FAQ

Hair Transplant Surgery 

How can I know if I am a good candidate for a hair transplant?

Often if your hair loss (anywhere in the body including eyebrows) is not caused by an autoimmune disorder or chronic inflammation, and if your hair loss is permanent (meaning the lost hairs will not regrow, eliminating the need for a hair transplant) then, donor grafts can be planted in the affected area.

That being said, you need to have enough donor hairs (either from your scalp or body) to cover the affected area. You can measure the area of the thinning regions and estimate how many grafts is needed for a satisfactory result (30 grafts / cm2), you can also book an appointment and consult Dr. Nagai directly.

Do I have to cut my donor area hairs (buzz cut) for the operation?

Not necessarily.

For the FUSS method, our team will prepare the donor area while keeping the rest of the scalp hairs long. This helps our patients hide the scar post-surgery.

However for the FUE method, Dr. Nagai and his team are able to extract the donor hairs without the need to cut the donor area hairs short. This allows the patients to cover the post-surgery wounds with their hair. That being said, the operation can be performed more efficiently and quickly with a buzzed donor area and will reduce the strain on our staff. Therefore we recommend our patients to cut their hair short for the operation.

Do I have to cut my hairs near the recipient area for the operation?

This depends on the recipient area. Dr. Nagai and his team are able to make incisions and plant the donor hairs without the need to cut the patient’s recipient area hairs. This allows the patients to cover the post-surgery redness with their hair.

That being said, if the patient needs to transplant grafts near the side of scalp then those areas need to be cut short (or buzzed) since making the incisions for the grafts at the right direction (provided the acute angle of the side hairs) requires a short hair length.

What blood tests are required prior to the operation?

Patients undergoing a hair transplant surgery are required to be tested for the Human Immunodeficiency Virus (HIV) , Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV).

If a patient tests positive for either the HBV or HCV, they can still undergo the hair transplant operation while our staff will take the necessary precautions to avoid transmission during the surgery. However, patients with HIV are not eligible for a hair transplant surgery. 

Can i take the required blood tests prior to traveling to the H&S clinic and send the results?

Yes.

In fact, we recommend our overseas patients to be tested before traveling to our clinics to avoid an unnecessary trip in case of a positive HIV result. Although we offer testing at our clinics as well, the result will often take several days. Patients who are planning to stay for 2 days only are recommend to be tested before hand and send us their results.

I am unhappy with a previous transplant performed by another doctor, can Dr. Nagai revise that?

Yes. If you are a right candidate for a hair transplant, Dr. Nagai can reform and fix the results of an unsuccessful hair transplant surgery. In fact this is a common procedure at our clinic given that many patients are unsatisfied with their previous inept hair transplant surgeon`s skill level.

How long does the entire operation last?

This entirely depends on the number of grafts needed. For an eyebrow transplant where fewer grafts (500 or less) are extracted, the procedure can be over in as soon as 3 – 4 hours depending on each patient`s individual case.

However for a scalp hair transplant where significantly larger number of grafts are needed (usually around 1000 – 3000 grafts per session), the operation can take up to 8 hours.

Will the operation be painful?

In short, mostly no. Dr. Nagai and our team make every effort to accommodate the patients comfort through constant communication during the procedure. Since anesthetics are used, patients will not feel any pain. That being said, since the procedure often takes quite a while, it can take its toll on the patients comfort near the end. But this is temporary since the post-surgery recovery is also mostly painless and patients can return to work the next day.

How many grafts do I need?

This depends on the extent of your hair loss. On average, patients with earlier stages of hair loss (N&H scale of III – IV) would need around 3000 grafts or less to achieve a satisfactory result.

For patients with a more progressed hair loss (N&H scale of V and above), more grafts are needed (anywhere around 4000 – 8000 depending on the patient).

Up to how many grafts can be transplanted in one session?

This entirely depends on the patient`s donor area density and size. With that in mind, usually up to 3000 grafts can be extracted and transplanted in one session in our practice. Although for patients with a larger donor area and density, a slightly higher number of grafts can be transplanted in one session.

It should be noted that some doctors will perform higher graft surgeries in one day (even as high as 7000 grafts in one day). However, these surgeries often do not lead to satisfactory results as the whole operation is rushed with less attention given to the donor area which can lead to over harvestation and a see through scalp. Moreover, the transplanted hairs in this case will have a lower survival rate. The Nagai Method focuses on quality rather than quantity and more attention and care is given to the grafts which leads to a higher survival rate and a more satisfying result overall.

Since around 3000 grafts are transplanted per session, how long do I have to wait before I can have another transplant operation?

This depends on the donor and the transplanted areas. Often in most patients, the second operation will extract donor hairs from the same region (back of the scalp).

Moreover, often the recipient area is close to that of the first surgery as well. Therefore, if the donor area or the recipient area are close then we recommend the patients to wait at least 6 month for the skin to recover before performing the second operation.

On the other hand, if the second operation`s donor area is entirely different (facial or body hairs) and if the recipient area is at a distant from the previous surgery as well (temple and vertex) then the second operation can be performed in as soon as 1 month form the previous one.

When will I see the results of the transplant?

The results of the hair transplant entirely depends on the individual patient case. While some patients start regrowing the transplanted hairs in as early as 5 month, others might take longer. Overall most patients see regrowth at around one year. Often it will take up to 1.5 years for the results of the hair transplant to fully mature.

Post Surgery Care

For how long after my transplant should I quit smoking?

