In the vast majority of cases, the answer is yes, you can have a second hair transplant.

The procedure can be repeated multiple times actually – the average is 2-4 surgeries in a lifetime.

Technically, you can have as many hair transplants as you like, but the number is affected by the quality of the donor area and the number of hairs extracted in each procedure.

In this post, we will take a look at when a second procedure is necessary after your first hair transplant.

We’ll explore how much time one has to wait in between the sessions, and how second hair transplants affect the donor area.

When do you need a second hair transplant to add density?

Roughly 5000 hairs can be extracted in a one-day hair transplant operation.

This number ensures that the extracted grafts do not spend too much time outside the body and prevents you from getting a second hair transplant scar.

In addition, it keeps the amount of necessary medication within safe limits and allows greater patient comfort during the procedure.

Depending on the severity of the hair loss one hair transplant procedure might not be enough. In such cases, a second hair transplant is needed to achieve the desired coverage.

Hair loss by ageing

A second hair transplant procedure can also be necessary years after the first session if the hair loss progresses.

Though hair loss is in part hereditary, there are a large number of factors that may affect it.

Among others, hormonal imbalance, stress, certain medications, and our lifestyle can affect the hair loss process.

While there are cases when it is slow and gradual, there are others when the hair loss is more periodic.

As hair loss is rather unpredictable, surgeons aim to achieve the best possible result with the session at hand while preserving the donor area for possible treatments in the future.

How long should you wait before having a second hair transplant?

One may enjoy the result of a single hair transplant for years before the natural hair loss process starts again. As such, 3-5-10 years might pass before the second hair transplant becomes necessary.

However, due to the severity of the hair loss, or continued thinning a follow-up procedure might be necessary earlier.

In these cases, your hair transplant clinic will likely recommend waiting around 15 months between hair transplant procedures.

The two main factors affecting the exact length of the period are:

  • The recipient area

After the surgery, the transplanted hair needs 12-15 months to grow out.

Thus, it is best to wait at least a year if you plan to increase the density on the same area, or if you want to address a section that reaches into the previously implanted area.

Firstly, this allows the surgeon to see the previously implanted hairs, ensuring that they do not damage hairs yet to grow out.

Secondly, this way the surgeon can also take into consideration the overall look and plan the distribution better. The recommended waiting period might be shorter if the second surgery is to address a different area of the scalp.

  • The hair loss

If the hair loss restarted after the surgery, you will have to wait until it stops again.

This will help to find the optimal distribution of the hairs during the second surgery providing better results in the long run.

How would the repeated surgeries affect the donor area?

The number of hairs we can transplant – and the number of surgeries we can carry out – varies.

The options are always determined by the density and size of the donor area.

a second hair transplant must not overharvest the safe donor area

In each case, the donor area has a certain limit; a finite number of hairs can be extracted from it.

Each hair restoration surgery will lower the number of hairs in the donor zone and thus, its density.

This is one of the main reasons why you must choose your surgeon and the hair transplant method carefully. 

Higher success rates mean not only that the transplanted hairs grow out in higher numbers. It also means that fewer extracted hairs go to ‘waste’.

With the right technique in the right hands, overharvesting the donor area can be avoided and the doctors take out only as many hairs as absolutely necessary for the good result.

With the FUE2 SafeSystem method we use, around 95% of the transplanted hairs grow out after the surgery.

Naturally, proper aftercare is also crucial to realize this success rate and maximize your second hair transplant results.

One of the best features of the FUE2 SafeSystem is that it does not leave any visible scars even after multiple hair transplants.

The remaining tiny dots are less than 1 mm in diameter, so even short hair provides proper coverage.

Furthermore, during each surgery, the hairs are harvested evenly from the whole expanse of the donor area.

Subsequently, the hair at the back and the sides will have a lower density –but the look will be natural, and there will be no patches.

Second hair transplant before and after

You can see David’s example below and how his three surgeries gradually affected the donor area:


Hair transplant surgery offers a permanent solution to thinning hair.

However, in most cases reaching or maintaining a good result is a process. As such, it might require a second hair transplant surgery over the years. This can be done with the same method, or you may get an artificial hair implant.

The number of hairs available for repeated procedures and the time one has to wait in between two sessions vary greatly.

Besides the result of the previous transplant(s) and the area we would like to implant, it is important to consider whether the hair loss is in progress.

Due to hair loss, it is difficult to predict how many surgeries will be necessary.

Nevertheless, within the limits of the donor area, the hair transplant can be repeated 2-4 times in one’s lifetime.

It is vital to always carry out the hair transplant surgery at hand in a way that offers the best result in the current condition while preserving the donor area as much as possible.

Does A Second Hair Transplant Take Longer To Grow?

A second hair transplant does not necessarily take longer to grow compared to the first one. The growth rate after a hair transplant typically depends on individual healing processes and the overall health of the hair follicles, rather than the number of transplants performed. However, the condition of the scalp and the availability of healthy donor hair can affect the outcome of subsequent transplants.

In which cases is it possible or necessary to perform a second hair transplant?

A second hair transplant may be necessary or desired in cases where the patient seeks increased density or coverage after the first transplant. It’s also an option for those who experience progressive hair loss after their first transplant and wish to address newly thinned or bald areas.
