Is DHI a painless technique?

The procedure is minimum painless and causes less irritation than say getting a tattoo. The procedure is done under local anesthesia and the client can relax, listen to music, watch TV, enjoy a light lunch and even nap during the procedure.

Are there any long-term complications of local anesthesia administered before implantation?

No, only localized area of paresthesia can occur which eventually subsides.

Why does the effect of anesthesia wear off faster while working on the hairline?

Trigeminal nerves are thick major nerves, and the bigger the nerve the lesser the duration of anesthesia. It can be prolonged by nerve blocks or giving superficial intradermal injection.

What anesthesia technique is used for body hair?

Local anesthesia, ring block, and/or nerve block are given in case of body hair.

Is there any way to prolong the effect of anesthesia?

Use of supraorbital and supratrochlear blocks is a way of prolonging the effect of local anesthesia. Use of Bupivacaine in a low diluted dose also prolongs the effect.

Is the procedure carried out under a sterile environment?

DHI hair transplant is performed under a completely safe and sterile environment. The procedure room is sterilized with Basilol and all the equipment and tools used are sterilized before the session. Also, strict protocols are applied to all processes and at all levels to guarantee 100% safety.

What instruments are being used during the hair transplant session?

DHI uses single-use disposable punches and needles for every session. These instruments are destroyed after every procedure in front of the patient according to the DHI protocols. Hair follicles are extracted one by one from the donor area using a specifically designed disposable tool with the diameter of 1mm or less.

How frequently should punches be changed?

It can be highly variable. It is advisable to change the punch if too much resistance is encountered.

What will be the size of the instruments used for extraction?

The size of the instruments used for extraction depends on the quality of hair and scalp and may vary between 0.7 mm to 1.00 mm.

Will there be bleeding during the DHI session?

In DHI there is very minimal bleeding when compared with “FUT” or “Strip” surgery.

What is the donor area or safe donor area?

A line drawn perpendicularly from the external auditory canal should define the anterior border of the “safe” area. The superior border – safe donor area begins on the anterior border where it is 6.5 – 7.0 cm wide and steadily narrows as one moves posteriorly. In the midline of the occipital area, the ultimate donor area is substantially narrower than it is superior to the external ear.

What is the maximum permissible duration of extraction?

Maximum permissible duration of extraction should not be more than 4 hours.

Does the time gap between extraction and implantation affect the survivability of grafts and the final outcome?

Yes, a gap of more than 6 hours will hamper the survival of grafts. Also the storage temperature can affect it further. The optimum temperature for storing the graft is 4 degrees Celsius.

Does the hair graft ratio impact the final outcome?

Yes, a ratio less than 1.6 may not yield good results but individual variation occurs.

How frequently should the ice packs be changed during the procedure?

Too frequent a change of ice packs may lead to frequent fluctuations of temperature. Focus should be on maintaining 0- 4 degrees Celsius.

How is implantation done?

Implantation is done with the help of DHI Implanters of varied needle sizes. The hair grafts are loaded in the implanter device and placed directly on the scalp, in the recipient area. The DHI implanter permits the proper placement of all hair grafts at specific angles and the correct depth.

How is the patient positioned during implantation?

The position during implantation is lying down supine with an inclined head to the side or sitting position.

At what depth do you implant the grafts?

The grafts are implanted approximately 4 to 5 mm deep.

What is the angle of implantation?

The angle depends on the direction of existing follicles and it also varies from a very acute angle (15 degrees) on the hairline to 20-30 degrees on zone A & B to 50 degrees on zone C.
