to what extent can be advised after directly examining the scalp.
Can transplants be performed on areas with scars?
Scarred skin recovers slowly and is an unfavorable environment for graft survival, but there are cases where the transplant is carried out while applying various methods to support graft survival within those conditions. However, it is best to understand in advance that the existing scar itself cannot be removed.
When can I have hair transplant revision surgery?
Generally, whether to perform revision surgery is determined after sufficient recovery from the first surgery. Since recovery speed and scalp condition differ from person to person, the exact timing is best determined through consultation.
Points to Check Before Hair Transplant Revision Surgery
□ Are the remaining available hair follicles sufficient?
□ How much is the back of the head damaged?
□ What is the condition of the scarred area?
□ How much transplant volume is needed?
□ Have realistic goals been set?
For Hair Transplant Revision Surgery, Careful Planning Is Most Important
- Hair transplant revision surgery is more challenging than the first surgery for two reasons: reduced available hair follicles and scarred skin.
- Since existing scars cannot be reversed, it is important to establish a realistic plan within the remaining resources.
- Modi Hair Plant aims to support graft survival by concurrently using blood flow improvement agents, hyperbaric oxygen therapy, hair follicle regenerative cell injections, and more.
- Responses may differ from person to person, so if you are considering revision surgery, we recommend a consultation to first check the scalp condition.
Since revision surgery involves handling the remaining hair follicle resources, careful planning is more important than anything else. Please seek thorough consultation before making a decision.