Patients should quit smoking for up to 2 weeks after the operation (and preferably longer) as smoking will interfere with the healing process post-surgery and increase the risk of scarring.

For how long after my transplant should I quit drinking alcohol?

Similar to smoking, patients should quit drinking alcohol for up to 2 weeks after the operation (and preferably longer). Much like smoking, alcohol will also interfere with the healing process post-surgery and increase the risk of scarring.

When can I exercise or return to the gym again?

We recommend patients to rest for at least two weeks and allow the body to heal. This means avoiding any strenuous exercise routine including going to the gym.

Can I travel (or fly) after my operation?

As long as travelling does not include strenuous physical activity and as long as it does not cause direct physical impact on the transplanted area, travelling including flying should not be a concern. We advise our patients to take extra caution and not exert themselves as resting post operation is crucial. 

How should I wash the donor and recipient area after the procedure?

You can start washing the donor area (back of the head, face or body) after removing the bandages.  Begin by using lukewarm water and carefully cleaning the donor area while not causing any friction on the skin to irritate it.

 

Washing the recipient area requires more attention as to not disturb the transplanted hairs. 

For the first 72 hours, the recipient area should be left alone. You can shower during this period, just make sure no water comes in contact with this area.

After 72 hours, you can carefully introduce lukewarm water to recipient area indirectly. Make sure that the shower head does not directly pour water on the transplanted hairs. Instead, let the lukewarm water flow over the recipient area at a controlled slow rate for about 10 minutes (this should be enough to clean the area). After the shower, carefully pat the recipient area dry with a tissue paper taking extra caution to not cause any friction on the transplanted hairs.

After 4 days, you can use a mild shampoo that does not contain any strong ingredients. Usually a normal shampoo is fine (avoid anti-dandruff or prescription shampoos). Make a lather on your hands and carefully place the lather on the recipient area and leave it for several minutes before rinsing.

In the meantime, do not peel off any scabs or irritate the recipient area in any way.

Try to avoid taking hot showers, baths and Onsens (hot springs) for the first 2 weeks as very hot water causes inflammation in the recipient and donor areas and interferes with healing.

When can I start shampooing my head normally again?

You can start treating your scalp normally again after 2 weeks. It is important to take extra caution during these 2 weeks to not irritate the transplanted hairs.

For how long does the redness last after the transplant surgery?

The recipient area will be inflamed for about two weeks after which it will heal and look completely inconspicuous.

As for the donor area, usually it takes a bit longer for the swelling and redness to subside (usually up to 1 month). 

Should I avoid sun light after the operation?

Much like any other cosmetic treatment, patients should cover the surgically affected areas from sun light for at least two weeks to avoid increased scarring.

What can I do to minimize the risk of scarring?

This comes down to reducing inflammation within the body and giving it the nutrients it needs to heal. This means reducing the lifestyle factors that cause inflammation in the first place (smoking and drinking) as well as avoiding unhealthy inflammatory foods (processed nutrient poor foods).   

Avoid the sun light and strenuous physical activities. Increase the intake of nutrient rich anti-inflammatory foods (whole plant foods such as fruits and vegetables) and reduce the intake of sodium as well as foods known to increase blood pressure since a high blood pressure will impede the healing process and increase the risk of scarring.

Should I change my sleeping positions after a transplant surgery?

In general, the transplanted hairs should not be placed under pressure or touched and moved for two weeks. This means that the patient should not sleep with their recipient area directly placed on the pillow as moving while sleeping might cause physical stress to the transplanted hairs.

I accidentally touched the recipient area. Are the transplanted hairs affected?

The transplanted hairs should not be placed under pressure or touched and moved for two weeks. That being said, usually a small disturbance should not cause damage. However, if the follicles bleed due to the trauma, there is a risk of loosing the affected grafts.

The transplanted hairs are shedding. Is this normal?

In a successful hair transplant operation, the hairs should continue growing in their new position for around two weeks after which they will shed and eventually regrow again. If you notice shedding well before the 2 week mark, that can be a sign that some of the shed hairs might not regrow. However, shedding the transplanted hairs around the 2 week mark is completely normal and is expected to regrow.

Other Procedures

Is PRP painful?

In short, No. The PRP procedure is very straight forward. It includes drawing blood from the patient followed by several carefully placed injections. While it is not painful, some patients might find it slightly discomforting. Our staff will make sure that our patients are comfortable and relaxed during the procedure. 

How long does a PRP procedure last?

The PRP treatment is done in as quickly as 30 – 45 minutes. 

When can I expect to see regrowth from the PRP treatment?

Several initial treatments are needed for the PRP treatment to cause significant regrowth. Although individual results will vary, in patients who respond well to PRP the regrowth occurs at around 6 months (sometimes sooner) after several monthly treatments.

Is Regenera painful?

The Regenera® treatment involves extracting several donor hair follicles with their surrounding skin tissues under localized anesthesia, preparing the solution and reinjecting them back in to the scalp. While the procedure itself is not painful (since localized anesthesia is used) some patients might find it slightly discomforting.

How long will the Regenera procedure take?

The Regenera® treatment usually takes up to 1.5 hours.

Will the Regenera treatment leave a scar?

The Regenera® treatment involves extracting several donor hair follicles with a 1 mm punch needle which is a bit larger than the needle used in an FUE procedure. While the larger needle diameter increases the risk for scarring, very few hairs are extracted. This means that the potential scar (if any) will be very small and not noticeable.

When can I expect to see regrowth from the Regenera treatment?

The Regenera® treatment can cause regrowth in as early as one month post treatment. But individual results will vary.
