Kindly Note that DHT and AKESO CHI are advance FUE methods . DHT FUE is now having complimentary AKESO CHI FUE in all packages .
So Packages mentioned on website are for DHT + AKESO CHI
you can read AKESO CHI FUE here on this page – https://www.akesohairtransplant.com/akeso-chi/
Here is difference between NORMAL FUE and AKESO CHI FUE
Now we will discuss DHT component of DHT + CHI technique in FUE
WHAT IS DIRECT HAIR TRANSPLANT ? – HOW IT IS DIFFERENT FROM NORMAL FUE ?
Direct Hair Transplant is modification of FUE Technique which aims to decrease time of graft out of body . Read the FUE Technique first to understand this technique.
Why survival rate of hair grafts decrease when we keep grafts outside the body
When hair grafts are removed from your donor area, They lose their blood supply and oxygen supply. When grafts are inserted in the bald area they get oxygen and nutrients by plasma imbibition. During this process, the donor tissues receive their nutrition through the absorption of plasma from the recipient wound bed via capillary action.Blood supply creation takes few days time .
But placing the grafts into slits of bald area takes time . During this time – They are stored in normal saline solution or specific solutions. More time the grafts are stored outside the body – the more injury occurs to them due to depletion of oxygen supply .
LIMMER STUDY
Limmer conducted a study which is quoted by all hair transplant research papers for graft out of body time impact on graft survival rate. It is quoted below in diagram

Out of body time of hair grafts |
Survival rate of hair grafts |
|
2 Hours |
95 % |
|
4 Hours |
90 % |
| 6 Hours |
86 % |
| 8 Hours |
88 % |
| 24 Hours |
79 % |
As you can see that 4 – 6 hours out of body time decrease survival rate below 90 % . Further studies were done and concluded that after 2 hours of storage the suvival rate may be effected .
Few other studies also concluded that graft survival trate after 2 hour of storage can be effected upto 30 % also in some patients .
Our Experience
Practically we have not seen any patient in normal FUE to loss 30 % grafts even after 4 – 5 hours of storage outside the body so studies indicating that it is major factor to get survival rate may be biased . but it can impact 10 – 15 % result in longer surgeries.
What we do in DHT process
In Normal FUE the Hair are harvested from donor area and Kept in normal saline. Suppose 3000 grafts are planned for you . First these 3000 grafts will be harvested from your donor area and kept stored in normal saline / Plasma. After that the implantation of grafts is started in the bald areas. This may require about 3 – 6 hours storage in saline / Plasma. So every hair graft remains outside the body for 3 – 6 hours.
In Direct Hair transplant – we do the slitting pattern (first holes making is done) First in bald area . The hairs are harvested in same technique as FUE but every graft is implanted immediately or within 10 – 60 mins in the bald areas. So Grafts either doesn’t stay outside the body for prolonged period like 2 – 6 hours . It reduces ischemic injury to grafts leading to better graft survival rates.
Advantage of Direct Hair Transplant
The Direct Hair Transplant is basically effort to minimise storage time of graft outside your body.
It maximises the chances of survival of all grafts over FUE.
The Result will be around 10 – 15 % better than Normal FUE in Direct Hair Transplant.
