DHI Hair Transplant in Ukraine

DHI hair transplantation stands for Direct Hair Implantation: the graft is inserted into the skin with a special instrument, the Choi implanter. This is a hollow needle in a pen-like handle. An assistant loads a single follicular unit into it, the doctor positions the needle at the right spot and at the right angle and presses the plunger, so the puncture and the insertion happen in one movement.

It helps to be clear about what the term covers. DHI changes only the implantation stage; the follicles are harvested exactly as in FUE, one unit at a time with a cylindrical punch. In the classic approach the surgeon first creates all the channels in the recipient area, and the team then places the grafts into them with forceps; with the implanter these two steps are merged into one, and no channels are made in advance.

The indications are the usual ones for transplantation: androgenetic alopecia in men with thinning at the frontal and temporal areas, thinning along the parting in women, a high or asymmetric hairline, and scars from injuries or surgery that have long been stable. The method is also chosen for eyebrows and beards, where each hair has to emerge at its own angle.

It does not suit cases where the problem is not a shortage of follicles. With active alopecia areata, unstable scarring alopecia and untreated inflammation of the scalp, surgery is postponed until remission. A poor donor area is a limitation too: the implanter does not increase the number of available follicles, it only inserts them differently. If thinning is progressing quickly at the age of 20–25, the doctor first suggests medication, because otherwise within a few years the operated area will end up as an island in the middle of bare skin.

MediUkraine is a service that finds and coordinates treatment; it is not a clinic. We select the centre and a surgeon with relevant experience, agree a date that fits your travel plans and support you through to the follow-up examination. The decision on the method, the volume and whether the procedure is advisable at all is made by the doctor after an in-person examination of the donor area.

The operation begins with marking. The surgeon draws the future hairline while the patient is sitting rather than lying down, checks it against the shape of the forehead, the movement of the facial muscles and the symmetry of the face, then shows the result in the mirror and agrees it with the patient. The line is deliberately not set too low: thinning continues with age, and the donor reserve has to last for decades to come. At this stage the grafts are counted by zone and the figure is recorded in writing.

Local anaesthesia comes next. First the back of the head is numbed with a ring block of lidocaine or articaine with adrenaline, then the recipient area; a tumescent solution is also injected, which firms up the tissue and reduces bleeding. The first few injections are painful, after which the patient feels pressure and touch but not pain. The dose is calculated by body weight, so "adding a bit more anaesthetic" on request is not possible.

Preparing the donor area and extraction. The back of the head and the temples are trimmed to a few millimetres, treated with antiseptic and anaesthetised, and the patient is laid face down. Follicular units are harvested one at a time with a cylindrical punch 0.7–0.9 mm in diameter, either with a micromotor or by hand. Harvesting stays within the safe zone, where the hair is not sensitive to androgens, and is spread evenly over the whole area: if a lot is taken from one spot, it will look see-through. In two to three hours the team obtains 2,000–2,500 grafts, each with one to four hairs.

Sorting and storage. The extracted units are immediately transferred into a chilled solution and sorted under a stereomicroscope by the number of hairs: single-hair grafts will go into the front line, two- and three-hair grafts further back. Time outside the body is critical for graft survival, so grafts are not stockpiled for long: most clinics begin implantation as soon as the first batch is ready.

Loading the implanters. An assistant picks up a graft with forceps and inserts it into the hollow needle so that the bulb is inside and the shaft remains outside. The tip is chosen to match the thickness of the particular graft, from 0.6 to 1.0 mm: one that is too narrow injures the follicle, one that is too wide will not hold it at the right depth. Between 6 and 15 implanters are in use at the same time, and while the doctor works with one, the team loads the next. This is what sets the pace of the whole operation.

