Mega & Giga Session in FUE Hair Transplant (Pros & Cons)

No ratings yet.

Mega-Giga-SessionIf you are looking into having an FUE hair transplant, then you should consider a Mega or Giga Session to get more done in a shorter amount of time.

As time goes on technology is becoming better and better each and every day.

Previously, one would have to race against time to have a hair transplant session done.

Multiple visits to transplant enough hair to fill an area were a common thing.

Now you can have an area, depending on the size of it, filled in with a single visit.

There is not a huge difference between a Mega session and a Giga session.

A decade back, 800 to 1,000 hairs was the benchmark for the number of grafts in . single session.

But now surgeons and their teams are capable of performing 1,500 to 5,000 grafts in long single sessions.

Mega Session vs Giga Session

With mega sessions you can expect approximately 1,500 grafts transplanted in one session. And anywhere from 3,000 – 5,000 grafts depending upon requirements in a Giga session.

Check with your Cosmetic Surgeon about the feasibility of sessions. Since the number of staff needed for this large of a number of grafts differs greatly from regular sessions.

But whether or not you need these larger hair transplant sessions remains a vital question. One can only know if they consult in-person with a surgeon.

An alternative method of determining the degree of hair loss and finding out how bald you are is using the Norwood Scale. But what is the Norwood Scale? Let’s find out.

The Norwood Scale

The expansion of the world wide web has made it easier than ever for patients to find surgeons and practitioners. With medical tourism on the rise, it is not uncommon for patients to enquire about treatments across continents in other countries.

Such a scenario is common for hair transplant too. But when communicating with a doctor over email, skype or telephone, how does one correctly relay the degree of hair loss.

In order to solve this problem and standardize hair loss progressions, surgeons use the Norwood Scale. Although there are many classifications of patterned hair loss, the Norwood Scale remains a popular choice among many surgeons.


Use the above chart to identify your hair loss progression on the Norwood Scale. Normal hair transplant sessions don’t require many grafts.

But for progressed stages of balding like Type 5A, Type 6 or Type 7, the typical number of single session grafts are not considerably sufficient.

Needless to say, Type 5A, Type 6 or Type 7 patients require multiple Hair transplant sessions. This is not an easy feat to achieve. Since even a single session of FUE tends to be extremely demanding for both surgeon and the patient.

An easy alternate for estimating the number of grafts of hair transplant you might require is to use our hair transplant graft calculator.

Pros & Cons

Firstly, the more grafts transplanted, the more hair you will have filling in the bald spots on your scalp. You will also enjoy the fewer visits necessary to have a transplant performed allowing you to save time.

In some cases, you may even be able to save a little money by choosing Mega or Giga sessions rather than going with multiple other sessions.

But these sessions are not without their disadvantages. Firstly, the sessions prove to be physically and mentally demanding of surgeon, staff and patient.

Secondly, not all hospitals or clinics are well equipped with infrastructure and technology to make these sessions a possibility.

Third and the most important drawback is time. While a mega session (1500 grafts) may require anything from 5 – 7 hours, a giga session (4500 grafts)  typically takes 12 – 15 hours.


You really can do more with FUE hair transplants with Mega and Giga sessions with the sheer number of grafts that can be performed in one session.

For one, you require fewer sessions depending on the area you want filled. You can also find out if your cosmetic surgeon offers specials for more numbers of grafts.

It does however have some prerequisites that a patient needs to meet. The surgeon will check the patient’s medical history to ensure he or she is medically fit to undergo such a long lasting surgical session.

The patient must also have a donor site that has ample number of grafts to meed the needs of the hair transplant session.