Implantation. The doctor places the needle on the skin at the required angle, punctures it and immediately presses the plunger: the needle comes out and the graft stays in the tissue at the set depth. There is no separate stage of "placing the graft into a ready channel with forceps", so the follicle is less traumatised and spends less time outside the body. Bleeding is lower too, because the puncture matches the diameter of the needle and does not stay open. The angle and direction are set at exactly this moment, and this is what sets the method apart: when channels are made in advance, the graft lies the way the pre-made opening allows, whereas with the implanter the direction of each individual unit is set by the surgeon's hand. In the front line a hair should emerge almost parallel to the skin, at an angle of around 20–30 degrees, tilted forwards; on the crown the direction follows the whorl, and each row changes orientation slightly. An error in angle is not noticeable straight away but a year later, when the hair has grown and sticks out in the wrong direction, and by then it is difficult to correct.

The order of placement matters too. The first two or three rows get only single-hair grafts, set irregularly in a "zigzag", because a straight line looks artificial. Density is then built up: usually 35–45 follicular units per square centimetre in the front zone, 30–35 further back. More does not mean better: overly dense placement impairs the blood supply to the area, and some of the grafts fail to take.

Now for an honest comparison with FUE. The implanter has the advantage where the precision of each unit matters: a finely drawn hairline, the temporal angles, eyebrows and beards, and also densifying between existing hair, since the fine needle passes alongside your own follicles, whereas creating channels with a blade in such an area risks cutting through them. Further advantages are less bleeding and a shorter time for the graft outside the body.

On large areas, however, and where the crown is completely bald, the extra cost is usually not justified. There 3,500–4,000 units or more are needed, the work is done on bare skin, where there is no risk of catching your own hair, and channels set the angle just as well. At such volumes the implanter stretches the operation over two days and adds noticeably to the bill without making a visible difference. The best option is often a combination: the hairline is done with implanters and the rest of the area by the classic method.

Two more points that are rarely mentioned in advertising. Graft harvesting is identical in both methods, so the claim "no incisions and no marks" is a simplification: there are punctures, they are just very small, and they remain in the donor area too. And the implantation method itself does not increase donor reserves: however many follicles can safely be taken from the back of the head is how many there will be, regardless of what is then used to insert them into the skin.

Straight after the procedure the recipient area looks like a field of tiny pinpoint scabs with redness, and the donor area is covered with a dressing. On the second to fourth day some patients find the swelling moves down onto the forehead and eyelids; it is unpleasant but passes within two or three days. For the first five nights you are advised to sleep with the head raised, at an angle of about 45 degrees. The following day the patient is examined at the clinic and the dressing is removed.

The first wash is done at the clinic on the second or third day, and the technique is shown straight away: shampoo is applied with the palm without pressure, water is poured in a gentle stream, the area is not rubbed and the scabs are not picked off. After that the head is washed daily in the same way, and by day 7–10 the scabs come off on their own. Visible hair shafts may come away with them; this is not loss of the graft, the root stays in the skin.

Returning to normal social life usually takes 7–14 days. Redness of the recipient area lasts longer in fair-skinned patients, up to three or four weeks, and it is easier to wait it out at home than to cover it up. Sport, swimming pools, saunas and direct sun are put off for a month, and tight hats and hair dyeing for at least as long.

In weeks two to six the transplanted hairs fall out. This is an expected stage: the follicle itself stays in place and enters a resting phase. In densified areas some of your own hair next to the puncture sites may also fall out temporarily; it usually recovers within three or four months, and the doctor warns about this before the operation, not after.

Growth begins in the third or fourth month, roughly half of the result is visible by six months, and the result is properly assessed at 9–12 months, or closer to 18 for the crown. Comparisons should be made with standardised photos taken from the same angle and in the same lighting: day-to-day changes in the mirror are imperceptible, which often creates the false impression that nothing is happening.

One more point: the operation does not treat the cause. The transplanted follicles are taken from an area that is not sensitive to androgens and they remain, but the native hair next to them goes on thinning, so with androgenetic alopecia the doctor prescribes maintenance therapy in parallel. Some patients need a second session a year later, to densify the result or to cover an area that has thinned in the meantime.
